COMBINING AMPLIFIERS

The Viper d2500.1 subwoofer amplifier

has the capability of connecting two or

more d2500.1 amplifiers in a

master/slave combination for increased

power with accurate level matching. It is

called the Parallel Synced Gain combina-

tion.

W W A A R R N N I I N N G G : : DO NOT attempt to combine amplifiers of different

power ratings. This amplifier combination works

correctly only if the Master and Slave amplifiers are

identical models.

Parallel Synced Gain

In this master/slave combination the

master amplifier pre-amp controls remain

active and the slave amplifier pre-amp is

bypassed. This allows the master ampli-

fier to control gain, filter, and sub-level

on all amplifiers.

This combination allows the amplifiers to

drive their own separate subwoofer(s)

while being synced together via an in-

phase audio pre-amp signal from the

master amplifier. Wiring connections to

the amplifier subwoofer outputs in this

combination should be standard in-phase

configurations, creating a parallel

speaker connection. (Refer to Parallel

Synced Gain section of this guide for

amplifier and speaker connection

diagrams.)

N N O O T T E E : :

One master amplifier can control up to three slave

amplifiers in this combination. Multiple identical

master/slave combinations can be added to any

given system.

Combined Amplifiers Gain

and Filter Settings

Set the Subsonic, EQ, and other filter

settings on the master amplifier to the

positions that achieve the best sound

quality. Adjustment guidelines are

discussed in the Crossover and Gain

Adjustment section of this guide.
