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.
