END PANEL LAYOUTS
1. RCA Input - accepts RCA input from a head unit, preamplifier, or equalizer.
2. RCA Line Output - provides easy connection to additional amplifiers.
3. Master/Slave Switch - controls whether the amplifier is a slave or master when
connected in combined amplifier configurations. (Refer to the Line Output
Configurations section of this guide.)
4. Gain Control - continuous adjustment for full power output.
5. Infrasonic Switch - when On cuts off extremely low bass frequencies (below the
range of human hearing, that speakers cannot effectively reproduce). Improves
efficiency of the amplifier’s power supply, improves sound reproductive perform-
ance, and reduces chances of damaging the subwoofers.
6. Intelli-Bass - adjusts the bass for up to 18dB of boost equalization.
7. LPF - this filter attenuates high frequencies and sets the high frequency limit of
the subwoofer channel (adjustable from 30 to 250 Hz).
8. Remote Bass Jack - connects optional HP-RB1 remote bass control to control the
bass level from the driver’s seat.
9. Phase Control Switch - provides either 0 or 180 degree phase shift of the ampli-
fied output (speaker) with respect to the input signal to facilitate bridging of
amplifiers.
10. Power LED - when illuminated (green) indicates that the amplifier is on.
11. Protect LED - when illuminated (red) indicates that the amplifier protective
cirucitry has been activated due to thermal, output short, supply undervoltage or
supply overvoltage.
1. 1 ATC Fuse - this 40A fuse protects the amplifier against internal electrical dam-
age and is meant to protect the amplifier only. All other power connections
should be fused at the source.
2. +BAT - connect this terminal through a FUSE or CIRCUIT BREAKER to the positive
terminal of the vehicle battery or the positive terminal of an isolated audio sys-
SPEAKER
