Sounds good. May be in mono but it's recorded directly from the module or mixer into a recorder, not using mics.
I would assume that the BK7m and the mixer includes stereo outputs.
Listening in mono, and especially thru headphones I found a bit disappointing.
Though I'm very impressed with Terry's accordion playing on the 'Bumbble Bee Rock',
the first video with Leilo & Passion has got a far more satisfyingly realistic stereo spatial sense,
and demonstrates the aural advantage of going out 'stereo' vs 'mono', even when performing live. JMO. - Scott
