The BQ-A is a digital emulation of a classic British equalizer from the 1970s, delivering a broad spectrum of tonal shaping possibilities. This four-band EQ features mid frequency sections with peaking filters and high and low frequency sections with shelving filters, each offering a selection of preset frequency centers. Users can boost or cut frequencies by up to 15 dB per band, making it an essential tool for precise audio sculpting across a wide range of music production tasks.

In addition to its core equalization capabilities, the BQ-A includes multiple high pass and low pass filters that can be combined in unique ways thanks to independently switchable filter settings. These filters provide further control over the audio spectrum with distinct slope characteristics, enabling creative and unconventional filtering effects. The EQ supports Stereo, Mid, and Side processing modes, allowing detailed spatial adjustments and enhancing mix clarity.

The BQ-A extends the character of vintage analog hardware by blending it with the flexibility of modern digital processing. It features an option to toggle analog-style saturation on or off, offering either warm coloration or clean digital sound depending on the user’s preference. This combination of classic tonal qualities and advanced routing options makes the BQ-A a professional-grade equalizer suitable for a variety of mixing and mastering applications.
