The six-band Parametric EQ is an easy to operate high-
quality algorithm supplying a precise response.

Basic Operation

• Select Band using the CURSOR keys and select filter

type using the ADJUST wheel.

• The Orange square indicates the current selected band.
• Adjustment of Frequency, Bandwidth and Gain is done

with the dedicated encoders on the front panel.

Band types:

• Lo band: Full parametric or low shelving type.
• Band 1-4: Full parametric or notch filter type.
• Hi band: Full parametric or high shelving type.

Lo Filter Range : 20Hz to 3kHz
Filter 1-4 Range : 20Hz to 30kHz
Hi Filter Range

: 1kHz to 30kHz

Parametric and Shelving filters have a Gain Range of 
+/-24dB. 

The display graphics show the frequency response for the
Parametric EQ.
