Re: I Guess I'll Start This Off
Here's a couple more installs that make you ask what are they thinking!
About 10 years ago I was in a cities new government building as the installers were finishing the AV install in the council meeting room that consisted of four small JBL control series speakers, goose neck podium mics at each council members seating position, mic for audience questions and play back inputs. I watched as the installer carved out the biggest, deepest smiley face I have ever seen on the system 31 band EQ's. Not to let that go without comment I said "that's a low frequency boost for those speakers" his answer was....."we let the feedback eliminator take care of that"
More recently I was looking over a new school building for a school district that I provide audio production for at their Christmas and spring concerts while the install company was doing the training on the system in the gym. Upon turning on the power sequencer for the system I was hearing all kind of pops and cracks as the system powered up as well as when they powered it off. When the system was on I walked and listened to the three speakers covering the bleachers and thought there was a big such out cancellation between the speakers. Looking at the rack I noticed first that the power amp was plugged into sequence position #1 and the power amp was in bridged mono mode but wired for normal stereo output with two pair of speaker lines on one output and a single speaker line on the other. I commented to the installer about the popping sound during power up and down with the power amp plugged in the first position on the sequencer, his comment was that the system DSP had not been fully adjusted yet and that would take care it!!!!!! Yes he said that!.
As for the bridged mono power amp, he said the system is mono with just the three speakers, I tried to explain about one amp channel polarity being inverted causing the suck out between speakers and the amp should be in stereo mode and use the input "Y" switch on the amp, the amp is a Crown CTS series..deer in the headlights is the best way I can describe his response. I won't even go into had bad the school music rooms were configured and they were complaining about the problems in the music rooms.
Both of the above install companies are doing installs as you read this, they are large companies, neither of the installers were 18 year old summer either.
I did offer the school to take care of the issues and bill the contractor for the service call, being still under warranty the installer was going to take care it I was told.
Rant over!!!!
