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. [. . . ] 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. If you're still not sure, here is a simple test: take a 1. 5V flashlight battery and connect the positive terminal of the battery to the positive (+) input of the speaker, and connect the negative terminal of the battery to the negative (­) input of the speaker. It should move out when voltage is applied, and return to rest when voltage is removed. Make sure all the speakers in the system move in the same direction (there are a few exceptions -- some speakers are deliberately designed with reverse-polarity woofers). 1+ 1­ 1+ COLD 1­ 2+ 2­ HOT Speakon Connectors CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT AVIS: RISQUE DE CHOC ELECTRIQUE -- NE PAS OUVRIR EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. REFER SERVICING TO QUALIFIED PERSONNEL. SERIA INPUT The M·1400/M·1400i amplifier gives you a choice -- it has the traditional XLR inputs, as well as 1/4" TRS (tip-ring-sleeve) input jacks. Sonically (and electrically) they're identical, so choose either one. Since these two inputs jacks are in parare in parallel (the THRU allel with the inputs as well), you shouldn't connect more than one source to the SIGNAL INPUT jacks. Each can be used with either balanced or unbalanced signals.

The M·1400/M·1400i amp expects to see a nominal signal level anywhere between the ­10dBV "semipro" and +4 dBu "pro" standards, meaning almost any line-level mixer or other device can be plugged into the amp's INPUTs. controls to adjust the gain of Use the GAIN the amplifier to match the signal level you're using.

Simply plug the signal source outputs into the first amp's INPUTs , patch from that amp's THRU jacks to the next amp's INPUTs, and so on, daisy-chaining as many amps as you can afford (assuming your console has low-impedance outputs). A general rule of thumb is to maintain a load impedance 10 times or more than the source impedance to prevent excessive loading. If your console has an output impedance of 100 ohms, then you can daisy-chain up to twenty M·1400/ M·1400i amplifiers, which presents a load of 1000 ohms to the console (input impedance of 20 kohms divided by 20 amplifiers = 1000 ohms). The THRU jacks can also be used to relay the signal on to other devices such as a DAT or cassette recorder, enabling you to record exactly what the audience is hearing. The THRU jacks are wired straight from the XLR and TRS INPUTs -- there is no electronic circuitry between -- so the signal going into the amp is exactly the same as the signal coming out of the THRU jacks.
