LOUDSPEAKER MANAGEMENT PROCESSOR
3. FAST SYSTEM CONFIGURATION
First of all switch off the equipment, carry out the audio and power connection from the various components of your sound
system. After connecting all audio cables, connect the mains cord and only at the end switch on the LM260.
The display will show
Initializing...
while all outputs are muted for some seconds. Meanwhile, the system will restore the exact operating conditions at the time
of switching off.
Then the system will enter into default status, showing last loaded Preset name:
FIVEO LM260
DEFAULT PRESET
Set all the LM260 outputs in MUTE status (LEDs lit) by pressing the relative keys.
Load the Factory PRESET containing the configuration.
Preset Menu
Pressing MENU once the display will show you the last loaded preset, for example:
Load: 1
DEFAULT PRESET
Following examples are based on DEFAULT PRESET; for further details, please read following paragraphs. Pressing again
MENU you recall the following screens:

Adjusting the input signal
It is much more important to set the input signal of a digital unit than that of an analogue unit, since excessively high input
signals will make any saturation of the A/D converters cause a particularly distinct noise (high typical level square wave).
Proceed as follows: Keep the LM260 outputs in MUTE status (keys lit). Feed a signal in LM260 INPUTS and check 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 flash continuously.
Find out your mixer (or other sound source) output operating level and check LM260 input LEDs.
To adjust the input gain, please check “In 1 Gain” and “In 2 Gain” settings. If necessary reduce it counter-clockwise rotating
the DIAL, please note that minimum step is 0.25dB Using the DIAL to change the gain value, check the level of the signal
on the INPUT LED ladders until the ideal values are reached.
Then use the NEXT key to access to “In 2 Gain” page (it will depend on the configuration; linking input Gains, you just need
to set one Gain value). If necessary, repeat the settings as explained above.
At this point, the first custom setup can be prepared. The detailed specifications of each parameter are shown in the respective
paragraphs of the manual.
