CONFIGURING THE PA-2© IN YOUR SYSTEM

Your purchase of the

LINEAR POWER™ PA-2

is a major step towards creating

the ultimate audiophile system for your vehicle. Before installing your new

PA-2

the preamp must be properly configured for your system. The

PA-2

configuration is changed by moving 'shunts' inside the preamp chassis like those
used for computers. Remove the top cover of the preamp and locate the 'shunts'
near the RCA jacks and above the "LP" logo on the circuit board.

The

PA-2

is shipped from the factory configured for two audio source input with

front/rear fader control patched internally. The sample system shown in

Figure

allows front/rear fader control without affecting the main output level sent to

your subwoofer amplifier. The signal from the main output is sent to the fader
control in this configuration. See

Figure 1B

for the internal shunt settings.

For systems using an external crossover such as the

LINEAR POWER™ X0-2

(

Figure 2a

), the

PA-2

can be configured for externally patched fader capability

to prevent the subwoofer level from being affected by the front/rear fader control.
The signal from the second input on the

PA-2

is sent to the fader control in this

configuration. See

Figure 2b

for the internal shunt settings.

For the maximum in-dash control and optimum sound quality in your system, the

PA-2

can be used with the

LINEAR POWER™ X0-3

crossover. Patch the

signal from the main output on the

PA-2

to the

X0-3

crossover, (

Figure 3a

and use the three level controls on the

X0-3

mounted in-dash to balance the

signal levels in your system. The fader circuitry is completely disconnected from
the audio path in this system to prevent any circuit loading from the unused fader
control that may affect sound quality. See

Figure 3b

for the internal shunt

settings.
