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. In addition to the standard on board factory preset library the
engineer can design and store his own settings (initialized from a standard preset template) in one of the 10 available
user memory locations (see chapter 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-chain, star,
and hybrid are quickly and easily configurable with total flexibility in achieving the required system architecture. The
physical connection between the PC and the controllers is managed with CAT5e STP cable (or higher category) 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'' user 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 is for the
provision of an additional digital input module consisting of a 64 audio channel bus plus one extra channel dedicated to
remote 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 several LA8 (and LA4) 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
software.
!
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
network status, number and groups of controllers, and all the information related to the control and monitoring of the
networked controllers.
Real-time access to all settings such as mute, gain, delay, polarity, and preset can be done using the remote software
interface. A 5+1 band contour EQ system (5 fixed frequency filters and 1 parametric filter) is also available for 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'' user manual for detailed operating instructions.
