If you shut down your
system, turn off your ampli-
fiers first. When powering up, turn on your amplifiers last. This way, equipment
feeding the amp won’t “pop” or “thud” when it’s powered up or down.
POWER CORD
We all know what a power cord is. The M•1400/M•1400i has a big beefy cord built in. Plug the power cord into an outlet that is capable of delivering the correct voltage for your model.
For
purposes, the M•1400/
M•1400i’s voltage source (wall outlet, extension cords, or power strips)
must be capable of continuously delivering 15 amps (for 120V versions). And for safety rea- sons, that source must be a
SPEAKER OUTPUTS
Some call them “GR” jacks, others call them “Banana” jacks, but we prefer to call them “Binding Posts.” You can call them whatever you like (except late for supper). These terminals are your standard fare.
To use the binding post outputs, you can terminate your speaker cables with single or double banana plugs, spade lugs, or leave them unterminated: Unscrew the amp’s binding posts enough to reveal the holes on their sides, then insert your stripped wires (stripped about 3/8" back) into the holes and retighten the posts (finger tight is fine — please don’t reef on them with a wrench!). Be careful that no runaway strands touch the chassis or other terminals.
The red posts are labeled “+,” which means positive. The black posts are labeled

In addition to the binding posts, the M•1400i also has 1/4" TS
TS plugs. The tip is positive (+) and the shield is negative
