EDIT SAMPLE /

Pressing EQ shows this screen display:

Here you have access to three bands of parametric EQ. Each band has variable frequency and

gain and the ‘window’ function in the GAIN parameters down the right hand side of the screen offer

further functionality.

The ranges for each frequency are:

LF 10Hz 2000Hz (2kHz)

MF 500Hz 10000Hz (10kHz)

HF 2000Hz 20000Hz (20kHz)

Gain for all bands is variable +/-18dB

The HF and LF GAIN parameters have a ‘window’ function that allows you to select a 6dB/Octave

shelf or 12dB/Octave shelf. This will give a more pronounced effect on the LF and HF GAIN. The

MF GAIN parameter’s ‘window’ function allows you to set a variable ‘Q’ or ‘bell’ allowing you to set

the ‘width’ of the EQ effect. A setting of 0.5 is the ‘widest’ bell you can have and a setting of 20 is

the narrowest.

The OUTPUT LEVEL parameter allows you to compensate for cut and/or boost settings in the

GAIN controls. With extreme gain boost on the frequencies, be sure to reduce OUTPUT LEVEL to

prevent distortion; with extreme cut values set on the three frequencies, be sure to boost the

OUTPUT LEVEL by an appropriate amount (or use NORMALISE after the EQ processing) to bring

the sample’s level back up to optimum.

The rule of thumb is quite simple - if you boost a frequency by XdB, reduce the OUTPUT LEVEL by

the same amount. If you boost two or more frequencies by XdB, reduce the OUTPUT LEVEL by

the amount of the sum of the frequency’s boost (i.e. boost LF by 3dB and HF by 6dB, reduce

output level by 9dB). If you use a mixture of cut and boost, reduce the OUTPUT LEVEL by an

appropriate amount equal to the sum of the three frequency’s cut/boost - for example, if LF is

boosted by 3dB, MF is cut by -5dB and HF is boosted by 6dB, add the lot together and reduce

OUTPUT LEVEL by -4dB (i.e. 3 + (-5) + 6 = +4dB of overall gain therefore an OUTPUT Level of -

4dB will bring the overall signal back down to 0dB.

Of course, this only applies to a normalised signal running at optimum level. If the sample level is

less than optimum, you will just have to experiment!
