There is a switch to choose either INT or ref. The INT oscillator frequency goes from 0 to 1kc.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe CV input is sent to the INT oscillator only and can be varied with its attenuverter.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eFM receives an audio input and can be applied to INT. The amount of modulation is determined by the attenuator knob.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe resulting shifts are present at the “dierence” and “sums” outputs. There are two identical outputs for each of these.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe “ring” double output is a pure ring modulation determined by the incoming signal and ref.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe CV input and its attenuverter modulates the sweep from “zero-amplitude-ring.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe bottom MODULATION section applies to the “variable” double output.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe knob manually sweeps from zero (the pure incoming “signal”) through amplitude modulation ending in pure ring modulation. When this knob is set fully CW to “ring” it is the same signal as the “ring” outputs.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Balanced Modulator receives an audio signal at the “signal” input. This can be thought of as the carrier while the “ref.” input receives a dierent audio signal (the modulator).\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe 285t Frequency Shifter is an interesting module for processing audio samples or live voice input via a microphone through the 207t Mixer\/Preamplifier module. The \"sum\" and \"dierence\" outputs from the 285t can then be routed to the 292t Quad Lopass Gate, creating dynamic tone shaping. By further splitting the processed signals into the left and right channels, this setup allows for a rich stereophonic eect.\u003c\/p\u003e","brand":"TIPTOP AUDIO","offers":[{"title":"Default Title","offer_id":43945346498733,"sku":null,"price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/files\/Frequency-Shifter-Model-285t-768x1082.png?v=1732117813","url":"https:\/\/www.detroitmodular.live\/products\/tiptop-audio-buchla-285t-frequency-shifter","provider":"Detroit Modular","version":"1.0","type":"link"}
