ed via Lake Controller. See the Lake Controller Operation Manual for further details.
Secondary Connector – The secondary network connector can be used to create a Dante dual–network
topology by connecting all secondary network connectors to a separate Ethernet switch, ensuring full
redundancy in the event of a network component failure. Alternatively, the secondary network connector can be
used to daisy–chain multiple Lake devices (LM, PLM, PLM+ or D Series), if Dual Redundancy is Disabled from
the Lake Controller. When the device is in Dual Redundancy , it is possible to connect a Lake Controller to the
Secondary Connector as long as the IP address on the computer is on the 172.31.x.x subnet.
NOTE: When connecting multiple devices to an Ethernet network, care must be taken NOT to create a
closed loop which causes network malfunction.

11. Operation and performance
11.1. Operation precautions
Make sure that the Standby button on the unit’s f ront panel is either unlit (OFF), or red (STANDBY), before making
any input or output connections. Ensure the AC voltage is within the range printed on the label adjacent to the AC
mains connector. Ensure no input signal is present when powering on the unit to reduce the risk of any inadvertent
bursts of high level audio.
11.2. Power output performance
The standard form factor D Series units (D200, D120 and D80) uses Lab.gruppen’s patented Class TD
purity of Class A/B designs. The slimline D Series units (D40, D20 and D10) uses a newly developed Class D:
perfectly under all load conditions and the output maintains it
with very low nominal impedances. Reliability is very high, and there is no interference with nearby RF equipment.
If the device has dual redundancy enabled, any AES67 audio must be on the primary network (i.e. AES67
cannot be transmitted or received on the secondary connector).
