1. Audio setup

2. Loudspeaker setup

The global system consists in:

• PA System: 1 stereo system type L-Acoustics or equivalent. It must installed by a professional PA company so the design is adjusted to the venue for the best coverage in the public area.
• Surround: a set of speakers placed around the audience and technically able to cover the audience area (the blue loudspeakers in the following plan). 6 loudspeakers minimum are needed. According to the venue, some extra loudspeakers could be needed in order to cover the audience area. Ideally it would be a 12 inches point source speakers (L-acoustics X12 or D&B E12).

Beware that amplification, EQ and Delay must be independent for each speaker.

• Subwoofers: a subwoofer system, to cover the low frequencies of the PA system.

In addition to this setup, a speaker complement could be needed in case of particular acoustics conditions (f.ex front fill, extra-speakers on balconies). These choices have to be discussed with IRCAM Sound Engineer

3. Midi setup

1 Asparion midi controller. Preset file provided LiveRobin.aPres. Any midi controller with at least 11 controls will fit but you will have to reconfigure the midi mapping.

4. Software installation
