* Load Impedance: Safe with all types of loads. Rated for 2 to 16 ohms in Stereo, 4 to 16 ohms in Bridge-Mono and 1 to 4 ohms in Parallel-Mono mode.
* Required AC Mains: 50/60 Hz; 100, 120, 220 and 240 VAC (10%) units are available. All draw 100 watts or less at idle. Current, voltage and frequency requirements are provided on the units back panel.
* Performance
* Frequency Response: 0.1 dB from 20 Hz to 20 kHz at 1 watt.
* Phase Response: 10 degrees from 10 Hz to 20 kHz at 1 watt.
* Signal-to-Noise Ratio: A-weighted: Better than 105 dB below rated full bandwidth power.
* 20 Hz to 20 kHz: Better than 100 dB below full bandwidth power.
* Total Harmonic Distortion (THD) at full bandwidth power: Less than 0.05% from 20 Hz to 1 kHz increasing linearly to 0.1% at 20 kHz.
* Inter-modulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.05% from 163 mW to full bandwidth power.
* Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz.
* Slew Rate: (Slew rates are limited to useful levels for ultrasonic/RF protection). Greater than 13 volts per microsecond.
* Controls
* Enable: A front panel push button used to turn the amplifier on and off.
* Level: A front panel rotary control for each channel with 31 detents used to control the output level.
* Stereo/Mono: A three-position back panel switch used to select Stereo, Bridge-Mono or Parallel-Mono mode.
* Sensitivity: A three-position switch inside the PIP compartment used to select the input sensitivity for both channels: 0.775 volts or 1.4 volts for standard 1kHz power, or a 26 dB voltage gain.
* Reset: A back panel push button for each channel used to reset the circuit breaker that protects each power supply.
* Input Ground Lift: This switch on the PIP2-FXQ is used to isolate input signal grounds from chassis ground to prevent ground loops.
* Indicators
* Indicators
* Enable: This amber front panel indicator shows the on/off status of the low-voltage power supply.
* Signal/IOC: Each channel has a green front panel indicator that flashes to show amplifier output. If a channels output waveform differs from its input by 0.05% or more, the indicator flashes brightly to show distortion. This function provides proof of distortion-free performance. In Parallel-Mono mode, the Channel 2 light stays on.
* ODEP: Each channel has an amber front panel indicator that shows thermal-dynamic energy reserve. Normally, each ODEP indicator is lit to show available reserve energy. In the rare event that a channel has no reserve, its indicator will dim in proportion to ODEP limiting. An ODEP indicator may also turn off under other conditions
* 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
* Construction
* Steel chassis with durable black finish, aluminum front panel with Lexan overlay, and specially designed flow-through ventilation from front to side panels.
