Programmable three-way splitter

Programmable three way splitter from Mission Engineering® (Expressionator®)

One expression input is split into three outputs.

Outputs can be set to 0 - 5 control voltage or 20 Kohm resistance

Output is normal polarity (TRS)
Adapter available to convert to rheostat (TS)

A normal polarity (TRS) expression pedal is connected to the input .
The expression pedal can then control the three outputs simultaneously or individually

Variable taper includes linear and anti-logarithmic

Sweep is forward or reverse

Automatic oscillator includes saw tooth and square (wave repeats 8 times within a single sweep)

Individual minimum and maximum depth positions for each output channel

Dimensions 112 x 66 x 46 (mm)

Programmable two-way splitter

Programmable two way splitter from Oz Inventions®

One expression input is split into two outputs.

Outputs can be set to 0 - 4 control voltage or 10 Kohm resistance

Outputs can be configured for normal polarity (TRS), reverse polarity (RTS) or rheostat (TS)

A normal polarity (TRS) or reverse polarity (RTS) expression pedal is connected to the input. The expression pedal can then control the two outputs simultaneously or individually

Taper is linear

Sweep is forward or reverse

Individual minimum and maximum depth positions for each channel

Individual on/off switches for each channel

Expandable. Multiple units can be strung together to provide additional outputs

Enclosure 112 x 60.5 x 31 (mm) (standard 1590B enclosure)

Two Position Switchable Expression

Two position switchable expression box from Saturnworks Pedals®

Two potentiometers set individual positions within the sweep

A latching switch selects between the two positions

Individual LEDs indicate which position has been selected

Momentary switch version

TRS and TS version

Requires no power for expression (power only required for LEDs

TRS Stereo Polarity Reversing Adapter

1/4" TRS Stereo Polarity Reversing Adapter from Ramble FX®

Reverses the polarity of a 1/4" TRS stereo cable. The TIP and RING of the TRS connectors are reversed. The SLEEVE remains the same. It can be used to connect two devices that would otherwise be incompatible.

e.g converts Zoom (RTS) to Fractal (TRS) or the vice versa
