5. Bridge Mode

The term BRIDGE is used when two independent

amplifier channels are used to drive the same load. The

load is in series (a bridge) between the two amplifier

channels.

Channel A is used as the "dominant" channel and its

output is in phase with the input signal, and channel

B has to have its phase reversed so it is exactly 180

out of phase with the input signal.

As two amplifiers with a phase difference of 180

now driving the load you will now have double the

voltage into the load. This means you will now have four

times the power into that load. The output can now be

considered as an active balanced output.

A common use of an amplifier in BRIDGE mode is for

driving 70 volt & 100 volt distribution lines. In BRIDGE

mode, The AM1600 can produce in excess of 114 volts

into a line impedance of 8 ohms (1600 watts) and in

excess of 90 volts into a line impedance of 4 ohms

(2100 watts).

Equally the units can be used in bridge mode to provide

the correct voltage/power requirements for an applica-

ble load.

As shown in Figure 6, there are four steps in setting up

your AM1600 amplifier for running it in BRIDGE mode.

Whilst the amplifier is off,

1. Connect the signal source to the Channel-A female

input XLR.

2. Loop from Channel-A male XLR to Channel-B fe-

male input XLR with a Reverse Phase Lead.

A reverse Phase Lead is wired:

Pin-1 to

Pin-2 to

Pin-3 to

3. Connect your load between the red binding post

are

output terminals, where the positive side of the

load is connected to the Channel-A output and the

negative side of the load goes to the Channel-B

output . There are no further connections required.

4. Turn the attenuators on both channels fully clock-

wise (0dB - no attenuation).

You can also source the output from the Channel-A

SPEAKON output connector where Channel-A will be

on the pin marked 1+ and Channel-B will be on the pin

marked 2+.

NOTE: You should check after market manufactured

Speakon interconnecting speaker leads before

connecting them to your amplifier. Some leads are

manufactured for specific purposes, or specific use,

and may have pins shorted inside the connector. Any

speakon lead with shorted pins will obviously short the

output of your amplifier (either to ground, or output to

output - be careful).
