Telex PS-20 Reviews

Expensive but functional

Has a semi-loud fan in the front. Does typical intercom stuff and has the rock solid performance you'd expect from RTS including the ability to do 2 channels of clearcom.

What is the maximum cable distance you can run for a 40 belt pack system?
Asked by: Phil
Thank you for your question. The max amount of belt packs i would recommend on a PS-20 would be 20 with a cumulative cable length of 1000 FT. To run 40 packs i would recommend using two (2) PS20 power supplies using the TRS audio coupler in the back of the unit.
