Version 211:  Corrected an annoying problem that only a few owners experienced. When muting was initiated via the remote, the preamp would ramp down to zero volume but would then immediately ramp back up again. Only a few users experienced this mute yo-yo behavior because it only happened after switching inputs using the slow mode. Using fast input switching would not trigger this behavior. A simple enough fix but took us good while to figure out why this was happening since most units did not exhibit this behavior.

Version 215:  This update also includes intermediate updates 212 through 214. Most of the changes since rev 211 were "under the hood" changes and minor fixes. However, this latest update includes the following key fix plus a new feature related to Phase Inversion:

Fix - Several customers ran into an intermittent problem with waking up the preamp after the display timed-out (turned off). This has now been fixed.

New - We've modified the menu structure slightly to include a new option labeled "VolDisplay". VolDisplay now allows the user to select between 3 options as to how the secondary (left/right) controls work when viewing the default volume control display.

The default is "Balance" which is the original approach where left/right button on the remote adjusts the channel balance.

The second option is "Input". When this option is selected the left/right controls in the volume control display will now switch the inputs instead of adjust balance and a whole new main menu item labeled "Balance" becomes available which is where you'll need to go to change channel balance.

The third and final option is "Phase/Input". When this option is selected the right button will change the input to the next input. The left button will toggle the Phase Inversion (more on that below). Most of you will not have Phase Inversion enabled so you can ignore this option.

Phase Inversion - Owners/buyers of V25 based balanced passive preamps now have the option to add the phase inversion feature to their balanced preamps. This does NOT apply to single-ended units. With phase inversion, external inputs #1 and #2 are also wired to inputs #5 and #6 internally except the balanced phases are wired oppositely on #5 and #6. By toggling Phase Inversion on the remote, the selected signal swaps the + and - phase signals. For those keen on optimizing phase alignment during playback, this can be a handy little feature.

Hi Morten - thanks for ALL the help offline in getting my controller integrated into my project!

Is there any way for the software to detect if there's a signal playing? A feature I'd love to see is an option to auto-shut off after X minutes/hours of no signal to preserve the life of the LDR modules.

Thanks!

The current design is not able to do this. It would require some type of active or passive signal detection that would reset a timeout timer anytime the signal exceeded a certain RMS level. This can get quite involved not because it's all that hard to do in conceptually but because the design can get quite involved in order to prevent false positives (shutting down when you're listening to your system) and to avoid not shutting down ever because the detection threshold is too low.

What COULD be easily implemented is an auto-shutoff when the user hasn't provided a control input after say 6 hours. This shutoff time period could also be made user adjustable anywhere from 0 (feature off) to say 24 hours.

I welcome everyone's thoughts on this.

Cheers,
Morten

That makes total sense. And you are right in that based on the thresholds, it could potentially create a frustrating user experience.

I tend to change volume quite often. The longest I can imagine not changing volume is

a) if a single album is playing (normalized volume)
b) if a movie is being watched that doesn't have much variability (explosions --> soft speech)
c) if a radio channel is playing and I'm entertaining

An adjustable auto-off since last key press would be *awesome*. I'd probably set it to 3h. Perhaps a countdown of 15 seconds that says "Powering off in..." so user could choose to press a button and override?
