Stereo; Mono; Bridged - Mackie M-2600 Owner's Manual

STEREO

mode (separate left and right
inputs, separate left and right outputs) is the
typical setup for amplifying stereo signals.

MONO

mode (sometimes called Dual-
Mono — one or two inputs, two mono outputs)
is for sending a mono signal to two different
speaker sets, with separately-adjustable GAIN
controls.

BRIDGED

mode (sometimes called
Bridged-Mono — one or two inputs, one mono
output) uses both sides of the amp to send
great power to one speaker.
BRIDGED
In STEREO mode, the M•2600 Power
Amplifier can deliver 1300 watts per side into
2 ohms. If that's not enough, you can use two
M•2600's, each in BRIDGED mode, and deliver
2600 watts per amplifier into 4 ohms. Or, you
can use one amp in BRIDGED mode to power a
monaural system. Finally, BRIDGED mode is
also popular for subwoofer applications — but
please see LOW OUT (SUBWOOFER) on page
28 for a special subwoofer surprise.
To use all the M•2600's power to drive one
speaker using BRIDGED mode:
1. Turn off the power to the M•2600.
2. Set the AMP MODE switch to BRIDGED.
3. The BRIDGED mode requires the speaker
to be wired as follows :
120 VAC 60 Hz
2000 WATTS
26
Connect the positive side of the speaker
cable to the Channel 1 red (+) binding post.
Connect the negative side of the speaker
cable to the Channel 2 red (+) binding post.
4. Instead of the binding posts, you could use
the MONO BRIDGE Speakon connector.
Pin 1+ connects to your speaker red post
(positive +).
Pin 1– connects to your speaker black post
(negative –).
5. In MONO or BRIDGED mode, you can use
either Channel 1 input, or Channel 2, or
both. If both inputs are used, the inputs are
summed.
Once again: Before making connections to
an amp or reconfiguring an amp's routing, turn
the power off, make the changes, then turn the
power back on.
In BRIDGED mode, both
connections to your
speaker are live; that is,
neither is grounded
through the chassis. Take
great care to read and fol-
low all of the safety instructions. The amplifier
is capable of up to 116 VAC across the speaker
terminals, potentially LETHAL!
