STO Daisy Chaining
Any number of CKi amplifiers can be daisy-chained together for
sequential turn-on.Wiring two amplifiers for STO is as simple as con-
necting the “On,” “Com” and “Off” pins of the “STO Out” connector
on the first amplifier to the corresponding pins on the “STO In” con-
nector on the second amplifier.Repeating this wiring scheme with sub-
sequent amplifiers allows entire systems of CKi’s to be wired for STO.
Modules
CKi amplifiers come standard with a blank panel fixed over the module bay.
When a NexSys module is installed in this bay,connection to a network is
made via a standard RJ-45 connector and CAT-5 Ethernet cable.
Module Removal/Installation
The amplifier must be switched off and unplugged from the AC mains
supply before any module operation is undertaken.Two Phillips head
screws secure the module/panel to the chassis.The module is connect-
ed electrically to the amplifier with a single multi-pin ribbon cable.Once
unscrewed from the chassis, unplugging the module from this ribbon
cable frees the module for removal.To insert a module,simply reverse
this procedure.
