Red Panel by Buchla - RP-106
Model 106 – 6 Channel Mixer
The Model 106 is a 100% discrete transistor based 6 input audio mixer.
Functionally, It allows the user to manually mix 6 signals into 1 output (All), or it may be used…
Red Panel by Buchla - RP-110
Model 110 – Quad Voltage Controlled Gate
The Model 110 is 4 independent transistor based voltage controlled amplifiers behind one panel. Each VCA (or “gate” in the original terminology)…
Red Panel by Buchla - RP-156V
Model 156 – Dual Channel CV Processor
The Model 156 was likely the first “CV manipulation” tool ever available to modular synthesists. In the original 100 series environment, the 156 was used…
Red Panel by Buchla - RP-156M
Model 156M – Dual channel CV Processor (Modern)
The 156 is an accurate reproduction of the original 156, however it’s accuracy also means that it’s functionality is based entirely on the needs…
Red Panel by Buchla - RP-158
Model 158 – Dual Channel Oscillator
The Model 158 is a dual oscillator created out of an entirely discrete transistor core. It consists of two independent and identical sides each with a front…
Red Panel by Buchla - RP-180
Model 180 – Dual Attack Generator
The Model 180 is 100% discrete transistor core dual channel A/D A/H/D function generator (envelope). A trigger or gate signal greater than 2.5v at the…
The RED PANEL by Buchla (former Catalyst Audio) modules are based off of the 100 series designs originally pioneered by Don Buchla while working with the San Francisco Tape Music Center.
