CONNECTIONS
IM1 is a 2-slot 500 series module with stereo input, stereo output and stereo
insert send and return.
When installed in a Zähl Rack500 a dedicated rear panel provides all connec-
tions (8 XLR connectors).
As the 500 series standard provides only one balanced I/O per slot, the en-
closed additional breakout panel with 4 XLR connectors is needed to operate
IM1 in a standard 500 series rack - requiring one additional slot. Please read
installation guide below.
