A&E Specifications Summary
The mixer power amplifier operates on AC mains or 24 V DC. It supports and mixes 3 balanced microphone inputs (one 5-pin DIN type and two phone jack inputs) and 2 unbalanced AUX inputs (RCA pin jacks). Speaker outputs are available as balanced (floating) high impedance (100V/70V) and low impedance (4Ω). A low impedance REC out is also provided. Performance criteria include a power output of 240 W at less than 1% THD (at 1 kHz, 1/3 rated power), a frequency response of 50 Hz to 20 kHz (±3 dB), and an S/N ratio exceeding 60 dB. Phantom power (DC +21 V) and muting functionality (0-30 dB attenuation for other inputs via MIC 1) are included. Tone controls for bass and treble offer ±10 dB adjustment at 100 Hz and 10 kHz, respectively. The unit features power, signal, and peak indicators, along with fan cooling. The panel is made of black ABS resin, and the case is black steel plate. The mixer power amplifier is identified as TOA model A-2240.
