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.
A standard 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-sele48V
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
