1 UAP-1783 Eight Channel Universal Audio Processor

1.1 Introduction

The UAP-1783 is an eight-channel high quality audio processor designed to work alone or with a wide

range of video converters, frame synchronizer proc/amps of the Densité series.

The card features two distinct processing blocks: Input and Output. The input processing includes Dolby

detection, Tone generator, delay adjustments, level controls and phase correction. Delay components

include a fixed delay of up to 2 seconds as well as a video tracking delay that will automatically track the

varying saw tooth delay introduced by an associated video frame synchronizer.

The output processing block includes full channel shuffling, an additional gain/attenuation stage and

mixing. Each odd output channel is a mix of any two input channels, and a 4-channel mixing is available

on the even output channels. Additional audio functions such as dynamic processing (compressor/limiter

and expander) and/or Down and Up mixing are available as options.

With a card-to-card Audio bus, the UAP-1783 provides processing for 8 channels originating from a video

card. Once processed, the signals are sent back to be embedded, and are also available at the analog and

digital outputs.

Along with the audio channels, the Audio bus carries the timing, delay signaling and Dolby Metadata.

When combining cards together all audio processing is synchronous and in phase, ensuring proper

alignment and matched delay. The UAP-1783 can work with one video card and/or one other audio

processor card.

User-defined channel identification data may be encoded in the AES status bits. An input audio signal

status is also available indicating the input signal presence or overload.

The card is housed in a (DENSITÉ) frame, with a single or double width rear connector panel. Based on

the rear module installed, the UAP-1783 is compatible with the AES3 or AES-3id digital audio standard.
