four Position dip switch Assignment
switch 1 - sense on/off
AC trigger. When the switch is in the "doWn" position, all trigger circuits are bypassed. The only way to turn the
amp On or Off is via the mains AC Power Switch located on the front panel. When in the "uP" position either the
Audio or AC Sense turn on Triggers is activated. See switch 2 for selection.
switch 2 - sense Ac / Audio
trigger. Note the AC Mains Power Switch must also be in the "on" position.
Ac trigger
- This switch function is used if you have an external device is plugged into the Unswitched AC outlet
and you want that device to turn on or activate the amplifier. The "uP" position of Switch 2 is for AC trigger, meaning
if a device such as a projector is plugged into the Unswitched AC outlet and is turned on the AC trigger circuitry
will sense current draw and turn on the PA1001G. Note: To trigger the AC sense circuity you need a minimum of a
100mA of current draw to activate the PA1001G.
Audio trigger
Balanced inputs and you want that audio to turn on or activate the amplifier. If Switch 2 is in the "doWn" position it
is in Audio Sense mode. When audio is present at either the RCA or Balanced inputs, the trigger circuitry will turn on
the PA1001G. See Audio Sense control below for sensitivity adjustments.
switch 3
– Line Out Pre - Post VCA - This switch function works in conjunction with the Line Out Jack and the
Remote Level Control feature. This switch determines if the Line Out signal is fixed (Pre) or works with the Remote
Level Control (Post). The "doWn" position is Pre Remote Level, meaning the Remote Level does not affect the
signal of the Line output and the "uP" position is Post or after the Remote Level Control, meaning the level will
change with the Remote Level Control.
switch 4
– Hi Pass Filter In / Out, when this switch is in the "uP" position no input filter is applied. With the switch
in the "doWn" position a 100Hz 12db Hi-Pass filter is engaged at the input of each channel.

Audio sense trigger Adjustment
This potentiometer works when Dip Switch 1 is set to "doWn" or "sense on" position and Dip Switch 2 is in the
"uP" or "Audio" position. By rotating the potentiometer clockwise (right) the trigger point becomes less sensitive to
turn on, meaning it will take more audio signal at the input to turn on the amp. Note: Once the PA1001G has sensed
audio signal and has triggered on, it will take15 -20 min for it revert back into sleep mode even when there is no
audio present. The PA1001G level controls have no affect on this feature.
10. line level out
This unbalanced RCA output allows you to feed the audio signal from the PA1001G amplifier to another amplifier.
You can select to have a fixed signal or you can assign it to work with the Remoter Level Control. See Line Out
Function Switch for settings.
11. remote level control VcA
Remote location of the level control can be accomplished via the VCA control port. Connect the two leads from
the optional remote volume control to these terminals. Set the system's maximum levels using the amplifier level
controls and then use the remote VCA potentiometer as an attenuator from the maximum levels set.
