On

Used to turn on (or bypass) each of the four channel sets.

1

Bus

Sends the channel set to the stereo mix bus and headphones.

2

Drive

Outer control on each concentric pot sets the level going to the tube drive circuit.

3

Heat

Sets the B+ voltage going to the 12AX7 tube with 35, 70 or 140 volts for more or less distortion.

4

Level

Sets the output from the tube drive - acts like a master volume on a tube guitar amp.

5

Tube Drive On

Activates the tube drive – may be bypassed to compare wet versus dry or revert to the transformer coupled signal path.

6

HPF

High pass filter gently rolls off low frequency resonance below 40Hz to remove excessive bass.

7

Mix Bus

Turns on the XLR outputs. Used to adjust the summing mixer output level.

8

Headphone

Stereo 1/4" headphone output with level control.

9

Power

5-pin locking XLR connection for the external power supply.

1

Link

Stereo ¼” TRS link in/out bus combines 2 or more Space Heaters together for 16x2, 24x2 or 32x2 tube summing.

2

Stereo Sum Outputs

Provide left and right summed outputs for the most luxurious old school analog character.

3

Ground Lift

Recessed switch lifts pin-1 on the two XLR outputs to help reduce hum and buzz caused by ground loops.

4

D-Sub Outputs

25-pin D-sub is used to send all 8 transformer isolated channels back to the mixing console or workstation.

5

Send

Eight ¼” TRS balanced sends feed the post tube signal to an external processor or may be used as additional outputs for parallel processing.

6

Receive

Eight ¼” TRS balanced receive jacks bring the signal back to the Space Heater and routes it to the D-Sub output or stereo mix bus.

7

D-Sub Input

25-pin D-Sub follows the Tascam/ProTools standard and is wired in parallel to the ¼” jacks.

8

Inputs 1-8

Eight ¼” TRS balanced inputs for easy connection to the Space Heater.
