Features and Benefits
HIGH OUTPUT-CURRENT
Greater than 50 amperes peak output current to
drive uneven speaker loads. Some poor speaker designs
have input impedances that dip to 1 or 2 ohms at
various frequencies. The MC7150 has the output current
reserve to drive them.
OVER 58 JOULES OF ENERGY STORAGE
Huge main filter capacitors that guarantee an
excellent signal to noise ratio and the energy storage
necessary for the wide dynamic range that "Digital
Audio" demands.
GOLD PLATED OUTPUT TERMINALS
Mclntosh gold plated output terminals will deliver
full output power to all speakers.
ILLUMINATED PEAK RESPONDING OUTPUT WATT-
METERS
The Mclntosh MC7150 is the first high fidelity
power amplifier to have Output Wattmeters that respond
95% full scale to a single cycle tone burst at 2kHz.
Voltage and current output are electronically measured,
multiplied and fed to a special circuit that accelerates
the pointer movement in the upward direction. When
the pointer reaches its peak it pauses only long enough
for the human eye to perceive its position, then drops.
It is almost 10 times faster than a professional VU
meter.
WATTS HOLD
The "Watts Hold" mode for the output meters,
records and displays the highest power output peak of
the source material being amplified.
ULTRA LOW DISTORTION
Distortion so low that it defies measurement,
even with the finest distortion analyzers. At mid-freq-
uencies, 8 ohm load, the distortion meter reads the
residual distortion of the oscillator (.0002%) with or
without the MC7150 in the circuit. This means the
amplifier distortion is lower than the analyzer is capable
of measuring.
WIDE POWER BANDWIDTH
Full power output capability well above and below
the frequencies that can be heard by humans.
POWER GUARD
The exclusive Mclntosh circuit that prevents
harsh sounding clipping and protects your speakers from
damage.
