SPECIFICATIONS
POWER OUTPUT:
STEREO— 50 RMS watts continuous per chan-
nel into 4, 8, or 16 ohms both channels oper-
ating.
HARMONIC DISTORTION:
STEREO—Less than 0.25% at 50 watts output
from 20 Hz to 20 kHz both channels operating.
Typical performance is less than 0.1% at
rated power. Distortion decreases as output
power is reduced.
INTERMODULATION DISTORTION:
STEREO—Less than 0.25% if instantaneous
peak power output is 100 watts or less per
channel with both channels operating for any
combination of frequencies 20 Hz to 20 kHz.
FREQUENCY RANGE:
20 Hz to 29kHz +0, -0.1 dB at rated power.
15 Hz to 60 kHz +0, -0.5 dB at rated power.
10 Hz to 100 kHz +0, -3.0 dB at one-half of
rated power.
NOISE AND HUM:
90 dB or more below rated output.
OUTPUT IMPEDANCE:
STEREO—4, 8, and 16 ohms
OUTPUT VOLTAGES:
25 volts STEREO
DAMPING FACTOR:
14 at 4 ohms output
27 at 8 ohms output
13 at 16 ohms output
INPUT IMPEDANCE:
200,000 ohms
INPUT SENSITIVITY:
0.5 volt. Level control provided for higher in-
put voltage.
POWER REQUIREMENTS:
117 volts AC 50/60 Hz, 75 watts at zero signal
output.
250 watts at rated output.
SEMICONDUCTOR COMPLEMENT:
26 silicon transistors.
27 silicon rectifiers and diodes.
MECHANICAL SPECIFICATIONS:
SIZE: 5-7/16 inches high, 16 inches wide, 13
inches deep.
CHASSIS: Chrome and black.
WEIGHT: 38 pounds net, 53 pounds in shipping
carton.
SPECIAL FEATURES
The amplifier is completely stable when con-
nected to any loudspeaker system or even to
any reactive loads. The MC 2505 has special cir-
cuits to prevent damage by short circuit or open
circuit of the output loads, or by any amount of
output impedance mismatch.
Thermal cutouts are mounted on the output
transistor heat sinks to provide protection in the
event of inadequate ventilation.
