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. Ahigh 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 recommended by the manufacturer.NOTESGeneral SpecificationsPower Requirements100 Volts, 50/60Hz at 120 watts110 Volts, 50/60Hz at 120 watts120 Volts, 50/60Hz at 120 watts220 Volts, 50/60Hz at 120 watts230 Volts, 50/60Hz at 120 watts240 Volts, 50/60Hz at 120 wattsNote: Refer to the rear panel of the C1000 Controller for thecorrect voltage.Frequency Response+0, -0.5dB from 10Hz to 20,000HzTotal Harmonic Distortion0.08% from 20Hz to 20,000HzSignal To Noise RatioHigh Level, 93dBPhono, 80dBMaximum Voltage Output8V RMS Unbalanced, 16V RMS BalancedOutput Impedance220 ohmsSensitivityHigh Level, 450mV for 2.5V rated outputPhono MM, 4.5mV for 2.5V rated outputPhono MC, 0.45mV for 2.5V rated outputInput ImpedanceHigh Level, 22K ohmsPhono MM, 47K ohms; 50 to 750pF, in 50pF stepsPhono MC: 25, 50, 100, 200, 400 or 1,000 ohms; 100pFOverall DimensionsC1000C:Width is 17-1/2 inches (44.45cm)Height is 6 inches (15.24cm) including feetDepth is 24 inches (61.0cm) including the Front Panel,Knobs and Interconnect Cables1C1000P:Width is 17-1/2 inches (44.45cm)Height is 6 inches (15.24cm) including feetDepth is 24 inches (61.0cm) including the Front Panel andInterconnect Cables1C1000T:Width is 17-1/2 inches (44.45cm)Height is 6 inches (15.24cm) including feetDepth is 24 inches (61.0cm) including the Front Panel andInterconnect Cables1WeightC1000C - 39.0 pounds (17.7 kg) net61.4 pounds (27.9 kg) in shipping cartonC1000P - 33.0 pounds (15.0 kg) net53.6 pounds (24.3 kg) in shipping cartonC1000T - 34.0 pounds (15.4 kg) net54.6 pounds (24.8 kg) in shipping carton1 Interconnect Cables are supplied with the C1000 Pream-plifier and C1000 Tube Preamplifier.
