Connecting Two Or More Pa Systems In Series - Omnitronic PAM-70 User Manual

7.3 Connecting two or more PA systems in series

For larger indoor PA applications where the sound has to be radiated as even as possible, two or more PA
systems may be connected in series. For this connect your signal sources to the primary unit and connect
the line output [LINK] to the adjustable line input [AUX] of the first secondary unit. Connect further units
likewise.
If no other signal sources are needed besides one Portable microphone, the PA systems do not have to be
connected. The microphone signal will be transmitted to all PA systems via radio.
