The Space Heater is an 8-channel mixer that combines 12 AX7 tubes with Eclipse transformers to produce a huge bottom end, according to the manufacturer. The 1 RU 19″ rack frame mixer offers the possibility to select the applied voltage on the tube (25, 50 or 100 volts) via a 3-position switch to make it lo-fi, mid-fi or hi-fidelity.
It further features a four stereo-pair design with 1/4″ TRS or D-sub inputs. Each channel pair is 100% discrete and is equipped with separate drive and level controls, plus send and receive insert jacks, and high-pass filter. The send jack doubles as a second output with the D-Sub for parallel processing.
On the master section there’s a simple level control, headphone amp and XLR or TRS outputs. It runs on an external power brick (100V to 240V).
