NLC5.1ST User Manual
passive output are present when this option is installed. Supported formats include SMPTE 259M,
SMPTE 292M, and SMPTE 424M as well as ITU-R BT.656 and ITU-R BT.601. See the HD/SDI section
of this manual for more details.
The AES-3id-1995/SMPTE 276M standard dictates a 75 unbalanced connection and requires proper
termination. The termination should occur at the destination of the signal (that is, on the inputs to
NLC5.1ST). If the output BNC connectors are not feeding additional equipment, terminate each of
these with a standard 75 terminator. Like other inputs, AES-11 external sync and HD/SDI input signals
should also be terminated if the outputs are not feeding additional equipment. Proper termination of
these signals will prevent reflections that may cause audio errors or clock problems.
GPIO
– A Female DB-9 connection that allows NLC5.1ST to be monitored or controlled externally.
Opto-isolated inputs will be triggered by a voltage of 5VDC.

Output 1: Relay 1 is Normally Open. Upon an alarm condition, this relay will close. When the failure is
remedied, the relay will open.
Output 2: Relay 2 is Normally Open. Upon a fault condition, the relay will close. When the failure is
remedied, the relay will open.
Input 1: Momentary voltage detected on this port will cause NLC5.1ST to toggle the 5.1 surround signal
flow OUTPUT MODE between IN-LINE and BYPASS. When in BYPASS mode, no loudness
corrections are performed.
Input 2: Momentary voltage detected on this port will cause NLC5.1ST to toggle the 2.0 auxiliary stereo
signal flow OUTPUT MODE between IN-LINE and BYPASS. When in BYPASS mode, no loudness
corrections are performed.
Input 3: Momentary voltage detected on this port will cause NLC5.1ST load a specific loudness control
parameter preset that is defined under the I/O menu.
Input 4: Momentary voltage detected on this port will cause NLC5.1ST load a specific loudness control
parameter preset that is defined under the I/O menu.
NETWORK
- Used for logging or to update the NLC5.1ST firmware. To connect directly to a PC without
use of a network switch or hub, a crossover cable is required. Firmware updating is accomplished via
UDP Port 44600. Please refer to the NLC5.1ST Remote Dashboard section of this manual for more
details on logging, or the Firmware Update section of this manual for the update procedure.
