Here are the last 3 V2 software updates. Update 1.1.0 is significant. Latest cummulative build (1.1.2) available here: http://www.tortugaaudio.com/downloads/
1.1.2 - 7.15.14 - This update is primarily relevant to those who only use an Encoder and not the Apple Remote to control the V2
New: Can now toggle AutoCal on/off with Encoder via quarter/half turn to right
New: Status LED now flashes briefly every 2-3 seconds when AutoCal is active
New: Left display module in dual display system now shows which LDR is in AutoCal (1-4)
1.1.1 - 7.7.14
Fix: Removed blinking of numerical display when changing volume. Status LED still blinks as before. Bug was introduced in 1.1.0.
1.1.0 - 7.6.14
Change: With the release of Rev 1.1.0, we have made the following changes to how auto calibration is run:
* AutoCal now runs only when manually initiated by the user while the V2 is turned off but still connected to power. We do recommend that the V2 be powered but turned off when not in use.
* AutoCal is started by pressing the Enter/Center button on the remote which disconnects the V2 from the audio input and output.
* Once AutoCal is initiated, it runs through one full cycle of LDR calibration in the following LDR sequence: right-series, right-shunt, left-series, left-shunt.
* Upon completing a full cycle, AutoCal shuts off and the V2 is reconnected to the audio input and output.
* While AutoCal is running it can be shut off prior to completing a full calibration cycle by pressing the Enter/Center button again on the remote. The V2 may not react immediately to this AutoCal shut down command and it may have to be repeated. We recommend you not interrupt the V2 during a calibration cycle once initiated. A full calibration cycle typically takes around 10 minutes.
* While AutoCal is running, you can cause AutoCal to interrupt calibration on the current LDR and switch to the next LDR in the cycle by pressing the Right button on the remote. If you switch through all 4 LDRs then AutoCal will shut down thinking its completed a full calibration cycle. This feature is provided as a diagnostic tool only. We highly recommend that you not interrupt AutoCal while its running.
* While AutoCal is running, the V2 will display each volume step (1-70) in the process for each LDR. Thus it will go through 70 calibration steps four times in a row over the course of a full calibration cycle.
* When AutoCal is complete or shut down deliberately, the display will also shut off.
* We recommend you turn your amp off before initiating an AutoCal cycle. Physically disconnecting your cables from the V2 isn't necessary.
* We recommend you run AutoCal monthly but this is simply a recommendation and not a requirement.
