60W 5ch 100/70V mixer amp

This rackmountable mixer amplifier delivers 60 watts across five channels for constant-voltage distributed audio. It targets installers who need background music and paging across large facilities such as restaurants and hotels. The unit accepts two XLR, three quarter-inch and four RCA input pairs for flexible source connectivity. Separate bass and treble controls let you tailor the sound to each space.

Replaces multiple amp and mixer boxes

A single 118803 unit combines mixing, amplification and constant-voltage distribution that would otherwise require separate components. The jump is worth it when you must drive hundreds of speakers over long cable runs without heavy gauge wire or complex impedance math. It is not for installations that need more than five input zones or higher per-channel wattage than 60 watts.

Standard rackmount install with priority mic

The chassis mounts in a standard equipment rack and weighs 20.16 units for stable placement. Wiring is simplified because every speaker on a channel connects in parallel using simple wattage addition. The dedicated EMC killswitch mutes all inputs except microphone one for emergency announcements. Miswiring the 100 or 70 volt taps is the most common error that causes distortion or speaker damage.

Questions about this item

What rack spacing does the 118803 need to mount?

It is a rackmountable audio control center designed to fit standard equipment racks for distributed sound installations in large facilities and restaurants.

Which input connections must be wired first during installation?

Connect the 2 XLR, 3 quarter-inch, and 4 RCA pair inputs to the 5-channel mixer, then set the dedicated EMC emergency killswitch so only Mic 1 remains active for announcements.

What ongoing upkeep does the 118803 require?

Periodically verify the step-up and step-down transformers in the 100/70V constant-voltage lines and check that the total speaker wattage on each channel stays within the 60W amplifier rating.
