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 internally 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 nobody confuses these cables with line-level

cables, (i.e., guitar cords). Guitar cords are not designed to handle the high current output of power amplifiers.

Furthermore, line-level inputs (like the signal 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.
