Each room has a pair of speakers and amplified keypad module which offers volume and in most modules infra red (IR) control. This makes the room an independent zone meaning you can listen to a different source component simultaneously from what’s playing in another room.

Each keypad offers volume control ‘up or down’ either by rotary or by electronic format.

Depending on the level of keypads you have chosen you may select the source component from the keypad by a touch of a button. In addition, you may use the remote control pointed to the keypad to have full function of each source component, for example to change radio and paid TV stations, and play, stop or skip the CD or DVD disc.

With the IR speakers and remote, you can use the remote to control volume, source selection and source control either as a hand held remote or in its cradle on the wall.

It’s just that simple. For installations which have a Local Input Module (LIM) wallplate installed locally in a room, once you run a lead from the wallplate to the local source, and use the local source’s remote to control it for this particular room. This LIM can plug into an iPod or CD player and overrides the main source components until it is unplugged from the LIM. A-BUS offers iPod wall dock as a local source with remote control as well as a central source option.
