No sound?
If you have your input source and speakers connected, and you can’t get music to play, check the following:
1. Verify that the power cord is plugged in and that the outlet is powered up.
2. Check the front panel and make sure that the display lights up.
3. If the display is on and the DAC is locked onto a signal, increase the volume to a significant level to
ensure the level is high enough for music playback.
4. If you can hear the slight turn on and off noise when the DAC is activated, but there still isn’t any
sound, make sure you are getting a signal to it.
5. Verify that the input is selecting the proper input for what you have connected, and is displaying a
sample rate.
6. If the input is in the proper position and still no sound, then try replacing the interconnects to verify the
connection between the DAC and source.
7. Verifiy that the interconnects are conducting by replacing them on a different set from a connection that
you know works.
8. Now that you have interconnects that you know work, try connecting the DAC to another source that
you know has worked in the past.
If you are still experiencing problems after checking all possibilities and using the resources provided please
contact your dealer or Wyred 4 Sound directly for further assistance.
Because the DAC-1 is really an 8ch DAC inside, make sure that all sources (where applicable, ie: DVD players,
cable/satellite boxes) are programmed in their setup menu to output 2ch PCM or stereo digital signals. In some
cases, the DAC will actually try to decode multichannel formats, but will be unsuccessful because the DACs
outputs are tied together internally. If the DAC is playing music, then there is nothing to worry about, but if you
get loud switching noises, or no sound at all, this is probably why.

Is there too much hum or hiss coming out of your speakers? If you put your ear right next to the tweeter
of your speaker, you should barely be able to hear any hiss in normal conditions, depending on amps. If the
noise is easily heard at a distance, try putting your source on mute, or pause. If this eliminates the noise, it’s
inherent in the source. If the noise is still there when the preamplifier is muted, try disconnecting the inputs to
the amplifier. If the noise is still there when the inputs are disconnected, and the inputs are shorted with shorting
plugs, then your amplifier may need some servicing. If the noise is not there when the inputs are disconnected,
try putting a cheater plug (ground isolator) on one or all components in order to eliminate a ground loop issue.
NOTE: We only recommend using a ground isolator for trouble shooting purposes, and should be removed after
the problem has been found. Having the ground of any unit disconnected can potentially create a dangerous
situation.
