4.2 - Linking multiple loudspeaker audio signals
Via the male output XLR, multiple loudspeakers can be linked together on the same signal.
With the digital input stage selected, the output is internally buffered so in essence an
infinite number of units can be connected in parallel without signal degradation. In
analogue mode, ensure that the source device can drive the combined impedance of all of
the connected loudspeakers. With most sources, 6 loudspeakers in a chain is a practical
maximum limit.
4.3 - DSP System Menu Structure
The advanced DSP card within the amplifier modules handles all crossover, EQ, gain and
limiting functions for the X3-SP and X3-DFSP. The user interface is via a backlit LCD
screen on the rear of the unit, which provides a very intuitive means of accessing relevant
information as well as recalling presets for different system configurations.
4.3.1 – LCD Display and Output Meter
The LCD display is the primary means of establishing information from the loudspeaker.
By default, the screen will display the unit name on the top line and the currently selected
program on the bottom line. Adjusting parameters via the MENU key or EDIT encoder will
change the display to reflect the current function.
The output signal meter displays the level relative to limit and clipping of the amplifier
channel which is
working the hardest. Should the meter be displaying the red CLIP LED,
reduce the system level in order to prevent damage.
4.3.2 - MENU Key
Each press of the menu key will step through the following options:
LOAD PRESET=>SAVE PRESET=>ACCESS LEVEL=>VERSION INFO
On each of these options, turning the “Edit” rotary encoder gives the user the relevant
choices:
LOAD PRESET – turn the Edit encoder to select the desired preset to recall. Press the
Edit control to select preset, and then highlight Yes/No and press the encoder again to
recall.
SAVE PRESET – turn the Edit encoder to select an unused preset location, then press the
Edit encoder to select. Preset name is then requested, which can be entered by rotating
the edit encoder for each character, and pressing the encoder to move to the next
character. Once you have finished, press the MENU key and you are asked to confirm
preset storing by selecting YES with the Edit encoder and pressing the Edit control.
“PRESET SAVED OK” will then be displayed.
