Product Description

The Useful Arts SFP-60 Tube Preamp is an all tube two channel mic prel, full-featured and designed to make microphone signals stand out in a mix - without the need for additional processing.

The Useful Arts SFP-60 Tube Preamp has a clear, present and edgy sound, and is specifically designed to make vocals sound forward and intimate. We accomplish this by using tubes for what they are best at – accentuating harmonics that make sound more clear and pleasing to the ear and brain in the real world.

Useful Arts SFP-60 Tube Preamp Features

  • Absolutely no signal passes through these switches, because we hate the noise that develops over time in even the most expensive switches. Instead, the front panel switches control sealed, gold-plated relays to ensure years of operation without pops and clicks.
  • The input and output levels of the triode stages of the SFP-60 are separately controllable by detented attenuators, and combined with the color control, the SFP-60 provides just over 55dB of useable gain.
  • The rear panel is simple: Gold-plated XLR connectors for the transformer-balanced inputs and outputs, a ground post, and a voltage selector for 115/230 volt operation.
  • The faceplate is milled from .190”-thick aircraft-grade aluminum for maximum rigidity, and anodized in a very dark green finish. All markings on the front panel are laser-engraved, ensuring that the unit’s appearance will not deteriorate with age.
  • The only active devices in the signal path are the three tube gain stages, consisting of 1 EF806 and 1 ECC82 per channel. We use new-manufacture JJ tubes for long life and easy replacement.
  • Each channel features an output level VU meter, which is op-amp buffered to ensure that the signal is not loaded by the meter.
  • The audio power supply features a toroidal dual-primary transformer and linear regulation for lowest noise.
  • Construction is fully modular, with gold plated connectors used throughout the audio path.

Useful Arts SFP-60 Tube Preamp Specifications

  • Each gain stage is single-ended, inherently class A.
