PERFORMANCE LIMITS
PERFORMANCE
Mclntosh audio power ratings are in accordance
with the Federal Trade Commission Regulation of
November 4, 1974 concerning power output claims
for amplifiers used in home entertainment products.
POWER OUTPUT
70 watts minimum sine wave continuous
average power output, per channel,
both channels operating into 8 ohms
load impedance which is:
23.7 volts RMS across 8 ohms
40 watts minimum sine wave continuous
average power output, per channel,
both channels operating into 16 ohms
load impedance which is:
25.3 volts RMS across 16 ohms
OUTPUT LOAD IMPEDANCE
8 ohms or 16 ohms
RATED POWER BAND

TOTAL HARMONIC DISTORTION
0.2% maximum harmonic distortion at
any power level from 250 milliwatts to
rated power per channel from 20 Hz to
20,000 Hz, both channels operating
INTERMODULATION DISTORTION
0.2% if instantaneous peak power output is twice
rated continuous average power or less per channel
with both channels operating for any combination of
frequencies 20 Hz to 20,000 Hz
FREQUENCY RESPONSE
