ATLAS SOUND PA702,
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
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
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.
