8 PERFORMER C44 / C44PLUS SYSTEM INTERFACE
The C44 / C44plus drives up to 4 partylines. Through the integrated 2-wire/4-wire converter
it enables digital connections to an Artist/Performer matrix intercom system over a CAT-5
cable using the Artist I/O ports. In addition, the front of the unit has eight analog ports where
the partyline audio signals can be accessed. Using these analog ports or the AES (Artist I/O
ports), the C44 / C44plus System Interface can be connected to other third-party intercom
systems.
8.1.1 Get Started
Connect the C44 / C44plus System Interface to power. The 4 LEDs next to each 3-pole XLR
connector, as well as the DC INT and DC OK LEDs will light up green.
Connect the first device (e.g. C3 beltpack) to the C44 / C44plus System Interface with a 3-
pole XLR cable. The power LED on the C3 beltpack should light up red. Now connect the
second device to the “Downstream” connector on the first C3 beltpack and so on. You can
connect up to a total of 16 units in a row per partyline.
In order to prevent interruptions of the audio signal, keep the cable length as short as
possible. Make sure that all connectors are securely attached to the C44 / C44plus. Poorly
secured connectors lead to static in the audio system and can also cause a reset of the
entire partyline. If a large number of devices are operated on a single partyline a large drop in
voltage may occur, depending on the ohm resistance of the cable used. In this case, the
voltage can be boosted by adding of other powering devices, such as C31+PSU.
Note: If three or more devices are connected per port to the System Interface, a 1RU space
between the C44 / C44plus and other equipment should be allowed when possible to ensure
adequate ventilation.
