BAXY - Professional EQ 500 Series Format


BAXY is a professional equaliser designed to fit 500 format compatible racks.

Its development was inspired by Peter J. Baxandall's famous design, known for its musicality in mixing and mastering setups all around the world. The centerpiece of BAXY's circuit is a JFET transistor that closely resemble the working principle of the valves, the original active components used by Baxandall.

BAXY features 5 different selectable frequencies for both the LOW and HIGH part of the audio spectrum, and cut/boost them up to 10dB in 21 steps. This is to have more control in a stereo setup.

To expand your possibility, BAXY provides a second order HPF and LPF, both with 2 selectable frequencies. Via a switch directly placed on the circuit board, the 2 selectable frequencies can be further adjusted to best suit a mixing or mastering setup.

Also, a bypass switch is provided to quickly compare the original and EQ'ed audio material.

With its superb sounding character, BAXY is a must needed tool in your arsenal...don't miss it!

Mixing and Mastering Setup

One of BAXY's great features it is that it allows the user to set the LPF and HPF default frequencies, switchable by the front panel toggle switch, to either a setup best suited for mixing or mastering.

This is due via two DIP switches,SW6 and SW7, mounted on the printed circuit board. A silkscreen is also there to have a visual feedback of the selected frequencies.

Flick SW6 to the left (towards the “1/2” text) to set the HPF frequencies to 18/40Hz, move it to the right (towards the "ON" text) to set them to 30/50Hz.

Similarly, move SW7 to the left to set the LPF frequencies to 12/17KHz, flick it to the right to set them to 16/22KHz.
