PLM Series Operation Manual rev 1.2.3
4.2.1 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.
AES3 Inputs
A latching XLR3F connector is provided which accepts an AES3 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.
AES3 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.
AES3 Link
A latching XLR3M connector is fitted adjacent to the AES3 input connector. This is paralleled to the input
connector to provide an unprocessed AES3 loop-thru to feed further PLMs, or other equipment. An AES3
110 ohm termination load is enabled by default when the PLM is the last unit connected within an AES3
daisy-chained system. The termination may be disabled, if desired, via the front panel menu and within the
Lake Controller software.
4.2.2 Output Connectors
The PLM is available with a choice of connectors for power outputs: binding posts or Neutrik speakON ® .
Both connection methods allow for Bridge Mode operation, which is activated from the Lake Controller
software. Please refer to the Lake Controller Operation Manual and section 8.1.1 of this Operation Manual
for further information on Bridge Mode.
