Input and Link Connectors

Analog Inputs
Analog inputs are available on two standard XLR3F latching connectors. The inputs are electronically
balanced and feature Lake Iso-Float circuitry. The impedance is 20 kOhms, and the inputs can accept a
maximum input level of +26 dBu.
Analog Links
Two latching XLR3M connectors are fitted adjacent to the analog input connectors. These are paralleled to
the input connectors to provide an unprocessed analog loop-through to feed additional PLM Series units, or
other equipment.
AES/EBU Inputs
A latching XLR3F connector is provided which accepts an AES/EBU digital audio signal. Input impedance is
110 ohms, please ensure that 110 ohm digital audio cables are used; standard XLR microphone cables are
rarely suitable for reliable digital audio transmission.
AES/EBU is a stereo digital format, and therefore
both PLM inputs are fed via a single connector.
Selection of the analog or digital inputs is made via
the front panel display or control software.
AES/EBU Link
A latching XLR3M connector is fitted adjacent to the AES/EBU input connector. This is paralleled to the
input connector to provide an unprocessed AES/EBU loop-thru to feed further PLMs, or other equipment.
An AES/EBU 110 ohm termination load is enabled by default when the PLM is the last unit connected within
an AES/EBU daisy-chained system. The termination may be disabled, if desired, via the front panel menu
and within the Lake Controller software.

Output Connectors

The PLM is available with a choice of connectors for power outputs: binding posts or Neutrik Speakon.
The PLM is capable of bridge-mode operation,
however currently the system management
software does not support this mode and it is
therefore NOT recommended.
