TOA P-912MK2 UL Single Channel Power Amplifier 120 Watts for paging & Music
The P-912MK2 Power Amplifier delivers up to 120 watts of output power. The power amplifier has an input port to accept one plug-in module.
THE TOA 900 SERIES are widely recognized as the industry standard in installed sound system amplification. When reliability and performance are critical – such as in paging and music distribution for airport, hospital, and industrial sound systems – you can count on the TOA 900 Series to perform consistently, day-in and day-out.
The TOA P-912MK2 Power Amplifiers deliver up to 120 watts of power respectively at less than 0.5% total harmonic distortion (THD) from 20 to 20,000 Hz (transformerless 4-ohm output). The power amplifiers have a high-impedance direct input and an input port (edge connector) to accept one plug-in module. Module selection is determined by application among the TOA plug-in modules.
The power amplifiers have a low-cut switch for a cutoff frequency of 60 Hz, and an input-level switch for input sensitivity of 1V (0 dBV) or 100mV (–20 dBV). Output terminals provide connections for 4-ohm and 8-ohm speakers, plus 25-volt and 70-volt speaker distribution outlets. With plug-in modules, the power amplifiers may be used as a PA amplifier.
