7.9.1 NETWORK ADDRESS control

It is possible to connect up to 253 LA4 and LA8 amplified controllers in multiple network topologies via the proprietary

L-NET Network. Each controller has to be identified within the network by its IP address (Internet Protocol address).

Modify the IP address by applying the following procedure (see also Figure 29):

1. Select the NETWORK ADDRESS control page by rotating the encoder wheel and press the OK key or

the encoder wheel to validate (or press the ESC key to cancel and return to the last menu).

2. Set the desired IP address value (last 3 digits) by turning the encoder wheel (obtain 10-step resolution by

simultaneously pressing the encoder wheel).

The unit IP address format must be 192.168.1.

 with last number selected in range 001:253.

The IP addresses of the computer (192.168.1.254) and all units must be different from each other.

3. Press the OK key to validate the IP address setting (or press the ESC key to cancel and return to the last

menu).

As an example, in Figure 29 the IP address has been modified from 192.168.1.110 to 192.168.1.123.

7.9.2 INPUT MODE control

The INPUT MODE control page is for selecting between ANALOG and AES/EBU inputs. In ANALOG input mode the

IN A and/or IN B inputs (ANALOG panel on Figure 8) must be connected to an analog audio source. In AES/EBU

input mode the AES/EBU IN input (AES/EBU panel on Figure 8) must be connected to a digital audio source providing

signal in any of the following formats:

• Standard: AES/EBU (AES3) or coaxial S/PDIF (IEC 60958 Type II).

• Sampling frequency: 44.1, 48, 64, 88.2, 96, 128, 176.4, or 192 kHz.

• Word length: 16, 18, 20, or 24 bits.

Note: The INPUT MODE selection CANNOT be different for the IN A and IN B input channels.

The INPUT MODE setting procedure is the following:

1. Select the INPUT MODE control page by rotating the encoder wheel and press the OK key or the encoder

wheel (or press the ESC key to cancel and return to the last menu).

2. Select the chosen setting (ANALOG or AES/EBU) by turning the encoder wheel. Press the OK key or the

encoder wheel to enable the setting (or press the ESC key to cancel and return to the last menu).

Figure 30: INPUT MODE setting

In Figure 30 the AES/EBU input mode has been enabled. The LOCK 48 kHz additional message is a status message

indicating that the AES/EBU input mode is active and that the digital audio source provides signals of sampling frequency

of 48 kHz.
