Three Rivers District Council quoted £25,000 to replace PA system

A new £25,000 microphone and speaker system for Three Rivers District Council chamber is needed to replace the current failing equipment.

The PA system in the Penn Chamber was bought in October 2002, costing £27,500. The microphones have since come to the end of their life, despite the rechargeable batteries being replaced in 2010.

Problems have occurred at a number of recent meetings due to batteries constantly being charged and used.

Leader of the council, Ann Shaw, described the current system as "embarrassingly inadequate" at an executive meeting last night, during which time the microphones frequently turned off until the system was abandoned completely, forcing councillors to talk loudly.

The council has allocated £25,000 from the capital programme to replace the system.

The existing supplier has provided two quotes, one to upgrade of the existing "swan neck" system or to replace it completely with new "Revoluto" units.

The swan neck system will replace like with like and is cheaper, costing £25,998 in total, with each microphone costing £649.75, compared with £1,084 with the Revoluto system, .

However it is susceptible to damage and the rechargeable batteries are less reliable than Revoluto units.

The Revoluto microphones are more robust, have a longer battery life, and are more sensitive, meaning they can be used by two members, but costs £36,420.

Opposition leader Chris Hayward said: "I'm surprised we've only gone to one supplier for quotes, there are a plethora of different systems that councils use across the country."

A third solution, a fixed hanging microphone system similar to the one used in the House of Commons, would cost an estimated £33,655.

The advantage is that it would be fully wired, eliminating the need to recharge the microphones.

The council agreed to put together a working party of group leaders to make the decision.

Liberal democrat Sara Bedford added: "This isn't really a choice, one is too expensive and the other is too useless."

I have not seen the council chambers, but I would guess they are not that big. £25k for a PA system seems very excessive, and as the Microphones do not need to be moved there is no need for them to be wireless or have batteries.

It's amusing that this item was of more interest to the Executive Committe that the allocation of the secondary school site on the horse Field in Baldwins Lane. This is where TRDC priorities lie-and for it to actually be regarded as news??!!

It is untrue to say that this was 'of more interest to the Executive committee' than the school sites. The school sites debate had already been held at length in June, where more information was requested. A small working party met a fortnight ago to consider new evidence and receive some new information.

We then returned last night to decide effectively that there was no alternative to what we debated in June and that sadly we had been unable to change HCC's view on the need for two school sites, one in Mill End or Maple Cross and the other in Croxley.

The microphones issue was the first time (and hopefully the last) that the committee will debate the issue.

In any case we spent longer discussing the schools policy last night than any other subject area. An immense of time, both inside and outside the council offices, has been spent on this subject, as befits its importance to residents for a number of reasons.

@rover If you had seen the council chamber, you would realise why we need a movable system. The council is deliberately designed without fixed furniture or layout, which enables it to be used for lots of different types, sizes and layouts of meetings.

Most councils have a series of different rooms for different meetings, which each need a different microphone set up.

We have however asked for more systems to be demonstrated to ensure we get something that does its job at reasonable cost.

I too have not seen the council chamber. But I have attended many a music and drama play in a large hall, many a quiz night, many a concert or recital.
I think the last time I attended anything that spent over £25,000 on a sound system was a Status Quo concert, and as I was in about the third row, that was pretty wasted on me anyway.
There are cheaper options. £25k is more than a nurses salary, and I know which I'd rather have.

If you can find a cheaper option, I'm sure Three Rivers will be very pleased to hear about it. Please send the details to the Chief Executive.

Just a quick search and you find this for £25- look very similar to what is in use already so why the £25000?

I'd be happy to for a small consultancy fee. Just using Google gives 114,000 results for PA systems, and 90% are under £1,000. 50% are under £500.
They vary from 150 to 500 Watts and beyond, which is enough to mash your eardrums.
Don't councillors have Google?

First thing you need to understand that this is not a wired system. It is all radio, with each mike individually turned on and off by each councillor. This avoids many mikes all being on at the same time and causing feedback problems. A £500 system wouldn't even come close nor would status quo's 50,000 watt PA system. Council systems of this type have feedback rejection and other circuits which stop feedback ( which is a physics problem ) . Just fitting a wired system is not the answer. The system used in the houses of parliament has hanging mikes which feed the radio and TV systems plus very low output speakers fitted into the back of each seat ( the two little rose shaped things you can see on telly). This sort of system wouldn't work at TRDC. Systems of the type specified are very expensive so £25k is understandable. However, it seems that it's the batteries which are the problem where they are suffering from memory effect problems, eg not getting a full charge as the batteries are stuck at a low voltage. Simply run them down to 0 volts and then recharge to FULL power or buy new ones. Batteries like these have a life of 2 to 3 years.

Thanks @guitarman for that helpful addition to the debate. I don't have a high level of technical knowledge, although I do no more than to simply Google everything.

Having a wireless system gives its own problems in terms of ensuring the robustness of transmission. With the previous system, we sometimes picked up taxis and also occasional performances from Watersmeet. Maybe pleasant, but not helpful if you have come to hear what is being discussed and decided. The number of digital devices carried by most of us have hugely increased and the potential interference has increased likewise.

We also need to have a speaker system, which amongst other things, limits the number of microphones which can be switched on at one time, which allows speaking in either a seated or standing position and minimises background noise from muttering councillors.

There are a number of other technical issues which I am not knowledgable about, which is why I rely on advice from council officers and others who have that knowledge.

Also we have already reduced the likely cost by keeping the number of bases at 16, rather than increasing to 24 as suggested.

Finally the batteries have already been replaced more than once and a periodic draining takes place to maintain battery life as long as possible. However there are increasing problems with the system and several attempts to revive it for longer use have failed.

Im no expert but a church I know with a large auditorium/sanctuary a couple of years ago installed a new wireless system with multiple mikes and it cost way way less than £25k.

I also know that their mikes which have a good range, can be turned on and off by the user and use rechargeable batteries cost less than £50 a peice.

Me thinks at £650 a pop the firm is taking the council for a ride. Seeing how shoddy the current system is should they really be using the same firm, there was no mention of quotes from other firms being received. Surely that is a basic thing, to hunt around and make sure you're not being ripped off

It's not the quote we would necessarily use, it's an idea of what we would need. But when we tried lesser units, we had terrible interference and feedback problems.

The only person who has come in here with any real technical knowledge seems to be @guitarman. Our own officers are checking what we need and we've already told them to come back with cheaper quotes. But first and foremost it has to work.

I have over 40years experience with PA systems. The comments made so far seem to think all you need do is buy a 1000 watt pa system and plonk it down and it will work. It will work but very badly. Any decent radio mike, a Shure SM 58 with a transmitter and receiver is approx £350. The cost of £690 approx for each mike includes the mike, the RX/TX kit,mixer amp, speakers and installation. Seems a good deal to me!

It is true that I know little of the technicalities of PA systems, but I have a degree in engineering thanks (Well 2 actually; a MEng and a BEng) so I'm not totally stumped by such problems.
However 25k is a huge amount of public money. How did they cope before wireless systems? They obviously did, councils aren't a new thing.
25k is almost exactly how much MY council reduced my charity's grant by last year.
Tighten your belts and speak up. You expect the rest of us to.

Before we had a wireless system, we had nothing that worked. Before that, we had nothing. People didn't hear Councillors. Which was fine, except people often wanted to know what was happening.

The less that cn be spent on a sound system, the more that can be pent on children's pay equipment or whatever. Councillors do not generally get some sort of illicit thrill from spending residents' money unnecessarily.

The Three Rivers part of the council tax is several percent lower than it was over six years ago. The only council that has been lower I believe the Lonon Borough of Hamersmih and Fulham. We haven't got there without some effort.

"Councillors do not generally get some sort of illicit thrill from spending residents' money unnecessarily."

I'm sure they don't. But many have been guilty over the years of mistaking their own importance.
A classic example was the special traffic lanes for the Olympics; God forbid they should be late but it is fine if a surgeon is caught in traffic, or a barrister at Crown Court, or a student on their way to an exam that might shape their entire life; none of them are as important as a man that runs 0.01 of a second faster than the man next to him. That is a very recent example that proves it still goes on.

I'm not knocking you or your council, and I'm not a resident there, but I'm just pointing out sometimes people get carried away with 'essentials' that are in fact anything but.

The Olymoic lanes were not agreed or arranged by any council. Hey had to be agreed in order for the IOC to give the bid to London (as with any host city) and I believe were introduced by Act of Parliament.

10:37pm Wed 5 Sep 12

I think you are missing my point. It was merely an example of people with the authority to spend money getting it wrong as to what, and who, is actually important.
There have been many examples of councils and politicians doing this in the past. John Prescott made a career of it, needing two company Jaguars that he didn't pay for and the right to use bus lanes the rest of us would be fined for using. He was clearly more essential to the species than you or I.

Would the council consider a £25k grant to a church, mosque or synagogue for a sound system? There are many who would argue the word of their god is FAR more important than the word of the council.

What about schools? When I was a nipper I could never hear a word in assembly in the main hall. Or is that less important?

As I said, I do not know the layout of the council chamber or the number of councilors there even are. But if you seriously cannot hear each other in one room then I respectfully suggest:
The room is to big.
Some people need to learn manners and shut up when someone-else is talking.
You have too many councilors.

Sara says...
10:46pm Wed 5 Sep 12

For Councillors, we can generally hear each other fine. It's the public that can't hear and they complain.

Would we give a grant for that amount to a club? Well we have in the past. But not for religious purposes - like Alastair Campbell, we don't (corporately) do God.
