The ProAudio3248 DSP Pre-Amp Audio Matrix features 80 audio inputs (32 x Stereo Analogue, 32 x Digital Coaxial & 16 Digital Optical) and 96 audio outputs. The outputs being 48 analogue outputs (48 = Stereo Left/Right) and 48 digital outputs (Digital Coaxial), 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.
The ProAudio range 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.
Drivers for multiple control systems are supported (contact us).
5 BAND GRAPHIC EQUALIZER ON EACH ZONE:
The ProAudio™ series provides maximum sound control including bass, treble and a 5 band graphic equalizer available for each zone. Audio and tone control are adjustable in 0.5dB steps, and all allow direct or relative adjustments (Ex: Set the volume to an absolute -12.5dB, or increase it by 3.0dB). The tone controls have a range of +/-20dB.
ADJUSTABLE GAIN SETTINGS ON EACH INPUT:
To balance the different levels of audio coming from different pieces of equipment, each audio input has a full range gain adjustment. The adjustment range is: +24dB to -99.5dB, or full mute, in 0.5dB increments.
With low pass and high pass filter settings adjustable from 50Hz to 300Hz, selectable 12db/24db per octave slope with Butterworth or Linkwitz-Riley filters and selectable polarity for each zone, the ProAudio provides easily adaptable subwoofer control.
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 WORK ON THE DIGITAL INPUTS AND OUTPUTS:
For the extreme in ultra-quiet audio and lowest possible distortion, by mirroring the analogue outputs to the digital outputs, you can input and output digital audio, completely bypassing the analogue sections. No extra conversions are required and you still have volume, balance, bass, treble and 5 band equalizer controls.
AUTOMATIC AUDIO CONVERSION:
It makes no difference 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 flexiblity.
Note: The ProAudio™ does not down convert DTS or 5.1 Dolby audio. When DTS or 5.1 Dolby audio is detected, it is passed straight through from the digital coax input to the digital coax outputs. Analogue inputs cannot be directly converted to digital outputs. To convert analogue to digital, a digital output can mirror an analogue output.
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 matchup doesn’t look like a 1950’s Godzilla movie.
Lock as many output zones as you wish to create a group of outputs that all automatically switch simultaneously to the same input source.
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.
KEEP IT SIMPLE SERIAL™:
Available through the TCP/IP port or the RS-232 port, Pulse-Eight's K.I.S.S.™ is one of the easiest to use, serial port protocols, on the market. Yet the extensive bi-directional command set allows total control over the ProAudio.
