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.

WARNING: 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 amplifier 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.)

NOTE:

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.
