QSControl.net™ Wall Control Plate Accessories

I. INTRODUCTION

The WCP-1 and WCP-2 are wall control plate accessories for QSControl.net network audio system components, such as Basis, RAVE, and DSP products. They allow an installer to create simple, non-computer user interfaces for these products in sound systems. As a result, end users don’t need to learn the QSControl.net software or anything technical about the system to adjust volume, select audio sources, choose presets or snapshots, or other control functions.

The WCP accessories connect to one or more of the unit’s OmniPort inputs, which accept both analog control input via variable DC voltage or variable resistance and digital control input via TTL-type logic.

The WCP accessories provide two ways to connect to the QSControl.net unit: an RJ-45 jack, for use with Cat 5 or Cat 6 network cable, or a screw

terminal strip for use with individual wires. Note: You must assign any functions to their respective OmniPort inputs in the QSControl.net VenueManager application.

Mounting

The WCP accessories mount in the type of plastic A/V wall box commonly used in North America. They fit any Decora™-style trim plate. The front panels have spaces for labeling functions, names, etc. Each accessory comes with a sheet of labels printed with commonly used terms.

If you mount a WCP accessory in a metal electrical box, you may have difficulty plugging a cable into the RJ-45 jack on the back of the accessory.

II. WCP-1 ROTARY POTENTIOMETER CONTROL

The control element of the WCP-1 is a 10 kΩ linear taper potentiometer with 11 detents marked 0 (fully counterclockwise) to 10 (clockwise). It connects to any OmniPort on the QSControl.net unit and can be wired so that maximum resistance is at full clockwise or at full counterclockwise.

Figures 1–4 depict how to connect the WCP-1 to an OmniPort.
