EQ-6S Stereo Equalizer


The High Voltage Audio EQ-6S is a six band, mastering grade stereo equalizer. With its precision built stepped switches (0.5dB steps -/+ 5.5dB), the EQ-6S provides perfect stereo tracking and ease of recall.

The equalizer is a broad-stroke, sound sculpting device with 5 fixed frequency bands and a switchable high shelf "Presence Filter".

Unlike the majority of equalizers on the market, the EQ-6S is a dedicated stereo equalizer. With one set of controls under the hood, the EQ-6S is incredibly quick and easy to dial in. Compared to its rivals, the EQ-6S boasts unrivaled control, precision, noise performance and value.
