Hollyland Geo Central Station

Hollyland Geo Central Station is the rack hub for a production communication system, giving the crew one place to manage power, connection, and talkback. Based on the source images, it supports AC input, DC input, PoE output, and LEMO audio connectivity, which makes it a practical fit for control rooms, live event racks, and mobile production builds.

The power side is where this unit starts to make sense in the field. It accepts 85V–264V AC input or 46V–54V DC input, and it can deliver 120W total PoE output with up to 60W per port. For a system tech, that means fewer separate power runs and a cleaner rack when connected devices need power from the central station.

• 120W total PoE output with up to 60W available per port
• AC and DC input support for flexible power setups
• LEMO audio connectivity for voice-focused communication workflows
• Rack-style form factor for control rooms, live events, and mobile production systems

Why It Helps

Comms are one of those things nobody wants to think about once the show is live. They just need to work. The Geo Central Station gives the crew a dedicated base station with power handling, PoE support, and voice communication built into the same rack-style unit. That helps keep the setup cleaner, especially when the system is used for long events or shared between production spaces.

The LEMO audio specs are clearly aimed at speech, not music playback. The 150Hz–7kHz frequency response, 20dB noise cancellation depth, and 67dB signal-to-noise ratio all point toward clear crew communication during live operation.
