Hudson Posted April 23, 2011 Report Share Posted April 23, 2011 Could i just quickly ask about a feature on the RH-1, I understand you can disable the volume limiter on the unit ? Is this true ? A review mentioned that this may only be possible on the USA units..... seems odd if this is true. Quote Link to comment Share on other sites More sharing options...
sfbp Posted April 24, 2011 Report Share Posted April 24, 2011 Yes you can change the RH1 not to have a volume cap. Problems: 1. The jog lever seems to wear out after 1 year and efforts to get into service mode can and will significantly accelerate this process. 2. You really should not be thinking about the RH1 as a playback unit. All HiMD units have Type-S which is the best playback for legacy MD bar none. Take the advice of most here, and save your RH1 for uploading. Quote Link to comment Share on other sites More sharing options...
Hungerdunger Posted April 24, 2011 Report Share Posted April 24, 2011 There have been discussions about this before, and I'm pretty sure the general conclusion was that there was very little difference after the tweak had been applied, especially compared to the possible damage that might be done by messing about with service mode. I don't know if I'm missing something here, or perhaps it's because I'm one of the oldies here and my hearing is already a little damaged, but I never find it necessary to listen on headphones at the maximum volume. With the RH1 the volume control goes up to 30; I'd say that it's very rare for me to listen above 20. If you are listening at full volume, then I hope you don't end up with tinnitus like me.

sfbp Posted April 24, 2011 Report Share Posted April 24, 2011 I think perhaps the point (made by Avrin IIRC) is that the limiting may be a rather primitive circuit that may actually detract from the sound quality if activated. I could easily be wrong on this, but I do recall him saying something about certain levels (23 on some units) being the "straight-through, no-amplification" setting. Whether that is affected by the volume cap (everything is decreased) or whether the volume refuses to increase past 25, I honestly don't know.

Hungerdunger Posted April 24, 2011 Report Share Posted April 24, 2011 For those with a lot of time on their hands, here is the main discussion (Although I'm sure there were others) Quote Link to comment Share on other sites More sharing options...
sfbp Posted April 24, 2011 Report Share Posted April 24, 2011 I just re-read. Avrin's point is that nothing actually happens unless you remove (or replace?) a bunch of resistors too. This will be almost impossible on the tiny motherboard, so probably you are better trying to get a non-limited model from the start. Quote Link to comment Share on other sites More sharing options...
Soundbox Posted April 25, 2011 Report Share Posted April 25, 2011 I have the European RH1 and after around 2 weeks of use I entered service mode and 'removed the cap'. The reason I did this is I have some very quiet recordings and the cap seems to limit the volume control rather than the output level. After doing the mod I noted the sound was a little stronger and even without the resistors bridged I got a better output level. I will say that I did note a difference before and after. I use my RH1 for listening - but only in a chair or plugged into my Hi-Fi - not for outdoor/rough use (too valuable). Quote Link to comment Share on other sites More sharing options...
