About this product

GREEN-GO DIGITAL INTERCOM SYSTEM - Desktop and fixed stations

These are desk-top, rack-mounting and wall-mounting intercom stations. They communicate over the network with other Green-Go digital intercom stations. Each station is connected to a network switch using standard Ethernet cabling. They can be powered over the network if the switch provides power over Ethernet; an accessory power supply can be used for desktop and rack-mounting types.

Multi-channel Desktop Stations

Multi-channel desktop stations have a compact footprint and are available in 8, 16, 24 and 32 channel versions. They provide a clear overview of many channels and offer a simple interface to listen and talk to selected channels. This makes the system suitable for complex live event and broadcast applications where several intercom channels need to be simultaneously monitored while conversing with one or more selected channels. Each channel identification is displayed on an LCD strip. The audio level of each circuit can be adjusted for best intelligibility.
Full duplex communication is by headset or the in-built loudspeaker and optional gooseneck microphone. Intercom channels are presented in banks of four and each channel is controlled by two rows of four switches. The upper row enables conversations with other stations on the selected intercom channel. These switches offer latching and non-latching modes, depending on the duration for which they are pressed. Each microphone switch illuminates green, orange or red (blinking) to indicate talk to the channel, talkback from the channel, or 'Call' signal received. The lower row of switches operate in conjunction with the three 'Soft' keys and four 'Mode Select' keys in the Control Section to offer three functions; 'Listen' and 'Remote Mic Kill', 'Call' (to a group or individual) and 'Cue' modes. For improved listening, the 'Isolate' function will mute all intercom circuits that are not in 'Talk' mode, so unnecessary distractions are removed until the conversation is finished.
Multi-channel desktop stations may be powered from PoE (Power over Ethernet) or an external 12V DC power supply. The rear panel offers two Ethernet ports with built-in Ethernet switch. Port 2 can be used for power via PoE if no external 12V supply is available. This leaves Port 1 available for a laptop which may be connected for system set-up.
Line-in and line-out facilities are presented on 3-pin XLR connectors. They allow analogue audio to be injected into and extracted from the intercom system. A set of General Purpose Input Output (GPIO) connections are available on a D-sub 9-pin connector, providing opening and closing contacts to provide external control interfacing.

Rack-mounting Station

The 12-channel rackmount station has similar features to the desktop stations, but is designed to fit in 2U of a 19 inch rack. The front panel can be angled outwards to make operation easier.

Wallmount Stations

Two wall-mounting outstations, based on the beltpack, are available. The external Ethernet connection is relocated inside the case and GPIO (2x in and 2x out) connections are available internally using screw terminals. The size of the LCD display is larger than that of the beltpack. Two versions are available; a speaker and microphone combination or a headset only alternative. A non-audio version is also available for information/cue-light duties.


The 4-pin, male, XLR, headset connectors are compatible with headsets with an impedance greater than 32 ohms and fitted with mating connectors such as those from Tecpro, Beyer and many other brands. If the microphone type is an electret, a switchable bias voltage is available.

Gooseneck microphones

Where the intercom station has a 3-pin female XLR connector for a microphone, Canford CxxxXB24 types are suitable.
