PS Audio PCA-2 - Manual (Page 5)

Front Panel Controls
The PCA-2 front panel includes a volume knob
and the following five buttons:
1. Power
2. Input Down
3. Input Up
4. Loop
5. Mute
Power On/Off
The Power Button activates the front panel dis-
play, engages the volume control and routes the
input signal to the appropriate output(s). The PS
logo will also illuminate blue.
Pressing the Power Button again will put the
PCA-2 in a standby mode. It will consume very
little power and not pass any signal to the ampli-
fier. The display and the logo will not illuminate.
For optimum performance keep the PCA-2
attached to a live outlet.
Input Up/Down
The Input Up/Down buttons cycle though
all inputs. The front panel will display the
number of the present input as well as
the input name. This name can be
specified by the user (see Setup
Menu).
Loop
The Loop function will acti-
vate the Loop output. Loop
Output is a fixed level
output, which is not
affected by the vol-
ume control. LOOP
will illuminate in the
front panel display
when it is active.
The Loop function
is useful in conjunc-
tion with recording
devices or equaliza-
tion equipment.
Mute
Pressing the Mute button will silence the output
of the PCA-2. If Mute is activated, the number
of the current input will still be displayed while
the display will read MUTE. To exit the mute
status, press mute again or simply adjust the vol-
ume control.
By default the PCA-2 will not produce any signal
when in mute, however the mute volume level
can be specified by the user (see Setup Menu).
Volume Knob
Adjusting the Volume Knob will increase or
decrease the output volume. When the volume
is adjusted it will numerically display the volume
level in the display window. After 3 seconds the
display will return to the input name. By default
the volume level is displayed in a 0 to 100 scale.
A decibel reference level scale from -90dB to
+10dB can also be used (see Setup Menu).
