Combining amplifiers – Directed Electronics 64601910 d2500.1 User Manual

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.

WAARRNNIINNGG:: 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.)

NNOOTTEE::

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.
