LEM DX 26 PLUS - Adjusting the Input Signal

13
Adjusting the input signal
Setting the input signal of a digital unit is particularly important, much more than with an analog unit, as
any saturation of the A/D converters caused by excessively high input signals cause a typical particu-
larly distinct noise (high level square wave).
Proceed as follows:
+ Keep the DX 26 PLUS outputs in MUTE status (LEDs lit).
+ Feed a signal in on the DX 26’s input and watch the INPUT LEVEL A-B LED 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.
+ First of all, find the output level setting for your mixer (or other unit) connected to the input of the DX 26
PLUS
+ Then adjust the DX 26 PLUS 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 shows the INA Gain or INA&B Gain page (according to the configuration
and other utilities loaded in the memory):

Use the DIAL to change the gain value and watch the level of the signal on the LED ladders until the
ideal values are reached.

Then use the PREV and NEXT keys to access the INB Gain page (if there is one – this depends on the
configuration and the other utilities loaded in the memory).
Repeat the settings as explained above.
