Introduction

The DSP 322ua provides signal processing needs for an integrated functioning system. In conjunction with QSCon- trol.net software, the DSP 322ua enables the user to design, test and deploy professional audio reinforcement systems ranging in size from one to hundreds of channels.

Astandard Windows computer is the principle user-inter- face for controlling the overall DSP/QSControl.net system. However, the DSP 322ua also offers a front panel interface for accessing critical functions.

A single QSControl.net server computer can support several clients running QSC's latest Venue Manager software. Thus, the sound system can be operated via several computers, roaming wireless laptops, tablets, etc., all at the same time, from anywhere a connection to the QSControl.net network is available.

The QSControl.net network can also be managed from a sin- gle computer running both the client and the server. Once all

QSControl devices in a system are configured, a computer is no longer required on that system’s network. All basic func- tions of the DSP 322ua continue to operate with or without a control computer connected to the network.

The configurable DSP engine provides all of the functions necessary to handle the amp/loudspeaker portion of a sig- nal chain, such as very flexible and precise crossovers, delays, equalization, compression/limiting, etc.

Audio enters a DSP 322ua through the 8 universal analog inputs. The inputs accept everything from mic to line level and are equipped with software-selectable +48V phantom power.

Unlike many configurable DSP boxes, the intrinsic process- ing latency of the DSP 322ua is both short and fixed at 0.396 milliseconds. With analog inputs and analog outputs, the total delay is 2.354 milliseconds. The delay does not change
