5.2.5 User interface
The front panel user interface features quick access functions for the 2 inputs and 4 outputs. The encoder wheel gives
instant access to the user menus and the LCD display offers real time visualization of the system parameters.
Navigation through the menu pages is fast and intuitive. Beside the standard on board factory preset library the
engineer can design and store his own settings (initialised from a standard preset template) in one of the 10 available
user locations (see part 7).
5.2.6 L-NET Remote Control Network
The proprietary L-NET network uses a high speed data transfer of 100 Mbit/sec for real time monitoring and control of
each individual LA controller within a network of up to 253 units. Multiple network topologies such as daisy-chaining,
star, and hybrid, are quickly and easily configurable allowing for total flexibility in achieving the required system
architecture. The physical connection between the PC and the controllers is managed with CAT5e STP cable and the
I/O Ethernet sockets located on the rear panel of the controller require industry standard RJ45 connectors. The use of
a universal Ethernet switcher is recommended for specific network topologies.
Note: Please refer to the ‘‘LA NETWORK MANAGER’’ software manual for detailed operating instructions.
5.2.7 Digital Audio Network
A slot located on the rear panel is designed to accept an optional L-DGA card (digital audio network). The slot allows
for the provision of an additional digital input module consisting of a 64 audio channel bus plus one extra channel
dedicated to control and monitoring. The extremely low and predictable latency of this technology combined with
proven real world reliability delivers stable and predictable results in all sound reinforcement applications. The L-DGA
card also allows for cascading of several LA4 (and LA8) using the same type of cable as for the L-NET remote control
network. The signal routing on the digital audio bus into any LA controller can be operated from the LA NETWORK
MANAGER application.
This option will be available as a future development.

LA NETWORK MANAGER PC Software
L-ACOUSTICS ® LA NETWORK MANAGER provides network control and monitoring of both LA4 (and LA8)
controllers from a PC Windows ® -operating system. The multiple window display gives an overall visualization of the
network status, number and groups of controllers, and all the information related to the control and monitoring of the
networked units.
Access to all settings such as mute, gain, delay, and preset can be done via the remote software interface. An EQ
contour is also available allowing quick and easy tonal balance of the loudspeaker system.
LA NETWORK MANAGER also features system stand-by and initialization control in addition to comprehensive visual
monitoring of the audio signal paths and quick detection of any faults in the attached network.
Note: Please refer to the ‘‘LA NETWORK MANAGER’’ software manual for detailed operating instructions.
