Peachtree preDAC Manual page 19

The connected streaming device
(including the Bluesound NODE 2i)
makes popping sounds or other audio
bursts when the sample rate changes in
a playlist.
If there is a random loss of audio,
accompanied by a click sound inside the
preDAC and switching sources restores
audio.
If something is connected to the USB-A port that does not support audio (Apple
Watch Magnetic Charger for example), the red standby LED will flash in sequence: 5
quick flashes, pause, 5 quick flashes, pause...until it is disconnected. Note that while
connected, 5V is provided to the device. For example, the Apple Watch Magnetic
Charger will still charge the Apple Watch if it is attached.
most frequently in low humidity
environments and rooms with carpets.
If the unit is behaving erratically
afterwards, power it down completely
by turning off the rear panel AC
switch, letting it sit for a minute or so,
then powering it back on. If the issue
persists, please contact your reseller
or Peachtree Audio.
Hold down the desired digital audio
input button on the front panel (COAX,
OPT-1, or OPT-2) when bringing the
unit out of standby. Whichever button
is being held down, that's input's
dropout prevention option will toggle
between ON and OFF.
The standby LED will flash a certain
number of times to indicate that input's
current state:
6 flashes for OFF; used for most
players and TV sets.
7 flashes for ON; used for Bluesound
and others. (Use this mode if the
attached streaming device has noise
during sample rate changes).
NOTE: it will show the state for
the button that was held down, not
necessarily the current input
(eg. if you were last on COAX input,
but held down the OPT-1 button
coming out standby, the flashing will
show the state for the OPT-1, even
though the current input is COAX).
To disable the "power failure mute"
feature (firmware version 1.9 and
above), press and hold the volume
control knob in for ~15 seconds, until
the standby LED blinks 5 times.
This is useful in some instances where
electrical interference on the AC Mains
causes random unexpected loss of
audio. Pressing and holding the knob
in for ~15 seconds again reverts to the
factory default mode (4 blinks).
Note that disabling the "power
failure mute" can cause noise in the
speakers if AC mains power suddenly
is removed (when a power failure
occurs for example). You can find the
