Sound system for old village hall

cynic · 2011-10-02T19:32:35+00:00

Hi to any sound engineers with long memories. I have recently joinedthe committee of our small village hall (East Yorkshire) and noticethere are a number (6 in the large room and 1 in the smaller room) ofloudpeakers mounted around the walls in wooden cabinets. No one on thepresent committee knows anything about them but I have discovered thattucked away at the side of the stage are a similar number of cableswith approx 20mm screw collar connectors just where an amplifier mighthave been situated. Without creating decor damage to look inside thespeaker cabinets I am planning to test if there is continuity throughthe leads and speakers and hope maybe the meter will providesufficient current to hear if there is an audible click speakerresponse.My problem then will be to try to guess what kind of amplifier mighthave been present. I don't think it would have been a stereo systembut probaly used for stage microphone(s) and playing music via an oldfashioned record player and hence my question here is - has anyone anysuggestions what makers names I can google for?

Yeah that's a common connector for 'fixed-install' sound equipment, the scalloping on one side is the distinguishing feature, don't know what they're called though, as the stuff I work with (live music for churches) is the transportable type with robust 'Speakon', 'XLR' and 'jack' connectors. I have seen them on outputs from induction-loop amplifiers (for hearing aids), but they can be used for all other types of audio and control circuits.

This book is very good, all you need to know about speech PA systems:

The connector is made by 'Phoenix', and is a common type of connector on the speaker outputs of amplifier intended to drive 100V speaker lines.

RS and Farnell sell, them, but measure the pin-to-pin distance accurately, as there are many size variants that are difficult to distinguish between on the catalogue page or web site screen!

Blimey. Is that your bedtime reading...

..I know I had memorised the general specs on about 1000 transistors at one time..

I thought so too except molex are generally white polyythene..it might be Amphenol.

I think that fits with the statement in the manual that its a screw connector - looks like that female bit should have been there with the amp,. and its missing.
