Input Level: The RCA inputs on KICKER ZX amplifi ers are capable of receiving either Hi or Low-level signals from your source unit. If the only output available from your source unit is a Hi-Level signal, simply press in the Input Level switch on the amplifi er. Refer to the wiring section of this manual for additional instructions.

Crossover Switch (ZX300.1): Use the XOVER switch on the end panel of the amplifi er to set the internal crossover to OFF or LO. When the switch is set to OFF, a full bandwidth signal will be amplifi ed. Set the switch to LO if you want the amplifi er’s internal crossover to serve as a low-pass fi lter. Never change the crossover “OFF/LO” switch setting with the audio system on!

Crossover Control (ZX400.1, ZX500.1, ZX750.1): The variable crossover on the top of the amplifi er allows you to adjust the crossover frequency from 50–200Hz. The setting for this control is subjective; 80Hz is a good place to start.

Input Gain Control: The input gain control is not a volume control. It matches the output of the source unit to the input level of the amplifi er. Turn the source unit up to about 3/4 volume (if the source unit goes to 30, turn it to 25). Next, slowly turn (clockwise) the gain on the amplifi er up until you can hear audible distortion, then turn it down a little.

Bass Boost Switch (ZX300.1): Turn the bass boost on to increase bass by 12db at 40 Hz. If you enable the bass boost, it may be necessary to reduce the input gain control on the amplifi er to avoid clipping.

Bass Boost Control (ZX400.1, ZX500.1, ZX750.1): The variable bass boost control on the top of the amplifi er is designed to give you increased output, 0–18dB, at 40 Hz. The setting for this control is subjective. If you turn it up, you must readjust the input gain control to avoid clipping the amplifi er.

Remote Bass-ZXRC (not included with ZX300.1, ZX400.1, ZX500.1): When the crossover on your amplifi er is set to LO pass, you have the ability to control the output level of the amplifi er remotely. To mount the ZXRC remote bass level control, simply screw the metal bracket to the chosen location, then slide the housing onto the bracket until it snaps into place. Run the cable from the controller to the “Remote Bass” jack on the amplifi er chassis.
