A chain of knobs with selectable ranges to offset and scale input signals.

Each row of controls is a channel that applies a selected function to its input signal.

Each channel’s input is normaled to the output of the channel above it.

Controls

Each channel includes the following controls.

• ADD / MULT: Selects the function to apply to the input signal.

  • ADD offsets the signal by adding the selected amount to it.
  • MULT scales the signal by multiplying it by the selected amount.

  This switch also selects an appropriate set of ranges for the function. See the RANGE button, below.

• KNOB: Selects the amount to offset or scale the input signal.

• RANGE (button): Selects the range of the knob.

  The ranges depend on the function selected by the ADD / MULT switch. For each function, this button cycles through several ranges.

  • ADD ranges:
    • 0–5
    • ±5
    • 0–10
    • ±10
  • MULT ranges:
    • 0–1 (attenuator)
    • ±1 (attenuverter)
    • 0–2 (gain)
    • ±2
    • 0–5
    • ±5
    • 0–10
    • ±10

Ports

Each channel includes the following ports.

• IN: The input to the function.

  Each IN port is normaled to the OUT port of the channel above it. That is, if a channel’s IN port is not connected to a wire, the channel takes its input from the OUT port of the channel above.

• OUT: The output signal from the function.
