FRONT PANEL CONNECTIONS/CONTROLS

NOTE: The step numbers listed below are referenced on the Input Wiring Diagram.

1.RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 4 volts.

2.Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the ampli- fier to the output level of the signal source.

3.Crossover Frequency Adjustment - Adjusts the crossover point for the on-board active crossovers.

4.Crossover Selection Switch - Controls the type of filter for the on- board active crossover. FLAT does not attenuate any frequencies and is for full-range speaker systems. HPF attenuates low frequencies and is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofers speakers.

5.Bass EQ Switch - Adds an additional 6 or 12 db of bass boost to the speaker output (4600X 12 db only).

6.Status LED - Will light BLUE to indi- cate the amplifier is on and oper- ating normally, and will be RED if the amplifier shuts down due to short circuit, or overheating detected by on-board protection circuitry.

NOTE:	The 2300X and 4600X amplifiers require that
	the system remote power be cycled off and on
	again to restart the amplifier after a protection
	shutdown.
	The 1500X amplifier will cycle off and automati-
	cally turn back on when the fault condition clears.
	The amplifier should be inspected for proper venti-
	lation clearance on all sides of the amplifier (2-
	inches). The speaker wiring should be inspected
	for any shorts.
NOTE:	The 1500X and 2300X amplifiers have one
	combined Power/Protection (BLUE/RED) LED,
	the 4600X amplifier has separate Power (BLUE)
	and Protection (RED) LEDs.
