Dimensions Front Panel: 17-1/2 inches (44.5cm) wide, 5-3/8 inches (13.7cm) high. Depth behind front mounting panel is 15 inches (38.1cm) including clearance for connectors. Panel clearance required in front of mounting panel is 3/4 inch (1.9cm). Note: When a CD Disc is inserted or ejected, the panel clearance required in front of mounting panel is 3-3/4 inches (9.5cm). Weight 21 pounds (9.5kg) net, 35 pounds (15.9kg) in shipping carton NOTES 1. The heavy notes 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 recommended by the manufacturer.
