MXAV333 QwikBUS™ Intelligent Audio/Video Mixer

The Alpha Communications® / S.T.R.™ MXAV333 intelligent mixer is used primarily with the QwikBUS™ series intercom or video-intercom systems for systems. The MXAV333 provides the intelligent circuitry needed to install multiples of 100 audio QwikBUS™ stations, or multiples of up to 40 video QwikBUS™ stations, allowing systems with very large system capacities.

Each MXAV333 gets its power from its associated SP333 intelligent controller and corresponding SNT333 power supply. All MXAV333 field connections are positive screw terminal type, or plugin type. Each MXAV333 requires the SP333 and SNT333, and C333-2 connecting cable assembly.

The MXAV333 can also directly replace the older model MXA333 and/or MXV333 mixers.
