Introduction Introduction Congratulations and thank you for purchasing the SoundLink DRS 1212 I/O PCI Multi-Channel Audio Interface card. The 1212 I/O features ADAT optical input and output, S/PDIF input and output, and stereo analog input and output, all of which can be used simultaneously (with compatible software). An ADAT sync input allows software applications to synchronize directly to ADAT timecode, without need for external devices.
Installation English Installation Installing the 1212 I/O is simple and straightforward. However, to make sure that you don’t damage the card or the computer, please read the instructions on pages 2-11 completely before performing the installation. They’re short, they’re sweet, and they’re even sprinkled with a few zippy graphics–the perfect accompaniment to a brief coffee break.
Installation Hold the 1212 I/O by its edges Did we already mention that the 1212 I/O uses a whole bunch of delicate electronic components? Well, OK, so we’ve said it again. To avoid damaging those lovely little silicon jewels, always hold the 1212 I/O by the edges of the card, or by the metal jack panel (where the connectors are). Don’t touch the electronic parts, the PCI connector pins, or any of the traces on the board (those little silvery paths that run between the components).
Installation IMPORTANT: Within each group (input or output), all of the jumpers must be set the same way: either all installed, or all removed. English When the jumpers are installed, the level is set to -10 dBV; when they are removed, the level is set to +4 dBu. The 1212 I/O ships from the factory with all six jumpers installed, so that both input and output are set to -10.
Installation All jumpers within a group must be set the same way: either all installed, or all removed. 5. If you have removed any jumpers, store them in a safe place. They’ll be necessary if you ever want to switch the card back to -10dBv operation. Installing the 1212 I/O card in your computer Please consult your compatible computer’s manuals for detailed instructions on installing a card in your specific system. The instructions below are a brief overview of the installation procedure.
Installation English With the card installed in the computer, you’re now ready to install the 1212 I/O software. Installing the 1212 I/O software (MacOS) The 1212 I/O includes three important pieces of software for MacOScompatible computers. The 1212 I/O extension allows software to talk directly to the card, and also provides compatibility with the Apple Sound Manager.
Installation Restarting allows the 1212 I/O extensions to be loaded into the system; the extensions must be loaded before the card can be used. 11. After successfully re-starting with the 1212 I/O extension loaded, reenable any installed virus detection extensions. Virus detection software will only interfere the first time that the 1212 I/O extension loads. Installing the 1212 I/O software (Windows 95) The 1212 I/O includes several important pieces of software for Windows 95-compatible computers.
English Installation 8. In the Run dialog box, type the following command: A:\setup.exe 9. Press OK. The Korg 1212 I/O Software Welcome dialog will appear. 10. Follow the on-screen instructions. The on-screen instructions will walk you through the rest of the installation. Audio connectors Korg engineers worked valiantly to squeeze an incredible number of inputs and outputs onto the 1212 I/O’s relatively small jack panel.
Installation ❶ Stereo analog input This input is used to bring analog signals into the 1212 I/O. You can connect this to the output of a mixer, microphone pre-amp, synthesizer, and so on. To allow use with a wide range of equipment, the analog input may be configured for either +4 dBu or -10 dBV signal levels. For more information, please see “Analog levels: +4 or -10” on page 3.
Installation English one end, which connects to the 1212 I/O, and fans out to a pair of female RCA connectors. One of these connectors is white, and labeled “In,” while the other is yellow, and labeled “Out.” S/PDIF stands for “Sony/Philips Digital Interface.” The S/PDIF format carries two channels of digital audio, and is commonly used for transferring stereo signals between DAT recorders, digital signal processors, digital musical instruments, and so on. S/PDIF input.
Installation “Clock Source,” on page 25). Connect this to the word clock input of the slave device. Most commonly, this will be connected to the Word Clock input of an Alesis BRC; this is necessary when transferring audio from S/PDIF input to ADAT output in a BRC-equipped system. As with the Word Clock input, above, the Word Clock output requires a shielded, video-quality cable, with 75-ohm or greater impedance.
System Configurations English System Configurations This chapter is intended to provide a quick guide for integrating the 1212 I/O into a variety of different setups. By its nature, the instructions here are brief; for additional detail, please consult the manuals of the other digital audio hardware and software being used. Word clock settings The great majority of technical support questions regarding the 1212 I/O are the result of incorrect word clock settings.
System Configurations In Deck, set the Sync Mode to Digital. For more information on word clock settings in audio software, please see “Setting the word clock source in digital audio software,” on page 16. 3. When playing back into the S/PDIF device from a digital audio program, set the 1212 I/O’s word clock source to Internal (or ADAT, if you generally use an ADAT system as the master clock source).
System Configurations Korg 880A/D English The 880A/D provides the 1212 I/O with an additional 8 high-quality analog inputs. The 880A/D connects directly to the 1212 I/O’s ADAT optical input, so setup is very simple. First, connect the cables: 1. Connect the Word Clock output of the 1212 I/O to the Word Clock input of the 880A/D. 2. Connect the optical output of the 880A/D to the optical input of the 1212 I/O. Next, make all the word clock settings: 3. On the 880A/D, set the CLK. SOURCE to EXT.WCLK.
System Configurations 1. Connect the 1212 I/O’s optical cables to the 168RC’s Dig A ports. 2. On the 168RC, press the MISC button, and scroll down until you reach the CLK Source parameter. Set this to DIG-IN-A (the 1212 I/O). This selects the 1212 I/O as the word clock source for the 168RC. 3. In the digital audio program, set the 1212 I/O’s word clock source to Internal. Korg 168RC and ADAT This setup combines the 1212 I/O and an ADAT with the Korg SoundLink DRS 168RC digital mixer.
English System Configurations 1. Connect the 1212 I/O’s optical input and output to an ADAT I/O card on the 02R. 2. On the 02R, Press the Digital I/O button. 3. Go to the Word Clock Select page. This page shows a list of all the installed I/O cards, and allows you to select a pair of channels from any card as the master clock source. You can also select the dedicated word clock input, or the internal clock. 4. Set the 02R to use the ADAT 1/2 channels from the card connected to the 1212 I/O. 5.
System Configurations Make sure that the program’s sample rate matches the external clock source When you record or play back audio data using external clock sources (such as the S/PDIF, ADAT, or Word Clock inputs), the sample rate is controlled entirely by the external source, and not by the digital audio program’s sample rate parameter. Because of this, you must make sure that the external clock source is actually set to the same sample rate as the digital audio program.
System Configurations English Below is a nifty little diagram, showing the 1212 I/O hooked up in a simple system with two ADATs and a BRC. If you have more ADATs than shown here (lucky you!), just pretend that this diagram’s ADAT #2 is the last one in your chain. ADAT Timecode Conditioner The 1212 I/O’s ADAT Timecode Conditioner is a small device which fits between the ADAT 9-pin sync cable and the 1212 I/O’s ADAT timecode connector.
System Configurations Setting the word clock source on an ADAT system ADATs have three settings for word clock source: “Digital,” “Internal,” and “External.” Digital means that they sync to an external clock through their optical or 9pin inputs, if they are connected to another ADAT optical device (such as the 1212 I/O); if there are no other devices connected, then they use their internal clock. Internal means that they use their internal clock, regardless of any signal at the optical input.
System Configurations NOTE: The original ADAT defaults to “dig” at power-on. English BRC (with either original ADAT or ADAT XT) When using the BRC with either original ADATs or ADAT XTs, the BRC supplies the word clock to the ADAT system. The BRC can use its internal word clock, or word clock from its 48kHz input. This is controlled by the Clock Source parameter, under the EXT SYNC button.
System Configurations When one device sends out a bit of data (like the ball being thrown to the other juggler), the other needs to be ready to receive it. If the data is being sent even just slightly faster than it can be received, bits will be lost, causing errors in the audio (like the ball being dropped).
System Configurations English 1212 I/O, the audio will play back from the 1212 I/O at the exact same speed as the ADAT, and the duration of the audio will stay exactly the same. If you switch the Clock Source to Internal or S/PDIF, however, the duration of the audio will probably change very slightly. Over the course of a several minute song, this timing offset can become noticeable.
1212 I/O Utility 1212 I/O Utility In the MacOS, you can use the 1212 I/O Utility to set up the card for use with the Apple Sound Manager; in Windows 95, you can use it to set up the card for use as a wave device. You can also use the Utility as a stand-alone application for such tasks as transferring audio data between S/PDIF and ADAT formats, re-routing tracks in an ADAT system, and generating “digital black.
1212 I/O Utility English Korg 1212 I/O Utility (Windows 95) Current Card 1212 I/O In PCI Slot (MacOS) You can install multiple 1212 I/O cards in a single computer. The 1212 I/O Utility displays parameters for one card at a time; this selects which of the Cards you are currently viewing, identified by the PCI slot in which the card is installed. 1212 I/O Card (Windows 95) You can install multiple 1212 I/O cards in a single computer.
1212 I/O Utility Word Clock & Sample Rate Clock Source When connecting multiple digital audio devices–such as the 1212 I/O, an ADAT system, and a S/PDIF device–it is important that the word clocks of the devices be locked together. If the clocks are not locked, the audio may be marred by pops and clicks. The 1212 I/O can lock to incoming clocks from any of its digital inputs, or it can generate its own clock. For more information, see “A few words on word clock,” on page 20.
1212 I/O Utility English maximum value of 0dB, the volume of the input signal will be unchanged. At lower values, the volume will be reduced. At the minimum value of OFF, the input signal will be completely muted. In general, it’s best to leave the input pad set to 0dB, and attenuate only when necessary to avoid digital clipping. If you’re using an external mixer, you may find it more convenient to reduce the output level of the mixer.
1212 I/O Utility Output L Analog L, Analog R, S/PDIF L, S/PDIF R, ADAT 1-8. This selects the 1212 I/O output channel which will be routed to the Sound Manager’s left output channel. Output R Analog L, Analog R, S/PDIF L, S/PDIF R, ADAT 1-8. This selects the 1212 I/O output channel which will be routed to the Sound Manager’s right output channel. Channel Routing You can adjust the volume, phase, and output routing for each of the twelve audio inputs.
1212 I/O Utility English Mute All Pressing this button mutes all the inputs, so that all inputs receive only the purest, cleanest, most eminently silent digital black. Pressing the button again restores the previous settings of the window. Through All Pressing this button sends all inputs to their corresponding outputs, so that ADAT 1 in goes to ADAT 1 out, ADAT 2 in to ADAT 2 out, and so on. All volumes are set to full, and all phases are set to normal.
1212 I/O Utility for which the file has no data, then its parameters will be set to default values. If a file contains parameters for only a single card, the data will always be loaded, even if the card is now in a different location. Close This command closes the current document. If the document has been edited, you will be prompted to save your edits before the document is closed.
English 1212 I/O Utility Quit (MacOS) or Exit (Windows 95) This command quits the Korg 1212 I/O Utility. If the current document has been edited, you will be prompted to save your edits. Edit Menu The editing commands only affect numerical parameters, such as the channel volumes and analog input trim. They do not affect any menu selections. Undo In the MacOS, this command is disabled. In Windows 95, this will undo the last numerical edit.
1212 I/O Utility Toolbar (Windows 95) The Toolbar appears at the top of the window, and includes buttons for creating a new file, opening a file, saving a file, cutting, copying, and pasting, and showing the “About 1212 I/O Utility” box. For more information on each of these features, see their descriptions above. The Toolbar can be shown or hidden by checking or un-checking the “Toolbar” option in the View menu. Status Bar (Windows 95) The Status Bar appears at the bottom of the window.
Applications English Applications This section provides brief, step-by-step instructions for the major functions of the 1212 I/O. Many of these can be performed using the simple 1212 I/O Utility program. Digital audio software written for use with the 1212 I/O should allow you to access to all of the parameters provided in the Utility program, so these tricks should work in those programs as well. All of the following instructions assume that you’ve followed this single, very important step: 1.
Applications For this reason, when using the 1212 I/O with some Sound Manager programs, you may want to mute the Auto-Routing Mode by pressing the Mute All button in the 1212 I/O Utility. Whenever you edit the current settings in the 1212 I/O Utility, the 1212 I/O remembers these settings, and continues to use them for the Auto-Routing Mode as long as the computer is on.
Applications English Setting the Sample Rate parameter lets the S/PDIF device know what rate to expect. 3. Set the Clock Source to ADAT. 4. Set the ADAT system’s word clock to Internal. For more information, please see “Setting the word clock source in digital audio software” on page 16. If you are using the Alesis BRC, read the instructions under “Using the Alesis BRC: 1212 I/O output to ADAT input,” on page 36.
Applications before the machine containing the source tracks. This is because the source machine will block the output of the 1212 I/O, in favor of its own output. For instance, let’s say that you have a three-ADAT system, with the 1212 I/O at the end of the ADAT chain. If the source tracks are on ADAT #2, you can record the S/PDIF output onto ADAT #1, but not onto ADAT #3. If the source tracks are on ADAT #3, you can record the S/PDIF output onto either ADAT #1 or ADAT #2.
Applications note: ADAT timecode synchronization and clock source,” on page 20, for more information. English When synchronizing to ADAT timecode, the 1212 I/O’s word clock source cannot be set to Internal. SMPTE and MTC offsets have no effect on ADAT timecode Some ADAT devices, such as the Alesis BRC and Fostex RD-8, allow you to enter SMPTE and/or MIDI Time Code (MTC) offsets from the normal ADAT timecode.
Applications several tracks have been selected on ADAT #2, making it into a transmitter. Notice how this blocks the output of the 1212 I/O. To avoid this situation, you need to clear the BRC’s digital I/O settings. To do this: 1. Press the BRC’s EDIT button. 2. Press the BRC’s DIGITAL I/O button until you see the “Select source with track buttons” page. 3. Make sure that no tracks are selected. If necessary, de-select any currently selected tracks.
Applications English For instance, let’s return once again to the configuration of three ADATs and a 1212 I/O, in which the 1212 I/O is connected at the end of the chain, so that it sits in the optical loop between ADAT #3 and ADAT #1. The 1212 I/O can record the optical output of ADAT #3, and ADAT #1 can record the optical output of the 1212 I/O. ADAT #2 does not directly communicate with the 1212 I/O at all; it can only record the output of ADAT #1, and play into ADAT #3.
Sound Manager (MacOS) Sound Manager (MacOS) Introduction Digital audio software designed for the 1212 I/O can take advantage of all the card’s advanced features, such as multitrack input and output and ADAT timecode synchronization. Even if a program has not been specifically written for use with the 1212 I/O, however, you may still use the card for digital or analog sound input and output through Apple’s Sound Manager.
Sound Manager (MacOS) It will become hilighted. The 1212 I/O will now be used for input to Sound Manager-compatible programs. English If you have multiple 1212 I/O cards installed in your computer, each card will appear separately in the control panel. We recommend that you select the same card for input and output. 4. Select “Sound Out” from the menu. The Sound Out page appears, with the on-screen instruction, “Choose a device for playback.” 5. Select the 1212 I/O icon. It will become hilighted.
Sound Manager (MacOS) For more information on these parameters, please see the chapter titled “1212 I/O Utility,” beginning on page 23. 14. Optional: Press the “Mute All” button to mute the direct inputoutput channel routing. When using the 1212 I/O with the Sound Manager, the input-to-output routing of the Auto-Routing Mode can sometimes be distracting. To avoid this, you may wish to mute the routing.
Wave Devices (Windows 95) English Wave Devices (Windows 95) Using the Korg 1212 I/O as multiple wave devices Through the 1212 I/O’s standard wave device driver, the card can be used by almost any Windows digital audio program. The 1212 I/O appears as six full-duplex stereo cards, one for each output pair. Programs which support the use of multiple cards have simultaneous access to all 12 audio inputs and outputs, up to the limits of the program itself.
Wave Devices (Windows 95) However, the Windows 95 multimedia system keeps track of each audio device simply by a number, generated by the order in which they were initialized. It is this number that is stored in a digital audio program’s input and output assignments. You can check the device order by looking at the audio “preferred device” menus in the Multimedia Properties control panel. In these menus, the devices are shown in order (although no actual numbers are displayed).
Wave Devices (Windows 95) English Korg 1212 I/O Wave Device Control Korg 1212 I/O Wave Device Control window 1212 I/O Card The 1212 I/O Wave Device Control displays parameters for one 1212 I/O card at a time. This menu displays the PCI bus number and PCI bus device number of the currently selected card. You can install multiple 1212 I/O cards in a single computer. Separate wave device settings are maintained for each installed card.
Wave Devices (Windows 95) input sensitivity for the analog inputs; for adjusting audio input level from ADAT or S/PDIF sources, we recommend that you use an external mixer. Balance Slider Each stereo output pair has a balance slider, which controls the relative output levels of the left and right channels. The balance control is active only when the device’s Vol/Bal On box is checked. For more information, please see “Vol/Bal On,” below.
Wave Devices (Windows 95) all of the devices in the group have received the start command from the digital audio program. English Note that this synchronization applies only to input and output pairs on the same 1212 I/O card. Auto Sync When Auto Sync is checked, synchronization happens automatically. Whenever you select or de-select a 1212 I/O input or output pair in your digital audio program, Auto Sync will add or delete the pair from the synchronization group.
Wave Devices (Windows 95) Clear All Pressing this button clears all of the “Vol/Bal On” check-boxes at once. Custom Synchronization Custom Synchronization window In general, enabling the Auto Sync check box should give the best results. In some cases, however, you may wish to have manual control over the wave device synchronization. The Custom Synchronization windows offers just that; you can individually set record and playback synchronization for each input and output pair, as described below.
Wave Devices (Windows 95) English Sync Play Similarly, each of the six output pairs has its own Sync Play check-box. If one or more of these is checked, the 1212 I/O will not start playing or recording until all of the checked devices have received the “start play” command from the digital audio program. When playing from multiple output pairs simultaneously, make sure that each active output’s Sync Play box is checked, and that all of the inactive outputs’ Sync Play boxes are not checked.
Troubleshooting Troubleshooting General Cannot select 1212 I/O within digital audio program (MacOS) Is the 1212 I/O extension installed in the System Extensions folder? This file must be installed in order to use the 1212 I/O. Is the 1212 I/O card seated properly in the PCI slot? Cards can sometimes become unseated if the computer is moved, or if the card is jostled during installation of another card (or RAM, disk drives, etc.).
Troubleshooting Audio English Audio has pops and clicks OR The same audio sounds different between ADAT, S/PDIF, and Analog inputs or outputs OR ADAT or S/PDIF inputs or outputs sound distorted Make sure that the word clock settings are correct for all hardware and software, including ADAT-compatible multitracks, digital mixers, S/PDIF devices, and digital audio software.
Troubleshooting the external clock source. This is because when audio is recorded into a digital audio program, the audio files are stored with the program’s current sample rate setting - even if the real sample rate is different, as in the example above. This can result, for example, in a file containing 48kHz data, but marked as 44.1kHz. Avoid this by always making sure that both the digital audio software and the external source are set to the same sample rate.
Troubleshooting English Card stops, audio squeals, or channels shift (Windows 95) The 1212 I/O card relies on being able to transfer small amounts of data across the PCI bus at regular intervals (roughly 12,000 times per second). If other devices tie up the PCI bus for extended periods of time, this can prevent the 1212 I/O from completing a transfer before the next scheduled transfer. If this happens, the audio stream will be corrupted.
Troubleshooting Make sure that all word clock settings are correct for all connected hardware and software, including ADAT-compatible multitracks, digital mixers, S/PDIF devices, and digital audio software. In Deck, is Trigger Sync turned on (in the Options menu)? Deck requires that Trigger Sync be enabled when working with ADAT timecode. In the MacOS, Is AppleTalk turned off? AppleTalk should be turned off whenever using timing-critical music applications.
