In addition to the binding posts, the M•1400 has Speakon® connectors for connecting the speakers to the amplifier. 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 con- nection) 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 posi-

tive 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, mean-

ing 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. Observe the motion of the speaker cone. 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).
