IMPORTANT SAFETY PRECAUTIONS & EXPLANATION OF SYMBOLS
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to
the presence of uninsulated “dangerous” voltage within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to humans.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in this manual.
SAFEGAURDS
Electrical energy can perform many useful functions. This unit has been engineered and manufactured to
assure your personal safety. Improper use can result in potential electrical shock or fire hazards. In order
not to defeat the safeguards, observe the following instructions for its installation, use and servicing.
CAUTION: To reduce the risk of electric shock, do not remove the cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.
WARNING: To prevent fire or electric shock, do not expose this equipment to rain or moisture.
1- Maximum operating ambient temperature is 50°C (122°F).
2- Never restrict airflow through the device fan or vents. Please insure that the air intake and exhaust
vents are unobstructed.
3- When installing equipment into rack, distribute the units evenly. Otherwise, hazardous conditions
could be created by an uneven weight distribution.
4- Connect the unit only to a properly rated supply circuit. The BASIS 722az is suitable for connection to
100 - 240 VAC, 47 - 440 hertz, with no special considerations other than the appropriate IEC power cord.
5- Reliable Earthing (Grounding) of rack-mounted equipment should be maintained.
LITHIUM BATTERY WARNING
THIS EQUIPMENT CONTAINS A NON-RECHARGEABLE LITHIUM BATTERY. LITHIUM IS A CHEMICAL
KNOWN TO THE STATE OF CALIFORNIA TO CAUSE CANCER OR BIRTH DEFECTS. THE NON-RECHARGE-
ABLE LITHIUM BATTERY CONTAINED IN THIS EQUIPMENT MAY EXPLODE IF IT IS EXPOSED TO FIRE OR
EXTREME HEAT. DO NOT SHORT CIRCUIT THE BATTERY. DO NOT ATTEMPT TO RECHARGE THE NON-
RECHARGEABLE LITHIUM BATTERY.
FCC INTERFERENCE STATEMENT
NOTE: This equipment has been tested and found to comply with the limits for a class B digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and if not installed and used in accordance to the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television recep-
tion, which can be determined by switching the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio or TV technician for help.

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.
