RoXonix BAX-EQ Stereo Baxandall Equaliser

BRITISH HANDBUILT STUDIO GEAR 

A Baxandall EQ is a special type of shelving equalizer based on a circuit developed by English electrical and audio engineer Peter J. Baxandall in 1950.
Baxandall shelves have a very wide and gentle Q-factor which gives them two rather unique properties: first, the phase shift is greatly minimized and spread over a wider area than with conventional parametric shelves, and second, in their useable frequency ranges most of the affected audio frequencies fall under the rising or falling parts of the Baxandall EQ curve. By the time a BAX shelf flattens out it’s so high or low that it’s beyond the limits of the human hearing range. Taken together, these properties have the effect of giving BAX shelves a very transparent and musical sound which enables users to make boosts and cuts without imparting negative artifacts into the signal, resulting in a wide, open sound that enhances the source’s sonic character that’s already there rather than imparting its own sonic character. Fine adjustments can be made to the final stereo mix without the complexity of other types of equalisation which can alter the structure of the mix. If you’re looking to add some presence, sheen, gloss, air, etc. to the high end without things getting harsh, or you need to add some heft or weight to the bottom without things getting boomy or muddy, Baxandall shelves are a great choice.

The RoXonix BAX-EQ Baxandall Stereo Equaliser is a handbuilt stereo 2-band shelving EQ. It features low noise variable gain input and output Op-Amp circuits with front panel stereo controls utilising sealed low noise potentiometers to enable precise adjustment of the stereo line level signals. High quality WIMA capacitors are used in the Baxandall EQ circuit ensuring the best performance from the equaliser.

The RoXonix BAX-EQ features a 8K/12K switch which shifts the high frequency curve position. The switch position represents the frequency of the shoulder of the Baxandall curve. Using the 12K position results in a more subtle, 'airy' top-end.
Also included is a EQ bypass switch so A/B comparisons can be easily made.
