TOA A-1800 Series  Mixing Amplifier

Features

Multi-purpose, multi-function mixer/power amplifiers specifically designed for maximum versatility and cost-effective high-performance are ideal units for any PA requirement in locations such as schools and offices and other intermediate size environments. A choice of different power outputs are offered as well as functions such as paging and dual zone coverage.

Versatility plus

The A-1800 Series amplifiers are distinctive for their input versatility. Each has three mic inputs, three auxiliary inputs, an emergency input as well as a telephone paging input. Paging can be initiated and the chime function can also be set to automatically output to two zones.

Phantom power provided

The A-1800 Series of amplifiers provide phantom power to all connected microphones. Phantom power can switched on or off as needed. The microphone inputs feature a balanced configuration with XLR connectors, allowing long cable runs without any problems.

Chime on input

The Mic 1 input incorporates chime on capability when the optional PM-660D Paging Microphone is used. Chime on can also be activated for the telephone paging. A selection of chime tones are available such as single, two-tone and four-tones which can either be in ascending or descending order.

2 Zone coverage

A-1800 Series amplifiers feature 2 speaker zones to which broadcasts can be sent independently or combined as desired. Emergency broadcasts will be heard in both zones. Even when the amplifier power is switched off, an emergency broadcast will be imitiated to both zones.
