    • Uses PBTL topology for cleaner sound
    • On board heat sink and fan eliminates the need for external fans
    • Small footprint for space limited applications
    • Thermal and short circuit protection
    • Delivers up to 100W RMS per channel
    • Startup and power down pop elimination
    • 15 to 30 VDC power supply required

    A low noise, temperature controlled, cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Thermal, over/under voltage, and current protection circuits are also included to extend the longevity of the amplifier board. Mounting holes are provided as is a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection. RCA line-level inputs are pre-attached to make this board ready to rock.

    Solid performer, the fan is very quiet indeed, and the frequency response extends downward to 0.5Hz that I have measured, (with some expected attenuation, approx. 6dB), but still there and available at full rated RMS power.
