Moon Modular - SW M-525 Reversible Attenuators

The M-525 REVERSIBLE ATTENUATORS module features four active bipolar attenuators for audio signals and control voltages. 0 position = no output signal present +10 position = output signal equals input signal (unity gain) -10 position = output signal equals input signal (unity gain), but inverted The four input jacks are "chained", input 1 is internally connected to +10/5 volts (switchable) if nothing ist patched. So the module doubles as single to quad variable voltage source.
