Hi,
I have a question for anyone with experience with sound systems for
meeting halls, churches, PA systems, etc.
Recently I was asked to help with repairing a sound system in a meeting
hall. My job is to solder connections for cables etc.
Originally the system was set up as:
-About 80 speakers wired in parallel. Each one has a small
transformer mounted on it. I was told that this is set up as a 70 Volt
Speaker System.
-The speakers were powered by a TOA Amplifier that had a 70 Volt
speaker output.
Here is were my question comes in. The person responsible for
installing new equipment is using the original speaker system but
hooked it up to a ART SLA 2 Amplifier (see:
http://www.artroch.com/downloads/specsheet/ART_SpecSheet_SLA2.pdf). As
far as I can tell this amplifier does not output a 70 Volt signal to
the speakers. The sound does come through, however my question is: Is
it alright to use this amplifier with this speaker system? If not, how
can I present evidence to the person in charge in a convincing way?
Thank you all for your help.
