At my school, our on/off sequence is controlled centrally via a
Furman PowerLink which in turn sequences 4 different
Furman PS-PRO II's, which has 3 different sets of Delayed Outlets.
Power On: Control Rack 1->Control Rack 2->
Lectern Rack->Amp Rack.
Within that, its like this:
CR 1: Wireless Mic Receivers+Mixer->CD Player+Effects Processor->DBX DriveRack 4800
CR 2: Amp for Control Room Monitors
Lectern: Wireless Mic Receivers+Assisted Listening Transmitter->Mixer->CD Player
Amp: Amp For High Frequencies->Amp For Lows+Amp For
Cluster Lows->
Stage Monitor Amp.
All that controlled via one key
switch, very convenient.
