The LaChapell Audio 983M Tube Preamp is a half rack sized single channel tube preamp that is perfect for small studios, podcasting, voice overs, and session musicians.

Along with the 983S MK2, the 983M is the first preamp to feature True48, a phantom power supply that provides a consistent 48V for phantom powered mics. Current 48V supplies dip in voltage as the source load changes (such as periods of high transients on many mics). True48 evens out the voltage supply, giving mics greater headroom and a smoother, less distorted response.
