Additional Details


The Otari MX-5050 Must surely have had the longest production run of any tape recorder made, through many variations on the original model. Very popular today in the secondhand market, the 5050 Is a robust machine packed with many useful features. These days, many enthusiasts are using external tape head preamplifiers As it has a very decent transport. The onboard electronics don’t quite put it in the top sound category but with many of them out there, the second hand prices are quite reasonable for what you get. A semi- professional tape deck with 10½ inch reel capacity and three motors with a total of four heads.  A sophisticated electronically controlled transport utilizing a hysteresis synchronous  or DC Servo motor, depending on the model, for the capstan drive and two motors for the reels, ensured extremely smooth  safe tape handling.
Other features included built-in splicing block, electronic 4-digit postion indicator, cueing lever for fast position location, adjustable bias and heavy-duty XLR sockets for line inputs.
Otari released the MX-5050B version in 1978, the MX5050 B III in 1990 and many other variations.
