These design enhancements widen the total frequency response while eliminating frequency drift and signal distortion across multiple octaves.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eIn operation, the filter provides the signature dark, rounded resonance characteristic of classic American ladder topologies. Cranking the resonance pushes the circuit into clean self-oscillation across a range of 10 Hz to 35 kHz. Thanks to the tight transistor matching, the self-oscillating cutoff tracks external 1V\/Oct pitch CV like an accurate, warm sine wave oscillator following a short one-minute warm-up period.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003eThe front panel includes a dual-input audio mixer that lets you sum and balance two distinct audio sources directly at the filter stage. Because ladder filters inherently drop low-frequency bass response as resonance increases, dialing in heavy self-oscillation thins out the bottom end of incoming audio signals.\u003c\/p\u003e","brand":"Analogue Systems","offers":[{"title":"Default Title","offer_id":59030477603148,"sku":null,"price":198.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/3055\/0604\/files\/analogue_systems_analogue_systems_rs_100n_lowpass_190250_1_670x1000_3bec941e-98bb-46d2-a1a8-b20faf096ee3.webp?v=1790951663","url":"https:\/\/www.schneiderskeller.co.uk\/products\/analogue-systems-rs100","provider":"SchneidersKeller","version":"1.0","type":"link"}
