Introduction Thank you for purchasing the DiO 2448 PCI Digital I/O Card by M Audio. Please take the time to read this instruction manual — we want you to get the most out of your DiO 2448. This manual contains valuable information on how to install, configure and operate your card. As soon as your DiO 2448 based system is up and running, you will be enjoying the world of digital audio from your computer. What’s in the Box? Your DiO 2448 box contains: This instruction manual.
About the DiO 2448 The DiO 2448 inputs and outputs support digital audio streams as wide as 24 bits, the highest resolution available at this time of printing. At sample rates of up to 48kHz, the DiO 2448 S/PDIF inputs may record a digital signal from your DAT, MiniDisc, CD player, or external A/D converter. The DiO 2448 S/PDIF and Analog outputs may be used to monitor the incoming S/PDIF signal or to output digital audio from your software applications. Below is a simplified block diagram of the DiO 2448.
The DiO 2448 also supplies two CD-ROM analog audio headers internally, with both popular formats supported. These provide a connection to the analog output of your computer’s internal CD-ROM drive (if you have one installed). Only one of these headers may be connected at a time. CD-ROM analog audio may be monitored at the DiO 2448’s Analog output only and may not be recorded. In order to retrieve data from an audio CD-ROM, we recommend the use of a “CD Ripper” software program.
The DiO 2448 Adapter Card 1. 2. 3. 4. 5. 6. 7. Coaxial S/PDIF Input: This RCA connector receives a S/PDIF stereo signal from an external coaxial S/PDIF device. Coaxial S/PDIF Output: This RCA connector transmits a S/PDIF stereo signal to an external coaxial S/PDIF device. Optical S/PDIF Input: This TOSlink connector receives an optical S/PDIF stereo signal from an external optical S/PDIF device.
Hardware Installation To mechanically install the DiO 2448, follow these steps: 1. 2. 3. 4. 5. 6. 7. 8. 9. Turn off your computer. Remove the computer’s cover and position the computer so that you may easily access its PCI slots. Select the PCI slot where you will install your DiO 2448 card. Make sure it is a PCI slot. If you don’t know what “PCI slot” means, check the owner’s manual for your computer.
2. 3. 4. 5. 6. The ‘Add New Hardware Wizard’ will now ask how you want to find the driver. “Search for the best driver for your device” is already selected. Click ‘Next>’. Windows will give you a selection of locations to search. Make sure that ‘Floppy disk drives’ is checked, or click on the check box to do so. Insert the “DiO 2448 Windows 95/98 Driver” software disk into your disk drive. Click ‘Next>’. The ‘Wizard’ reports that its Windows driver file search has found the M Audio DiO 2448.
4. A:\ drive (if your floppy drive is a different letter, change it at this time). Insert the DiO 2448 Windows 95/98 Driver software disk into the drive and click OK. Windows will start to copy files, with a progress indicator on the screen. Once this process completes itself, your DiO 2448 will be ready for action. After completion of the driver installation, Windows may require you to restart Windows.
Windows Driver Configuration Windows displays the DiO 2448 driver status in the Device Manager page of the System Properties dialog box. The Systems Properties dialog is opened via the Windows Start button. Select Settings | Control Panel to open the Windows Control Panel. Select “System” from the Control Panel to open the System Properties dialog box, then click on the “+” next to Sound, video and game controllers to open the list of devices, the DiO 2448 being a device of that nature.
Using the DiO 2448 with your Software Applications Once the DiO 2448 is installed and the driver software properly loaded, it is ready for use with your music application software. Some of these applications require you to highlight or enable the DiO 2448 drivers within the program, and others may have a utility that analyzes or “profiles” the audio cards in your system and enables the drivers. Within your software application, the DiO 2448 record (input) device typically appears as “DiO-2448 Record”.
Below are descriptions of each control panel function. While reading this section, it might be helpful to reference the DiO 2448 block diagram in the ‘About the DiO 2448’ section of this manual. SPDIF-OUT Source: This switch determines which audio stream will be transmitted at the DiO 2448 S/PDIF outputs. Its setting affects only the S/PDIF outputs and not the Analog outputs. Choose “SPDIF-IN” to monitor the DiO 2448’s active S/PDIF input directly.
SPDIF-In Format setting. To do this, click the “Analyze” button and follow the on-screen instructions. You will be prompted to start playback on your S/PDIF device. After you have pressed play on your S/PDIF source device, press the Analyze button and the driver will automatically configure its receiver to the proper input format. You may also choose to cancel this operation. If your S/PDIF input signal is valid, you will receive a message stating that “Your S/PDIF signal is OK for recording now.” Press OK.
The middle fader “Wave Output” controls the level of the WAV software playback, prior to the master volume fader. The rightmost fader “CD Audio” controls the monitor level of the analog CD-ROM input, again prior to the master volume fader. NOTE: If these three controls do not appear in the WSS mixer, then you must go into the WSS program settings and configure them properly. To do so, select Options | Properties from the Volume Control menu. The Properties dialog box will then pop up.
a number of mixes from a DAT into an editing program, performing the appropriate edits, and transferring the edited material back to DAT. Transferring From DAT TO DiO 2448 1. 2. 3. Connect the DAT coaxial S/PDIF output to the DiO 2448 coaxial S/PDIF Input using a good quality digital cable. Since only one S/PDIF input may be active at a time, leave the DiO 2448 optical S/PDIF input disconnected. Connect the DiO 2448 analog outputs to some type of amplified sound system.
4. 5. 6. 7. Open the WSS mixer. Verify that the Volume Control fader is set loud enough and “mute all” is not selected. After verifying that your sound system is set to safe levels, start your DAT material playing. You should immediately hear the DAT material monitoring through the sound system. If the monitored sound is extremely noisy, you will need to reconfigure the S/PDIF input. To do this, open the DiO 2448 Control Panel.

Connect the DiO 2448 coaxial S/PDIF output to the DAT coaxial S/PDIF input using a good quality digital cable. Connect the DAT analog outputs to some type of amplified sound system. The sound system should be equipped with speakers or headphones. Open the DiO 2448 Control Panel software.
Troubleshooting This section addresses potential problems that can occur in all operating system environments, with emphasis on hardware troubleshooting. Within the PC environment there are a limited number of hardware resources (I/O addresses, IRQs, and DMA channels) available for use. Since audio cards require many resources, most audio card installation problems arise from unavailable or improperly set resources.
“Verifying Windows Driver Installation” section of this manual. It might take more than one PCI slot relocation to find an open IRQ. If relocating your card to another PCI slot does not cure the DiO 2448’s conflict(s), then you must do some further investigation to determine the exact nature of the conflict(s). Again, go to the Windows Device Manager, highlight the DiO 2448 or other devices with conflicts and click the “Properties” button at the bottom of the Device Manager window.
see another device showing up on the same IRQ as the DiO 2448 (such as a video card, SCSI adapter, or USB Host Controller), then it is possible that this is the source of the conflict. Typically, if you move one of the conflicting cards to another PCI slot, an IRQ conflict will disappear.
Troubleshooting Tips for Frequently Asked Questions Problem: No Sound. Possible Cause 1: There is a resource conflict with another device in your computer. Check the DiO 2448 configuration (Address, IRQ) against those of the other devices on your computer. If necessary, change the settings for the one or more of the devices Possible Cause 2: The DiO 2448 drivers are not properly installed or the DiO 2448 is not selected as the current audio output device.
named “DiO-2448 Record” and “DiO-2448 Playback” as your active audio drivers. The manner in which this selection is made is dependent on the application (each one is a little different). Problem: I’m getting some pops and clicks in my audio recording. Possible Solution: Some accelerated graphics cards use excessive amounts of system bandwidth, preventing the recording buffer of an audio card from keeping up with demand. This can cause clicks in the recording.
