QSControl.net Network: Basis + Rave

Basis + Rave Network Audio System

QSControl.net: Basis+Rave

QSControl.net is a networked audio system platform that seamlessly integrates QSC's Amplifier and Loudspeaker Management, Configurable Digital Signal Processing and Digital Audio Transport into a unified system administered through a user-friendly GUI. QSC's BASIS, RAVE 522ua and DSP 322ua devices all operate under QSControl.net, networked and controlled from Venue Manager software. Furthermore, multiple networked computers can control and monitor all units simultaneously. QSControl.net is AMX® and Crestron® compatible.



BASIS processors include Amplifier and Loudspeaker Management, Configurable DSP and CobraNet Digital Audio Transport in a compact 1RU device. BASIS processors can be generally considered a superset of the RAVE and DSP 322ua devices.

Automatic Power Limiting* is one of the most powerful features of the BASIS products. This technology establishes a feedback loop between QSC's speakers and amps that assesses the driver's thermal response to the true power delivered to it and uses this information to dynamically limit the power allowed to reach the driver. Power Limiting has no effect on the sound until the designated thermal limit is exceeded, beyond which the power to the driver is reduced to a safe level. This maximizes each loudspeaker's performance without exceeding its safe operating range.

Previous configurable DSP systems have often suffered from the problem of variable latency for signal propagating through different processing paths. QSC has solved this problem by yielding a short, fixed processing latency through its DSP subsystem, regardless of the signal path.

BASIS processors connect directly to the DataPort on select QSC amplifiers, providing network control and monitoring of amplifier functions. All models incorporate the DSP functions discussed in Venue Manager Software.


In addition to its Digital Audio Transport functions, the RAVE 522ua incorporates DSP functions controlled by Venue Manager Software.

DSP 322ua

The DSP 322ua operates under QSControl.net but without CobraNet Digital Audio Transport capability. It incorporates DSP functions controlled by Venue Manager Software.

* BASIS Automatic Power Limiting is patented by QSC (U.S. patent number 6,940,981)

All of the BASIS, RAVE and DSP devices operate under the same Venue Manager software . The units differ by the inputs and outputs that they offer.
