Power Sources -- This Mackie product should be connected to a power supply only of the type described in these operation instructions or as marked on this Mackie product. [. . . ] For current-delivery 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 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 Considerations" on page 25 for more details. The red posts are labeled "+, " which means positive. The black posts are labeled "­" for negative. You probably know the importance of getting these terms correct -- if one side is hooked up "in phase" and the other side is "out of phase, " you'll be "out of work. " (By the way, although everyone says "phase" in this situation, the correct word is "polarity". . . but it's not as much fun to say. ) Using high-quality stranded speaker cable (16 gauge or thicker), connect the positive outputs of the M·1400/M·1400i to the positive inputs of your speakers, and the negative outputs to the negative inputs. The exception: If you're using the M·1400/M·1400i in BRIDGE mode, this does not apply, (see BRIDGE on page 22). In addition to the binding posts, the M·1400i also has 1/4" TS (tip-sleeve) SPEAKER OUTPUTS, so you can use speaker cables with 1/4" TS plugs. The tip is positive (+) and the shield is negative (­). They're wired in parallel with the binding posts and behave exactly the same (except they can't be mode). used in BRIDGE G N D Bare Wire 1/4" Spade Lug 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). 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.

These are locking connectors that are easy to attach and are designed to handle high power levels into low-impedance loads. These connectors have become popular with many loudspeaker manufacturers because they provide a quick, yet safe and secure method of connecting speaker cables. Speakon connectors have a twist-locking mechanism that prevents them from being pulled out accidentally. Pin 1+ is positive (+) and Pin 1­ is negative (­). Before making connections to an amp or reconfiguring an amp's signal routing, turn the amp's GAIN controls down, turn the POWER off, make the changes, turn the POWER back on, and then turn the GAIN controls back up. Although the M·1400 amplifier can handle "opens" (no connection) and "shorts" (positive and negative signal lines in direct contact), you don't want the speaker ends of live cables to zap every piece of equipment they touch as they're being dragged across the stage. Ordinarily, applying a positive voltage to a speaker's positive input and negative voltage to the negative input results in an outward excursion of the woofer. But some woofers are built with reverse polarity, meaning that the above conditions result in an inward excursion. If you're not sure which type of speakers you have, take a look at their literature. [. . . ] · Make sure the signal cable is not routed near AC cables, power transformers, or other EMI-inducing device. · Is there a light dimmer or other SCR-based device on the same AC circuit as the monitor?Use an AC line filter or plug the amplifier into a different AC circuit. · If possible, listen to the signal source with headphones plugged into the console.
