Determine which
AMP MODE
is best
for your application:
•
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 mode — one or two inputs, two mono
outputs) is for sending a mono signal to
two different speaker sets, with separately-
adjustable level controls.
•
BRIDGED
mode (sometimes called
Bridged-Mono — one or two inputs, one
mono output) uses both sides of the amp to
triple the power going to one speaker. An
M•2600 in
BRIDGED
mode, delivers 2600
watts (into 4 ohms). Garsh!
Note:
In
BRIDGED
mode, 4 ohms is the mini-
mum speaker impedance you should connect to
the amplifier. If you connect a lower impedance
load, the amplifier may go into
PROTECT
mode and the
SHORT
LEDs will turn on.
Then the audience will turn on you.
6.
In
STEREO
mode, connect line-level cables
from your signal source to the M•2600’s
INPUT
jacks, either XLR or TRS:
• The XLR and TRS inputs for each
channel are wired in parallel.
• The balanced XLR inputs are wired
pin 2 = hot (+), pin 3 = cold (–), and
pin 1 = shield (ground).
• The 1/4" TRS inputs are wired
tip = hot (+), ring = cold (–), and
sleeve = shield (ground), and can accept
either balanced (TRS) or unbalanced (TS)
cables.

INSTALLATION
You can mount the M•2600
amp in any standard rack
system (see page 29), or
place it horizontally on a
floor or table. The heavier
internal components are
located towards the front of the chassis to make
it easier to hold the amp by its front handles.
The M•2600 amp draws its
ventilation air in from the
front and out through the
side panels. It needs plenty
of fresh air to stay cool.
DO NOT BLOCK THE VENTILATION PORTS
(see page 29).
CONNECTIONS AND SETTINGS
1.
The output terminals
are capable of high voltage
output, so for your safety,
the
POWER
switch
must be off before making
any connections.
2.
Turn the
GAIN
controls fully down
(counterclockwise) for now.
3.
Set both
LOW CUT FILTER
controls to
their
TYPICAL
marks (35Hz).
4.
Set the
LIMITER
switch on.
Note:
If you’re using the M•2600 to power a
subwoofer, you probably do not need an external
crossover. Please see page 28 for details.
