Finally, an
infrared receiver and transmitter
for remote control of the DAP is
positioned on the left side of the main display. Owners of learning remote
controls such as those provided with Proceed preamplifiers may transmit
infrared control codes from the DAP to their learning remotes to “teach” the
remote how to control the DAP. Subsequently, the IR receiver in the main
display will respond to the learning remote’s commands for input selection,
volume control, and certain other commands. (See
Remote Control of the
DAP
for more information.)

UP/DOWN BUTTONS
These
up/down buttons
are used to make adjustments on the DAP, includ-
ing source and volume selection. While the
up/down buttons
normally se-
lect the digital input (1 through 5) to be processed, they may also be used
to control the output level of the DAP. (See
mode button
, below.)

MODE BUTTON
Pressing this button toggles the DAP between input selection and volume
selection modes.
Ordinarily, the DAP should be used at its maximum output level, with vol-
ume control provided by a high quality active preamplifier which follows
the DAP in the signal path. This approach provides the best sonic perfor-
mance as well as improved user convenience.
However, if for some reason a high quality active preamplifier is not avail-
able, pressing the
mode button
will cause the DAP to change into its vari-
able output mode of operation, wherein the
up/down buttons
are used to
control the output level of the processor. Pressing the
mode button
a sec-
ond time will return the DAP’s
up/down buttons
to their normal input se-
lection function.
5
MUTE
Pressing the
mute
button will reduce the main output level of the digital
audio processor by approximately 20 dB. Pressing the
mute
button a sec-
ond time will return the DAP to its previous output level. This function is
available at all times, whether the DAP is in input select or variable output
mode.
If you have the DAP in its variable output mode of operation and adjust the
volume with either the front panel buttons or a remote control while in the
mute mode, the digital audio processor will adjust its volume
from the
muted volume
and
disengage
the mute function. By so doing, the DAP
avoids sudden, unexpected changes in volume.
