DSP suggestion for older PA
« on: February 10, 2023, 01:48:06 PM »

I had a failure two weeks ago of a client's old BSS 9088iis DSP in a drive system feeding a cluster of individual JBL components and Yamaha amplifiers.  This is at a church install from back in the 90's(?) with about 2000 seats.

In researching new options, I'm not finding anything that is a great fit.  I know a lot of line arrays and current speakers have their own proprietary processing in today's world and that will be fine for the new system. But I'm looking for something today to bridge this gap. This system has a total of 5 inputs and 11 outputs for the mains.  It's currently running on their backup of really old Yamaha D1030s using analog I/O, PEQ, HP, LP, Crossover, and some Delays per output. 

Any suggestions for a temporary replacement, while a new system is being designed, funded, and installed?  Looking for something mid-range in price and reliable till a newer system can be purchased.  I've considered a pair of Lake LM44s (not sure will hear the benefits to justify the cost given other components in this system), Meyer Galaxy (too long lead time and costly), BSS London BLU (not my favorite interface), QSC Q-SYS (seems complicated for basic DSP functions), Biamp (eh?), Ashley Protea SP series (hard to control remotely on 3rd floor amp room but functionally seems ok), multiple DBX drive rack (there's got to be a better option than trying to tie 4 of these together)...other options...what am I missing in today's products? 

What's your favorite go to box for a situation like this? Thanks for any suggestions!

Do you have the original Sound Web file?  Certainly if so, get a used 9088 ($150-$200 e-bay) to tide them over.  Cheap and performance they are familiar with and won't think "Oh, my gosh this sounds so much better, maybe we don't need to upgrade."  :-)

If you can't find a used BSS 9088, and want things in a single package find a used Ashly NE8800 and add an additional output module if needed.  You will have to make up the cables, which is easy as they have Euroblock connectors on them.

Sadly, I do not have the original files as I did not do the install and the original company no longer exist, but yes, that's a good thought.

What was the failure mode on the 9088? These units are known for having capacitors fail in the power supply section. Perhaps having a qualified bench tech look at it and replace the PS caps (it may be even just one capacitor that's failed) will get you back in business with loads of time to design a new system.

I'll look into this model. I feel like Ashly is probably inline with this system, just need to be able to remote control it for setup and this might just work. Thanks!

I'm not sure of the exact failure, but it still has power and shows input, just no output. The primary Yamaha M7 console also failed with all analog I/O.  All digital slots still work and the Aviom and Cobranet I/O still works, but the analog on both units failed, which was noticed on a Saturday night and resulted in an emergency midnight service call till 3am Sunday morning. Fun times trying to figure out what happened.  No power surges that we are aware of as of now.  Ironically, the operator likes the additional headroom using the old Yamaha D1030s vs the processing that was setup in the Soundweb....I could open it up and replace the caps, but given the age of greater than 20 years and not having the original files to re-compile, I'm thinking the time spent is best used re-tuning the system with a more current product.  Hoping the system is replaced as a part of a larger technology upgrade, but that will never happen soon enough, as we all know...

"NE" means Network Enabled.  They have an RJ45 port on the back and works well on ethernet interface well with static or dynamic IP addressing available.

The control application runs well and is very easy to use.

Those descriptions would have me looking at the power supplies and any bipolar 15-18 VDC supplies that ran the analog stages. These could be a relatively cheap fix compared to replacing a large format console and a new DSP with it's attendant wheel reinventing.

I'm not sure of the exact failure, but it still has power and shows input, just no output. The primary Yamaha M7 console also failed with all analog I/O.  All digital slots still work and the Aviom and Cobranet I/O still works, but the analog on both units failed, which was noticed on a Saturday night and resulted in an emergency midnight service call till 3am Sunday morning. ...
