RYO NAND/AND Gates Dual Discrete Logic Eurorack synthesizer modular Module

Dual discrete resistor-transistor NAND/AND logic gate

• directly modelled on RTL digital logic gate designs pioneered in the 1950s used in computing equipment throughout the 50s and 60s.
• can be used as audio waveshaper/distortion.
• The NAND/AND module can be patched as:
  two NOT gates,
  one NOT gate and one 2- or 3-input NAND/AND gate,
  one 2-input NAND/AND gate and one 2- or 3-input NAND/AND gate, or,
  one 4-input NAND/AND gate.
• All analogue circuitry.
• slim 4HP footprint.
• compact 45mm Depth (with power cable attached).
• low power draw: 28mA +12V / 0mA -12V / 0mA +5V.
• Works for audio as well as CV.
• Fast responding CV inputs allow up to audio rate operation.
• The inputs on gate one are normalized in a 1>2>3 fashion for patching.
• The input on gate two are also normalized 1>2,
• the AND out from gate one is normalized to input 1 on gate two.
• signal indicator LEDs on every input and output.
• can accept input signal to +10V peak.
