ARC Audio 4000se マニュアルとユーザーマニュアル
MASTER/SLAVE
The 4000se is equipped with a MASTER/SLAVE circuit. This allows you to control 2 or more amplifiers from one set of controls. All of your gains,
crossovers, bass boost, subsonic filter and remote level will be controlled from a single "master" amplifier. This eliminates all the tedious gain and
crossover matching normally needed when using multiple amplifiers.

Bridging
Bridging is a way to combine the power of 2 channels into 1. When you wire the amp bridged you have a higher voltage differential between +
and -. That means MORE POWER. If you have 2 identical, properly designed mono amplifiers (They can not be a stereo amp that is bridged
internally) you can bridge them together to create 1 channel.
Warning
When bridging any amp or amps, each channel sees half the ohm load. 4 ohms bridged is the same as 2 ohms stereo. 1 ohm bridged is equal to 1/2 ohm
stereo. Check the compatibility of you woofers and amplifier before you begin.
2 - 4000se amplifiers in a bridged configuration must not be connected to a load lower then 2 ohms.
For bridging to work both amplifiers must be playing exactly the same signal at exactly the same output level. To make this easier use the
"MASTER" and "SLAVE" as above but the slave amp must be set to "Out of PHASE"
Use the configuration below.
