Hi,
I was wondering if there is a required or recommended warm up time for the BHA-1. When it first turn powers up it takes about a minute or two for the sound to stabilize. Before that time one channel is sometimes quite loud and turning or even just touching the volume control causes static and fluctuations in the volume. I tried both of my headphones and it occurs with both. After a few minutes it settles down and it plays as expected.
Thanks.
