CONNECTIONS-
Stereo or Parallel Modes
Stereo and Parallel modes
use one cable for each
channel. Each cable con-
nects to its respective output
connector and speaker.
CH1's Speakon can be used
with a four conductor cable
for carrying both outputs.
The required signal splitting
would take place at the
speaker-end of the cable.
Bridge Mode
Bridge Mode Speakon connection uses CH1's Speakon only. Pin 1+ is the positive signal and Pin 2+ is the
negative signal. NOTE! Make sure the speaker-end is wired according to its specifications. The diagram
below assumes cabinet to be wired pin1+ and pin 1-. Verify proper connections are made!
