G a i n

Allows to adjust the amplification of the signal fed in through Inputs A and B.

Editing values are in the range +6dB ~ -30dB, with 0.5dB steps.

Note: Setting the input signal of a digital unit is particularly important, much more than on an analog unit, as any saturation of the A/D converter due to an excessively high input signal causes a typical particularly distinct noise. To achieve a good signal/noise ratio, i.e. an up-front distortion free signal, feed a signal in on the MAXI- DRIVE3.4's input and watch the INPUT LEVEL A-BLED ladders. Keep the signal quite high, but make certain the red CLIP LED doesn't light on continually.

5.3.2Input EQ

Input equalizer with 5 parametric filters.

Allows to alter the overall tone of the signal connected to the respective input.

Also called Master EQ, the equalization of the input signal effects all the outputs connected to the input and the input SUM.

This component's characteristic quality and programmability (identical to the output Equalizer) enable it to be Used so effectively and flexibly as to make the use of graphic equalizers often unnecessary.
