Introduction
The BASIS 722az provides the signal processing, control and status monitoring facilities needed to bind a group of amplifiers and loud-
speakers into an integrated functioning system. In conjunction with QSControl.net software, the BASIS 722az enables the user to
design, test and deploy professional audio reinforcement and distribution systems.
Each QSC power amplifier connects directly to a BASIS 722az 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 power limiter are made possible through the DataPort functionality.
A standard Windows computer is the principle user-interface for controlling the overall BASIS/QSControl system. However, the BASIS
722az also offers a front panel interface for accessing a few critical functions.
A single QSControl 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 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 BASIS 722az continue to operate
with or without a control computer connected to the network.
Audio enters a BASIS 722az through analog line inputs, is processed per your custom DSP configuration, and output via the DataPorts.
Unlike other configurable DSP boxes, the intrinsic processing latency of the BASIS 722az 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.
Both software and firmware can be easily updated over the network. In the future, QSC will be adding new capabilities to both BASIS
and QSControl.net. Our latest code releases and access to up-to-date information on BASIS and QSControl.net are available at
www.qscontrol.net. We invite you to visit us there.
We've applied our many years experience in supporting high-end installed sound with our previous system-building products such as
RAVE, QSControl, CM16a, DSP-3, DSP-4, and DSP-30. The BASIS 722az brings all that technology together in one compact, powerful,
easy to use system. We are confident that your new BASIS 722az will provide years of dependable service and we hope it will help you,
the system designer and implementer, to express your creative audio system ideas.
