Lab.gruppen PLM Series PLM 10000Q Quick Start

18 PLM Series Quick Start and Field Reference Guide
7 CONTROLS AND CONNECTIONS
Note that the AES/EBU digital audio format is two-
channel, and thus 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.
Always use 110 ohm digital audio cables.
NEVER CONNECT A DIGITAL AUDIO
SOURCE TO AN ANALOG INPUT, OR VICE-
VERSA. Always use the correct type of cable and
connectors for the two different types of signals. If
you are unfamiliar with digital audio transmission
techniques, seek guidance from authoritative refer-
ences or qualified personnel before attempting to
interconnect equipment in the digital domain. See
section 12.5 of the PLM Series Operation Manual
for further information.
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 AES/EBU loop-thru
to feed further PLMs, or other equipment. An AES/
EBU 110 ohm termination load can be enabled, via
the front panel menu, when the PLM is the last
unit connected within an AES/EBU daisy-chained
system.
7.2.2 Power output connectors
The PLM is available with a choice of power output
connectors: Binding posts or Neutrik Speakon.
The PLM is capable of bridge-mode operation;

7.2.1. Input connectors and Links
See section 10 of the PLM Series Opera-
tion Manual for full details of connector
pinouts, etc.
Analog inputs
Analog inputs are available on two standard XLR3F
latching connectors. The inputs are electronically-
balanced using Dolby’s patented Iso-Float circuitry.
The impedance is 20 kOhms, and the inputs can
accept a maximum input level of +26 dBu.
Grounding
Analog inputs feature the Iso-Float ground
isolation system as standard. Iso-Float may
be disabled via the supplied Dolby Lake Controller
PLM Series Edition software, or via the PLM’s menu
system. Use correctly-shielded balanced audio input
connections to minimise hum and interference. For
more information on grounding, see section 5.6.
Analog links
Two latching XLR3M connectors are fitted adjacent
to the analog input connectors. These are paralleled
to the input connectors to provide an 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.
