I have had my A10 for a little over 2 months. Here are a few observations...
The following paragraph contain content regarding
recording. If this offends your sensibilities then avert your gaze or
simply skip.
I am currently running a set of AT853a cards (darktrain modded) MIC IN (yes mic in) into the A10. I like to stack and have
yet to brickwall with this configuration. Would a pre-amp / bb serve me better? Perhaps. But having the extra connectors and
gear and battery charging issues to contend with is a drawback for me. Security at venues where I live is getting to be more of a
pain (walk thrus + wand, walk thrus + patdown, etc...). Spare me the "Back in my day I got a Revox into Led Zep at The Forum..."
I just don't want to contend with all that crap. This thing (the A10) is tiny and thwarts just about every walk thru and wand I have
encountered even with my mics.
Regarding the battery capacity...
01. The unit will easily record at least 4 hours at 24/48 with Bluetooth engaged.
02. I haven't run a battery "rundown" test yet because I haven't seen a point in doing so. Someone else, please feel free to do so and post their results.
I still am curious.
03. The unit can be simply charged using a cellphone external battery charger. Simply extend the USB dongle on the A10 and plug it into the USB port
(technically a receptacle) of the battery or USB cigarette lighter. Unlike the M10, you can access all record and playback functions while the battery
is charging.
Regarding the battery longevity...
01. If I have to replace the unit in 3 years or so, so be it. The benefits (size, capacity, built in battery, micro sdhc support, and most importantly the
sound quality) outweigh this IMHO.
02. I figure it will be quite sometime before this occurs. Hopefully 32bit float will find its way into the lineup by then.
I hope that this helps.
