Product Highlights:

  • Power Output:

    • 180 watts x 5 channels at 8 ohms
    • 255 watts x 5 channels at 4 ohms
    • 225 watts x 2 channels at 8 ohms
    • 350 watts x 2 channels at 4 ohms
    • Power measurements based on 120VAC with 0.05% THD, RMS continuous power across the full audio band (20 Hz - 20 kHz)

  • Circuitry:

    • Class A/AB circuitry designed by renowned engineer John Curl
    • Direct-coupled design with no capacitors or inductors in the audio path for a clean signal

  • Inputs:

    • Balanced XLR inputs featuring discrete circuits for superior signal integrity

  • Power Handling:

    • Frequency response from 5 Hz to 100 kHz, +0/-3 dB
    • Full power rated down to 5 Hz for unrestricted low-end bass
    • Dynamic headroom greater than 1.5 dB
    • Slew rate of over 130 volts per microsecond for quick response to signal changes

  • Precision and Clarity:

    • Total harmonic distortion (THD) less than 0.05% at full power
    • Intermodulation (IM) distortion less than 0.04%
    • Transient Intermodulation Distortion (TIM) is unmeasurable for the cleanest audio output

  • Construction:

    • Custom 1.5 kVA encapsulated toroid power transformer with independent secondary windings for each channel
    • Hand-matched JFETs in the input stage and hand-matched MOSFETs in the driver stage for optimal component performance
    • Beta-matched 15 amp, 60 MHz bipolar output transistors (3 pairs per channel)
    • 100,000 µF power supply filter capacitance ensures clean, stable power

  • Additional Features:

    • Auto turn-on by audio signal or 12V trigger
    • DC Servo and relay protection circuits to safeguard your system
    • Heavy-duty 24k gold-plated, 5-way speaker terminals for secure connections
    • Interchannel crosstalk greater than 78 dB at 1 kHz and 63 dB at 20 kHz

  • Power Requirements:

    • Standby power consumption: 1 watt
    • Idle power consumption: 125 watts
    • Maximum power consumption: 1500 watts

  • Signal-to-Noise Ratio (S/N):

    • Greater than 112 dB (IHF A-weighted, input shorted)
    • Greater than 102 dB (unweighted, input shorted)

  • Damping Factor:

    • Greater than 1100 at 20 Hz for tight control over speaker movement
