The corresponding combination of weighted amplifiers then in turn adjusts the volume. The volume sensor mechanism is made of a massive aluminum block extruded and finished with utmost precision. The knob provides an exquisite tactile feel when rotated and ensures extremely accurate position detection. The entire mechanism is supported by a floating suspension using insulators, which also allows extremely quiet motor-driven operation when the remote commander is used.\u003cbr\u003e\u003cmeta content=\"text\/html; charset=utf-8\" http-equiv=\"content-type\"\u003e\u003c\/p\u003e\n\u003ch4\u003eFull Mono construction\u003cbr\u003e\n\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cp\u003e\u003cmeta content=\"text\/html; charset=utf-8\" http-equiv=\"content-type\"\u003e\u003cmeta http-equiv=\"content-type\" content=\"text\/html; charset=utf-8\"\u003eInside the preamplifier, circuits and components are securely mounted to a sturdy 8 mm thick aluminum frame and kept completely separate for the left and right channels.
