Select 2

Joranalogue Audio Design

Dual gated precision control voltage processor. Two voltage processors in 6 HP allowing input selection, voltage hold, and gated polariser/attenuverter functions, operating from slow CVs up to audio frequencies.840

Capabilities 4

Attenuverterattenuverter
Gated polariser knob per processor; can be switched to unity gain via Unity gate input.840
CV Processorcv-processor
Two independent precision gated CV processors with input selection, hold, and polariser. Operates from DC to audio frequencies.840
Sample and Holdsample-and-hold
Hold circuit with very low droop: can store a pitch-accurate voltage for several minutes.840
Voltage Mixervoltage-mixer
When A output is left unpatched, it is normalled into the B output, enabling offset and mixing applications.840

Jacks 12 (10 in / 2 out)

NameSignalVoltageDescription
Inputs (10)
CH1 Holdgate—Hold gate input for processor A. A high gate freezes the input voltage; changes on signal inputs are ignored until gate goes low.840
CH1 Selectgate—Select gate input for processor A. Low/unpatched selects left signal input; high selects right signal input.840
CH1 Signal In Lmixed—Left signal input for processor A, used by default. Normalised to precision +5 V reference when unpatched.840
CH1 Signal In Rmixed—Right signal input for processor A. Normalised to 0 V when unpatched. Selected when SELECT gate is high.840
CH1 Unitygate—Unity gate input for processor A. When high, disables the polariser knob and forces unity gain output.840
CH2 Holdgate—Hold gate input for processor B. A high gate freezes the input voltage; changes on signal inputs are ignored until gate goes low.840
CH2 Selectgate—Select gate input for processor B. Low/unpatched selects left signal input; high selects right signal input.840
CH2 Signal In Lmixed—Left signal input for processor B, used by default. Normalised to precision +5 V reference when unpatched.840
CH2 Signal In Rmixed—Right signal input for processor B. Normalised to 0 V when unpatched. Selected when SELECT gate is high.840
CH2 Unitygate—Unity gate input for processor B. When high, disables the polariser knob and forces unity gain output.840
Outputs (2)
CH1 Outmixed—Processor A output (A output). If left unpatched, its signal is mixed into the B output.840
CH2 Outmixed—Processor B output. Receives mixed signal from processor A when A output is unpatched.840
