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 load 120 watts into 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 1.6dB Frequency Response +0, -0.25dB from 20Hz to 20,000Hz +0, -3dB from 10Hz to 100,000Hz Sensitivity 1 volt A-Weighted Signal To Noise Ratio 92dB (113dB below rated output) Intermodulation Distortion Maximum Intermodulation Distortion if instan- taneous 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 loadsInput Impedance 10,000 ohms Wide Band Damping Factor 100 at 4 ohms 200 at 8 ohms Power Requirements 100 Volts, 50/60Hz at 13.2 amps 110 Volts, 50/60Hz at 12.0 amps 120 Volts, 50/60Hz at 11.0 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 MC206 for the correct voltage.
