The Dangerous Music BAX EQ Stereo Shelving Equalizer is designed by mastering engineers for recording, mixing, and mastering. The unit is based on Peter Baxandall's classic tone control designs and allows you to precisely shape your sound. The back of device features a pair of 3-pin XLR inputs and a pair of 3-pin XLR outputs.

The front of the unit includes stepped control knobs for a 12 dB/octave low-frequency cut filter for reducing rumble from infrasonic content. A broad bandwidth shelving EQ control allows you to adjust several octaves at the same time with minimal phase delay, and stepped controls in 0.5 dB increments for left and right low-frequency levels enable you to discretely correct any stereo channel imbalances.

Similarly for the treble, the EQ includes stepped control knobs for an Ultrasonic cut filter, a high-frequency shelf filter for adjusting several octaves at once, and independent left and right high-frequency level controls for correcting stereo signal imbalances. When set to "Out", the cut filters are removed through a relay bypass for A/B comparisons of the signal with and without the cut equalization. A hard-wired engage button allows you to bypass all of the equalization hardware from the circuit for true A/B comparisons of the signal with and without the EQ.
