Specifications

The following applies to unit in Stereo mode with 8-ohm load and rated input sensitivity unless otherwise specified.

Sensitivity (volts RMS) for full rated power at 4 ohms: 1.4V Frequency Response (at 1 watt) 22 Hz to 22 kHz: �1 dB. Phase Response (degrees at 1 watt, 20 Hz to 20 kHz): +5�, - 18� Signal-to-Noise Ratio: A-weighted, below rated power: > 102 dB. 22Hz to 22kHz, below rated power: > 97 dB. Total Harmonic Distortion (THD) at full bandwidth power, from 20 Hz to 20 kHz: < 0.5%. Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) from full rated output to -40 dB: < 1%. Damping Factor (8 ohm) 10 Hz to 400 Hz: >200. Crosstalk (below rated power): Xs700 (1 kHz, 20 kHz): > 55 dB, > 55 dB Voltage Gain (at maximum level setting): Xs500: 32:1 (30.1 dB) Load Impedance: Safe with all types of loads. 2 to 8 ohms in Stereo, 4 to 8 ohms in Bridge Mono. AC Line Voltage and Frequency Configurations: Available (�10%): 120VAC/60 Hz and 230VAC/50 Hz. Controls Level: Two front-panel, gray rotary level controls, one for each channel. Power On: Front-panel switch; on when in the right-hand position. Indicators Signal: Two green LEDs, one for each channel, illuminates when the channel's input signal level is above -40 dBu. Clip: Two front-panel red LEDs, one for each channel, illuminates when the channel's output signal is being overdriven. Power: Yellow front-panel LED indicates amplifi er has been turned on and AC power is available. AC Mains: Red front-panel LED indicates the presence of AC power at the power cord, even if the amplifi er is not turned on. Fault: Red front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefl y during normal power-up when amplifi er is first switched on. Bridge: Yellow LED indicates that amplifier is in bridge mode Temp: Red LED indicates that channel(s) are in thermal protect mode.

Input Connectors XLR-1/4" combo connectors: One per channel, 3-pin female XLR connector and TRS 1/4" phone jack accept balanced or unbalanced signals. 3-pin Phoenix-style connectors: One per channel, accepts balanced or unbalanced signals. Input Impedance (nominally balanced, nominally unbalanced): 20 k ohms, 10 k ohms.

Output Connectors Balanced XLR connectors: One per channel, 3-pin male XLR connector in parallel with XLR-1/4" combo and Phoenix-style input connectors for daisychain operation. 5-Way binding post output connectors: One pair per channel; accept banana plugs, spade lugs or bare wire. 4-Pole Speakon output connector: One connector per channel. Accepts a 4-pole Speakon connector. DC Output Offset (shorted input): �75 millivolts. Output Signal: Stereo, unbalanced, two-channel

Protection Xs Series amplifi ers provide extensive protection and diagnostic capabilities, including output current limiting, microprocessor-controlled DC protection, circuit breaker, and special thermal protection for the unit's transformers.

Construction Ventilation: Flow-through ventilation from front to back Cooling: Internal heat sinks with forced-air cooling for rapid, uniform heat dissipation. Dimensions: EIA Standard 19 inch (48.3 cm) rack mount width (EIA RS-310-B), 3.5 inch (8.9 cm) height and 15.675 inch (39.8 cm) depth behind the mounting surface.
