MACKIE M800 - Manual (Page 12)

POWER CORD
The M•800 is supplied with a detachable
power cord. Make sure the power switch is off
before firmly attaching the cord to the ampli-
fier. Fit the other end into an AC outlet
properly configured for the type of plug on the
power cord and for the voltage rating of the
amplifier.
For current-delivery purposes, the M•800’s
voltage source (wall outlet, extension cords, or
power strips) must be capable of continuously
delivering 12 amps (US model). And for safety
reasons, that source must be a “3-prong” outlet
with hot, neutral, and ground terminals. We’re
dealing with some big-time electricity here —
don’t mess with it. See “AC Power Consider-
ations” on page 18.
SPEAKER OUTPUTS
To use the binding post outputs, you can
terminate your speaker cables with single or
dual banana plugs, or bare wire.
To use banana plugs:
First pull off the small
plastic end caps from
each of the binding posts
to reveal the holes. It is
important to hand-
tighten each post before
plugging in the bananas.
To use bare wire:
Unscrew the amp’s bind-
ing posts, insert your
stripped wires (stripped
about 3/8" back) into the
side holes and retighten
the posts (finger tight is fine — do not use a
wrench!). Be careful that no wire strands
touch the chassis or other terminals.
The red posts are labeled “+,” which means
positive, and the black posts are labeled “–” for
negative. The amplifier is “common grounded,”
that is, both black posts are connected inter-
nally to ground.
Use high-quality speaker cable (16 gauge or
thicker) to connect the positive outputs of the
M•800 to the speaker’s positive inputs, and the
negative outputs to the speaker’s negative in-
puts. You probably know the importance of
getting these connections correct — if one
side is hooked up “out of phase,” this will cause
a reduction in the bass output and your pay.
If you’re using the M•800 in BRIDGE mode,
the speaker connects across the red posts only
(see page 16 for details).
In addition to the binding posts, the M•800
has 1/4" TS (tip-sleeve ) outputs, so you can use
speaker cables with 1/4" TS plugs. The tip is
positive (+) and the sleeve is negative (–).
They’re wired in parallel with the binding posts
and behave exactly the same (except they can’t
be used in
BRIDGE mode).
You can use both the 1/4" jacks and the
binding posts simultaneously. Just remember
that doing so creates two parallel loads.
Be Aware: Should you
choose to terminate your
speaker cables with 1/4"
TS plugs, make sure no-
body confuses these
cables with line-level
cables, (i.e., guitar cords). Guitar cords are
not designed to handle the high current out-
put of power amplifiers.
Furthermore, line-level inputs (like the sig-
nal input on a mixer) are not designed to
handle speaker-level voltages. The results are
not pretty, and can ruin a mixer technician’s
whole day.
