Ostensibly for \"Howl Reduction\" but capable of some very interesting effects. Essentially, unlike a pitch shifter, a frequency shifter does not preserve the harmonic relationships in the input signal. In practice this means the output quickly starts to deviate from what is going in and extra tones are added which then interact and interfere with the source producing new harmonics and drones. As you can perhaps imagine this is what we like about these units, and why we've had one in the studio for years...\u003c\/p\u003e\n\u003cp\u003eServiced and working well.\u003c\/p\u003e\n\u003cp\u003eMono input and output via 1\/4\" jacks on the rear.\u003c\/p\u003e","brand":"Soundgas","offers":[{"title":"Default Title","offer_id":64581019926905,"sku":null,"price":1950.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/7796\/8739\/files\/Surrey_Electronics_Spectrum_Shifter_BC1948.png?v=1789476182","url":"https:\/\/soundgas.com\/products\/surrey-electronics-spectrum-shifter-bc1948","provider":"Soundgas","version":"1.0","type":"link"}
