TOA P-912MK2 UL is a power amplifier that delivers up to 120 watts of output power. It has one input port that can accept any input module except 1-01, and one direct input. The input sensitivity is switchable between 100 mV and 1000 mV, and the input impedance is 10 kΩ. The outputs are transformer main (8Ω, 25 and 70 volts, balanced) and direct main (4Ω, unbalanced). The output regulation is less than 0.5 dB (no load to full load) for the direct main output, and less than 1.0 dB (no load to full load) for the transformer main output.
