PERFORMER Digital Partyline, User Manual, Version 2.30
7 PERFORMER C31 SPLIT BOX
The C31 is used to create splits in the digital partyline. The audio signals are processed
entirely digitally by DSP chips. The C31 is normally powered by the digital partyline.
With its external power connector the C31 enables the insertion of additional power (optional
C31 PSU) into the partyline to compensate for power loss due to long cable runs. It is
recommended to power each C31 in complex installations with long cable runs or many
digital partyline devices.
The C31 has one upstream and three downstream connectors.
Note: Even if the additional external power supply is not used, all three downstream
connections are still powered by the single upstream line.
