A U D I O P H I L L E O 1 & 2 U S E R 1 Chapter M A N U A L Introduction T hank you for purchasing the Audiophilleo1 or Audiophilleo2 USB to SPDIF transport. These devices are designed to be the strongest link in your audio chain, giving you peace of mind and allowing you to focus on other aspects of improving your audio system. Simply connect the USB port to a PC and the BNC output connector to your DAC S/PDIF input and you are ready to listen.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L One infrared remote receiver cable with 2.5mm audio connector One 3.5mm stereo audio to dual mono adapter for 12V trigger outputs (option) Getting Started There is no need for installations or configuration on supported operating systems (Linux, OSX, and Windows XP/Vista/7, iPad). Just plug it in and the default USB audio operating system drivers should install automatically. Note that under XP, Linux and OSX sample rates of 44.1, 48, 88.2, 96, 176.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Note: When first plugging in the Audiophilleo1, it will use a volume setting of -72dB for safety. Please increase the volume to the desired level. Figure 1. Connections (Items not to scale) Audiophilleo1 user interface The Audiophilleo1 has several additional features such as BitPerfect, volume control, infrared remote receiver and 12V trigger, and includes a joystick and OLED display to configure those and other features.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L To get familiar with the main screen, please plug in your device and press and hold the joystick for help on the main screen.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 2 Chapter Media Player and PC Setup T here are a variety of operating systems and media players available. Their detailed description is beyond the scope of this manual; however it summarizes high level concepts. Windows XP/Vista/7/8 The Audiophilleo1&2 are compatible with the USB audio device driver included with windows XP/Vista/7/8. However, to achieve 176.4 and 192 KHz sample rates with Vista/7/8, you will need to install our custom driver.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Some media players like Windows Media Player use only DS and only play back at the sample rate selected in the Windows audio settings. Other media players such as JRMC and foobar2000 will automatically switch the sample rate to that of the audio file it is playing as long as you don’t use DirectSound (DS) output. Note that for foobar2000 WASAPI playback you should obtain WASAPI plugin version 3.1 or above.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Apple OSX OSX does not require the installation of a driver. Audio Midi Setup is used to configure default audio devices and sample rates. There you should always set the Audiophilleo’s format to “2ch – 24bit” – even if you are playing red book CD audio. When and Audiophilleo1 is first plugged in, the computer may ask you to identify a keyboard.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 3 Chapter Advanced Audiophilleo1 Features T hese features are available in the Audiophilleo1 only. The following information is intended to augment the Audiophilleo1 online help system. To obtain online help, simply push and hold the joystick for 1 second on any screen. Dithered Volume Control The Audiophilleo1 support volume attenuation of 0dB to -72dB. Setting the volume is done using the computer volume control.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L happen when one un-plugs and re-plugs the Audiophilleo1 too quickly. In this case the Audiophilleo1 will always set the volume to -72dB for safety. Note: Changing the volume using the remote control feature simply sends a volume up/down command to the computer. It is up to the computer what volume steps size to use. Therefore, different operating systems will exhibit different volume step sizes.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 2. Using the joystick, enter the BitPerfect menu and then follow the on-screen instructions to play the WAV file. This basically involves playing one of the BitPerfect files after making sure your PC is configured correctly. When you play the file, the screen will briefly show “Searching for test audio...” and then start scanning from 0% up to 100%.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L VirtualCable VirtualCable allows the audiphilleo1 to change the edge transition speed of the SPDIF electrical signal between <700ps and 15ns in 5 steps. This is similar to changing SPDIF cables for the purpose of affecting the sound. We only care about overlapping waves when the DAC is measuring the digital signal level transition.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L JitterSimulator JitterSimulator gives you a way of hearing what jitter would sound like in your system. The JitterSimulator feature is in the settings->SPDIF->JitterSim menu. The joystick may be pushed up/down in order to select the setting. The Audiophilleo1 supports 2 jitter levels: Level Jitter 0 Normal operation with <8ps RMS period jitter and <8ps RMS phase jitter integrated from 10Hz to 100Khz.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L “Not at 48Khz” is used to override “Sample Rate” at 48Khz and send 0000. This is useful because some DACs have bugs causing them to not lock on otherwise. Other features The Audiophilleo1 has various other capabilities that include: Putting the computer to sleep and waking the computer from sleep via remote control. Swapping L/R channels for easier wiring. Phase Inversion allows for phase inversion of the audio signal.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 4 Chapter Troubleshooting and Status LED T he Audiophilleo1 and 2 are equipped with an LED which provides various status messages to the user. In addition, the Audiophilleo1 may temporarily display status or error messages in lieu of the volume display on the main screen. Note that under normal operating conditions these messages and LED patterns may be ignored. LED Codes When first plugging in the device, the LED will immediately flash very briefly.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L If the computer is in a sleep state, then the LED will be permanently on. All status messages start with one L flash. All error messages start with two L flashes. The table below lists all possible LED status codes: Flashes Meaning LS 44.1Khz sample rate set LSS 48hz sample rate set LSSS 88.2hz sample rate set LSSSS 96hz sample rate set LSSSSS 176.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Solid ON for Firmware upgrade mode initiated (displayed on ap1 after 10-20 seconds firmware->update menu is entered or on ap2 when firmware file detected in audio stream. 1.23 above The table below lists all possible LED error codes. Because they are fatal errors, these error codes are repeated indefinitely once they occur. Under normal usage these codes should never occur. If you see these errors, please contact technical support.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 5 Chapter Firmware Update O ur devices are designed with modular firmware that is easily updated. Updates will be released based on feature requests and bug reports. Please let us know if you have any requests. We will try to include any reasonable requests in the next firmware update. Firmware files are simply special 44.1/24 audio files in WAV format. For updates to work, the playback sample rate must be 44.1 KHz 24 bit.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 44.1/24, then iTunes will again resample once the AP is plugged in. To avoid this, temporarily change the sample rate of your internal audio device to 44.1/24 as well. Note: If your current firmware version is 1.15 or less, please be sure that the firmware.wav file plays only once and that nothing else plays after it. Audiophilleo1 Update Procedure The firmware->about screen will show the currently running firmware version.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L MS Windows does not fully probe a USB audio device each time it is powered up, so to check the current firmware version, open Control Panel, Manage Audio Devices. Then double click on the Audiophilleo, click Properties, click Details, and select the property called Bus Reported device description. Upgrading if your firmware is 1.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L LSSLL means that the firmware file is identical to the already loaded firmware. No update is possible. LSSSLL means that the firmware file was corrupt. Most likely the computer is modifying the audio stream. Please check that you are using a 44.1 sample rate without re-sampling and other distortive effects happening on the computer. AP1 Note: After a failed firmware update, unplug and re-plug the ap1 or re-enter the firmware menu with ap1.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 6 Chapter Specifications Jitter 2.5 ps RMS phase jitter integrated from 10 Hz to 100 kHz. This is measured using a TSC 5120A phase noise analyzer. 8 ps RMS phase jitter integrated from 1 Hz to 100 kHz. This is measured using a TSC 5120A phase noise analyzer. < 5 ps RMS period jitter (< 15 ps peak-peak) This is measured using a WaveCrest DTS with a sample size of 8000.
