Difficulty Level 2
  1. Great kit! review by John on 3/11/2017

    Was tasked with showing visual real time audio in police interview rooms. Hooked up two of these running 3 wire 22 ga. audio cable with drain/shield ground. Concern was length of run coming out of audio amplifier, no problem with distance! Ran 25 and 15 feet audio cable and hooked these up using the low input on board. Works like a charm! Tech support was great too! Easy to build and easy to install in standard electrical box!
