6.4 Audio and network cabling
6.4.1 Connection panels
The amplified controller’s back side features four connection panels (Figure 8): ANALOG for analog audio distribution,
AES/EBU for digital audio distribution, SPEAKER output, and L-NET for remote control with LA NETWORK
MANAGER Software.

6.4.2 Analog audio cabling
The analog XLR connectors on the LA8 are wired according to IEC 268:
Pin 1= shield; Pin 2 = hot point (signal with normal polarity); Pin 3= cold point (signal with inverse polarity).
Two 3-point female XLR input connectors (IN A and IN B) are provided for the amplifier to receive two analog signals.
The headroom of the input circuits is high enough to accept the maximum output level from virtually any line level signal
source (up to 22 dBu).
In order to set a daisy-chain layout, two 3-point male XLR connectors (LINK A and LINK B) can be used to feed the
input signals to the next unit in the signal chain (see Figure 9) .Both LINK connectors are passively wired in parallel on
channel A and B (see Figure 10). The input impedance is high enough (22 kΩ, balanced) to allow multiple parallel input
connections.
