S.M.S.L. SP200 with a channel imbalance on the XLR connectors, but works just fine and within factory spec on a RCA single end side input. The amplifier isn''t internally balanced, so the best performance will always be on the RCA input anyway, since it doesn''t have to do conversion from the XLR. New power cord and 6.35mm adapter, and also a 10ft RCA cable which is very high quality. Amazon has the best branded cables for audio. We ship same day on orders before 12pm EST. Will be bubble wrapped and carefully boxed. Offers are accepted and you''ll get an instant response by the Mercari automatic system.
