“Break-in” Period
Your new DAC will deliver outstanding performance brand new. However, over the course of playing it for the first
200 hours or so, the DAC will go through a “break-in” period as it reaches its ultimate sonic potential. This is a normal
phenomenon of high-end audio equipment and the before/after differences are readily audible. If you are hearing
bright, tight, light or dimensionally flat characteristics, those are symptoms of a product that is not quite broken in
yet. Patience will reward you! After the break-in period, your unit will be ready to perform as soon as it’s powered
on. If you have any questions on your DAC’s performance, contact your dealer or Wyred 4 Sound directly.
Troubleshooting
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.
Verify 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.
Note: Because the DAC-2v2 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 DAC’s
outputs are tied together internally. If you hear loud switching noises, or no sound at all, this may be why.
Got Hum?
Is there 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 amp 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 troubleshooting purposes, and should be removed after the problem has been found. Having the
ground of any unit disconnected can potentially create a dangerous situation.
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.
