Studio Technologies Model 780-02 Central Controller

The 780-02 system provides digital inputs and analog outputs.

Creating and distributing eight channel (7.1) surround audio material has become common for entertainment, cinema, and allied applications. As such, the ability to simply and effectively monitor these sources is imperative during the recording and post-production process. Studio Technologies has addressed these needs with the StudioComm for Surround Model 780-02 Central Controller and the Model 790 and Model 71 Control Consoles. With digital audio inputs, analog monitor output, support for multiple user control surfaces, and an extensive set of resources it's a simple task to integrate a monitoring system into virtually any facility. The carefully selected group of features, including two surround (7.1) and one stereo input, configurable input-source time delay, LFE low-pass filter, analog surround (7.1) monitor output, configurable downmix and mute/solo functions, and bass management, along with a multi-format sync input, make the system powerful yet simple to operate. And by using the best of contemporary technology, as well as following rigorous design practices, the system's audio quality is excellent.
