Need help using microphone and my Denon MC6000

Here's my report

OK - had a middle school dance last night - loud music and plenty of high volume action on the mic.

Given that my ATW is in my rack, I forgot about the volume knob in the back. I set the Mic1 volume on my controller to about 30%, changed the attenuation to -6db on the transmitter and turned the volume knob on the back of the ATW down so that the output speaking volume was appropriate (without music playing). This resulted in lot of headroom for the frequent, "everybody jump, jump, jump!!!" and when the music was cranked up, the microphone output was very clear.

The other microphone(s) I use are my Gemini UHF5200 - these are generally my backup mics used sometimes for client speeches, karaoke, etc. There is a volume knob on the front of the receiver for the individual transmitters, but this didn't appear to change the clarity of the speech output. From what I can tell, there is no menu option to adjust the attenuation - although I'm aware of some hardware adapters that can accomplish the same thing. Oddly enough, I didn't experience the same garbled speech as I did before.

So I'm very happy with the adjustments made to my primary mic. Reducing the input into the controller has allowed me to actually use the volume knob on the MC6000 above 1 (since the unit is so HOT).

To address another concern I've had, I heard a considerable amount of ambient noise (hiss) when each Mic button was actuated on the controller when the transmitters were on. Imagine a best man giving a speech - lots of hissing from the speakers - especially when you have a quiet speaker - or one that holds the mic down at their belly DESPITE you reminding them to hold the microphone close to their mouth :) The MC6000 uses an XLR in for Mic1 and a 1/4" for Mic2. The noise on my Mic2 was so bad that I would never use it unless the music was loud enough that the guests might not notice. I recently purchased a couple of quality balanced 1/4" cables to connect my 6000 to an amp for a 2nd pair of speakers. I checked my 1/4" for the Gemini Mic and sure enough, it was unbalanced. Since I wasn't using a 2nd set of speakers I replaced the cable with a balanced one and WOW what a difference. Barely any ambient noise. I was unable, however, to find an XLR in my collection of many that sounded any better than the one I already had in place. So I used my Gemini the entire night, and it was great.

Now I'm on the hunt for a short (3 foot?) high quality XLR cable.

Hope some of this helps Rhino and Chubby - or others battling with the HOT MC6000 microphones.

Noise rejection with balanced connections is all about the electronics at either end so as long as the cable in between has 3 good conductors it won't make any difference what "quality" it is. What you're experiencing may just be a difference in these two wireless mic receivers or in the way the mic channels are processed inside the MC 6000. As an experiment connect the Gemini to Mic1 with an XLR to compare idle noise levels, and do the same with ATW connecting it to Mic 2 to compare performance. If the ATW is noisier no matter where it's connected then that may be as good as it gets.

I am not going to read everything but I did read the first page. I do not own the Denon 6000 but I do use a 3000 series cordless system so I thought I would comment. I always have my 3000 set to -6 dB to prevent distortion from the source, the factory 0 dB setting was way too hot. Also make sure the knob on the back is set in the middle.

the factory 0 dB setting was way too hot
Bill also said the factory setting was 0 db. But when I follow the instructions in the manual to reset everything to factory default, +6db comes up. From the manual "Available choices are +12 dB, +6 dB, 0 dB and –6 dB. The default setting is +6 dB. " I wonder if they came out with subsequent manuals with a different (and more wise) recommendation.

My voice is quite bold, and I have the setting on the back barely up from "off" - maybe 10% on? But then again, my testing was done at a school dance, not a wedding (my primary gig).

Sorry, yes I believe you are right that the factory setting was +6dB. I found all settings too hot except for the -6dB.

I stand corrected. This may be a new factory setting since I've been an AT dealer around 35 years. I'm sure it was 0dB in the past. +6 is way hot IMHO.
 
Ghosts in the machine!

I just got the MC6000 the very week I saw this thread so imagine my anxiety when I finally hooked it up! Then my fears became real as I too experienced that horrible noise coming from the mic 2 input. I was running a XLR to 1/4in cable from my Audio Technica 2000 receiver into mic 2 and XLR to XLR from a second AT 2000 into mic 1. The noise from mic 2 was simply unbearable despite trying several cables while mic 1 was deadly silent when engaged. Only when I tried a wired mic into mic 2 was it quiet. So here I was thinking that despite being an otherwise awesome piece of gear I might have to return it since I often need at least 2 wireless mics on most gigs :(

So then I decided to take a chance and take it on a gig Saturday, fitness show with just background music and 2 mics. I usually use a small Yamaha board or my bigger Soundcraft board on PA jobs but I really wanted to see how the MC6000 would perform live. I had a Rane MP2 in the rack as back up, though it only has one 1/4 in mic input, which is very quiet by the way. Following the advice of others here I turned the receivers down to about 3-4, ran XLX into mic 1 and XLR to 1/4in into mic 2, set mic gains at 12 o'clock,master volume at 12 o'clock, flat eqs, amps open wide, turned mics on and heard...silence!

Not a buz on either mic input and I was using the same cables and gain structure as at home, no processing between mixer and amp. The mixer was flawless all night and I loved mixing live during the show using Traktor Pro 2.

I set everything back up at home tonight and still no noise on mic 2 so hopefully the gremlins are gone for good! I totally love the flexibility of this controller and can see it being used often for small PA jobs as well as DJ gigs. The sound out of this thing is amazing!
