8-Channel Summing Mixer & Tube Drive

Description

The Space Heater is an 8-channel tube overdrive that can be used as an analog summing mixer or as a multi-channel studio effects device, utilizing the tube circuitry for a range of effects from subtle warmth and grit to full harmonic distortion.

  • 12AX7 vacuum tube overdrive & summing mixer
  • Heat switch adjusts the voltage applied to each tube
  • Individual outputs to use as an 8-channel effects insert
  • Transformer-coupled outputs for vintage tone

Warm-up your digital tracks

The Space Heater is a high-performance summing mixer that allows you to blend tracks out-of-the-box in the analog domain, with oversized output transformers and vacuum tubes for vintage warmth and character. Eight mono input channels or four stereo pairs are available, with a heat switch on each pair to adjust the voltage on the 12AX7 tube – lower voltage settings starve the tube for a more pronounced distortion effect. Separate Drive and Level controls on each channel give you complete control over each tube circuit, providing a range of tones that allow you to fatten up digital stems or provide a distorted effect on vocals, guitars or drums.

The Radial Space Heater is an analog summing mixer and studio-grade 12AX7 tube overdrive. Its built-in features and routing capabilities allow it to be used in a number of ways. The Heat setting (plate voltage for the tube), as well as the position of the Drive and Level controls, will all have an impact on the specifications as we have shown here. The Space Heater can run clean, or run dirty.
