Electrosonic Rockboard

Christie Lites Toronto museum

Electrosonic Rockboard, 36-channel version. They were available when I started out in 1981.
You could also get a 48-channel version and an additional preset "bridge" that sat at the top of the console. It had 4 or 5 pushbuttons per channels to select/deselect.
All pin matrix memories, not a microprocessor in sight...
Output through 8-pin cannon EP connectors (6 channels per connector +10V control).

Diode pin matrix under faders and with yellow pins you choose which channel is connected to which submaster and red pins to choose which channels are connected to chaser.
Two presets and A-B-C switches per ch/ per preset (thats is why 3 green and 3 red masters).
Pictured desk has "new" submaster flashes because original ones are similar to master bswitches: heavy duty and you needed strong fingers to use those.
After heavy metal festival you knew if you have tried to get all musical hits... ;c)

There was also a 60 channel version of this made. I know this as I own one as part of the NEET collection in the UK. - Jason Williams, www.neetproject.org
