Connections - Quest Engineering PR Series Owner's Manual

PR-120 / PR-240

Connections

INPUT: Connect microphones or balanced line-level sources to mixer-amplifier balanced inputs.
Set Gain volume accordingly. Connect unbalanced line-level signals to RCA input connectors.
OUTPUT: Maintain proper polarity on output connectors.
For each output channel, connect the output EURO block terminals to the loudspeaker Ioads.
Use terminals marked
to and COM for constand-voltage loudspeaker loads.

Connect the COM terminal to speaker negative(-) lead; connect one of the other terminals to
speaker positive (+) lead.
The impedance and output voltage are same as following Table.
PR-120
PR-240
NOTE : Impedances indicated in the table represent the total speaker system impedances.
Figure shows the way how to select impedance.
The wires of output transformer are connected to terminal on output select pcb same as follow
table.
