Unless otherwise noted, all voltages indicated on theschematics are measured under the following conditions:a. AC input at 120 volts, 50/60Hz.b. All voltages are +/-10% with respect to ground. A high impedance (10 megaohm) voltmeter must be used.3. Unless otherwise specified:a. Resistor values are in ohms.b. Capacitor values are microfarads (uF).c. Inductor values are in microhenries (uH).4.On PC board drawings, Square pad indicates:a. Polarized Capacitors - Positiveb. Diodes - Cathodec. Others - Pin 15.WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.NOTESPower OutputMinimum sine wave continuous average power output perchannel, all channels operating is: 200 watts into 4 ohm or8 ohm loadRated Power Band20Hz to 20,000HzTotal Harmonic DistortionMaximum Total Harmonic Distortion at any power level from250 milliwatts to rated power output is: 0.005% for 4 or 8ohm loadsDynamic Headroom1.7dBFrequency Response+0, -0.25dB from 20Hz to 20,000Hz+0, -3dB from 10Hz to 100,000HzSensitivity1.0 Volt Unbalanced with a 4 ohm Loudspeaker2.0 Volt Balanced with a 4 ohm Loudspeaker1.4 Volt Unbalanced with a 8 ohm Loudspeaker2.8 Volt Balanced with a 8 ohm LoudspeakerA-Weighted Signal To Noise Ratio89dB (112dB below rated output)Intermodulation DistortionMaximum Intermodulation Distortion if instantaneous peakoutput per channel does not exceed twice the rated output, forany combination of frequencies from 20Hz to 20,000Hz, withall channels operating is: 0.005% for 4 or 8 ohm loadsInput Impedance20,000 ohms Balanced10,000 ohms UnbalancedWide Band Damping FactorGreater than 60 at 4 ohmsGreater than 140 at 8 ohmsPower Requirements100 Volts, 50/60Hz at 1440 watts110 Volts, 50/60Hz at 13.0 amps120 Volts, 50/60Hz at 12.0 amps220 Volts, 50/60Hz at 6.0 amps230 Volts, 50/60Hz at 6.0 amps240 Volts, 50/60Hz at 6.0 ampsNote: Refer to the rear panel of the MC207 for the correct voltage.DimensionsFront Panel: 17-1/2 inches (44.45cm) wide, 9-7/16 inches(23.97cm) high.
