TROUBLESHOOTING

ISSUE SOLUTIONS
Check that the power switch on the
back panel is on. If it is, the on/standby
LED on the front panel LED should
be lit red. Check that the AC outlet is
functioning correctly by plugging in
a lamp or other device to confirm its
operation.
Check that the preDAC is not muted
(blinking input LED) or headphones
connected to the front panel (preamp
outputs muted). Be sure your power
amplifier and input source are powered
on and playing at a reasonable volume
level. Disengage the loop function to
see if that resolves the issue. Double-
check the connections on the rear
panel. Ensure any attached power
amplifier(s) are switched on
Check the remote control batteries by
removing the cover on the back try-
ing new ones. Make sure the remote
control has a clear "line of sight" to the
sensor on the front panel. Check that
no powerful light sources, like direct
sunlight, is interfering with the sensor
on the front panel.
Try re-launching the music application
(iTunes, etc.). If the computer doesn't
recognize the preDAC, unplug the
USB cable from the computer and
the preDAC, wait a few seconds,
then reconnect the USB cable. Try
re-starting the computer. The preDAC
is designed to remain locked on USB
signals at all times, but computers
drop connections occasionally and
require prompts to re-connect.
If you have music files available
on a laptop computer, play them
while running the computer on
its battery power only. If the hum/
noise disappears, then the ground
connection on the computer's AC
adapter is introducing a "ground loop"
into the system. This is not unusual,
but the USB input on the preDAC is
designed to minimize the potential. If
the issue persists, please contact your
reseller or Peachtree Audio.
Sometimes static buildup on your
hand will discharge into the unit when
touched and cause an audible click or
pop noise. This is normal and happens
