  • Archived music from a connected NAS or computer
  • Stream from mobile devices such as iPhone

Integrate your multi-room with your hi-fi or home cinema system for superior sound quality. Play different sources in different rooms simultaneously, link rooms and create a party zone, enjoy your music wherever you are!

What are lighting scenes?

With a lighting control system, we need to think a little differently, as you want to make your smart home work for you. A lighting control keypad will have several buttons, programmed to recall lighting scenes. The homeowner decides what the scenes will be and these can be refined during the project. We like to think of scenes as being task or mood specific such as food preparation, dining, cleaning, entertaining, watching movies and reading. Pressing a single button will recall a scene.

A lighting scene could be:
• Down lighters – 50% brightness
• Wall Lights – 30% brightness
• Table lamps – Off
• LED mood lighting – Blue, 40% brightness

These changes happen concurrently and smoothly over a few seconds.

USB

Acronym for Universal Serial Bus (USB), an industry standard developed in the
mid-1990s that defines the cables, connectors and communications protocols used for connection, communication, and power supply between computers and electronic devices. Some audio devices can play MP3 tracks directly from a USB memory stick.

Sub-woofer

The speaker that produces low-frequency sounds.

Speaker systems – 2.1, 5.1, 7.1

2.1 – These systems do not use the rear and centre speakers, leaving only the
sub-woofer and two front speakers.

5.1 – Three front speakers, positioned to the left, right and centre at the front of the room, but also includes two rear speakers positioned behind the listener and a subwoofer positioned elsewhere in the room.The lower bass notes that come from the subwoofer are less directional than the higher frequencies, positioning is less critical than the placing of the satellite speakers.

7.1 – Takes the basic 5.1 layout and adds two more rear speakers. However, the majority of Blu-ray discs are only mixed for 5.1 audio so the addition of these two extra speakers has no significant effect. Some 7.1 discs are available but in small numbers. 7.1 is for those who want the ultimate system.
