Connections
The HF-63X1/X2 has barrier strip screw terminals that accept up to #10 AWG (5.3mm2) stranded loudspeaker wire.
INPUT Terminals
Connect the amplifier’s full range output signal to the HF-63X1 or HF-63X2 INPUT terminals. Observe proper polarity; the amplifier’s + signal to the HF-63X1 or HF-63X2 + INPUT, the amplifier’s - signal to the HF-63X1 or HF-63X2 - INPUT. Use the largest wire size and shortest wire length for the application.
HF OUT Terminals
The HF OUT terminals are factory-connected to the compression driver. These terminals should ONLY be connected to the HF-63X1 or HF-63X2 compression driver. Observe proper polarity; the + HF OUT signal to the compression driver’s + input, the - HF OUT signal to the compression driver’s - input.
LF OUT Terminals
The HF-63X1 is designed specifically for use with QSC’s LF-3115 low frequency loudspeaker and the HF-63X2 for the LF-3215 loudspeaker. The LF OUT terminals are factory-terminated to lead wires with spade-lugs. These should ONLY be connected to QSC’s model LF-3115 or model LF- 3215 low frequency loudspeaker. Observe proper polarity; connect the + LF OUT signal to the low frequency loudspeaker’s + input, the - LF OUT signal to the low frequency loudspeaker’s - input.
