Space Heater Specifications

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.
