•MIC OUT: 4-pin mini-Phoenix connector, divided into GND, OUT-, and OUT+ terminal connectors.

An example of this cable is to strip the terminal ends of a 3.5mm mini-jack and insert them into their respective locations on the Mic Out port. This signal can be fed as a Line Level In to either an amplifier or an AMX VOL card.

Either a balanced (+, -, and GND) or unbalanced (+ and GND) audio signal can be connected to this output.

•Video In BNCs: Feeds either Composite/S-Video Luma or S-Video Chroma signals into the NXA-AVB/ETHERNET. This feed is then redirected out to a Modero panel through the front Audio/Video CAT5 port.

•ETHERNET: RJ-45 connector routes data to the G4 touch panel through the front Ethernet port. These connections use a standard CAT5 Ethernet cable to provide communication between the target touch panel, breakout box, and NetLinx Master.

• PWR	2-pin mini-Phoenix connector that connects to a PSN power supply. This port
	can be used to provide power to a Modero panel by sending it through the
	NXA-AVB/ETHERNET (rear power connector through to the front power
	connector).

Wiring the NXA-AVB/ETHERNET for Unbalanced Audio

Most domestic audio equipment has unbalanced audio inputs and outputs. This means that the audio output (left, right, or mono) appears on a single wire, and is referenced to "0 V" or "Ground". Typical connectors used are RCA "phono" connectors, DIN plugs/sockets, and 0.25" (6.3mm) or 3.5mm jack plugs/sockets.

Unbalanced audio is adequate for most domestic environments and for line-level signals in a typical broadcast studio. Problems may occur if the signals are carried over long distances, especially if the source and destination have separate main supplies. Use the following wiring drawing (FIG. 8) to configure an unbalanced audio connection.

FIG. 8 Wiring the rear AUDIO IN and MIC OUT for use with Unbalanced Audio

When using unbalanced audio for the AUDIO IN connector (FIG. 8), the "-" and the "GND" terminals should be connected together and then connected to the GND of the unbalance audio signal. When connecting to an unbalanced audio input from the MIC OUT connector (FIG. 8), wire the "+" terminal to the signal input, and the "GND" terminal to the signal ground.
