Called in today to fix a problem with someone else's installation.
The problem was the sub intermittently dropping out. At first we through the speak on connectors coming out of the amp were to blame, the more I messed around back there the worse it got, now I was losing the tops for the main set of speakers (being a restaurant, there were a couple of other zones that were unaffected by this problem). The sound would work fine until we closed the amp cupboard door at which point it would drop out entirely. After a while I realised that the problem was loose RCA connections coming out of a buzz box inserted between the PC and the zone controller. I tightened those up as best I could without a shifter spanner and that seemed to fix it. All sounded fine at low volumes, some of the zoning was weird (little restaurant speakers on the same zone as the main PA speakers) so I changed that, some of the outputs on the zone controller appeared to be going nowhere, either to second inputs on bridged amps, or inputs on a behringer ultracurve that, according to the internal routing, and the 2 cables plugged into outputs were also going nowhere. Every cable that seemed redundant I pulled out.
I made one other change so they could get better quality and volume from a remote sound source. Instead of running the PC in stereo through the buzzbox, I dropped one side of the stereo image so I could use the other side of the buzz box for the remote sound source (previously running through one of those little car audio cylinder buzz kill things). I got improved volume from my remote sound source, and the main speakers appeared to be working well with the PC when I left although it never got tested at volume.
My client thinks it sounds weird now, pressed for further description he said it was 'thin'. So, I'm wondering a couple of things, could this be because I abandoned half the output of the PC? Could it be an issue with the ultra curve? Could it be to do with the speakon connections (which I'm still suspicious off because, instead of being speaker wire, they look like this picture here.) Whoever did the installation twizzled some standard speaker wire onto these hooks in order to attach the speakon connector.
