Input/Output

• Input Connector: Two balanced 1/4-inch phone jacks on the back panel and two balanced three-pin female XLR connectors on the factory-installed PIP2-FXQ.

• Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 k ohms, unbalanced.

• Input Sensitivity: Settings include 0.775 volts or 1.4volts for standard 1 kHz power, or a 26 dB voltage gain.

• Output Connectors: Two sets of color-coded 5-way binding posts (for banana plugs, spade lugs or bare wire).

• Output Impedance: Less than 10 milliohms in series with less than 2 microhenries.

• DC Output Offset: (Shorted input) 10 millivolts.

Output Signal

• Stereo: Unbalanced, two-channel.

• Bridge-Mono: Balanced, single-channel. Channel 1 controls are active; Channel 2 should not be used.

• Parallel-Mono: Unbalanced, single-channel. Channel 1 controls are active; Channel 2 controls are bypassed.

Protection

• Macro-Tech amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature, chain destruction phenomena, input overload damage and high-frequency blowups. They also protect loudspeakers from input/output DC and turn-on/turn-off transients. If unreasonable operating conditions occur, the patented ODEP circuitry will proportionally limit the drive level to protect the output transistor stages, particularly in the case of elevated temperature. Transformer overheating will result in a temporary shutdown of the affected channel; when it has cooled to a safe temperature, the transformer will automatically reset itself. Controlled slew-rate voltage amplifiers prevent RF burnouts. And input overload protection is provided by current-limiting resistance at the input.

• Turn On: Four-second delay with no dangerous transients.

Construction

• Steel chassis with durable black finish, aluminum front panel with Lexan overlay, and specially designed flow-through ventilation from front to side panels.

• Cooling: Internal heat sinks with forced-air cooling for rapid, uniform heat dissipation.

• Dimensions: Standard 19-inch (48.3-cm) rack mount width (EIA RS-310-B), 3.5-inch (8.9-cm) height, 16 inch (40.6-cm) depth behind the mounting surface and 2.5-inch (6.3- cm) protrusion in front of the mounting surface.

• Approximate Weight: Center of gravity is 6inches (15.2cm) behind front mounting surface.
