The Blonder-Tongue Audio Baton, introduced in 1959, is an equaliser featuring nine octave-band controls, each capable of boosting or attenuating specific frequency ranges by up to ±14 dB. Designed for high-fidelity systems and public address applications, it offered users the ability to finely adjust frequency balance to correct system deficiencies, enhance tonal characteristics, and improve speech intelligibility.
