I play and sing. I play acoustic as electric guitars and I had de need to mix voice too.
The experience with the Palmer Pan 48 is awesome. It is pretty transparent, like there is nothig between the sources and the amp. The sound is crisp and clear, letting the amp do its job without any coloration.
I encoroughly recommend it.
In my case I don't need batteries so, the simple power cable does its job. I guess simplicity in this regard may help the engineering and thus the sound, but that's just an impression.
great product
thx!
