Phoenix, AZ (July 28, 2017)—Useful Arts Audio has introduced the SFP-60 Microphone Preamplifier, a two-channel Class-A mic tube preamp with a variable control for second-order harmonic distortion.
Reportedly inspired by classic 1960s-era Telefunken preamplifiers, Useful Arts founder Peter Swann designed the SFP-60’s different gain stages “to utilize the tubes for what they are best for—accentuating harmonics,” he said. “The one of a kind ‘Color’ control provides an incredible amount of artistic distortion to make those mixes stand out.”
The SFP-60 features a large inductor on the output tube “instead of an inexpensive resistor,” said Swann.
“This inductor provides maximum headroom—over 60 dB of useable gain—as well as the lowest possible noise. The end result [is that] vocals and instruments are upfront in the mix.
