I used one for years MX5050 8 track. Multitrack 1 / 2 inch. Inputs and outputs on XLR symtriques. 38 or 19 cm / sec. Rglages indpendants of prmagntisation, HF and LF compensation, level of recording and playback on the head of sync and playback. I bought it in 1987 and I sold it in 1992. He worked hard for 5 years trs. I made my arms in sync with an Atari ST1040. Silent sound excellent. It was blowing but not too much thanks 4 pairs of dbx150. The sound coming out n'tait not the same as the one entered. C'tait particulirement sensitive at low frequencies. In short, a machine that had the characters and ds when required to be understood and cuddly. Sr Although I largely prfre my current Dtr. However, sometimes when j'prouve difficulties of playing a bass, I think that with 5050, would sound a dj. But it's not just the bass in for a title and 23 other tracks, I am a winner.
