The real jukebox is actually rather more complicated than the previous pages would suggest. I've tried to keep my descriptions simple and concentrate on the essentials. This page describes some of the additional features which have been left out.
The remote control, being a web page, can be used on devices other than the iPad. It can run on a desktop PC, or on an iPad Touch, or on an iPhone. The iOS version provides just the essentials rather than the full remote facilities (see illustration, right).
The jukebox is actually available in four different rooms. Most "multi-room" installations allow you to listen to different things in each room, but that's of no interest to us, and all the rooms get the same music.
Each room has its own remote control (one iPad, one desktop PC, and two iPod Touches). Two of the rooms have iPad monitor screens. When music is played with one remote, the other remotes and the monitor screens update immediately.
All four amplifiers are fed in parallel from the DAC outputs.
One room is difficult to get audio cables to. The audio signal goes over CAT5 cable with a balun at each end.
The monitor display has been enhanced to display additional information. What started out as a simple "what's playing" display has gradually developed into a more comprehensive information centre.
There is a small area at the bottom right which shows the date, the weather forecast from the BBC, and entries from our Google Calendars. There's one line for today and one for tomorrow.
Whenever there's an incoming phone call, the caller's number and (if known) name are displayed prominently in the middle of the screen.
When there's no music playing, the monitor screen shows random shots from our photo library, changing every 30 seconds. The photo files are stored on the server hard drive, with the music.
