Power Amplifiers

solid state amplifier, unused in over 20 years, very nice condition, tech checked 11/16 50 watts per channel minimum RMS (both channels operating) at 8 ohms from 1 Hz to 20 kHz with less than .25% total harmonic distortion. Typically less than .02% at rated power in midband. Approximate actual power available per channel at "clipping" (both ch. op.): 80 (4 ohms), 60 (8 ohms), 35 (16 ohms) Power bandwidth Frequency response 0.05 Hz to 100 Khz (-3 db) Input sensitivity 1.1 Volts RMS for rated power and load. Input impedance 30 Kohms (nominal). Output taps Output regulation Overall negative feedback Damping factor More than 500 at rated power and load (20 Hz to 20 kHz). (Effective internal impedance approximately .012 ohms.) Distortion Intermodulation distortion: Less than .1% at rated output (56.56 V p to p) and load (SMPTE method). THD and IMD both decrease with decreasing output. Slew rate Rise time Hum & noise Wide-band, unweighted, more than 90 dB below 50 watts at 8 ohms - power line components (hum) more than 80 dB below 50 watts at 8 ohms. Power supply energy storage Power requirements 105-120/210-240 VAC, 50/60 Hz, 600 watts maximum. 120 watts at idle. 300 watts at rated power.

The pure analog input stage preserves all the detail and nuance of the most delicate passages. The Class D output stage with switching power supply results in impressive output combined with cool-running efficiency. Learn More

The Audioaccess MA-362 12-Channel Amplifier represents a high-value approach while providing 12 channels of clean amplifier power for multiroom system applications. Power to Spare: With a power rating of 50 watts per channel at 8 ohms from 20Hz to 20kHz with less than .05% THD, the MA-362 will drive virtually any loudspeaker to room-filling volume. Power into 4 ohms is even more impressive at 75 watts per channel. All channel pairs may be bridged if additional power is required. Cool operation is ensured with a design incorporating heatsinks, flow-through ventilation and low-noise fans. Learn More
