DPX1851 and DPX11551 stackable configurations

In this mode, the master amp's front-panel controls apply to all amplifiers.
For example, setting the crossover frequency on the master sets it on all slaves. This
works for all front-panel controls.
Multiple amplifiers can be daisy-chained together. For example, if you had six
DPX1851s in a show car, you could control all of them from one master unit (and
one remote).
The following describes the configuration of the amplifiers:
Master
First slave
Additional slave(s) • Set the master/slave switch to Slave.
Each amplifier can independently control separate speaker loads (assuming the
phase switch on all amplifiers is set the same).
Or, to power a large single load (phase switch opposite on the amplifier), you can
bridge across the amplifiers: + and + to load, - and - to each other. The master amp
is "speaker +" for in-phase operation.
Any pair of amplifiers could also be bridged, but be careful to set the phase switches
correctly.

Setting the gain

After completing the installation, follow these steps to set the gain control and per-
form the final system checks.
1. Turn the gain control all the way down (counterclockwise).
2. Select the proper input voltage range using the IVS. See "Selecting Input Voltage"
in the "Operations" section of this manual.
3. Turn the vehicle's ignition switch on.
4. Turn the audio system on with the volume turned all the way down.
5. Set all tone or equalization controls to flat positions and turn loudness off.
6. Play a CD and turn the volume up on the head unit until you hear distortion. This
should be most of the way up.

• Route input from the head into the normal mode inputs.
• Set the master/slave switch to Master.
• Route a single RCA cable from the Slave Out to first slave unit.
• Set the master/slave switch to Slave.
• Route a single RCA cable from the master Slave Out to the
current amplifier's Slave In.
• Route a single RCA cable from the previous amplifier's Slave
Out to the current amplifier's Slave In.
