The Q4WR Quad 4-Wire Interface

Q4WR Front View

The Q4WR 4-Wire Interface is a quad port 4-Wire device, used for integrating line level audio signals, in and out of the system. Featuring a full-color TFT or LCD display that shows information about channels, cue signals; configurable by a multifunction encoder, with access to many of the same functions and features as most other Green-GO devices.

Connectivity to 4-wire systems is achieved via 4x XLR3F and 4x XLR3M. Powered via PoE through the network cable connected to the devices Ethercon port or 12V DC connector (power supply not included).

The term 4-wire refers to two pairs of (balanced) wires, providing independent, bidirectional audio lines. They can act as a general-purpose line in/out device suitable for show relay and announcements or for linking to an external intercom channel.

What's in the box?

1 12V DC barrel connector
The 12V DC barrel connector serves as the secondary power input and can be used with an optional power supply.
1 2-Port 10/100 Mbps Neutrik EtherCON Switch
A 2-port 10/100 Mbps network switch with Neutrik EtherCON connectors. The first network port LAN 1 accepts PoE (IEEE 802.3af) and is the primary power input for the device.
4 D-Sub 9 GPIO connector
Two GPIO D-Sub9 connector each serve two in- and outputs for external control interfacing. Each GPIO port is directly linked to one 4-wire Green-GO Engine port.
4 - 4-Wire Ports
A Neutrik XLR3-Female Line-Input and A Neutrik XLR3-Male Line-Output for each port . The balanced XLR3 male line-input connector allows injecting analog audio signals into the Green-GO system. The balanced XLR3 female line-output connector allows extracting analog audio signals from the Green-GO system. Audio signals from and to the port are processed dependant on the 4 wire port mode.

The user interface

The user interface features one color TFT display and one multifunction Encoder.
