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.
