I have a USAcoustics amp(USA4050) that has alphasonik on it and it is made in the USA...so I guest this is like your amp.I was asking because last week I bought a US Acoustics USA2300f and surprisingly it came with the manual when I got it.
Thumbing through it (it covers all the US Acoustics models), I came to the page with the 2300f and it starts out "Alphasonk USA2200f, Model 600, USA2300f and Model 1000 may be used in mixed mono/stereo mode" .
Whoops!
