Title: Does the K4900 series monitors use an isolation transformer Post by: jjohnston2004 on September 27, 2014, 06:54:34 pm Hello all,
I picked up a Moon Patrol conversion cab running a jamma board (Dj Boy). I noticed the cabinet currently has an isolation transformer that it seems to be not wired to use. If anyone has experience with the K4900 series monitors, do you know if it needs to run through an isolation transformer? Thanks, Jj Title: Re: Does the K4900 series monitors use an isolation transformer Post by: P-feif on September 27, 2014, 08:20:47 pm Here's a link that someone else gave me. It's a WG 4900 manual.

You could ruin the monitor if it doesnt have isolation.

Amazing! Thanks Again |
