1. Technology Overview
1.1 Introduction to Technology
The Tight AV DSP system is a fixed architecture signal processing platform with powerful signal processing and routing options.
The hardware is equipped with analog audio interface connectivity, as well as digital audio using Dante for audio over Ethernet
and USB-audio as an interface for computers.
Tight AV DSP 1.0 is a Windows-based application used to configure and control the DSP hardware. An easy-to-use GUI gives
the user fast access to all the available processing functions. The unit has 16 built-in presets that can store the complete
configuration for later recall.
The Tight AV DSP can be controlled via the software, a dedicated wall panel controller or from 3
rd
party systems using the API
control protocol over RS-232/485 or Ethernet.
1.2 About Dante AES67
Dante/AES67 audio networking utilize standard IP networks to transmit high-quality, uncompressed audio with near-zero latency.
It's the most economical, versatile, and easy-to-use audio networking solution, and is scalable from simple installations to large-
capacity networks running thousands of audio channels. Dante/AES67 can replace multiple analog or multicore cables with a
single affordable Ethernet cable to transmit high quality multi-channel audio safely and reliably. With Dante software, the network
can be easily expanded and reconfigured with just a few mouse clicks. Dante/AES67 is the audio networking choice of nearly
all professional audio manufacturers, with hundreds of Dante-enabled audio products now available.

1.3 Audio Input Section
The DSP supports up to 4 balanced analog audio inputs available on removable phoenix connectors. The analog input section
supports microphone or line-level signals. +48VDC phantom power can be adopted for each input.
Preamp gain and phantom power can be conveniently controlled via Tight AV DSP 1.0 software.
1.4 Audio Output Section
The analog output section offers 4 balanced channels available on removable phoenix connectors. 24bit D/A conversion provides
excellent signal to noise ratio. With input and output faders set to 0dB the unit operates at unity gain. Nominal output level is+4dBu
with 20dB headroom. 0dBFS digital signal is equivalent to +24dBu.
