Equalizer

The Tube Tech EQ 1AM is a single channel parametric EQ designed for Mastering. It offers low-cut and high-cut filters, high and low shelve bands, and three overlapping parametric EQ bands. It contains all the features of the EQ 1A, but designed specifically for Mastering. On the Mastering version, all rotary switches are notched with 12 positions, instead of the knobs, for better control, and a much more precise reminder of the settings. It is possible to connect two 1AM EQs to process a stereo signal.
