Unless otherwise noted, all voltages indicated on the schematics are measured under the following conditions: a. AC input at rated voltage marked on rear panel. b. All voltages are +/-10% with respect to ground. A high impedance (10 megaohm) voltmeter must be used.2.Unlessotherwisespecified: a. Resistor values are in ohms. b. Capacitor values are microfarads (uF). c. Inductor values are in microhenries (uH)3. On PC board drawings, Square pad indicates: a. Polarized Capacitors - Positive b. Diodes - Cathode c. Others - Pin 14. WARNING Parts marked with the symbol have critical characteristics. Use only replacement parts recom- mended by the manufacturer.NOTESPERFORMANCE SPECIFICATIONSSpecifications Power OutputMinimum sine wave continuous average power output per channel, all channels
