1.0 INTRODUCTION

The EQX20 is a two channel 3 band Parametric Equaliser which can also be configured as a single channel 6 band unit. Each band offers variable Frequency, 15dB cut and boost and variable Q (Bandwidth).

Having all parameters fully variable makes the EQX20 a powerful tool capable of a range of effects from subtle fine tuning through to radical tonal changes.

Each channel has a high pass filter switch intended to remove subsonics such as stage noise and tightening bass sounds.

The facilities provided by the EQX20 are summarised as follows -

•2 Channel 3 band or single channel 6 band parametric EQ

•Wide frequency sweep (40:1) on each band

•Q variable between 12 (1/12th octave = 1 semitone) to 0.3 (3 octaves)

•±15dB gain on each band

•High pass filter on each channel

•Bypass switching on each channel

•Balanced inputs on XLR and TRS jack

•Balanced impedance, ground compensated outputs on XLR and TRS jack

•+4dBu and -10dBV input and output levels

•Low noise and distortion

Typical applications for the EQX20 include -

•Audio sweetening

•Precision equalisation

•Feedback elimination

•Hum, subsonic and noise removal

•Making a compressor frequency conscious

•Special effects

•Enhancing the EQ on a mixing console
