INTRODUCTION
MINIMUM SYSTEM REQUIREMENTS
SOFTWARE DOWNLOAD OR UPDATES
Congratulations on your purchase of DigitalLife U2AUDIO7-1. The DigitalLife U2AUDIO7-1 supports analog and digital
audio for 2 to 7.1 channel audio applications; the external USB sound card provides a cost-saving upgrade from built-in/
on-board sound that turns desktop/laptop sound into a home theater-ready audio solution.
Note: The audio adapter’s SPDIF optical pass-through port supports two-channel audio; This port does not support 5.1
or 7.1 audio.
Note: The U2AUDIO7-1 has been designed to accommodate common headsets which feature a 3.5mm TRS headphone-
and 3.5mm TRS microphone jack. XLR based microphones (even if adapted to a different interface) will not work with
this audio adapter. 48V of additional Phantom Power is needed to make this work. The U2AUDIO7-1 does not provide
Phantom Power.

TROUBLESHOOTING
This section provides solutions to problems you may encounter during installation or normal use. This includes:
• Problems with Sound
• Problems with Simultaneous Playback/Recording
Problems with Sound
Problems with Simultaneous Playback/Recording
■ No sound from headphones.
Check the following:
• The headphones are connected to the Headphone jack
• In the Speakers tab of Audio Control Panel, the Headphones option is selected in the Speaker Configuration box.
OR In the speakers and headphone selection of Entertainment Console, the Headphones option is selected.
■ No audio output when playing digital files such as .WAV, MIDI files or AVI clips.
Check the following:
• The speakers' volume control knob, if any, is set at mid-range. Adjust the volume mixer settings in Entertainment
Console, if necessary.
• The powered speakers or external amplifier are connected to the Line Out jacks.
• The speakers and headphone selection in Entertainment Console corresponds to your speaker or headphone
configuration.
■ No audio can be heard from the Line In or Mic In jack source when doing recording.
Do the following:
• In the Mixer selection of Entertainment Console, unmute the Line In/Mic In input.
An error message appears when recording and playing back simultaneously. This may occur due to data transfer
limitations if your computer is using a USB 1.1 connection. It may not be possible to playback or simultaneously
record and play back, content at the highest bit rate and/or frequency supported (24-bit, 96 kHz). Select lower bit
depth and sampling rates for reduced CPU consumption and lower USB bandwidth requirements. Select lower
settings if you encounter performance problems or if you run out of USB bandwidth. Lower sampling and bit depth
rates, however, usually result in lower audio quality.
This should not be a problem if you are using a USB 2.0 connection.
