Wire gauge

For music applications, where one amplifier is powering one more speaker, use a minimum of 16-gauge wire. For Monday night football bar installations, make the wire gauge as large as possible between speakers.

Low level audio wire runs

Low-level audio needs only 22 gauge twisted pair with shield. Beldon 9451 or equivalent is a popular choice. Being differential, the low level input can be as long as 3500 feet without concern. If the source is unbalanced, a balancing preamplifier is recommended for longer runs over 200 ft.

Powering secondary speakers without amplifiers in paging only applications

For paging applications, voice only, very minimal current is needed therefore 18 gauge in most cases up to 250 ft will be sufficient.

Amplifier Protection

The amplifier is protected from shorts, over heating and will shut itself down until the heat or short is removed. To avoid heat issues, an extra large heat sink is featured on the amplifier.

Loud music installations, dance floors etc.

Provide power at every speaker. Turn their volumes all the way up controlling level at a central location. If a subwoofer is used, crossover at 180 Hz and provide signal the module from 180 Hz and up. A CD output on each channel will power up to 5 power modules. After that, a preamplifier will be needed.

In most cases, particularly if a subwoofer is used, 12.5 watts per speaker will provide excellent sound and that will allow each module to power one more speaker.
