Unlike other digital intercom designs, Green-GO does not employ an expensive central matrix. All interconnection routing data, system set-up and user preferences are stored locally within each user station including beltpacks, which eliminates the possibility of a catastrophic central failure.
Green-GO does not require a dedicated Ethernet network. It will operate on any 100Mbit network without interfering with other data protocols coexisting on the system, including Dante. User stations are powered by Power over Ethernet (PoE). If this is not available locally, any good quality PoE switch may be used including Green-Go's own 5-port switch.
Canford product manager Mike Reay is upbeat about the new partnership. "Green-GO digital intercom is stirring up a great deal of interest and is now being specified by consultants. It is an excellent fit with our own widely used analogue partyline system, allowing us to address more complex projects which exceed the capabilities of traditional analogue designs. The system brings the benefits of digital control, giving designers the freedom to create up to 250 intercom channels with a maximum of 3,000 users."
Audio quality is high and latency is only 12ms. Useful features include channel ident, display of simple text messages and cue light facilities. System set-up is carried out via a laptop using free software for PC or Mac which can be downloaded from the Green-GO website.
The current range includes beltpacks, wall stations, multi-channel desks (8, 16, 24 and 32 channels) and interfaces for integrating with analogue two and four-wire intercom systems. The recently introduced bridge interface enables venues in different locations to link their Green-GO comms together via the internet, while retaining full system functionality.
A basic intercom system can be created with just two beltpacks and, if Power over Ethernet is not available, a PoE switch. It can then be expanded as technical requirements and budget dictate. With no heavy investment required for a central matrix, Green-GO offers a uniquely cost effective way to build a digital intercom system, making the latest technology available to many who, up to this point, found it hard to justify the expense.
