Avrin Posted October 22, 2006 Report Share Posted October 22, 2006 (edited) Knowing about the MP3 flaw in second generation units, and having a need to listen (temporarily) to some DJ sets downloaded freely from http://www.o-c-d.co.uk in MP3 (128 kbps, and no way to improve) on my RH10, I decided to really test some ways to compensate for the flaw. Starting from the "classic" 0,0,0,0,+1,+2 (notches), and working further (analyzing the results in Adobe Audition), I found out that the sixth (the rightmost) EQ control on the RH10 is not 10 kHz (as stated in the manual), but is actually 15 kHz. This can be easily seen by lowering the other controls all the way down, maxing the sixth one all the way up, and taking a spectrum analysis. It gives a healthy peak at exactly 15 kHz in the spectrum.The other five controls are more or less at their officially stated values.Having spent a few hours experimenting, it still turns out that the "classic" 0,0,0,0,+1,+2 is the best way to compensate for the flaw. The spectrum does not become perfectly linear, but it is as close to linear as we can get.Now I wonder about EQs in other units. Well, the RH910 is certainly the same, but how about the RH1 (not that the EQ will be ever needed in RH1)?

greenmachine Posted October 22, 2006 Report Share Posted October 22, 2006 A useful flaw in my opinion - i wish lowest band had the same flaw, something like 30-60 instead of 100Hz.I did a few measurements with my NH700 a while ago and came to same conclusion:http://forums.minidisc.org/index.php?showtopic=13741 Quote Link to comment Share on other sites More sharing options...
Avrin Posted October 23, 2006 Author Report Share Posted October 23, 2006 Thanks for the info! Raising (or lowering) the rightmost control on the RH10 also affects the overall sound level (as measured by Adobe Audition), and quite seriously!

doomlordis Posted October 23, 2006 Report Share Posted October 23, 2006 Thanks for the info! Raising (or lowering) the rightmost control on the RH10 also affects the overall sound level (as measured by Adobe Audition), and quite seriously!In what sense? do you mean volume? , i have gotten used to MP3 (eq +1 +2) on the RH10 but if you listen to the RH1 you will hear the difference, it is clearer and more refined sounding, the bass on the RH10 is quite in yer face where as the RH1 is more defined , rounded and more accurate.The RH1 also has TOTAL silence between tracks, the RH10 is also very good in this area but my Nano has a noticable humm/hiss when switched on.I am going to buy a RH1 at Christmas, i had my mates for a week and it won me over , i will be buying a MC40EL though as Nav is tricky with supplied remote.

Avrin Posted October 23, 2006 Author Report Share Posted October 23, 2006 (edited) I mean the sound level indication in Adobe Audition. The hearable volume does not change much, since the sound energy is not seriously affected (it is concentrated in the low and middle ranges). But since the rightmost control affects a wide frequency range (starting from 10 kHz, and going all the way up to about 20 kHz), the measured level does change, and quite seriously.Still waiting for the RH1. It is not easy to get it here in Russia, but the local Sony office promised to officially bring it here in November.

Sparda Posted October 25, 2006 Report Share Posted October 25, 2006 So the equalizer in all units have this issue (if you call it)? And the statement about the RH1 not needing equalizing is not true, in my opinion the equalizer changes the sound to your liking, adding more treble or bass, meaning its not like its saying the amp is bad because it needs equalizing. I hope that made sense, it was like a run-on sentence . But yes the RH1 sounds really nice even without equalizing. I really can't understand how some people can bear the crap "Digital MP3 Player(s)" puts out, rather listen to leaves rustling, which is quite soothing.

Avrin Posted October 25, 2006 Author Report Share Posted October 25, 2006 (edited) Sparda, I only meant that the RH1 does not need any equalizing when playing MP3s. For me, the flat (ATRAC3plus) sound of a good HiMD unit (RH10 as of yet) played via my good old $**,*** stereo system is quite enough. Proper cabling is a different story.And when I'm for a walk or a journey, the same RH10 is always ready to go. The little thingie has already survived some situations, after which I personally (my body) had to be repaired.
