2.

RCA Input Channels 1 through 4 - accepts RCA input from a head unit, pream-
plifier, or equalizer. These inputs are configured by the Input Mode switch posi-
tion (refer to item 11 below).

3.

RCA Line Output - provides easy connection to additional amplifiers.

4.

Gain Control - continuous adjustment for full power output. The upper control
is for channels 1/2 and the lower control is for channels 3/4.

5.

Intelli-Bass - continuously adjusts from 0 to 12dB of boost centered at 45Hz.

6.

Remote Bass Input - connects optional HP-RB1 remote bass control to control
the bass level from the driver’s seat. The HP-RB1 is only active when the crossover
switch (lower switch) for channels 3/4 is at the LPF setting.

7.

LPF (Low-Pass Frequency Control) - adjusts the frequency (50Hz–500Hz) of the
upper crossover frequency. When set for this position the optional remote bass
control is active (upper channels 1/2, lower channels 3/4).

8.

X-Over (cross-over) - activates LPF (low pass crossover), FLAT (all pass), or HPF
(high pass crossover) (upper channels 1/2, lower channels 3/4).

9.

HPF (High-Pass Frequency Control) - adjusts the frequency (50Hz–500Hz) of the
lower crossover frequency (upper channels 1/2, lower channels 3/4).

10. Power LED - when illuminated (green) indicates that the amplifier is on.

Protect LED - when illuminated (red) indicates that the amplifier protective cir-
cuitry has been activated due to thermal, output short, supply undervoltage or
supply overvoltage.

11. Input Mode - 1/2 channel or 3/4 channel selectable. In the 1/2 CH position, the

input to channels 1 and 2 are also supplied to channels 3 and 4, respectively. In the
3/4 CH position all 4 channels are supplied separately When the switch is to the
left (4 CH position), front and rear inputs are independent. This allows a source
unit with an internal fader to fade between the 1/2 CH and 3/4 CH outputs.

HP4600 Connections

1.

ATC Fuse - (2) 20-amp ATC fuses protect the amplifier against internal electrical
damage 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-
tem battery.

WARNING:

Always protect this power wire by installing a fuse or circuit breaker of the
appropriate size within 12 inches of the battery terminal connection.

3.

REM - this terminal turns on the amplifier when (+) 12 volt is applied. Connect it
to the remote turn on lead of the head unit or signal source. If a (+) 12 volt remote
turn lead is not available, a Remote Power Adapter (P/N #55000) can be used to
