New Processor for the Sanctuary

We spent the day Tuesday putting in a new processor. Why you may ask? We have been noticing the loss of high frequencies (5000Khz+) for some time and have been thinking it was the speakers. We thought it would be cheaper to change the processor first than change the speakers.

The system was not independently setup before (each speaker adjustable on it's own). We have rewired the processor so each speaker (all 6) are independent and can be EQ'd to bring out the best of that speaker. In doing all this we have discovered that the speakers are fine and know that there are a couple issues but we can work around for now. Here's what we know. The Arrays are unbalanced as a pair, but now balanced  through the processor. The Stage right speaker we will be watching. It has some issues. The Subs are falling off at around 40 cycles (not good for subs). This tells us the speakers were run at too high a frequency some time before I started working here.The Side Fill speakers are fine and running appropriately.

What does this all mean? Sound guys...we will have to reset all our EQ's for instruments and vocals. I'll work on some of those during the week so I can get the drums and some guitars in our library. Just be aware there will be more setup and listening going on.

I forgot one thing! When we first balanced everything and turned everything on for the first time...everything equal the Stage Right side was 7 db's higher than the Stage Left side. That is now corrected to within .25 db.

So, everyone please start listening to see what you hear good or bad throughout the sanctuary for the next couple weeks. Help me finish tweaking the system to what this room can do with what we have.
