Maths works great for this.\u003c\/p\u003e \u003cp\u003eThe VCA doesn’t use an exponential VCA chip or OTA like most other VCA’s, so the response curve is not a guaranteed linear or expo response and it is different with every tube used.\u003c\/p\u003e \u003cp\u003eThat is why it best to use a modulator with a variable curve and attenuation to dial in the best response.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003eIt is recommended to start with all the knobs at full clockwise\/around 5 o’clock and then work the knobs counter clockwise as you listen to the incoming audio source.\u003c\/p\u003e \u003cp\u003e3-5 o’clock seems to be about the sweet spot for all the knobs but you will find hidden sounds everywhere.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003eThe center knob controls gain, so if you bring it back too far counter clockwise that will attenuate the signal completely and no sound will come out. Center knob is usually best in the 3-5’oclock range.\u003c\/p\u003e \u003cp\u003eThe left and center knobs are part of a feedback network, so the settings between the two interact and manipulate the behavior and sound of the whole left channel in a symbiotic relationship.\u003c\/p\u003e \u003cp\u003eThey both effect the pitch effects that come from the feedback sounds.\u003c\/p\u003e","brand":"Zerosum Inertia","offers":[{"title":"Default Title","offer_id":54725906104661,"sku":null,"price":240.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1071\/1872\/3413\/files\/ZSI_TVM23_A.png?v=1787442172","url":"https:\/\/climivor.myshopify.com\/products\/zerosum-inertia-tvm23-new","provider":"CLIMIVOR","version":"1.0","type":"link"}
