GREEN-GO DIGITAL INTERCOM SYSTEM - Analogue interfaces

These interfaces are rack-mounting or slimline, desk-top intercom stations with analogue ports for linking Green-Go intercom groups to external analogue intercom systems or other audio equipment. 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.

GGO-InterfaceX - 2 and 4-wire

The 1U rack-mounting GGO-InterfaceX is a useful combination of two channels of 4-wire to 4-wire together with a single channel of 2-wire to 4-wire.

The 4-wire interface offers two channels of analogue in and out. Uses include linking to an external matrix intercom, injecting program audio on to the Green-GO network and sending analogue audio to an external PA system or show relay.

The 2-wire interface offers a single channel of robust interfacing to popular partyline systems including Clear-Com, RTS-TW and Tecpro.

Two GPIO connections are also included, providing opening or closing contacts to trigger selected functions. The GGO-Interface is powered by Power over Ethernet or optional 12V power supply. Dimensions: 1U x 150mm deep. Weight: 2.3kg.

GGO-Q4WR 4-Wire Interface

The Quad 4-Wire interface provides four pairs of line level analogue In and Out ports on 3-pin XLR connectors. Suitable for importing programme audio and show relay and for broadcasting out to PA systems. Other uses include interfacing with camera CCUs and third party 4-wire intercom systems.

Main points:

  • Provides 4 pairs of analogue Input and Output ports, individually programmable
  • Separate audio signals can be injected into and extracted from the Green-GO network
  • Link to any 4-wire device including third party 4-wire intercom systems
  • Input programme audio and show relay
  • Feed audio to the PA, to show relay loudspeaker systems and to presenter’s IEMs
  • Double the sample rate to suit audio sources with extended HF content
  • Includes 4 GPIO general purpose In/Outs providing opening/closing contacts to trigger external devices
  • TFT colour display offers easy menu navigation and setup
  • The rotary knob acts as both a volume control and an encoder for programming
  • Compact 1U format

For optimum performance, each of the four balanced line inputs of the Q4WR interface offers level control, gain reduction and noise gating. For gain matching, level control is also available on each output.

The standard Green-GO sample rate of 16kHz provides an audio HF response of 7kHz which works well for speech reproduction. If an audio signal has significant HF content, like cymbals, the sample rate of individual ports can be doubled, resulting in an HF response of 14kHz, similar to broadcast quality.

Each pair of 4-wire ports can be individually programmed to operate in standard ‘Line In/Out’ mode or in ‘User’ mode which allows programme audio to be added to the audio output. The programme audio can be set to dim or mute when the show caller makes an announcement on that channel. This is eminently suitable for feeding presenter’s IEMs or for transmitting show relay to dressing rooms or the green room.

In addition to the 4-Wire ports, there are four GPIO general purpose inputs/outputs which each offer a pair of opening and closing contacts on a 9-pin D-Sub connector to trigger external devices or internal green-GO functions.

The large TFT colour display allows easy menu navigation during setup. The encoder (volume) knob facilitates scrolling through and selecting menu options.

Specifications:
Dimensions: 485 x 160 x 45 mm
Weight: 2.45 Kg
Power: Power over Ethernet (IEEE 802.3af)
Power consumption < 5 Watts
Optional external 12V DC Power Supply

GGO-SI2W Slim Audio Interface 2W

The Green-GO GGO-SI2W 2-Wire Audio Interface is a compact, single channel interface for integrating analogue party line systems with Green-GO digital intercom. ‘Call’ signalling will pass between both systems together with ‘Announcements’ and ‘Program Audio’.

Main points:

  • 'Auto Null' prevents echoes being generated
  • Clear-Com and RTS-TW templates
  • Tecpro template coming soon
  • Adjustable noise gate with 'Threshold' and 'Hold' controls
  • Passes DC and AC 'Call' alert signals between both comms systems
  • 1 x 3-pin XLRF port for 2-Wire connection
  • 1 x etherCON RJ45 port for network connection
  • Single Green-GO group assignable as send/receive for analogue comms
  • Lightweight, rugged ABS casing
  • Powered by PoE (802.3af-2003 standard)

Ideal for integrating a Green-GO DECT wireless system with existing Tecpro, Clear-Com, RTS-TW and similar analogue comms. The GGO-SI2W interface will link to a single channel of analogue intercom. If linking to two or more channels is necessary, additional GGO-SI2W interfaces will be required.

When Linking to RTS-TW, due to the pin configuration, only channel B is connected. An adapter cable can be easily made to swap from channel B to channel A - see cable connection info at the end of this product description.

The GGO-SI2W integrates robustly with analogue party line comms, providing a clear, echo-free, low noise, low latency link. For theatre applications where there is little sound reinforcement, whispered instructions will be heard clearly by the operators. If hum and hiss from the analogue partyline is noticeable, a noise gate can be activated to help minimise system noise.

The compact GGO-SI2W can be plugged into any convenient 3-pin XLR access point on the analogue intercom ring. It will draw no current from the comms line as it is powered by PoE (Power over Ethernet) supplied from a suitable network switch. Four green buttons on the front panel provide access to the menu where the device can be set up for best audio performance. Information is displayed on the full colour Oled screen.

Note: poorly installed audio cabling can result in high levels of hum and noise being present on analogue party line comms. This may make it difficult to null the system correctly.

Dimensions: 120 x 95 x 40 mm
Weight: 240g
Power: Power over Ethernet (IEEE 802.3af)

GGO-SI4W Slim Audio Interface 4-Wire

The Green-GO GGO-SI4W 4-Wire Audio Interface is a compact, single channel audio interface for importing and exporting analogue audio to and from the Green-GO digital network. It can act as a general purpose line in/out device suitable for show relay and announcements or for linking to an external matrix intercom channel. Alternatively, in ‘User’ mode, it offers access to 32 intercom channels and to program audio.

Main points:

  • Switchable 'Line In/Out' and 'User' modes
  • 1 x 3-pin XLRF Line In port, balanced
  • 1 x 3-pin XLRM Line Out port, balanced
  • 1 x etherCON RJ45 port
  • Adjustable input and output levels
  • Switchable limiter with max input level adjustment
  • Adjustable noise gate on input
  • 'Programme' audio dims/mutes when talkback is active – suitable for IFB
  • 'Standard' sample rate 16kHz, 'Enhanced' mode 32kHz
  • 32 available intercom channels
  • Lightweight, rugged ABS casing
  • Powered by PoE (802.3af-2003 standard)

Four buttons on the front panel provide access to the menu where the device can be set up for best audio performance. Information is displayed on the full colour Oled screen.

The GGO-SI4W interface has two modes of operation. For normal interfacing duties, it should be set to ‘Line In/Out’ mode. This is suitable for inputting programme audio material or show relay on to the Green-GO network, sending analogue feeds to external audio systems or for linking to an external matrix intercom.

‘User’ mode provides additional options suitable for sending IFB audio to a wireless transmitter for presenters. This includes selectable sources for Program Audio which can be adjusted in level and set to dim or mute when the Director or Show Caller talks to the presenters. This mode is also suitable for sending show relay to green rooms and dressing rooms.

The default sampling rate of the Green-GO system is 16kHz, giving an upper audio limit of 7kHz. This is eminently suitable for speech, while minimising data use. If there is significant high frequency content in an audio source (for example music) being fed on to the Green-GO network, the sample rate of the GGO-SI4W’s A-D convertor can be doubled to 32kHz, increasing the upper audio limit to 14kHz.

To link to remote sites, a single GGO-SI4W interface can be used to connect over the internet to a remote Green-GO intercom situated anywhere in the world. To avoid using a local bridge unit, bridging functions can be carried out at the remote Green-GO site and the SI4W set to ‘Remote’ mode. This would make it possible to link another manufacturer’s intercom to a remote Green-GO system using a single, dedicated group.

Dimensions: 120 x 95 x 40 mm
Weight: 240g
Power: Power over Ethernet (IEEE 802.3af)
