TOA P 150 D Stereo Amplifier


Standard 19" equipment rack


2 channel


220W continuous power per channel driving 4 Ohm loads


Frequency Response: +0dB, -0.5dB, 20Hz to 20kHz


Total Harmonic Distortion: Less than 0.01% at 220W, 4-ohm, 1kHz


Intermodulation Distortion: 0.05% using frequencies of 60Hz and 7kHz, mixed in a ratio of 4:1, at power output of 100 watts into 8-ohm


Input Sensitivity: An input of +4dB (1.23V), 0.5dB, produces an output of 220 Watts into 4-ohm. INPUT ATTENUTOR set for maximum level


Input Impedance: 10k-ohm (unbalanced)


Damping Factor: Greater than 260 at any frequency from 20Hz to 1kHz Greater than 95 at any frequency from 20Hz to 20kHz


Impedance Actual Output Less than 0.03 ohms at any frequency from 20Hz to 1kHz Less than 0.08 ohms at any frequency from 20Hz to 20kHz


Hum and Noise: 109dB below rated output (20Hz - 20kHz), 114dB below rated output (Il-IF-A weighted)


Rise Time: 10 microseconds, or better (10% -90% of I volt at 1kHz square wave output)


Slew Rate: 10 volts per microsecond, or better (at 100 watts into 8- ohm, 200kHz square wave input)


Channel Separation: At least 90dB at 1kHz, At least 75dB at 20kHz


Phase Shift: 20Hz to 20kHz, 15 degrees


Offset Voltage: Less than 10mV DC


Input Connectors (per channel): One "male' and one 'female" XLR connector in parallel, 2 (:01(1, pin 3 "hot", and pin 1 "shield". XLR's are unbalanced and in parallel with two tip-sleeve (standard) phone jack.


Output Connectors (per channel): Standard 3/4-inch spacing, "5-way" binding posts, Ground Terminal Strip, 2 lug terminal block with removal shorting strap Indicators


A pair of green LED's for signal presence,


A pair of red LED's for output clipping,


A pair of red LED's for circuit protection and thermal warning, A green LED for power ON


Controls: Input Attenuators 22-position, log-linear', detented and dB-calibrated input attenuators (one per channel) attenuates input signal in 2dB steps from 0dB attenuation to -34dB, then steps of


-37dB, -42(IB, -50dB, infinity.


Circuit Breaker AC Switch


High Pass Filter Switches (IN OUT)


-1 2dB per octave at 15Hz


Accessory Switches (IN/OUT) Bypass for octal socket, Mode Switch - Switchable for st ('I' mode operation


Overall Protection: AC line is protected by circuit breaker. Protection LED's flashes when heat sink temperature reaches more than 105C. Protection l,l'D's turn on when the protection relay activates in such cases that DC currant is fed to output, and that short-circuit occurs.


A beast of an amp - old school Mosfet


Great for driving heavy loads like power hungry sonus faber.


Looks old but works very well

Keen pm me
