C-Bus Control and Switches

The most common method of controlling an MRA amplifier is with a

C-Bus Saturn, Neo or Dynamic Labelling Technology (DLT) keypad.

Buttons on a C-Bus keypad can be used to control the volume/on/off

(combined), bass, treble and muting. The figure below shows a

possible control configuration for a Saturn keypad. The top two

buttons control a light and the remaining buttons control audio.

A. Light ON/OFF

B. Muting ON/OFF

C. Bass +/-

D. Light ON/OFF

E. Volume +/-

F. Bass/Treble +/-

Volume buttons are typically multipurpose. For example, a

quick-press can toggle the amplifier between On and Standby. A

long press (of more than 400 milliseconds, about one half second)

adjusts the volume. This action may vary depending on how the

installer has configured the system.

Other C-Bus devices, such as the Color Touch Screen, can provide

control for a MRA system or standalone amplifier. The touch screen

can be used to control an MRA amplifier according to a schedule.

For detailed information and programming instructions, refer to the

installation instructions for the keypad or touch screen being used. A

C-Bus installer can create a custom control configuration based on

the customer's requirements.

An installer can configure an amplifier to be controlled by a IR

remote control (SLC5035TX). The IR Remote Control is used to

control the touch screens. The figure below shows typical button

assignments used when an amplifier is configured to work with this

type of remote control.
