Non-QSControl.net applications

The WCP-1 can be used for non-QSControl.net analog applications, such as variable passive signal attenuation or a variable voltage divider (see Figure 5). The WCP-1 has two circuit board locations where you can mount resistors to adjust the full clockwise and/or counterclockwise values of the resistances and thereby change the range of attenuation or voltage variation from minimum to maximum. A resistor in position R1 will add that amount of resistance to the fully counterclockwise position, while a resistor at R2 will add resistance to the fully clockwise position.

To mount a resistor in R1 or R2, first cut the printed circuit board trace at the desired location (see Figure 6). Then insert the resistor and solder it into place, and trim any excess leads.

Connections

For typical control voltage and signal attenuation applications, the CW terminal would serve as the input; the wiper terminal, as the output; and the CCW terminal, as the common.

III. WCP-2 ROTARY BCD SWITCH CONTROL

The WCP-2 uses a six-position binary-coded decimal rotary switch. It connects to two (up to four usable positions) or three (up to six usable positions) OmniPorts on the QSControl.net unit. The OmniPorts must be configured for binary use in the VenueManager application. It is ideal for such functions as selecting signal sources, selecting presets, and routing signals. The truth table is at right. For reliability of interfacing with the OmniPorts, there is no “0” position where all outputs are open.

Figures 7 and 8 depict the connection of a WCP-2 to an OmniPort.

WCP-2, WCP-1 specifications

QSC Audio has long been recognized for its commitment to delivering high-quality audio solutions, and the WCP-1 and WCP-2 wall control panels are no exception. Designed for professional audio environments, these products blend cutting-edge technology with intuitive functionality, ensuring seamless integration into various audio systems.

The WCP-1 is a compact wall panel that serves as a single-zone volume control solution. With its stylish design, it easily integrates with modern interiors while maintaining high performance. One of the standout features of the WCP-1 is its ability to control the volume of any QSC amplifier or system directly from the wall. This functionality is particularly valuable in applications where user accessibility to audio controls is a priority, such as in educational institutions, conference rooms, or hospitality environments.

On the other hand, the WCP-2 steps up the versatility with its dual-zone control capabilities. This panel not only adjusts volume but also provides the ability to switch between different audio sources, allowing users to manage multiple audio zones from a single interface. The WCP-2 is equipped with a sleek two-color LED indicator, providing visual feedback on the selected source and volume level. This feature enhances user experience by offering clear visibility, even in low-light conditions.

Both models utilize QSC’s proprietary audio control technologies, ensuring high fidelity and minimal interference. They are designed to be compatible with QSC’s Q-SYS ecosystems, making them ideal solutions for integrated installations. Offering both a line-level signal output and compatibility with other professional audio equipment, these wall panels provide robust audio performance for any setup.

Installation of the WCP-1 and WCP-2 is made simple with a standard wall plate design, allowing for easy integration into existing systems. Furthermore, both panels can be powered via PoE (Power over Ethernet), reducing the need for additional power supplies and wiring.

In conclusion, the QSC Audio WCP-1 and WCP-2 wall control panels offer an innovative, user-friendly way to manage audio in professional settings. Their elegant design, dual-zone control, PoE capability, and robust integration with QSC’s audio ecosystems make them essential tools for any audio professional looking to elevate their control over sound systems efficiently.
