Sense Trigger for more detailed information (page 9).
4. RCA Input
Unbalanced signals are accepted when using the Left and Right RCA connectors. Note:On the bottom of the
chassis there are level controls for the for the Left and Right RCA inputs. This allows you to adjust the level
from OFF to +6dB. Factory settings calibrated for 320mv of input sensitivity. See Mixer Function page 9 for use.
5. Balanced Input Connections
Left and Right balanced input signals can be accomplished by wiring the removable Phoenix type connector
per the labeling on the rear of the amp. Note: The middle pin is the common ground connection for both Left
and Right input ground. For unbalanced signals connect the (–) and (GND) pins together.
6. Speaker Connections
A removable Phoenix type connector is supplied to connect your speakers to the PA702. It is recommended
to use 16guage wire or higher for connection to the speaker. Note: Do not overload the amp by connecting to
many speakers to the amp. Four ohms per channel is the maximum load.
