The XPA-5 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-5 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).
The XPA-5 Gen3 features five of our High-Powered Single Channel Modules.
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.
250 watts RMS/channel; THD<0.1%; 8 Ohms; ALL FIVE 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.
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 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.
