PERFORMANCE SPECIFICATIONS 2 1. The heavy lines on the schematic denote the primary signal path. 2. Unless otherwise noted, all voltages indicated on the schematics 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 - Positive b. Diodes - Cathode c. Others - Pin 1 5.WARNING Parts marked with the symbol have critical characteristics. Use only replacement parts recom- mended by the manufacturer. NOTES Power Output Minimum sine wave continuous average power output per channel, all channels operating is: 200 watts into 4 ohm or 8 ohm load Rated Power Band 20Hz to 20,000Hz Total Harmonic Distortion Maximum Total Harmonic Distortion at any power level from 250 milliwatts to rated power output is: 0.005% for 4 or 8 ohm loads Dynamic Headroom 1.7dB Frequency Response +0, -0.25dB from 20Hz to 20,000Hz +0, -3dB from 10Hz to 100,000Hz Sensitivity 1.0 Volt Unbalanced with a 4 ohm Loudspeaker 2.0 Volt Balanced with a 4 ohm Loudspeaker 1.4 Volt Unbalanced with a 8 ohm Loudspeaker 2.8 Volt Balanced with a 8 ohm Loudspeaker A-Weighted Signal To Noise Ratio 89dB (112dB below rated output)Intermodulation Distortion Maximum Intermodulation Distortion if instantaneous peak output per channel does not exceed twice the rated output, for any combination of frequencies from 20Hz to 20,000Hz, with all channels operating is: 0.005% for 4 or 8 ohm loads Input Impedance 20,000 ohms Balanced 10,000 ohms Unbalanced Wide Band Damping Factor Greater than 60 at 4 ohms Greater than 140 at 8 ohms Power Requirements 100 Volts, 50/60Hz at 1440 watts 110 Volts, 50/60Hz at 13.0 amps 120 Volts, 50/60Hz at 12.0 amps 220 Volts, 50/60Hz at 6.0 amps 230 Volts, 50/60Hz at 6.0 amps 240 Volts, 50/60Hz at 6.0 amps Note: Refer to the rear panel of the MC207 for the correct voltage.
