Input Connectors
1
Analog Inputs – Four analog inputs are available on standard XLR-3F connectors, electronically balanced and
featuring Lake Iso-Float circuitry. Impedance is 20 kohms; maximum input level is +26 dBu.
2
AES3 Inputs – Two latching XLR-3F connectors accept four channels of AES3 digital audio. Input impedance
is 110 ohms; ensure that 110 ohm digital audio cables are used.
Output Connectors
The PLM20K44 and PLM12K44 are Your device will be equipped with one of the two output connector options.
Both options allow for Bridge Mode operation, which is activated in the Lake Controller software. Please refer
to the Lake Controller Operation Manual for more information. The PLM5K44 is equipped with both binding posts
and speakON connectors, and does not support Bridge Mode operation.
3
Binding Posts – Power outputs are available on four separate pairs of fully enclosed binding posts.
4
speakON connectors – Power outputs are available simultaneously on a single 8-pole connector (PLM20K44
and PLM12K44 only) and on two 4-pole connectors. The four-pole connectors carry outputs for channels 1&2
and 3&4 respectively. For PLM5K44, connector 1 carries output channels 1 and 2, connector 2 carries channel 2,
connector 3 carries channel 3and 4, and connector 4 carries channel 4.

Ethernet and Power Connectors
5
Primary Network Connector – The primary Neutrik RJ45 etherCON® connection provides integration into
an Ethernet control network which may include other Lake Processors and the Lake Controller software. Network
connection permits full control of all functions along with real-time metering from a remote position. This device
supports the Dante audio networking protocol for multichannel, high-definition digital audio over the same Ethernet
connection. It also supports AES67 audio flows.
Use the primary connector when using a star network topology, consisting of individual Cat-5e connections
between the devices and an Ethernet switch. Alternatively, this connection can be used to daisy chain directly to
another Lake Processor. The daisy chain topology should not be used with Dante.
Note: Do not create a closed loop when g ifnoc uring multiple devices in an Ethernet network; this will
cause a network malfunction.
6
Secondary Network Connector – The secondary network connector can be used to daisy-chain multiple
PLM+ Series devices. Alternatively, a Dante dual-network topology can be created by connecting all secondary
network connectors to a separate Ethernet switch, ensuring full redundancy in the event of a network component
failure. 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).
7
Mains Power Connector – AC mains input for the PLM20K44 and PLM12K44 is via a Neutrik powerCON
connector, rated at 32A. Connector mates with supplied AC mains cable. PLM5K44 uses a standard IEC locking
connector. See previous section on Operating Voltage for more information.
