ARJ12P - Hardware Manual1

Junction box for connecting peripheral devices to a standard line input

The ARJ12P is a junction box for connecting peripheral devices to a standard line input. It enables signal transfer

over long distances over a twisted cable. With its ability to transmit signals over long distances through a twisted

cable, the ARJ12P offers reliable and high-quality performance for various applications. The junction box can be

used in both ways, either audio signal can be sent thru or received from the RJ45 bus connector.

Because the ARJ12P is a passive junction box, the maximum cable run length is dependent on the following

factors: connected input, cable type (shielded or unshielded, CAT rating, etc.), and installation location (next to

power cabling, dimmers, etc.). The unbreakable plastic housing allows easy mounting on Mini DIN rails.

Connections

RJ45 bus connector

The RJ45 bus connection is used to carry a balanced stereo audio signal and 24V power to the peripheral.

DC input

The DC input is used to supply the peripheral input with the required voltage via an external power supply

connection. Please check the specications of the connected unit for power requirements and pay attention to

the polarity markings.

3-pin Euro terminal block output connections

3-pin Euro block connectors are used for the connection of stereo audio signals to a balanced input (e.g. connected

pre-amplier). Please check the input section of the connected device whether it is capable of handling the output

level of the connected peripheral (e.g. +12 dBV).

Ground lift dip switches

Ground lift dip switches provide the option to eliminate unwanted hum and buzz by interrupting the ground,

this prevents current from owing through the cable shielding resulting in a clean audio signal.
