The Green-GO MCR12 is a 32 channel digital comms panel that comes with 12 quick access channels. Green-GO is an IP based digital comms system capable of supporting up to 3000 users with 250 groups.
The MCR 12 has a compact footprint . It provides 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.
The desktop station 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.
