Introduction

The BASIS 914lz 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 914lz 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 914lz 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.

Astandard Windows computer is the principle user-inter- face for controlling the overall BASIS/QSControl system. However, the BASIS 914lz also offers a front panel interface for accessing a few 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 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 914lz 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 BASIS 914lz either through analog XLR/TRS combo inputs (line level) or from CobraNet source devices such as QSC's line of RAVE digital audio routers. Any combi- nation of 16 CobraNet channels (selected from up to 4 bun- dles 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 other configurable DSP boxes, the intrinsic process- ing latency of the BASIS 914lz is both short and fixed at
