{"product_id":"4ms-percussion-interface-and-expander","title":"4MS PERCUSSION INTERFACE AND EXPANDER","description":"\u003cp\u003eConverting 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.\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eBasic Features:\u003c\/span\u003e\u003cbr\u003eSensitivity knob, Low\/Medium\/High gain switch, and clipping LED\u003cbr\u003eSustain control to prevent misfires, increase gate length, and control the envelope\u003cbr\u003eEnvelope decay control\u003cbr\u003eNon-inverted and inverted envelope outputs, useful for side chaining\u003cbr\u003eFour envelope outputs: two attenuated with independent attenuators, and two non-attenuated\u003cbr\u003eEnvelope following or generation modes\u003cbr\u003eGate output for clocking sequencers or any unit with a clock or trigger input\u003cbr\u003eCompatibility with drums, samplers, microphones, drum machines, etc.\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eAudio Inputs:\u003c\/span\u003e\u003cbr\u003e1\/8” [3.5mm] on PI main module, and 1\/4” [6.35mm] on PI Expander\u003cbr\u003e100k input impedance, AC-coupled\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eAudio Outputs:\u003c\/span\u003e\u003cbr\u003eVoltage range: -10.4V to +10.8V, DC-coupled\u003cbr\u003e1k output impedance\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eGain Characteristics\u003c\/span\u003e\u003cbr\u003eGain range: \u0026lt; -100dB to +54dB (500x)\u003cbr\u003eClip light turns blue when signal (post-gain) exceeds 2.5Vpp\u003cbr\u003eGate is triggered when signal (post-gain) exceeds 6.3Vpp\u003cbr\u003eClip light flashes red when signal clips on Audio Out jack (exceeds +10.8V)\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eGate Out Jack\u003c\/span\u003e\u003cbr\u003e1k output impedance\u003cbr\u003e+8V gate\/trigger signal\u003cbr\u003e6ms – 0.5s pulse width\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003e+ Env Out jack\u003c\/span\u003e (jack on PI main module)\u003cbr\u003e1k output impedance\u003cbr\u003e+9V peak (sustain), -60mV resting (off)\u003cbr\u003e15ms attack time\u003cbr\u003e70ms – 6s exponential decay time (1% of peak voltage)\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003e- Env Out Jack\u003c\/span\u003e (jack on PI main module)\u003cbr\u003e1k output impedance\u003cbr\u003e+9V resting (off), -150mV peak (sustain)\u003cbr\u003e15ms attack time\u003cbr\u003e70ms – 6s exponential decay time (1% of peak voltage)\u003c\/p\u003e\r\n\u003cp\u003e\u003cspan\u003eEnv.
