TOA MEETING AMPLIFIERS
Compact and lightweight portable amplifiers with built-in speakers for voice reinforcement and low-level music playback for small meetings. Options are available to incorporate a cassette player into the unit to make an all-in-one solution. Power is AC or internal batteries.
Built in a tough, moulded, ABS case, the front of the amplifier presents a clean appearance, with a speaker grille, a horn tweeter aperture and LED indicators which show power status. A handle hinges up from a recessed area where there is a power switch, LEDS which mimic the display on the front panel and volume controls for the microphone input.
On a sloping rear panel are the microphone input (2-pole 6.35mm jack), an input tone control, Aux output connector (2-pole 6.35mm jack), and Aux input which has dual RCA (phono) connectors, mixing a stereo input such as a cd player to mono. To the left of this is a blank space, used in the WA-1822C for the cassette mechanism. Below this is the battery compartment, taking eight ‘D’ cells in a removable cartridge, and a cover which opens to reveal storage for up to three microphones, an internal speaker on/off switch, screw-terminals for external speaker, IEC mains inlet.

This model is supplied with a record/replay cassette mechanism ready fitted, but is otherwise as the WA-1822. The deck has it’s own volume control, and features variable-speed auto-reverse and dual direction operation. It also has a function to detect periods of silence in the recorded material while fast winding or rewinding and then pause, waiting for the operator to initiate the next replay. Continuous play may be selected. Battery life is reduced.
