Set up as four stereo pairs, the Radial Engineering Space Heater design begins with a choice of 1/4" TRS or D-Sub (DB25) inputs for quick connection to a workstation.Each channel pair is 100% discrete, enabling 4 stereo sets to be used independently or be sent to a stereo mix bus with left and right outputs. To control the effect on the tube, each channel set is equipped with a separate drive control to increase or decrease the signal being sent to the 12AX7 tube and a level control to set the output. A unique Heat switch lets the user apply 25, 50 or 100 volts on the tube depending on the fidelity needed. Lower voltages starve the tube causing more distortion. On the other hand, higher voltages produce a cleaner signal.
Each stereo set is also equipped with a handy high-pass filter to help eliminate resonance and clutter. This is extremely useful for cleaning up a mix. To expand patching options, all 8 channels are equipped with separate send and receive insert jacks. The send jack works double duty as a second output with the D-Sub for parallel processing. The master section features a simple level control, headphone amp and choice of XLR or TRS outputs.
Everything is housed in a 1 RU 19" rack frame and as with all Radial products, it is made from 14 gauge steel for greater rigidity and maximum shielding. An external power brick works globally by accepting anything from 100 to 240 volts.
