XPA-11 Gen3 Eleven Channel Power Amplifier

£2,399.00Price

11 CHANNEL AUDIOPHILE HOME THEATER POWER AMPLIFIER

  • Circuit Topology

    • The XPA-11 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-11 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).

    Audio Specifications

    The XPA-11 Gen3 features three of our High-Powered Single Channel Modules and four of our Stereo Modules.  

    Audio Specifications (High-Powered Single Channel Modules):

      Trigger Output: 12 VDC; can drive any load up to 120 mA.

    Power Requirements

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

    Front Panel Controls and Indicators

    • 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.

    Rear Panel Controls

    • 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.

    Protection

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