pete10uk Posted June 1, 2015 Share Posted June 1, 2015 I have a 240w 100v line system and horns that I'm more than happy with. A customer is wanting to hire the system for Public Address and would like the system to chime prior to talking. I've had a bit of a look around and it seems a perfectly normal thing but I can only find it built in to amp/mixers, can anyone suggest a mixer with this function or an easy way to achieve this using the equipment I already have, maybe some sort of injector. It will be tone used with a sennheiser wireless mic so needs to lock on once the mic is activated. Cheers Link to comment Share on other sites More sharing options...
sandall Posted June 1, 2015 Share Posted June 1, 2015 Depending on its make & age your amp might already have a (disabled) chime function, or you may be able to get a chime module for it. There are lots of downloadable chime sounds, & circuits to build your own, but the easy way might be a cheap ding-dong or electronic doorbell & a mic.

pete10uk Posted June 1, 2015 Author Share Posted June 1, 2015 it’s a Pulse amp, new in the past 6 months. Don't think any of the pulse amps have a chime feature so doubt it is disabled and don't think there are any modules Should mention I'm looking for a propper solution not a hi-di-hi mock up. if needs be I'll just buy a new mixer amp with the feature built in but not 100% sure about how the latching would work. Customer doesn't want to have to press and hold a button while talking. Link to comment Share on other sites More sharing options...
sandall Posted June 1, 2015 Share Posted June 1, 2015 Should mention I'm looking for a propper solution not a hi-di-hi mock up.Point taken! I've got various Mustang & Millbank mixer-amps knocking about, & I think they all came with a (hurriedly disabled) chime feature. I even have a big old Inkel(?) amp that does a good impression of a fire-alarm when it gets stressed (not mentioned in the handbook, so came as a very nasty surprise at the big Civic function where I first met it !!). I think TOA amps may still come with chimes. Link to comment Share on other sites More sharing options...
paulears Posted June 1, 2015 Share Posted June 1, 2015 Could you not just give them a paging mic?CPC linkhttp://uk.farnell.com/productimages/large/en_GB/MP34915-40.jpg Link to comment Share on other sites More sharing options...

Brian Posted June 1, 2015 Share Posted June 1, 2015 Somewhere I *think* I've got a NOS Millbank chime module sitting in a box. I'll be in the store tomorrow; I'll have a look. Link to comment Share on other sites More sharing options...
TomHoward Posted June 1, 2015 Share Posted June 1, 2015 I may have misunderstood what you're saying, but just in case you're looking at the I don't think the InterM chimes work like that - all the PAM amps and many others have a chime button on them, but it's just a single press & chime - it's not connected to the mic switching as far as I'm aware. So you manually press the button and the PTT button separately. Edit to add - I'm only thinking of the front panel, they have external chime & muting wiring terminals on the back, so you'd wire it to a remote switch with the PTT and you wouldn't need to mess with the front of the amp.

Owain Posted June 1, 2015 Share Posted June 1, 2015 The problem is that you need a trigger from the microphone to activate the chime. I don't know any wireless microphone that takes the switching action on the microphone, sends it by radio to the receiver, and the receiver has a relay output to activate the chime on the amplifier. Using a voice operated chime wouldn't work well because the voice that triggers the chime would also be obscured by that chime. Possibly using a wireless push-button taped to the microphone to provide the momentary contact to trigger the chime, and use the latching switch on the microphone for audio on/off. The cheapskate way would be a wireless doorbell with its speaker wired through an attenuator into the PA amp line input. Link to comment Share on other sites More sharing options...

We have the interM Pam340, it has auto chime when you press the PTT and the chime ducks when you start to speak, the PTT is non latching. Link to comment Share on other sites More sharing options...

I don't know any wireless microphone that takes the switching action on the microphone, sends it by radio to the receiver, and the receiver has a relay output to activate the chime on the amplifier. I have seen this done in Asda (!), it worked off the squelch on the radio mic receiver so that when the person on the shop floor turned on the radio mic, it triggered the chime. Unfortunately it was a few years ago and I do not remember exactly what the model of radio mic was and how they got a trigger from the squelch circuit. I think it was a Trantec system. Maybe they do a special receiver for Asda... Link to comment Share on other sites More sharing options...
david.elsbury Posted June 2, 2015 Share Posted June 2, 2015 Maybe the chime is keyed off the "I'm receiving RF" LED on the receiver? That's what I'd do anyway :) Link to comment Share on other sites More sharing options...

pete10uk Posted June 2, 2015 Author Share Posted June 2, 2015 Morning all Thanks for your replies. Think this may have been taken too far here. What I'm after is a system that can play a chime when the microphone is wanted to be used. The customer has no issue with pressing a chime button as imagine the interM stuff works, and then walking away from the desk with the wireless mic. What would be ideal is what Paulears has suggested, but only if the button is latching. As a close second would be the same chiming base on a second channel so the customer can press the button on a channel which is permanently up and have the mic up on a second channel and just use the mic mute. The advantage of having a latching button on the base is it is just a 1 button press solution, but thinking about it if the mic is on a second channel the customer can always choose to unmet the mic remotely without the chime and without having to return back to the base to activate the chime and audio. Thanks Paulears, I think the has solved the issue. Cheers Link to comment Share on other sites More sharing options...
