TOA-P-300D Power Amplifier

TOA-P-300D Power Amplifier

The P-75D, P-150D and P-300D are Toa professional 2-channel (stereo) power amplifiers, with nominal power outputs of 75 watts, 150 watts and 300 watts, respectively per channel with both channels driven into 8 ohms. Into 4 ohms they deliver 100 watts, 220 watts and 480 watts. In BTL (Bridged) mono use, the P- 75D, P-150D and P-300D deliver 200 watts, 440 watts and 960 watts of power into 8 ohms. All models have frequency response of +0dB, –0.5dB (20Hz to 20kHz), total harmonic distortion of less than 0.1% (at each nominal power outputs, 8 ohms, 20Hz to 20kHz). Each model offers many unique features such as, an octal socket for optional matching transformer to convert unbalanced input to balanced, magnetic circuit breaker, calibrated input attenuator, short circuit protection circuitry, 3-second turn-on delay, current limiter circuitry, protection indicator LED’s, signal presence indicator LED’s, peak indicator LED’s, ground terminal strip, high pass filter, mono/stereo mode switch, and true dual-mono configuration. Protection indicator LED’s are designed to actuate in cases of short circuit, D.C drift, turn-on delay and thermal warning. The signal presence indicator LED’s glow when more than -30dB signal level is fed to the inputs. For ease of maintenance and service, each channel of these amplifiers is built with modular, plug-in boards on a sub-chassis that can be quickly removed and replaced or repaired. All models are mechanically reinforced by a rugged front panel made of 3mm (1/8″) thick cast-aluminum and lined with another 3mm (1/8″) thick steel. With their overall sturdy construction, they are capable of withstanding even the roughest use on the road
