The WCU330 is an in-wall, A-BUS
®
compatible amplified keypad with buttons for control of
speaker volume levels, Standby/On and source select (with compatible equipment), as well
as having an IR window for receiving remote control signals. The WCU330 can connect to
A-BUS
®
hubs (Opus MCU300), A-BUS
®
Ready receivers, or to the Opus 500 system as a
sub-zone control. The WCU330 then connects to speakers using conventional speaker
cable.
The WCU330 keypad fits into any wall and is available in white and stainless steel finishes,
with the ability to change the surrounds on the WCU330-WH with any MK Euro/Modular
surrounds, to complement various decorative schemes. The WCU330 is fitted to the wall by
fixing it into a standard single UK 47mm back-box. All knock-outs in the back-box should
be removed to provide maximum ventilation. Care should be taken in choosing a site for the
WCU330, and always refer to the precautions in this guide. Bear in mind it is not always
preferable to fit the WCU330 next to a light switch, particularly if the faceplates will differ.
