The RAVE 522aa 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 522aa 
enables the user to design, test and deploy professional 
audio reinforcement and distribution systems ranging in size 
from one to hundreds of channels. 

A standard Windows computer is the principle user-inter-
face for controlling the overall RAVE/QSControl system. 
However, the RAVE 522aa also offers a front panel interface 
for accessing critical functions. 

A single QSControl server computer can support several cli-
ents 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 network is 
available. 

The QSControl network can also be managed from a single 
computer running both the client and the server. Once all 
devices in a system are configured, a computer is no longer 

required on that system’s network. All basic functions of the 
RAVE 522aa continue to operate with or without a control 
computer connected to the network.

Audio enters a RAVE 522aa either through analog line 
inputs or from CobraNet source devices such as QSC's line 
of RAVE digital audio routers. Any combination of 16 Cobra-
Net 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 522aa 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 
does not change regardless of the DSP configuration, unless 
the configuration intentionally adds more delay. 

The RAVE 522aa also supports the new optional low-latency 
CobraNet feature that provides transport at only 2.66 milli-
seconds delay. 

See page 14 for detailed descriptions.
