Introduction

The RAVE 522ua provides the digital audio transport, and signal processing needed to bind a group of amplifiers and loudspeakers into an integrated functioning system. In con- junction with QSControl.net software, the RAVE 522ua enables the user to design, test and deploy professional audio reinforcement and distribution systems ranging in size from one to hundreds of channels.

Astandard Windows computer is the principle user-inter- face for controlling the overall RAVE/QSControl system. However, the RAVE 522ua 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 RAVE 522ua 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 RAVE 522ua either through analog universal inputs (mic to line level with software-selectable +48V phantom power) or from CobraNet source devices such as QSC's line of RAVE digital audio routers. Any combination of 16 CobraNet channels (selected from up to 4 bundles of 32 channels) can be routed into the 24 x 24 DSP engine. Any or all of the 24 DSP channels can also be routed to up to 32 CobraNet channels on the network.

Unlike many configurable DSP boxes, the intrinsic process- ing latency of the RAVE 522ua is both short and fixed at 0.396 milliseconds. When analog input and analog outputs are used, the total delay is 2.354 milliseconds. The delay

522ua specifications

The QSC Audio 522ua is a cutting-edge amplifier designed to meet the demands of professional audio environments. This versatile 2-channel amplifier delivers a robust performance, making it an ideal choice for installations in various settings such as auditoriums, theaters, and multi-purpose venues.

One of the standout features of the 522ua is its exceptional power output. With a continuous output of 250 watts per channel at 4 ohms, it ensures that audio signals are delivered with clarity and strength. This amplifier is built to handle both low and high impedance loads, providing flexibility for different speaker configurations. What’s more, its dynamic power capabilities allow for peaks up to 450 watts, ensuring that even the most demanding audio content is reproduced with stunning accuracy.

At the heart of the QSC 522ua is the innovative PowerLight technology, which combines efficiency and performance. This technology not only contributes to reduced power consumption but also results in lower operating temperatures, enhancing the reliability and longevity of the amplifier. The compact design of the 522ua ensures it can fit into tight spaces while still providing ample power, catering to the needs of various installations.

Another important feature is the integrated DSP (Digital Signal Processing), which allows users to fine-tune audio output for optimal performance. The DSP includes functions such as equalization, delay, and crossover settings, enabling precise control over sound reproduction. The intuitive user interface, along with the LCD display, makes navigating through the amplifier's features and settings seamless.

Moreover, the 522ua is equipped with advanced protection circuitry that safeguards the amplifier against thermal overload, short circuits, and other potential issues. This reliability ensures uninterrupted performance during critical audio tasks.

In addition, the amplifier's network capabilities allow for remote monitoring and control through the QSC Q-SYS platform or other compatible systems, integrating it easily into modern audio networks. With its combination of power, reliability, and advanced technology, the QSC Audio 522ua stands out as an outstanding amplifier option for professional audio applications. Whether for live performance, installation, or broadcast, it delivers unmatched performance that audio professionals have come to trust.
