1.	Power LED (Top of unit - Not Shown) – This Blue LED illuminates when the unit is turned on.
2.	Thermal LED (Top of unit - Not Shown) – This Red LED illuminates if the amplifier internal components
3.	become too hot and engage the thermal protection.The amplifier will shut down to cool if this occurs.
	Protect LED (Top of unit - Not Sh wn) – ThisYellow LED illuminates if a short circuit or too low of an
4.	impedance is detected at the speaker connections.The amplifier will automatically shut down if this occurs.
	Cast Aluminum Heatsink – The cast aluminum heatsink of the Power amplifier dissipates heat generated by
5.	the amplifier's circuitry.
	SpeakerTerminals – The heavy duty, nickel-plated clamp wire connectors (+ and -) will accept wire sizes from
6.	8 AWG to 18 AWG.
	Remote Punch EQ (Optional Controller) – The Remote Punch EQ connection is made with a RJ-45 cable
	and can be installed in a variety of ways for easy control access.The control is used to boost low and/or high
	frequency information to overcome road noise.The remote overrides the Punch EQ on the amplifier when
	connected.
NOTE: Previous (prior to 2007) Punch Bass and Para-Punch remotes will not work with these amplifiers.
7.	Punch EQ – This control is a narrow band adjustment variable from 0dB to +18dB @ 45Hz with a Gyrator
8.	based Punch EQ that eliminates frequency shift with boost.
	Infrasonic Filter – A 28Hz High Pass filter designed to prevent frequencies below the audio range from being
	applied to the subwoofer from the amplifier. Consequently improving subwoofer performance and power
9.	handling, particularly in vented enclosures.
	Variable Cr	– Is a built-in 24dB/octave Butterworth filter with a crossover point variable from 35Hz to
10.	250Hz.The crossover is set to Low-Pass (LP).
	G in Control – The input gain control is preset to match the output of most source units. It can be adjusted to
11.	match output levels from a variety of source units.
	RCA Pass-Thru Jacks – This Pass-Thru provides a convenient source for daisy-chaining an additional amplifier
12.	without running an extra set of RCA cables from the front of the vehicle to the rear amplifier location.
	RCA Input Jacks – The industry standard RCA jacks provide an easy connection for signal level input.They are
13.	nickel-plated to resist the signal degradation caused by corrosion.
	REMTerminal – The heavy duty, nickel-plated captive c-clamp wire connector will accept wire sizes from
	12 AWG to 24 AWG.This terminal is used to remotely turn-on and turn-off the amplifier when +12V DC is
14.	applied.
	PowerTerminals – The power and ground are nickel-plated captive c-clamp wire connectors and will
	accommodate up to 4 AWG wire.
