Crestron ST-VC

ST-VC – Cresnet Volume Control Module

The Crestron SmarTouch™ STS system is the most user-friendly RF wireless control system on the market today. The basic SmarTouch system (control processor and touchpanel) will accommodate many installations. If you want something more customized or need to include additional devices, our line of expansion modules is just what you need. Each expansion module connects easily to your SmarTouch system. A virtually infinite number of modules can be connected to accommodate all of your system needs. Housed in metal enclosures that match the control processor, modules are rack-mountable with an optional kit.

ST-VC is a digitally controlled 3-channel audio attenuator. Each channel has independent settings for volume, treble, bass and mute. ST-VC is ideally suited to provide full audio control for systems without an IR-controlled integrated receiver. Choose your mixer, preamp and amplifier, then add an ST-VC module to complete the system. In some applications ST-VC's separate control of treble and bass may even eliminate the need for a graphic equalizer.
