HF INPUT Terminals
The HF-63 has barrier strip screw terminals that accept up to #10 AWG (5.3mm
2
) stranded loudspeaker wire. Connect the amplifier’s
high frequency output signal to the loudspeaker’s HF INPUT terminals. Observe proper polarity; amplifier’s + signal to loudspeaker +
HF INPUT, amplifier’s - signal to loudspeaker - HF INPUT. Use the largest wire size and shortest wire length for the application.
NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance.
Do not apply full range signal to the HF-63! There is no crossover in the HF-63, only an equalization and protection
network. All required signal processing must be done before the signal is applied to the HF-63.
HF OUTPUT Terminals
The HF OUTPUT terminals are factory-connected to the compression driver. These terminals should ONLY be connected to the HF-63’s
compression driver.

Note: The HF-63 connection enclosure
does not contain a crossover network!
Ensure only high frequency signal is
applied to HF INPUT terminals or com-
pression driver damage will occur.
