MIAD Audio LCPQ 4040MK2 Mastering Version is a four-band, single-channel inductor equalizer: fully discrete, with Carnhill transformers on the input and output. This listing is for the Mastering version.
A passive curve you cannot get from a plugin
Each of the four bands is a separate RLC section built around an inductor, and the cascaded curves stay musical even with big moves. The outer bands switch between shelving and bell, the middle bands between Hi-Q and Low-Q, and 34 fixed frequencies make settings repeatable from one session to the next. With every band off, the unit still runs through the transformers and the discrete circuit, so it works as a unity-gain line amp.
Built for mastering and mix inserts
A relay true bypass with gold-plated contacts lets you compare before and after in one move, while the per-band bypass takes out only the section you are judging. Two transformer-balanced XLR jacks drop straight into an analog chain, and a single PS 230 supply runs two units for stereo work.
