FEATURES AND BENEFITS
HIGH OUTPUT CURRENT
Greater than 85 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 MC7300 has the
output current reserve to drive them.
OVER 227 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.
50 AMP GOLD PLATED OUTPUT TERMINALS
An exclusive Mclntosh gold plated output
terminal that will deliver full output power to speaker
wires from 16GA to 4GA. 4 gauge wire is .204
inches in diameter, nearly 1/4 of an inch. ("Monster
Cable" is 8GA, .128 inches in dial. You can connect
directly to the wire. Special lugs or pins that can
cause power loss are not required.
ILLUMINATED PEAK RESPONDING OUTPUT
WATTMETERS
The Mclntosh MC7300 is the first high 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.
