L7NirvanaLove Posted May 5, 2015 Report Share Posted May 5, 2015 Has anyone bought SMDB's and what's the main difference between them and smqv's and smv's. I know from the lectrosonics website smdb's are sold in the UK and Europe? I was wondering if there would be any problems operating them in the US and is any one has or is currently using them in the US? Thanks Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted May 5, 2015 Report Share Posted May 5, 2015 I think the "V" was for variable power, and maybe more. The later versions of the "V" models added a backlight, but not all of them. Only 1 of my 5 SMQV/SMV transmitters is new enough to have a backlight. Quote Link to comment Share on other sites More sharing options...
greg sextro Posted May 5, 2015 Report Share Posted May 5, 2015 smdb are fixed 50mW output according to lectrosonics website. Quote Link to comment Share on other sites More sharing options...
L7NirvanaLove Posted May 5, 2015 Author Report Share Posted May 5, 2015 Yeah I seen in another post that the 50mW isn't a huge deal other then that you need to bump up the gain a bit. Would the fixed 50mW be a very noticeable? Quote Link to comment Share on other sites More sharing options...
bmfsnd Posted May 5, 2015 Report Share Posted May 5, 2015 50mW is output power of transmission, unrelated to microphone gain. Quote Link to comment Share on other sites More sharing options...
L7NirvanaLove Posted May 5, 2015 Author Report Share Posted May 5, 2015 Understood. Thanks Matt. Quote Link to comment Share on other sites More sharing options...
capese21 Posted May 15, 2015 Report Share Posted May 15, 2015 My UK bought smdb's will switch to 250mW. Sent from my KFTHWI using Tapatalk Quote Link to comment Share on other sites More sharing options...
Derek H Posted May 16, 2015 Report Share Posted May 16, 2015 I think SMDB were the first double battery version available after the original SM and are fixed at the standard 100mW.. Different from SMQa version that were fixed at 250mW. Q being for "quarter-watt". ...I think... Clearly we need a Lectro rep to clear this up.. Or someone needs to call. Last time I had them on the phone I'm pretty sure they told me it's 100mW. I own one, bought it used, and was trying to confirm just that. Maybe it depends on the country it was sold in what output power the SMDB runs at? Quote Link to comment Share on other sites More sharing options...
JDirckze Posted May 16, 2015 Report Share Posted May 16, 2015 And over in Australia we have the SMDa/au, which are fixed 100mW I think. I also have a couple of the SMQa and yes they are fixed 250mW and run super hot, and go through batteries quick! Quote Link to comment Share on other sites More sharing options...
marcvonstuerler Posted May 16, 2015 Report Share Posted May 16, 2015 SMDB/E01=SMDA but for EU Market, max. oP fixed at 50mW, no backlight, older models have fixed antenna. Quote Link to comment Share on other sites More sharing options...
axel Posted May 16, 2015 Report Share Posted May 16, 2015 SMDb is the current european version of the SMQV. It is limited to 50 mW output power. I think it is fully compatible with US Versions of any 400 mode Lectro receivers. But don't use European receivers with US type transmitters, that combo is not fully functional.

Derek H Posted May 16, 2015 Report Share Posted May 16, 2015 And over in Australia we have the SMDa/au, which are fixed 100mW I think. I also have a couple of the SMQa and yes they are fixed 250mW and run super hot, and go through batteries quick! Anything marked AU is actually 50mW output. But it depends who's standard you're going by... From what I understand the way the Australian regulators wrote their rules 100mW radiated is the maximum allowed while in the US they measure from the antenna port... In which case a 100mW US transmitter actually radiates more than that. To comply with the Australian regulation all AU transmitters are actually locked at 50mW USA standard. Of course they are sold as "100mW". I'm describing this poorly but recently learned this the hard way when I bought some used transmitters from New Zealand. Thought they were normal SMa but with the AU marking on the side it means they're 50mW. Everything else is the same and they work in US 400 mode just fine.

Patrick Tresch Posted January 12, 2016 Report Share Posted January 12, 2016 Hello, Ins't it that you can unlock the SMB/E01 (or SMDB) to enable the 100 and 250mW? I had to sign a agreement with the gov. provided by the (swiss) seller so that he unlock the higher mW values. With the remote I can see that it can switch between 50-100-250mW.

RPSharman Posted January 12, 2016 Report Share Posted January 12, 2016 Pat - Dealers are able to unlock the E01 version of SMs to enable 50/100/250, but it is not legal in many countries to do so. Quote Link to comment Share on other sites More sharing options...
Patrick Tresch Posted January 12, 2016 Report Share Posted January 12, 2016 Hello RPSharman, I understand the legal problem but many European contries give the right to use stronger levels than 50 mW depending the frequency used. https://docs.google.com/a/tjockishjartafilm.se/spreadsheet/ccc?key=0AgnGQulSs_YrdFAwZGZ2LWVjRkRuY0owOEtHcHZqclE#gid=0 From this thread: See you Pat Quote Link to comment Share on other sites More sharing options...

I don't think this is true anymore. It was true when Lectro first re-introduced themselves to Europe, but with newer tx they don't have that capability anymore Quote Link to comment Share on other sites More sharing options...
karlw Posted January 12, 2016 Report Share Posted January 12, 2016 The hardware is actually the same between an SMQV and an SMDB, only the firmware is different, so that the different units are compliant in different parts of the world, and thus are labelled as such.

So... it might be possible to turn a SMDB into a SMQV if I had a job overseas? Quote Link to comment Share on other sites More sharing options...
karlw Posted January 12, 2016 Report Share Posted January 12, 2016 Yes - that's correct. Servicing dealers should be able to do that, assuming the proper government paperwork is in order. Quote Link to comment Share on other sites More sharing options...

Patrick Tresch Posted January 16, 2016 Report Share Posted January 16, 2016 I've bought an SMDB and asked to unblock it to go up to 250mW, wich is allowed if you accept to use the legal frequencies in your country and sign a government paper taking responsability if you overpass your rights.
