• The XPA-7 Gen3 is a fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete, dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.

• The XPA-7 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).

• Power Output: 300 watts RMS/channel; 20 Hz – 20 kHz; THD<0.1%; 8 Ohms; one channel driven.550 watts RMS/channel; 20 Hz – 20 kHz; THD<0.2%; 4 Ohms; one channel driven. 300 watts RMS/channel; THD<0.1%; 8 Ohms; two channels driven. 490 watts RMS/channel; THD<0.1%; 4 Ohms; two channels driven. 200 watts RMS/channel; THD<0.1%; 8 Ohms; ALL SEVEN channels driven.

• Power Bandwidth (at rated power; 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.1 dB).

• Broad Band Frequency Response: 5 Hz to 80 kHz +0/-2 dB.

• THD + noise: < 0.005%; at 100 watts RMS; 1 kHz; 8 Ohms.

• Signal to Noise Ratio (8 Ohm load): > 117 dB; ref FTC rated power; unbalanced input (A-weighted). > 91 dB; ref 1 watt; unbalanced input (A-weighted).

• Minimum Recommended Load Impedance (per channel): 4 Ohms (which equals one 4 Ohm load or two paralleled 8 Ohm loads).

• Damping Factor (8 Ohm load): > 500.

• Input Sensitivity (for rated power; 8 Ohm load): 1.5 V.

• Gain: 29 dB.

• Input Impedance: 33 kOhms (balanced). 23.5 kOhms (unbalanced).

• Input Connections (High-Powered Single Channel Modules): Unbalanced (RCA); balanced (XLR); one each per channel, independently selectable.

• Input Connections (Stereo Modules): 2 Unbalanced (RCA); 2 balanced (XLR); two per channel, independently selectable.

• Speaker Output Connections: Audiophile grade, gold plated, 5-way binding posts.

• Trigger: Trigger Input: 5 – 12 V (AC or DC); <10 mA input current required. Trigger Output: 12 VDC; can drive any load up to 120 mA.

• Between 100 VAC and 250 VAC @ 50 / 60 Hz (automatically detected).

• Standby: push button (halo ring changes color to indicate Standby or On).

• Status LEDs: one per channel; blue. Status LEDs change to red to indicate a fault condition.

• AC Power switch: rocker switch (switches AC main power).

• Status LEDs switch: disables front panel Status LEDs and dims Standby button halo.

• Input selector switches (one per channel):  metal toggle switches; select between balanced and unbalanced inputs.

• Circuit Breaker: press button to reset circuit breaker.

• The XPA Gen3 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions.

• Dimensions: 17” wide x 8” high x 19” deep (unboxed; including feet). 17” wide x 7” high x 19” deep (unboxed; without feet). 24-1/2” wide x 12” high x 24-3/4” deep (boxed).
