1 x 250W Power Amplifier
USB/RS232 Control w mini DSP

The HSP series is Australian Monitor's next generation of controllable Class D power amplifiers, delivering high quality audio reinforcement with the power you need in the following options -Single channel 120W or 250W, Dual channel 120W or 250W and Quad channel 120W or 250W.

Our new power amplifiers are fully featured, including an efficient Class D amplifier, USB and RS232 control and a mini DSP featuring volume control, mute, compressor/limiter, filter and input channel selection.

The HSP series power amplifiers give the AV contractor a reliable amplifier for applications that are price sensitive yet still require high quality commercial sound reinforcement and control.

    Class-D Amplifier

    The HSP amplifiers use an efficient Class-D amplifier topology allowing a greater power density with a much lower weight.
    All amplifier channels offer 100V, 70V and 4Ω output options so you can choose the output configuration to match your application.

    PC Control Application

    Take control of your amplifier using the HSP Control Software.

    The control software allows you to modify signal routing, DSP settings, channel naming, retrieve status information and more.
    Download it now from the download section of this page and see what the HSP amplfier can do.

    Integrated mini DSP

    The HSP amplifiers include a mini DSP engine with the following features,
    • Input/Output Router
    • High, Low Pass Filters
    • Compressor / limiter
    • Mute
    • Inversion

    3rd Party Control

    Take further control of the HSP amplifiers with 3rd party system support over USB or RS232.
    Enter "Developer Mode" in the PC application to easily see the commands being sent and received from the amplifier.
    The HSP control protocol can be found in the manual.
