4.2 Adjusting the input signal

(example)

It is much more important to set the input signal of a digital unit than that of an analog unit, because excessively high input signals will make any saturation of the A/D converters cause a typical particularly distinct noise (high level square wave).

Proceed as follows:

Keep the MAXIDRIVE3.4 outputs in MUTE status (LEDs light on).

Feed a signal in on the MAXIDRIVE3.4's input and watch the INPUT LEVEL A-BLED ladders.

To obtain a good signal/noise ratio, i.e. an up-front distortion-free signal, keep the signal quite high, but make certain the red CLIP LED doesn't light up continually.

Find out the output level setting for your mixer (or other unit) and connect it to the input of the MAXIDRIVE3.4.

Adjust the MAXIDRIVE3.4 input gain if necessary:

Press the MODE key until the EDIT menu LED lights up.

Use the PREV and NEXT keys to go to the Input Gain page:

Press ENTER.

The display will show the INA Gain or INA&B Gain page (according to the configuration and other utilities loaded in the memory):
