The second AMS Neve 1073LB. Same preamplifier as unit A: the 1073 Class A mic pre, line input, phantom, phase, and the high-pass, in a 500-series module built by AMS Neve rather than a copy. A pair of these is a small Neve front end. Two vocals, a stereo piano, a bass and a vocal, overheads if you like your cymbals with that 1073 lift. They have been used as a pair and they are listed separately so you can buy one or both. The 1073LBEQ and the empty R10 are their own listings. Smoke-free studio. It works.
