himdman Posted February 9, 2005 Report Share Posted February 9, 2005 HI,Today I had a chance to peek at some himd service manuals.It seems the destination is controlled by code 113 in the service menu of the players.I haven't had a chance to test them yet cause my unit is being repaired. Maybe we can bypass the euro volume cap this way.EDIT by kurisu: Click here for info on how to enter service mode.Enter these values at code 113 and press pause to save.MZ-NH900 US 21Canadian/Australian 41Europe/UK A1Hong kong/Taiwan 25 MZ-NH1US/Australian 01Europe/UK 81Hong Kong/Taiwan 05 MZ-NH600Europe/UK A0E (??) 25 MZ-NH700US - (Not a US model??)Canadian/Australian 20Europe/UK A0Hong Kong/Korean 25E91/Mexican 20MZ-NHF800US 50Canadian/Australian 30Europe/UK B0Hong Kong/Korean 34E91/Mexican -Hope these are helpfull.......

xispe Posted February 9, 2005 Report Share Posted February 9, 2005 i've tried it on my nh700. I have a euro capped version.I set it to Hong Kong / Korean (25)I notice some difference in the sound, i raised the volume up to the max and before there was almost no change in sound from 25 to 30, but now the volume raises constantly up to 30 and at 30 things are really loud! (So loud that my headphones started to make weird vibration noises... ) So the good news is that i've kind of damaged my headphones with this! Now my nh700 is as loud as my r70 Tomorrow i'm going to check if on my car the volume is higher using the homemade line-in of my sony head-unit Thank you!For all the others: test it!The code 113 is under the MANUAL section.

Philgood Posted February 9, 2005 Report Share Posted February 9, 2005 (edited) I'm willing to give it a try.i own a mz-nh900 unit in his european version and i'm quite unsatisfied with the output volume when i'm walking down the streets of south-spain. you know it's kinda noisy here all people who are visiting me are shocked when we went to bars to take some welcome drink and the local people aren't hesitating to shout eachother though in a friendly kind of way but i'm just lack of a little more output from my unit.BUT...i'm still waiting that one experienced user from this forum is giving it a try before me or at least can taking me some doubts i still have about entering in the service mode.i will read again that thread about it. i'm just to curious...only afraid of that himdman have really honest intentions. sorry for saying that himdman ...so, anyone ?p.s. isn't it still impossible to save changed values in service mode ?...will have to read that thread again, i think.heh, great. seems that someone there just heard my pray. hi xispe Edited February 9, 2005 by Philgood Link to comment Share on other sites More sharing options...
xispe Posted February 9, 2005 Report Share Posted February 9, 2005 It's possible to save the value using the pause button. I've saved this one with no problems. When i press save the disc icon lites up, and the current value is saved. Link to comment Share on other sites More sharing options...

Philgood Posted February 9, 2005 Report Share Posted February 9, 2005 (edited) ...so i just entered in service mode. got down to manual and into the 111 and it started to count up...what next ?i'm still trying out to find the right navigation key combis.sorry, could someone here assist me a little ?well, just got to that site of aoix and i'm reading through it...hold Edited February 9, 2005 by Philgood Link to comment Share on other sites More sharing options...
Philgood Posted February 9, 2005 Report Share Posted February 9, 2005 (edited) just get stuck as soon as i entered some value because its changing constantly. how can i change that value for 113 ?------------------------------------------------------------------well, finally i got managed to do the hack but i couldn't hear any big difference in volume between the default value A1 and 21 or 25.but here is the interesting.what i was noticing as i got to the equalizer section stepping through the presets while listening to music was that there is a difference in volume when i'm listening the same piece of music with the UNIQUE eq-preset switched on in a hacked mode.either with the value 21 or 25. it just seems louder than listening with the UNIQUE eq-preset in the default mode(A1).my idea is that the 113 code is controlling a kind of auto-gain for the eq-section just to prevent distorsion with extreme settings. just try to raise the basses at high volume output of a record which already has strong basses. it probably will get distorted, what i think happened to xispe . winamp has got that option too.anyway.i'm thrilled about hacking my unit. thank you.

xispe Posted February 10, 2005 Report Share Posted February 10, 2005 first if you are stuck, just press stop several times till you get the service mode flashing screen.Here goes the sequence after the flashing service mode screen:(Key | Display)VOL+ | 0 ManualFWD | 100 MTFWD | 110 NVFWD | 111 xxxSCC (xxx values counting up...)FWD | 112 NoClockFWD | 113 xxxS25 (xxx values counting up...)now to change the value after S just use VOL+ to increase and VOL- to decrease (in my case it was set as A0, so i just pressed VOL- till i read 25)PAUSE to savethen press stop till you get to the first menu, with the flashing screen..To quit the service mode remove all the power sources from the unit. Remove battery and / or AC adaptor plug.After that the unit should start normally Link to comment Share on other sites More sharing options...
Philgood Posted February 10, 2005 Report Share Posted February 10, 2005 thanks xispe,it worked, yes. sorry about just re-editing my previous threads. think it can be kinda confusing to follow the discussion that way.can you verify my opinion ?

himdman Posted February 10, 2005 Author Report Share Posted February 10, 2005 I'm glad it has worked out for you guys.I'll get my unit back by friday so I wil then give it a try.In the mean time I will try to get hold of a complete service manual.As for the 113 codes, the manual clearly stated these were destibation codes. I don't know if it only affects sound. Link to comment Share on other sites More sharing options...
LostTime Posted February 10, 2005 Report Share Posted February 10, 2005 I'm sorry to say that, but this "hack" does not work!I have a nh900 and changed the value to 25 (Japan) but I can't hear any differences. Link to comment Share on other sites More sharing options...

dex Otaku Posted February 10, 2005 Report Share Posted February 10, 2005 Perhaps someone could plug their HiMD into their sound card, record a test file with known levels without ever adjusting the computer's input level, and repeat this for each setting?This would prove whether anything changes or not.

xispe Posted February 11, 2005 Report Share Posted February 11, 2005 ok! here's the proof I've recorded about 14 seconds of the same hi-sp track, various times, at both hacked mode (25) and standard (A0) mode of my nh700. All of these were recorded using the same input volumes, and the output settings of the unit were changed for each recording.LAME version 3.96.1 was used with preset --extremeStandard mode (A0)Vol 30 - No EqualizerVol 20 - UNIQUE EqualizerVol 25 - UNIQUE EqualizerVol 30 - UNIQUE EqualizerHacked mode (25)Vol 30 - No EqualizerVol 20 - UNIQUE EqualizerVol 25 - UNIQUE EqualizerVol 30 - UNIQUE EqualizerNotice the difference when the equalizer mode is on... from 25 and up... with the headphones and EQ on, i've been noticing that the signal is actually more stronger in hacked mode, rather than in standard. In the hacked mode with no equalizer and at maximum volume (30), i've been experiencing higher output in my car. I use a sony head-unit with a "homemade" line-in input - [basically it simulates that a cd changer is present and opens up the BUS AUDIO IN rca inputs]. Ok this is all! Enjoy!

LostTime Posted February 11, 2005 Report Share Posted February 11, 2005 Shame on me! I am very sorry xispe is right.From volume-level 25 and up the hack worksThank you to himdman!!!(I have a nh900 and changed the A1 value to 25 (MANUAL --> 113 --> changed value) Link to comment Share on other sites More sharing options...
Christopher Posted February 11, 2005 Report Share Posted February 11, 2005 Wow, this is huge! So can we safely say that the limitation on volume has been lifted? Does anyone object to me announcing this in the next "forum focus"? Link to comment Share on other sites More sharing options...
dex Otaku Posted February 11, 2005 Report Share Posted February 11, 2005 [pulling out spectrum analysis software]Expect some graphs of sweeps to show the differences [at least between an NH700 set as Canadian as hacked as "25"]. Soon. Not right away, but soon. Link to comment Share on other sites More sharing options...
Christopher Posted February 11, 2005 Report Share Posted February 11, 2005 I wasn't aware that the Canadian version of the NH700 was capped in any way. Link to comment Share on other sites More sharing options...
dex Otaku Posted February 11, 2005 Report Share Posted February 11, 2005 MZ-NH700US - (Not a US model??)Canadian/Australian 20Europe/UK A0Hong Kong/Korean 25E91/Mexican 20This would suggest that there is some difference between Hong Kong/Korean and Canadian/Australian. The interesting thing is that since CA/AU is a lower value, it might actually be slightly less restricted than HK/Korea - assuming there's some kind of linear relationship here. Perhaps setting this to '00' would completely uncap the amp. Not that I'm proposing anyone actually try this, I'm just saying - the higher the value, the lower the cap threshold [or ratio] is what appears to be going on.In any case, my silly Koss pseudo-canalphones are so sensitive that they are deafening with my unit at 13/30 with most music. My Sennheiser HD330s start to hurt my ears at about 19/30.edit:Whatever the case may be, it's somewhat important to note that this setting is bound to have at least a minor affect on battery life as well.

jonny mac Posted February 11, 2005 Report Share Posted February 11, 2005 I have a UK MZ-NH1 and, while it's not technically Euro-crippled, the volume is not exceedingly high but good enough to get by. I've noticed that above volume 24 increasing the volume makes no difference at all and this is the first time I've read mention of this by someone else. How likely is it that the NH1 can have the volume increased or is this a hardware issue? I'm not sure I know enough about hacking to be confident enough to risk it myself Link to comment Share on other sites More sharing options...
Christopher Posted February 12, 2005 Report Share Posted February 12, 2005 The NH1 is not known to have any limitation on it's volume in any region. Link to comment Share on other sites More sharing options...
jonny mac Posted February 14, 2005 Report Share Posted February 14, 2005 ALL current minidisc players are volume-limited when compared to models released 3 or more years ago. I think that if the volume settings above 25 are ineffective on the 700 and this can be disabled then the same is possibly true on the NH1 Link to comment Share on other sites More sharing options...
