LjunggrenAudio RYO ‚ÄčNAND/AND:
Discrete Resistor-Transistor Boolean Logic in 4hp .

- 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.
