speaker load, the more heat is generated. For low- impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable.

10.Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts;) soldering the termi- nals after crimping is also recommended.

11.Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can’t deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach

its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system.

FIGURE 1—AMPLIFIER CONNECTIONS/CONTROLS—FRONT (PA200.4)

FRONT PANEL CONNECTIONS/CONTROLS

1. RCA Input Jacks—Accepts line level outputs from

head units or signal processors at voltages between

250mV and 7.5 volts. (The PA500.4 and PA1100.5

also have a Rear Input.)

2. RCA Line Output Jacks—Thesepass-through

RCA jacks can be used to send the input signal

to a second amplifier.

3. Line Out Switch (PA1100.5)—three positions:

sum L/R—left front and rear and right front and

rear channels are summed.

sub L+R—set the switch to this position when

using an additional PA600.1 amplifier connected

in Parallel mode.

sub 180—set the switch to this position when

using an additional PA600.1 amplifier connected

in External Bridge mode.

8. X-Over Selection Switch (HPF, Flat, LPF)—

The HPF attenuates low frequencies and is used

with mid-range speakers and tweeters. Flat does

not attenuate any frequencies and is for full range

speaker systems. LPF attenuates high frequencies

and is used for subwoofers.

9. X-OverFrequency—adjusts the crossover point

(50-500Hz) for the on-board active crossover

(PA500.4 and PA1100.5).

10. Remote—Optional accessory which allows the level

to be adjusted remotely (usually located for control

by the vehicle’s driver). (PA500.4 and PA1100.5)

11. LPF Control(PA1100.5)—Sets high frequency limit

of subwoofer channel.

12. LED/FAN—Allows connection of an optional LED

light bar or optional cooling fan for the amplifier.

13. Status LED—Will illuminate GREEN to indicate the

REMOTE (PA500.4/PA1100.5)

Remote—Controls the subwoofer amplifier gain, from a remote location for ease of adjustment during listening.

4. Gain Control—Controls the amplifier’s sensitivity

and is used to match the input level of the amplifier

to the output level of the signal source (front and

rear on PA500.4 and PA1100.5).

5. Subsonic Switch—The OFF position takes the filter

out of the system, the IN position places the filter into

the system (PA1100.5).

6. Sub Gain— Subwoofer channel gain adjustment.

7. Bass EQ Switch—Adds 8dB additional bass boost

(PA200.4 and PA500.4). Allows 8db additional bass

boost on the sub channel (PA1100.5).

amplifier is on and operating normally, and will be

illuminated RED if the amplifier shuts down due to

short circuit, DC offset, or overheating detected by

onboard protection circuitry.

14. Sub Input/Line Out—selects RCA jacks (4) (Sub/

Line Out) as either Subwoofer Input or Line Output

(PA1100.5).

15. Input Mode Switch—Selects 2 or 4 channel

operation (PA200.4 and PA500.4).
