ATLAS SOUND PA702, 2-CHANNEL 70W POWER AMPLIFIER

 

Switch 2 - Sense AC / Audio

, when Switch 1 is in the “

DOWN

” position you may select the type of remote 

turn on 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 “

DOWN

” 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 PA702. See AC Sense control below for sensitivity 
adjustments. 

 

Audio Trigger 

- This switch function is used if you have an external audio source plugged into either the RCA 

or Balanced inputs and you want that audio to turn on or activate the amplifier. If Switch 2 is in the “

UP

” 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 PA702. See Audio Sense control below for sensitivity adjustments. 

 

Switch 3

 - Input Mono / Stereo Switch, this switch affects both the RCA and Balanced inputs. When this switch 

is in the “

UP

” position, only one input signal is needed to feed signal to both amplifier channels using the same 

signal.  Note: the input sensitivity is reduced by 6dB in the "

MONO

" mode. When this switch is in the "

DOWN

position, both input are separated and operate as "Stereo" mode.

 

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.

8.  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 PA702 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 PA702 level controls have no 
affect on this feature.

9.  AC 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 “

DOWN

” or “

AC

” position. By rotating the potentiometer clockwise 

(right) the trigger point becomes less sensitive to turn on, meaning it will take more AC Current draw from the 
Unswitched AC outlet to turn on the amp. Note: When using the AC Sense mode between “

STANDBY OR 

SLEEP

” and “

ON

” is instantaneous as long as the AC Sense is set properly and the component plugged into the 

AC Unswitched socket is on drawing current.
