And for a last little rant.....there is an "engineering" design firm in the area who still spec cassette tape recorders for the school music room systems! That is always fun to explain when you are there explaining the system to new operators and they ask about why they can only record to cassette tape!


We have found (operating a school theater) that we still need the cassette player. Lots of dance studios and music teachers still make mix tapes with cassettes.

I hate having to explain to a parent why all the other acts sound good while theirs has a hiss almost as loud as the music on the track...

Now, only being able to record to cassette is inexcusable, considering that CD recorders cost about as much as cassette recorders.

Defiantly as a playback source having a cassette deck still can be a life saver, I take one out anytime I'm doing an event were the performers, participants, etc. will be music or tracks.

It is certainly inexcusable for an engineer or architect in 2009 or for that matter any time in the past 5 years or so to spec a cassette tape as the only recording option in a system.

It's good to take inventory of what you have there, but more important you need to figure out what exactly is needed to achieve the coverage required of the venue.  Simply replacing what is already there may not be the right solution.

+1 and add that response and output, and the resulting intelligibility, may also need to be considered.  I have had several football field system projects where just getting what they had already working optimally, the speakers properly aimed and then adding some appropriate processing made a huge improvement.

Also, the corners of the Press Box are typically more a compromise between what is practical and what works than being the ideal location from an audio system perspective.  And coming from someone who lives about 2,100' opposite the speakers on a high school football field Press Box, factors such as trying to cover the Visitor stands and/or the field from the Press Box can affect the system and if not handled properly may also impact areas well beyond the field.

If it's a amp-mixer you are seeking then look at TOA electronics
-This is a good series with power ranging from 60 to 240W
http://www.toaelectronics.com/amp0010.asp

Atlas makes similar units too.
-And you already have their speakers

http://www.atlassound.com/ProductCategory.aspx?id=1649&p I=1643

I think they both come with high-pass filters to keep the lows out of the horn speakers

A good place to browse and check pricing is Parts Express

I have picked up a few amps for very cheap to try. One is a Fanon Pro Power 120/120w w/4 mic inputs/2 aux inputs/EQ out & in. The Fanon was made in Japan in the 70's/80's maybe. Suppose to have very decent/low noise mic pre-amps. The other is the older model TOA 900 series amp/mixer A912A/120w that uses individual modules like mic pre-amp and aux pre-amps. Have not had a chance to go check out the equipment in the pressbox. I also bought a older EV dynamic cardoid announcer mic to try out.

Just be aware that a 120W amp will probably not really drive two 60W speakers as you will have some losses.

I still think the question that needs to be answered is what it is that you are updating and why?  The first step is probably to figure out what is there, if anything is wrong with it and what improvements or changes are required.  That includes assessing the cabling, speaker mounting hardware, etc.  Once you know that then you have some basis for assessing any new or replacement equipment.  It doesn't seem to make sense to risk replacing what is there with something that might perform the same or even worse unless the goal is to do something regardless of the result.
