4MS PERCUSSION INTERFACE AND EXPANDER

Converting microphone, instrument, line and modular signals in to CV and clock/gate signals, the PI and PI Expander are suited for synchronizing sequencers or other modules to the rhythm of an audio track or live percussion. The modules can simultaneously be used as a pre-amp for microphones or line-level signals, while generating inverted envelopes useful for side-chaining. The PI module contains all the core functionality and can be used without the Expander to conserve space. The Expander requires the main PI modules and adds three gain stage options, a modular-level audio output jack, a 1/4" (6.35mm) input jack, and envelope attenuation capabilities. Basic Features:Sensitivity knob, Low/Medium/High gain switch, and clipping LEDSustain control to prevent misfires, increase gate length, and control the envelopeEnvelope decay controlNon-inverted and inverted envelope outputs, useful for side chainingFour envelope outputs: two attenuated with independent attenuators, and two non-attenuatedEnvelope following or generation modesGate output for clocking sequencers or any unit with a clock or trigger inputCompatibility with drums, samplers, microphones, drum machines, etc. Audio Inputs:1/8” [3.5mm] on PI main module, and 1/4” [6.35mm] on PI Expander100k input impedance, AC-coupled Audio Outputs:Voltage range: -10.4V to +10.8V, DC-coupled1k output impedance Gain CharacteristicsGain range: < -100dB to +54dB (500x)Clip light turns blue when signal (post-gain) exceeds 2.5VppGate is triggered when signal (post-gain) exceeds 6.3VppClip light flashes red when signal clips on Audio Out jack (exceeds +10.8V) Gate Out Jack1k output impedance+8V gate/trigger signal6ms – 0.5s pulse width + Env Out jack (jack on PI main module)1k output impedance+9V peak (sustain), -60mV resting (off)15ms attack time70ms – 6s exponential decay time (1% of peak voltage) - Env Out Jack (jack on PI main module)1k output impedance+9V resting (off), -150mV peak (sustain)15ms attack time70ms – 6s exponential decay time (1% of peak voltage) Env.
