The Neutrik Combo connector combines a XLR chassis connector and a ¼" phone jack in one housing. The result is a cost effective, space saving connector. Typical applications are line/mic inputs with independent signal amplifying. The switching contacts allow to detect the circuit of choice. The Combo is often used for sound- and video-mixers to solve space-problems, active loudspeaker systems, effect devices, portable gears, etc.
The combo is available with 3 switching contacts (NCJ9FI-*). These contacts are closed to the TIP / RING / SLEEVE of the ¼" jack, when no plug is mated. The circuit opens when connecting a ¼" plug into the Combo. We also offer an additional switching ground contact (NCJ10FI-*), which is closed to the XLR chassis ground and opens when connecting a XLR cable connector.
No. To achieve this you have to bridge XLR and TRS contacts on the pcb or terminals.
