Main buss or mastering EQ for your low’s, mid’s and high’s. Our new TK-lizer is a Baxandall type of EQ, high and low bands are selectable between shelving or bell, very useful for fine tuning of your low’s, mid’s and high’s. The EQ also has a built in M/S function which lets you process the mid and side signals separately. You can also affect the stereo width of your music by using the level controls in M/S mode. The three bands are based on the legendary Baxandall circuit from the 50’s. Spec: Dual mono 3-band Baxandall style EQ. 12dB octave high pass filter (the highest HPF frequency 100Hz which is for mono-ing bass in M/S mode, this frequency can easily be change by the customer). All controls are stepped for repeatability and easy channel tracking. Broad Q. High and Low band selectable between shelving or bell. Built in M/S function.
