soundtrane Report post #1 Posted June 25, 2017 External Powering option for Mixpre-3 and Mixpre-6 * Locking DC connector * Can take up to 17V DC input (meaning Li-Ion at full capacity) * Can use AA batteries despite the modification - if necessary when external powering is not possible. As of now - cannot put in EXT PWR with AA batteries in the sled both at once -until i find a way to isolate the direct physical connection between the sled and the recorder... -vin Share this post Link to post Share on other sites
Lucas Report post #2 Posted July 13, 2017 That looks like a neat solution! Would you mind sharing some info on the internals of your box, for example what converter did you use? Share this post Link to post Share on other sites

Re isolation: Is this because even if the 2 power sources are wired in parallel the external source would give the AAs a problem? Share this post Link to post Share on other sites

stefanosound Report post #5 Posted August 14, 2017 ...if you put a piece of plastic between two battery you open the chain... and you can leave the battery inside ready to be used if you loose the external energy. In add you should cut the external power with a switcher, oterways the regulator remain in parallel at the battery and you can loose energy. Share this post Link to post Share on other sites
