CAB-MIC20-EXT Plenum Rated?

[schue0001]

Does anyone know if the CAB-MIC20-EXT extension cable is plenum rated? If not, does anyone know of an equivalent 3.5mm TRRS pre-made extension cable that is?

Hello -

We don't have any plenum rated cables in our price list. The best bet is to make up a plenum-rated cable using 22 gauge, 4 conductor, sheilded audio cable. Put 4 conductor 3.5mm connectors at each end.

Hi Schue,

We ran into the same issue. We ran a standard 4 conductor plenum shielded audio cable (liberty cable) and terminated with Sound Control's RM-P20 Microphone Adapter, which worked perfectly.

Here is the cable we used:

22-4C-PSH-WHT - Commercial grade general purpose 22 AWG 4 conductor plenum shielded cable

Here is the adapter:

Thank you,
