12.6 3-D decoder with optional "energy" or diametric opposites matrix, software crossovers, and distance compensation delays.
Speaker layout for 12.6 system in Meany Hall
Speaker layout, both jpg and psd. Note ideal locations vs. actual locations. Speakers were moved for obstruction reasons as well as the lower laterals shifted for the "push/pull" decoder so the upper laterals and lower laterals are pointed at each other through the sweet spot. This shift need not happen in a 2-D arrangement (only the lower rig). Power is also indicated to avoid buzz and aisle obstructions.
• 3D ambisonic setup, 12.6, tape music only, with Crossovers (no microphone/line inputs)
Signal routing & Mixer setup (Using the Behringer Crossovers)
The schematics below were initially created for the 26 Oct. 2010 concert (Joe Anderson).
Here is the OmniGraffle file, in case the above schematics need editing:
Signal routing & Mixer setup (Crossover within SuperCollider)
Special cables needed for routingAll routing happens via TDIF (Mixer > RME converters), ADAT (RME converters > Apogee DA converters), then analog XLR out from the breakouts from the Apogee DA16X or Rosetta to the speakers.
For independent fader control of the subs:
This requires routing the sub channels from the Behringer crossovers into the analog ins on the Rosetta, out to the mixer via ADAT, [into the mixer via group-able channels, routed to busses, busses routed to ADAT out], back to the Rosetta via ADAT and and our the analog outs to the subs.
Hardware Crossover configuration and speaker routing
The crossover settings and configuration for a 12.6 setup (initially created for the 26 Oct. 2010 concert, Joe Anderson).
And the OmniGraffle file:
(for some reason I cannot attach the file with the Meany layout, so this is a simplified version. If you need the file that made the above .tiff image, contact steliosm [at] uw.edu)
Special cables needed for routing (with crossovers)
- 3x TDIF cables (should be long); we also need backups
- 4x ADAT cables (3 short, one long)
- 2x XLR breakouts (1x12 chan for DA-16X to crossovers, 1x6 chan for crossovers to Apogee Rosetta; current setup is 2x8 channels)
- 6x word clock
- 1x long Firewire (computer to Tascam)
• 2D ambisonic setup, 6.3 and double stereo (with microphones and lines):
The below configuration was used in the FALL 2008 concert
