Product Highlights
  • Single Channel
  • 4 -Band Fully Parametric
  • Passive Design
  • High- and Low-Pass Filters
  • Individual Bypass per Band

The EQF-100 from Summit Audio is a single channel, 4-band fully parametric passive equalizer that is suitable for both tracking and mixing. The unit is a hybrid processor that uses solid state technology to provide reliability, while the vacuum tube amplifier delivers tube "warmth" and provides gain to overcome any loss when cutting frequencies.

The EQF-100 features individually, hand-tuned frequencies, a silent master bypass switch and individual bypass switches on each band. Additionally, 3-position high-pass and low-pass filters can be switched into the transformerless signal path. This passive EQ is incredibly accurate, sounds wonderful, and is hand built in the USA to the most exacting standards.
