MC 250 ELECTRICAL SPECIFICATIONS

POWER OUTPUT: 50 watts RMS continuous power per channel, both
both channels operating into a 4 ohm, 8 ohm or 16 ohm load.
100 watts RMS monophonic.

HARMONIC DISTORTION: Less than 0.25% at rated power output.
from 20 to 20,000 Hz. Distortion typically measures less than
0.1% and decreases as output power is reduced.

INTERMODULATION DISTORTION: Less than 025% for any come
binations of frequencies between 20 and 20,000 Hz at 100 peak
watts output per channel or at any level less than 100 peak watts

per channel. Your McIntosh MC 250 can be pro-

Output taps are provided for 2, 4 and 8 ohms. Full rated power
output is provided at each output tap. These taps are also available
on the octal socket, left center of control panel.

OUTPUT DAMPING FACTOR: Greater than 15 at 4 ohms, 38 at
8 ohms, and 16.6 at 16 ohms.

INPUT SENSITIVITY AND IMPEDANCE: 0.5 volt WI produce rated ' .

CONTROLS: MONO-STEREO Switch, LEFT GAIN. RIGHT GAIN.

SPECIAL FEATURES: The MC 250 is completely stable when con-
nected to any loudspeaker svstem or even to reactive loads. The
MC 250 has special circuits to prevent damage by short circuit or
open circuit of the output loads, or by any amount of output im-
pedance mismatch. Thermal cutouts are mounted on the output
transistor heat sinks to provide protection against inadequate
ventilation.
