Hi guys. Here's an update. After several months of trying to get to the bottom of this I feel I've made some progress. I've tested DPA mics (all models, hardwired, and with microdot adaptors) on 5 separate block 606 srb systems. All with the same poor results. With the 411 and venue receivers, the DPAs sound as they should. Also, on a US bought block 24 sra, sounded as they should. I'd really love to hear from anyone running block 606 srb receivers with DPA lavs who's getting good results. Cheers guys.

Thanks Larry, I've arranged to pay Pyers a visit next week. I'll let you know how I get on. Best, Seb

Hi guys, I took my bag in to Henry last week, sadly we couldn't get to the bottom of the problem. We tested the resistor values that Henry had fitted last time at 1k7. We double checked his work against the recommended wiring and are both happy that this is absolutely not a wiring issue, I have the same results with the recommended DPA adaptors (3056) as I do hardwired. Henry has wired up 100s of DPAs with no complaints, so the wiring was never in question for me. My DPA4071s have been back to DPA and been given a clean bill of health, reterminated with microdots, and still sound bad through my lectros. The problem is that I just can't get enough level into my tx. According to the manuals, I should be setting levels on the tx so the first red l.e.d. occasionally reads the peaks. With my tx on full (44) I have to shout to get the first l.e.d. to turn red. I have 4 transmitters and have tested through all of them, so it's unlikely a fault with the tx. I asked a few of the guys on facebook groups this week what sort of gain settings they regularly used on their transmitters and the average answer was 20-25. With all my mics (tr50/kat66/cos11) I seem to be having to run them much hotter (35-40) to get decent signal to noise ratio. Any more thoughts anyone?

Hi Rich, I'm London based, I'll be taking my whole bag in this time! Cheers.

Thanks for all your responses guys. Just to clarify, I've tested mics both hardwired and with the appropriate adaptor (dad3056) with the same poor results. I have never used the 2021 adaptors. I'd also like to mention that I've never been anything other than happy with the work Henry at rfs has done for me. The fact that I'm having the same issues with brand new mics that are yet to be rewired suggests to me a problem other than wiring. The mics will be going back to Henry this week to try a lower value resistor, although I'm not entirely sure this will solve the problem. I'll post the results as soon as I've tested them. Thanks again.

They were wired by the guy who wired up all the Les Miserable lavs. He knows what he's doing.

Do you care to elaborate Vasileios?

Hi guys, I've read through all the threads about wiring dpa lavs for lectro transmitters but am still having some issues. I'm running Lectro SMB (single battery) transmitters (block 606) into SRB recievers. Rx set to line level out, my other lav mics (cos11, tr50, kat66) all sound great. I sadly can't get my dpa lavs to sound anything other than awful. Ive tried both 4071 and 4073 with dpa microdot adaptors DAD3056, and hardwired rean plugs, experimenting with different resistor values. My tx gain value for cos11 and tr50 is generally around 30 lighting up the -20 red led, however, even with the tx gain maxed at 44 and talking very loudly I still can't get my dpa to turn the tx led red. As a result of not being able to get enough level into the tx the resulting sound is noisy (hiss) and washed out. It sounds quite similar to using a denoise plugin quite aggressively. The dpa mics have been tested and a/b'd with an xlr adapter so I'm certain mic fault isn't an issue. The mics have been wired up for me by a pro so I'm also happy that the wiring isn't an issue. I know Rob Sharman is using 4071 with the single battery transmitter with his gain around 20 and getting great results which gives me hope that this setup should work. Any ideas greatly appreciated.
