Circuit Topology | A fully modular, fully differential, fully balanced 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 Hâ„¢ power supply topology, and microprocessor-controlled fault protection |
Audio Specifications | The XPA-DR3 features three Differential Referenceâ„¢ Amplifier Modules |
Audio Specifications (Three Differential Reference Amplifier Modules) | Power Output (all three channels driven): 450 watts RMS, per channel, into 8 Ohms, at <0.1% THD. 600 watts RMS, per channel, into 4 Ohms, at <0.1% THD. Power Bandwidth (at rated power; 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.1 dB). Broad Band Frequency Response: 20 Hz to 50 kHz +0/-2 dB. THD + noise: < 0.008%; at 100 watts RMS; 1 kHz; 8 Ohms. Signal to Noise Ratio (8 Ohm load): > 120 dB; ref FTC rated power; unbalanced input (A-weighted). > 96 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): 2.0 V. Gain: 29 dB. Input Impedance: 33 kOhms (balanced). 23.5 kOhms (unbalanced). |
Input And Output Connections Input Connections | Unbalanced (RCA); balanced (XLR); one each, per channel, user 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 |
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-DR3 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions |
