The NLX-18 is a 3G/HD/SD-SDI audio multiplexer designed to simultaneously embed 2 AES/EBU signals as well as 2 stereo analogue audio signals into an SDI.
The NLX-18 accepts a 3G/HD/SD-SDI signal on an BNC connector a processed output of that signal with the audio embedded is also available on a BNC connector. A recessed DIP switch allows the user to assign the AES/EBU audio inputs and the analogue audio inputs to any of the 4 groups to be embedded. The 2 unbalanced AES/EBU signals are on 75 Ohm BNC connectors while the balanced stereo analogue audio inputs are on 5 pin pluggable terminal block connectors.
A dual colour LED will illuminate green indicating the NLX-18 is locked to a valid SDI input signal or the LED will be illuminated red showing the unit is powered but not locked to a valid input signal.
The NLX-18 has a rugged solid steel powder coated chassis and is powered by an external AC adapter with a locking DC connector supplied with the module.
