Operating instructions
Important!
As mentioned previously, the WCU330 can be switched between two modes of operation –
a standard A-BUS
®
mode for compatibility with other manufacturers’ A-BUS
®
Ready
equipment (Standard A-BUS
®
/Opus 500 mode) or when used as a sub-zone keypad in the
Opus 500 System, and an Opus MCU300 hub mode (Opus 300/enhanced A-BUS
®
mode).
When used with other manufacturers’ A-BUS
®
Ready equipment, the keypad must be
switched to ‘Standard A-BUS
®
/Opus 500’ mode or the equipment will not work.
Volume adjustment
Volume is adjusted using the volume up and volume down buttons on the keypad or
remote. This is indicated on the keypad by the intensity of the blue LED lights, of which
there are four levels of intensity.
Source selection
The Source left and right buttons allow you to choose from multiple connected sources.
The LED display will indicate which source is selected.
Sound adjustment modes
Pressing the Power/Standby button while holding the Volume down key activates the
sound adjustment modes. The four central LEDs on the keypad will then light in sequence
to indicate each of the four sound adjustment modes: Bass, Treble, Balance and Fader.
These modes can also be activated using the Select button on the remote control.
After holding down both buttons for a short period, the second LED on the keypad will light
indicating that the Bass adjust mode has been activated. In this mode, pressing the
Volume up or down keys will adjust the bass (low frequencies) level.
