Speciall
Features:
The MC 250
is completely stable when connected to any loudspeaker system or even to
reactive loads. The MC 250 has special circuits to prevent damage by short
circuit or oen circuit of the output loads, or by any amount of output imedance
mismatch. Therminal cutouts are mounted on the output transistor heaat sinks to
provide protection against inadequate ventilation.

Power
Output:
50 watts RMS
continuous power per channel, both channels operating into a 4 Ω, 8 Ω or 16 Ω
load
100 watts
RMS monophonic
Total
Harmonic Distortion: less than 0,25% at
rated power output fromm 20 to 20,000 Hz . Distortion typically measures less
than 0,1% and decreases as output power is reduced.
Intermodulation
Distortion: less than 0,25% for any
combinations 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
Frequency
Range: at rated output, both channels
operating +0, -0,25 dB 20 through 20,000 Hz. At reduced output, both channels
operating +0, -3 dB 5 through 70,000 Hz
Output
Impedance: output taps are provided for
4 Ω, 8 Ω and 16 Ω loads. Full rated power output is provided at each output
tap. The 16 Ω output will provided 25 volts RMS for constant voltage multiple
speaker distribution lines. Monophonic Output taps are provided for 2, 4 and 8
Ω. 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 Ω ;
38 at 8 Ω, and 16,6 at 16 Ω
Input
Sensitivity/Impedance: 0,5 volt will
produce rated power output; a gain control for each channel allows independent
adjustment of amplification in each channel. Input impedance is 200,000 Ω
Hum and
