Re: [Elecraft] RES: Yamaha CM500
I use CM500 for few months now. I don't hear difference between Heil proset and CM500. Microphone is a bit different and TX EQ needed to be adjusted and mic gain reduced significantly. But the main CM500 advantage, aside from being 3 times cheaper than the Heil, they are much more comfortable, I can wear them for more than 10 hours straight during contest, while Heil would kill my ears after 3-4 hours. 73, Igor, N1YX - Original Message - From: Robert Harmon k...@pacbell.net To: Gary Gregory garyvk...@gmail.com Cc: elecraft@mailman.qth.net Sent: Tuesday, January 11, 2011 2:28:55 AM Subject: Re: [Elecraft] RES: Yamaha CM500 O.K. you guys, now you've done it.

I checked it out with the MP that's still on my shelf (and for sale), and got critical on the air reports from a nearby super contester. The CM500 works just fine with the Yaesu, and sounds great. No adjustments needed for headphones. For the mic, you will need to set the mic gain VERY LOW to avoid overdriving the Yaesu's mic input. This does NOT imply anything bad about either the mic or the rig -- it's just that the mic is hot and the MP has plenty of available gain to accommodate mics that have very low output. And, as with any mic and the MP (or it's descendents), you need to carefully select the TX DSP that does the least damage to the audio. But if you DON'T turn the mic gain way down, or if you don't select the right DSP, the audio will sound just awful (like far too many SSB contesters). :) 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] RES: Yamaha CM500
Hi Folks I just got a pair of CM500 which came without any catalog and I would kindly ask the following questions: 1) I tested on my K3 and the boom set is working fine 2) I noticed that the CM500 has more base and less high frequency respond comparing with the heil. 3) Has someone tested for yaesu rigs? What are the results?

Re: [Elecraft] RES: Yamaha CM500
Hi, I also bought a pair of these based on the recommendations on the reflector and also on the Yahoo group. I have not put it on the air yet as I was thoroughly disappointed with the headphones on receive. There seems to be a profound lack of highs compared to any other headphones I own including a pair of Heil and a pair of Koss. I also strongly dislike the fact that each earpiece has a wire coming out of it. I'll keep using my Heil proset until they break.

Re: [Elecraft] RES: Yamaha CM500
Lack of highs? Not mine,besides,does any ham transmit today with more than 4000Hz at the high end? answer is NO,most of them are below 3000Hz,at that freq ANY headset will response well.Also I injected an audio generator to my CM-500 from 20 to 5000Hz and I heard the tone from 60(my ears) all the way up to 5000Hz with same level,I don't see why they has lack of highs.Besides the K3 has an excellent RX EQ and you can tailor the received audio to your personal taste so If you think it has too much lows,then cut them up with it. I have been using those Yamaha for more than a year and for me they sound as well as ANY other headset. Maybe some users feel bad because they are cheap compared with Heil, Senhisser,and others.

Re: [Elecraft] RES: Yamaha CM500
Hello again, I am not talking about anything above 2700Hz at all. With my receive bandpass set to 300-2700Hz the CM-500 sound definitely muffled compared to any other headphones I have. Yes, I could compensate with the EQ, but then it would be unuseable with any other headphones I have since there is no macro support to quickly change the RX EQ settings quickly. Until that happens the CM-500 stays shelved in my shack. AB2TC - Knut AD4C2009 wrote: Lack of highs?

Re: [Elecraft] RES: Yamaha CM500
Hector, I too love my CM-500 but then I set the RX EQ to suit and I don't have a 'collection' of headsets...certainly would not waste money on Heil gear...too rich for my blood and they are not real robust. Also found with the Heil stuff you have to do some serious adjustment on the TX EQ which would make microphone changes cumbersome. I have settings now that enable me to use an old Turner +3 on the front panel and CM-500 on the rear. I am told there is little to no difference in audio from those who know my rather terrible voice. I was not blessed with broadcast quality vocal chords...:-) Now my XYL (this is strange) has a great voice for HF and everyone who chats with her comments on the audio and tell her she sounds better than the OM...:-(...now that does suck!!! The settings you sent me way back when Hector work great for me, well done with your testing back in the early days..My CM-500 is a definite keeper.
