adamburns Posted September 12, 2008 Share Posted September 12, 2008 I am wondering if anyone knows the answer. Regarding the senn ew100 g2. I want to know how many of those can I run together at once without problems, ideally say 10-or would this need a better bit of kit. Cheers.

Bobbsy Posted September 12, 2008 Share Posted September 12, 2008 How many licences are you willing to pay for? In the free spectrum you can only get a maximum of 4 channels...a search of the BR will find you the intermod-free frequencies to use. If you pay for the £75 UK General licence you can get at least another 8 (some say more) so with this and the licence exempt spectrum you can easily get your ten.

Ynot Posted September 12, 2008 Share Posted September 12, 2008 We own 11 Senn mics - a mix of G1 and G". These are run quite regularly up to and including all 11 with no major problems. We also have access to 3 more which are brought in for major shows and again run happily alongside our own. Our licence covers us for 14 frequencies, set by JFMG in the Programme makers band (IIRC). That said, we are a small venue. Others I believe have had issues with that many mics. Link to comment Share on other sites More sharing options...
Shez Posted September 12, 2008 Share Posted September 12, 2008 I've used 12 of the shared (ch.69) frequencies with G2s before without a problem (500 series but the RF side is supposedly the same as the 100 series). Only one of the deregulated frequencies will play ball with them, so you should be able to manage 13 in total. Use an antennae distro to keep things tidy and avoid any RF problems.

ph507 Posted September 12, 2008 Share Posted September 12, 2008 I've ran 20 of the 300 series together using the frequencies listed in the 'additional information' leaflet supplied with the mic's. Had no RF problems at all and 8 of the receivers were just using the supplied antennas. Link to comment Share on other sites More sharing options...

Light Console Posted September 12, 2008 Share Posted September 12, 2008 We have 15 of them, all licenced, all working well. We have two shark's fins, one under the front row of seating, the other up in the gods above the acoustic baffles. The only problem we have is when the costumes have metal sequins. Recievers are fed from 3 ADUs, up in the control desk, which makes fault finding easy - "Tell Doris to turn plug her microphone back into the pack again!" I believe this cost the best part of £15,000 with install, 6 HH and 15 BP transmitters with ME2s and 6 headsets. Edit, just to add these are G2 EW500s.

Bobbsy Posted September 13, 2008 Share Posted September 13, 2008 As we're talking about real-world experience, I've frequently used 12 channels on the UK General licence with no problems at all...the only reason I mentioned 8 is that is what Sennheiser themselves claim, saying that the 300s and 500s will do more. Probably part sales pitch and part that the filters on the 100s are on guaranteed to a certain spec but generally perform better. I too would like to hear the licence arrangements made by the poster who says he uses 20. Using 20 is no issue--it's just paying for the licencing to expand into other UHF channels to do it.

ThomJ Posted September 14, 2008 Share Posted September 14, 2008 All this is very interesting and in some ways relevant to my question this morning. The licensing issue is a funny one (not the regs but the information). I have come across many people who are completely unaware of the licensing requirements of radio mics. Just the other week I was working with an 'Elvis' who asked if he could use his own radio mic and not the Sennheiser we had supplied for the lead vocal (more than one act on stage) I agreed and took his mic it was set to channel 1-1 which was a freq of 855.000 Mhz (I think) which of course is a licensable frequency. I asked him about the license and he said 'I asked for a radio mic that I could use in the UK' (He was American). This is the problem and I believe that users like DJs and solo acts get caught out (and probably many techs as well). The assumption is that a mic you buy retail (or trade) come pre-set to a freq that you can use and the manuals do not mention the UK licensing laws. As a result there are many people out there using these frequencies that should be licensed, completely unaware that they are liable to a £5000 fine from Ofcom. Even we had this problem, we recently purchased some 3 channel AKG Flex 40 mics for hire stock. Assumed, that as they are the cheap end of the spectrum and aimed at DJs and the like the 3 channels would be in the licence exempt range - they are not! it so happens that they are in Channel 69. On closer inspection of the info inside the box they come in a range of from A-H + ISM - each with 3 channels (ours are H) and are all said to be for use in the UK but there is no mention of the need for a licence for any of the versions (only the ISM version has the licence exempt frequencies). I know manufactures have to (for reasons of budget etc.) make mics that use multiple frequencies but how hard would it be for them to drop in a note explaining what licensing is required for their products. Thom PS (Damn this is a long post) - the supplier (a large UK distributor) of the AKG mic was a little surprised when I told him of what I had found and went running down to the warehouse to check current stocks so as not to be supplying the wrong frequencies.

Shez Posted September 14, 2008 Share Posted September 14, 2008 I have come across many people who are completely unaware of the licensing requirements of radio mics. I see this all the time too. I usually have a frequency counter in my kit bag for when people turn up with cheap mics that don't even detail what frequency they use. I've also come across people who are well aware of the need for licences but just don't bother with them. Which is part of the reason we're now in danger of losing such a big chunk of "our" spectrum - the only quantifiable measure of spectrum usage is the number of licences dished out - if everyone was properly licenced, it would be very apparent that we're using far more of the currently available spectrum than OFCOM believes. </OT rant> Link to comment Share on other sites More sharing options...
Simon Lewis Posted September 14, 2008 Share Posted September 14, 2008 - Many manufacturers do not provide UK regulated and deregulated frequency information on their website, or even in the radio mic instructions (often it's on a slip of paper).- Many offer a "scan" function... of course the radio mic has no idea whether it is 'allowed' to transmit in the "clear radio space" it's just found.- Many retailers still provide inaccurate information on their sales websites (even after grumpy gits like me tell them the information is incorrect)... e.g. a firm that sells spares to studios... "This series operates in the carrier frequency range 838-870MHz which is deregulated and can be used without a UK licence". WRONG!! Simon Link to comment Share on other sites More sharing options...
