Have other E835 users had this same problem? If so, what mic preamp did you use? Not interested in an elaborate mixer/equalizer/preamp, just need some more gain.
Which input are you using? The 8 pin on the front or the BAL input on the rear? Did you select the correct input on the P/CW panel? I use the balanced input on the rear and if I am set to a different input, it seems that I do not have enough gain until I select the proper input. My input selection only changes when I use the radio remotely.
The next step you may want to try is the front 8 pin Foster connector. If someone can loan you an XLR to 8 pin cable that is wired for a Yaesu mic (ex: Heil CC-1-XLR-Y-BAL) that should work. That will tell you if the issue is the mic itself or the rear BAL input on the radio. The aforementioned cable is $36.95 at HRO unless you find another at a musical instrument store. Good Luck.
Well, if you plan on sticking with that very low output mic, I’d strongly recommend using either the Symetrix 528e, or its replacement, the Symetrix Voice Processor 2x. Both are MD’ed, so you can find them on eBay. You can easily snag either piece of kit from eBay for a song-and-a-dance. This will solve all of your problems with low mic audio.
Another good choice would be to get yourself an Electro Voice EV RE27N/D mic. This particular high-quality microphone is famous for its characteristic very high output level (it’s a good 6dB higher than most pro mics, such as the old EV RE20), so it likely will not need a preamp before hitting your 6700, although I have never run it barefoot myself.
A third alternative that may work is the Heil PR-781. While it also is hobbled with a low output level, it may have at least a somewhat higher output level than your Sennheiser E835, so it might do the trick. On the plus side, it is a very inexpensive entry level mic, with a street price of about $150, brand spanking new. I’d guess it could be had off-of eBay for a lot less, too. Keep in mind, though, I have seen huge claims and counter claims re: the PR-781 on this board, and whether it “works” with the 6700, or not, sans a preamp. The opinions are very split on this, with some 6700 users claiming it works OK without a preamp, and then you see tons of posts here saying they have their PR-781 mic gain cranked all the way up to max on their Flex 6700, and the thing is just not cuttin’ it.
Maybe someone else who has used the EV RE27N/D can weigh-in on the pros/cons of going directly into the 6700 with the RE27N/D, versus using a good preamp/processor ahead of the 6700, along with this mic.
Hope this helps.
you want to keep it simple but still have Hi-FI audio here are a few
mic that have worked great for me connected straight into the
Heil PR40 Or 781
Electro Voice RE27N/D
Even a $99 Shure SM58 sounded great.
If you add outboard voice processing you can enhance your transmitted audio even further just be aware of potential RFI issues.
you are just looking for good narrow DX type audio the stock hand mic or
headset with proper EQ works perfect.
