The BASIS 922az provides the digital audio transport, signal
processing, control and status monitoring facilities needed
to bind a group of amplifiers and loudspeakers into an inte-
grated functioning system. In conjunction with QSCon-
trol.net software, the BASIS 922az enables the user to
design, test and deploy professional audio reinforcement
and distribution systems ranging in size from one to hun-
dreds of channels.
Each QSC power amplifier connects directly to a BASIS
922az via one of its four QSC DataPorts. All mission-critical
elements of the BASIS-driven sound system are monitored.
User-selected events are logged and loudspeaker protection
features unique to BASIS such as QSC's Driver Defense™
power limiter are made possible through the DataPort func-
tionality.
A standard Windows computer is the principle user-inter-
face for controlling the overall BASIS/QSControl system.
However, the BASIS 922az also offers a front panel inter-
face for accessing a few 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
BASIS devices in a system are configured, a computer is no
longer required on that system’s network. All basic func-
tions of the BASIS 922az continue to operate with or with-
out a control computer connected to the network.
The configurable DSP engine provides all of the functions
necessary to handle B-chain (the amp/loudspeaker portion
of a single chain) such as very flexible and precise cross-
overs, delays, equalization, compression/limiting, etc.
Audio enters a BASIS 922az 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.
