OPERATION

audio inputs

Automatic Turn-On Selection: The CX series offers two automatic turn-on modes; +12V and DC Offset.

•Remote Turn-On: Run 18 gauge wire from the Remote Turn-On Lead on your source unit to the terminal labeled REM between the ampliﬁ er’s positive and negative power terminals. This is the preferred automatic turn-on method.

•DC Offset Turn-On: The DC Offset mode detects a 6V DC offset from the HI-Level speaker outputs when the source unit has been turned on.

Input Level: The RCA inputs on KICKER CX 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: Use the XOVER switch on the end panel of the ampliﬁ er to set the internal crossover to OFF, HI or LO. When the switch is set to OFF, a full bandwidth signal will be ampliﬁ ed. Set the switch to HI if you want the ampliﬁ er’s internal crossover to serve as a high-pass ﬁ lter. 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/HI/LO” switch setting with the audio system on!

Crossover Control: The variable crossover on the front of the CX300.4 allows you to adjust the crossover frequency from 50–200Hz. The setting for this control is subjective; 80Hz is a good place to start.

Fader Switch: Depress the fader switch if you are running two sets of inputs (front and rear for example) to the ampliﬁ er. Leave the fader switch OFF if you want to drive all channels from a single stereo input.

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 Control: The variable bass boost control on the side of the CX300.4 ampliﬁ er is designed to give you increased output, 0–12dB, at 40Hz. 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.
