The Tone Control Function
The unit has functionality to adjust frequency response in accordance with the location and environment in which it is placed.
Adjustment is performed using a combination of the three knobs on the rear panel.
The unit is shipped with settings to provide a flat response in an anechoic room. Please adjust the settings to match the environment
in which you place the unit.
 Low EQ
A shelving filter is used to adjust the frequency response in the low frequency range. You can choose from +2 dB, 0 dB, –2 dB and –4 dB.
Use if the placement environment of the unit is lacking in the low frequency range, or if reflection from walls etc. is causing the low
frequency range to become too strong.

A notch-filter is used to adjust frequency attenuation in the approx. 100 Hz to 200 Hz range. You can choose from 0 dB, –1 dB, –2 dB
and –4 dB.
Use if the effects of a control console or table are making the above range too strong.
 High EQ
