FeaTUre SeT
1.
DrIVe:
Controls the input level of the tube circuit.
Increase the drive to allow more signal to enter the
tube adding saturation and warmth.
2.
HeaT:
3-position switch selects between 35, 70 and
140 volts at the tube. At 35V the tube is starved for
voltage creating more distortion.
3.
LeVeL:
Controls overall output level. Depending on
the amount of drive added, the level control can be
adjusted to achieve an optimal signal level.
4.
HI-CUT:
The low-pass filter is used to tame
excessive harmonics when using heavy distortion.
5.
eQ:
Assigns the filters pre or post tube circuit, or
turns them off completely.
6.
LOW-CUT:
Variable high-pass filter from 5Hz to
500Hz used for reducing unwanted low frequencies.
7.
ON:
Engage or bypass the circuit completely.
8.
OMNIPOrT:
Available when used with the
Radial Workhorse, the Omniport accesses a hi-Z
instrument input.
9.
POWer aSSIGN SWITCH:
Lets you toggle the
input supply from the positive or negative rail. This
enables multiple Space Heaters to be used together
without power sag.
10.
12aX7 TUBe:
The Space Heater 500 employs a
select low-noise 12AX7 tube with a non-radiating
140V charge pump to deliver the performance of a
high voltage tube preamp.
