Emotiva XPA DR-3 päätevahvistin 3 x 600w 4ohm ominaisuuksilla.

The XPA-DR3 is a high-powered three-channel audiophile power amplifier that combines the exceptional accuracy and finesse of a true balanced differential design with the power you need to deliver musical crescendos and movie special effects with stunning realism and impact. Whatever your listening preferences, the XPA-DR3 will give you the combination of detail and power than only a fully differential amplifier can provide.


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 H™ power supply topology, and microprocessor-controlled fault protection.

Audio Specifications

The XPA-DR3 features three Differential Reference™ 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.

Mechanical

  • Dimensions: 432 x 203 x 483 mm

  • Weight: 22,4 kg
