High-End SQ Monoblock Amplifier McIntosh MC443M w/ Meter JDM First 500 EDITION Muluus
High-End SQ Monoblock Amplifier McIntosh MC443M with Meter JDM First 500 EDITION kondisi muluus......
Specs:
• 1 X 300W RMS into 4 ohms
• 1 x 500w RMS into 2 ohms
• High output current with 1Ω stability
• Power Guard® clipping protection
• Ultra-low distortion less than 0.005% distortion.
Power Guard®, a patented McIntosh circuit design, eliminates harsh clipping distortion
without sonic side effects. Not a “soft clipping” circuit or limiter, Power
Guard has no effect prior to clipping. A waveform comparator monitors the output
signal and compares it to the input signal. Should distortion appear, Power
Guard acts by reducing the gain until the distortion is reduced to below clipping.
Then, the amplifier returns to full gain.
Illuminated output level meter-
These meters are extremely accurate, responding to 95% of full scale with only one cycle of a 1,000Hz tone
burst. The meter circuitry includes a logarithmic converter, which provides readings
computed in watts, as well as time stretching to assure full indication of peak
power demands. The meter scales are calibrated for both normal and bridged
channel operation.
