TOA MIXER AMPLIFIERS - A-2000 Series
The TOA A-2000 series mixer amplifiers were designed for use as part of commercial audio systems in schools, offices, shops, restaurants, houses of worship and large meeting rooms, where voice or background music is required. Designed with a steel plate casing and ABS resin front panel, they operate on either AC by using the attached power cord, or 24V DC by using the relevant connections on the rear-mounted M4 screw terminals. The A-2000 series utilises a -60dB 600ohm 5-pin DIN type input that is electronically balanced for input one and -60dB 600ohm balanced microphone inputs on 6.3mm jack for inputs two and three.
21V DC phantom power can be applied to channel one, and mute switching can be applied by shorting pin four and pin five of the 5-pin DIN connection. The mute function reduces the volume of all other inputs up to 30dB by setting the rear-mounted, rotary, mute adjust control. Bass and treble tone controls, set at +/-10dB at 100Hz and +/-10dB at 10kHz, help to attain the most preferred sound output. Visual LED indicators include power, signal, and peak. As well as catering for 100V, 70V, and 4 ohm outputs, the TOA A-Series amplifiers all include L/R unbalanced RCA phono (600ohm) as record outputs.
