The SI4WR 4-Wire Interface

SI4WR Front View

The SI4WR 4-Wire Interface X is a single port 4-wire device, used for integrating line level audio signals, in and out of the system. Featuring a full-color OLED display that shows information about channels, cue signals; configurable by the four buttons on the front of the device with access to many of the same functions and features as most other Green-GO devices.

Connectivity to 4-wire systems is achieved via 1x XLR3F and 1x XLR3M. Powered via PoE through a network cable connected to the devices Ethercon port.

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?

The Green-GO SI4WR 4-wire interface comes with the following package contents:

  • 1 x Green-GO SI4WR 4-wire interface
  • 1 x Printed quickstart guide
Optional Green-GO accessories
  • Green-GO PoE network switches

The user interface

SI4WR User Interface

The user interface of the SI4WR slim 4-wire interface is simple and compact. On the top, the user that is currently linked to the interface is shown.

The currently enabled channel(s) and the signal level coming from the connected XLR3 line input is displayed right below the username.

On the bottom of the screen, the currently receiving channel(s) is displayed together with the received signal level going to the connected XLR line output.

Tip: Please check out our 4-Wire Systems Guide to find out more on how to configure your 4-wire system or analog audio integration.

The setup menu

The setup menu allows local access to almost all user and device configuration properties. All changes in the setup menu are done and stored locally on the device but can be easily synced back into the configuration file using the Green-GO Control software. These settings are also persistent on the device unless overwritten.

One Channel Interfaces Setup Menu

The setup menu is accessed by sequentially pressing both left-hand buttons (Button 1+Button 2).

One Channel Interfaces Setup Menu

Once inside the setup menu, the left-hand buttons will change function:

The Button 1 (top-left) confirms a selection or value while the Button 2 (bottom-left) can be used to either exit the current (sub-) menu or cancel a value selection.

The right-hand buttons (Button 3 and Button 4) are used to move a selection or change a selected value.

A (sub-) menu can be exited either the the menu entry Exit or Cancel, and alternatively with the Button 2 (bottom-left).

Access to the setup menu can be restricted by configuring the security options of a configuration file or user with the help of the Green-GO Control software. In restrictive security configurations, the user may be asked to enter the Tech Pincode before access is given.

Tip: More information on security options can be found here.
