Anyone dare to try any physical hacks on their MZ-r700?

eg adding the necassary power mod for personal disc memory to work

adding a syncro rec switch

adding the sound button off the remote (or any other u fancy)

buying the flat sony rechargable battery, hacking the plastic back off with it's ugly bulge and screwing on a tidy aluminium cover

even buying a wrecked 900 off ebay and transferring the guts of your 700 into its sleek case. there were a few going cheap last week but i missed em

it's all out there! i've been thinking alot about it, just need someone with the knowledge of the electrics.

Think about it, you could get better than anyones, not what you get but what you WANT.

Anyone already done something simalar?

how closely related are the 900 and 700?

opinions please!

it may be that you just need the lcd to see what's going on and you can adjust the setting by following the instrucions exactly.

could be.

What i really really want i discover today is to modify it to produce a full line level output when required, it's far too quiet when plugged into my stereo.

Not entirely sure what's required to achieve this end, how does the 900 manage it?

Yeah, I know. I tried to put a resistor to simulate a sound buttom in remote connector and it didn't work. I'm sure, a LCD remote is need it, I don't know why, but it's need it.

i did the hack and i don't like the way the sound settings 'sound.' i think they sound way shittier. i'm using the headphones that came with the r700 and a pair of the new sport style ones...but if the players sounded better with out the hack, you think i should change it back?  

or am i missing something? do you absolutely need the lcd remote to access the other functions?

Your are problably right I don't dare trying it.I just know that the sound mode in the n707,wich I gave it away immediatly,is worse than the old megabass mode,the basses sound awful!So I don't know what would happen if I try.The new feature probably reduces the EQ bandhwidths and so you cannot control the range of say 180Hz anymore,but only a wide setting,say from 50 to 300 in the whole.Shelves instead of peaks,you know.

For the MZ-R501, setting 867 to S67 and 868 to S01 enables Type-R encoding. Since R501 uses the same DSP IC with R500, R700 and G750 (CXD2671-204GA), you may be able turn on Type-R for these units as well. I have an MZ-R910 and compared the recordings, I believe that Type-R was really activated for my MZ-R500. I can't be 100% sure of this, but at least the recordings sound cleaner than before.

Have fun!

P.S. I don't know if it works for R900 as well, it has a different DSP IC (CXD2671-202GA).

"Digital MegaBASS" is just a preset of "Digital Sound Preset"

Sound1: T: ±0 / B: +1

Sound2: T: ±0 / B: +3

Hey sam where did you go to activate the type-r setting? i have the 700 so i'll try it and post my results.

Can anyone tell me anything good that can be done with the audio settings in the service mode, i don't do any messing round in service mode much. maybe i should.

ps, i recon the new bass settings are better, they're cleaner and more subtle

Do whatever you do to get into the service mode. Press Vol+, Vol-, Vol-, you are now in 800. Press Play then Vol+ 5 times, then press Play for 7 times, this get you to setting 867. Use Vol+/Vol- to change the value to S67, then press Pause to save. Next press Play once (to get to setting 868), change the value to S01 and save. Then press Stop several times to go back to main menu.

To hear the difference between Type-R and normal ATRAC, you would need a very good playback system. I prefer using a unit with proper line out and connect to a good stereo for comparasion.

it still plays just as well as before - relief cause i'd have to borrow my mates md to get the orig values again,

tomorrow i'll make a new recording of the pixies in stereo and compare it to my other md of this album

Thanks sam for this interesting hack, have you got any others?

the testing tone for type r would be useful. Although my comparason revealed little difference, it was cleaner and (maybe), but this could be caused by other factors, i don't have good enough minidisc player for the difference to be apparent. Still, it's p[retty good, maybe the testing tone will reveal all

Just wanted to add another thumbs up to the diligent work on this hack! Sorry about your MD unit.

I've got a 500 myself and the ability to use shuffle without repeat is worth the hack alone! A little note after messing with this feature: It appears that with the 500, the unit loses track of what songs it has already played if you press Stop at any time during your program. Someone else please confirm this, I have tested this feature by skipping through all tracks randomly on my unit, and it finally does end with no repeats. If I press stop, it 'forgets' the tracks it has already played and will cycle through all of them again.

I hear all this talk about adding some mz-r900 functions to an r700.  Will someone post directions, step by step for doing it to an r700? thanks
