    Pulse-Eight ProAudio1632 DSP Preamplifier

    The ProAudio1632 DSP Pre-Amp Audio Matrix features 40 audio inputs alongside 32 analog outputs and 32 digital outputs, enabling simultaneous audio distribution to multiple zones. Each output zone can be enhanced with built-in features including 5 band equalizer on each zone, adjustable volume and gain settings, subwoofer control, serial and TCP/IP control, lip sync delay and much more.

    ProAudio has been designed for the custom install AV market, in many cases the need for an audio receiver can be eliminated by using the audio features of the ProAudio™ Series.

    Doorbell/Paging Features

    The doorbell connections on the reverse of the system provides the ability to connect doorbell/pager inputs to any output zone and to automatically lower the current volume and push through the doorbell/pager signal. This can also be adapted for fire/evacuation messages.

    Volume and Tone Controls

    For muted audio or the lowest possible distortion, by mirroring the analog outputs to the digital outputs, you can input and output digital audio, completely bypassing the analog sections. No extra conversions are required and you still have volume, balance, bass, treble and 5 band equalizer controls.

    Automatic Audio Conversion

    Whether your audio comes in through the analog inputs, digital coax inputs or digital optical inputs, all inputs can be converted to analog to provide full flexibility.

    Stereo to Mono Downmix for Each Zone

    For hallways, and outdoor speakers, where stereo is not particularly useful, each zone can be mixed from stereo to mono using a variety of different methods.

    Lip Sync Delay

    When moving audio around, lip sync can often be an issue. Within each ProAudio system, we provide up to 170ms of lip sync delay so that your audio/video matches up.
