Questions: info@resistanceaudio.com ***FULLY BUILT AND TESTED WITH WARRANTY*** NOTICE: The LC4B Requires (1) Opamps to function. Please choose from the list above, or select 'No Opamps' if you are installing your own. The LC4B is not a copy or clone of anything but the filter topology is inspired by the middle bands of the old ADM 1540. With this EQ you can expect amazingly sweet musical and forgiving curves. No matter how heavy-handed you get with the LC4B its nearly impossible to ruin a track. Each of the inductor/capacitor filter networks are in the feedback loop of an OPA134 opamp. The peaking curves have a proportional Q as would be expected with an LC filter. The LC4B is not a common "swinging inputs design" like the 553F or the retired LC53A. Due to the filter topology the curves are a bit wider at lower cut/boost amounts.The LC4B sign
