Question:  Can I get information on how the 4-wire connectors work on the HelixNet HRM-4X?  I am hoping to use those to connect broadcast camera CCUs to HelixNet Comm with out having to put another full power supply in the rack.
Answer:  Yes 4wire connections on the Helixnet Remote station can be connected to a 4wire CCU unit
The Program In / 4-wire input and SA out / 4-wire output 3-pin XLRs can support balanced line level audio to a camera CCU.  The pin outs are shown below:








SA / 4-wire line out (3-pin male XLR).
Pin Function
Pin 1 Ground
Pin 2 + Audio
Pin 3 - Audio

Program Input / 4-wire line input (3-pin female XLR).
Pin Function
Pin 1 Ground
Pin 2 + Audio
Pin 3 - Audio
See other solutions for the pinout of the Helixnet 4wire module

Program Audio will appear on PGM for the HRM-4X locally. The audio can be assigned to a channel and shared to other stations with the same channel assigned (controlled by PGM volume control).

In the Roles section of the CCM, select a HRM-4X Role. Under Program Input, use Channel Assignment to share the audio with the selected channel.

SA / 4W line out audio can be assigned to a channel.

In the Roles section of the CCM, select a HRM-4X Role. Under Stage Announce, set the Mode to Channel Assign and select a channel. All audio on the selected channel will be output from the HRM units SA out connector.
