From concerts and festivals to corporate events, theatre productions and outdoor broadcasts, live event crews rely on clear communication to keep everything running smoothly. 

Stage managers, lighting operators, audio engineers, security personnel and event coordinators all need to communicate, but they don’t necessarily need the same equipment. 

The best communication system for live event crews is one designed around their roles, working environment and communication requirements. Depending on the event, the solution may include two-way radios, wired or wireless intercom, or a combination of technologies. 

What communication systems do live event crews use? 

Live event crews typically use two-way radios, production intercom systems and integrated communication networks to coordinate activities across an event. 

Different technologies suit different teams: 

• Two-way radios: Portable, push-to-talk devices commonly used by security, logistics, venue operations and event management teams. 
• Wired intercom: Cable-connected communication systems used by production teams working at fixed positions, such as lighting desks and audio control stations. 
• Wireless intercom: Portable communication systems allowing stage managers, camera operators and technical crews to move around while staying connected. 
• Hybrid intercom: Integrated systems combining wired, wireless and other communication technologies. 

D2N supplies communication solutions for production and theatre, covering live events, concerts, festivals and corporate productions. 

What is the difference between two-way radios and intercom systems? 

The main difference between two-way radios and production intercom systems is how users communicate. Two-way radios typically operate using half-duplex communication, where one person transmits at a time by pressing a push-to-talk button. 

Production intercom systems can support full-duplex communication, allowing team members to speak and listen simultaneously, similar to a telephone conversation. 

For example, security staff managing different entrances may use two-way radios, while a stage manager coordinating lighting, sound and performers may benefit from full-duplex intercom. 

At Byron Bay Bluesfest, D2N supported communication across seven stages using more than 500 radios and 30 talk groups, with selected radio channels integrated into the event’s intercom system. The installation demonstrates how different communication technologies can support both event operations and production coordination. 

When should live event crews use wired or wireless intercom? 

Wired and wireless intercom systems both support production communication, but each has advantages depending on how crews work. 

Wired intercom 

Wired intercom systems connect communication devices using physical cabling, from conventional audio cables to network and fibre connections. They are well suited to fixed production positions where reliable, low-latency communication is required. 

Wireless intercom 

Wireless intercom systems allow production personnel to communicate while moving around a venue or event site. Many systems support multiple communication channels, allowing users to speak with specific individuals or groups. Some wireless intercom systems also support full-duplex, hands-free communication. 

For example, D2N supplied a wireless intercom solution for RISE Pacific, supporting rope access and rigging teams working in demanding environments, including live entertainment venues. Hands-free, full-duplex communication allowed technicians to coordinate while using tools and managing ropes.

Can different event communication systems work together? 

Different event communication systems can be connected through a hybrid intercom solution, provided the equipment and interfaces are compatible. 

For example, a large production may need to connect: 

• Wireless intercom used by stage management and technical crews. 
• Wired intercom panels at production control positions. 
• Two-way radios used by security and event operations. 
• Remote communication links to outside broadcast teams. 

Integration equipment and compatible audio interfaces can allow these systems to exchange communications without requiring every crew member to use identical devices. 

D2N’s hybrid intercom solutions support integration across different manufacturers, technologies and existing venue infrastructure. 

What should you consider when choosing a system? 

Choosing a communication system for a live event starts with understanding how crews need to communicate throughout the production. 

Consider: 

• Crew size: How many people need to communicate? 
• Roles and channels: Which teams need separate or shared conversations? 
• Venue coverage: Will crews work indoors, outdoors or across multiple stages? 
• Mobility: Do users remain at fixed positions or move around? 
• Audio environment: Will headsets need to work in high-noise areas? 
• Existing equipment: Can venue systems or rented equipment be integrated? 
• Reliability: What backup equipment and technical support will be needed? 

Wireless systems also require suitable RF planning, particularly at events where multiple radio and wireless audio technologies operate together.

FAQs 

What communication equipment is used at concerts and music festivals? 

Concerts and music festivals commonly use two-way radios for event operations, wired and wireless intercom for production crews and integrated systems connecting different communication groups. Larger events may require repeaters, RF infrastructure and multiple talk groups to support site-wide coverage. 

What is the difference between half-duplex and full-duplex communication? 

Half-duplex communication allows users to transmit and receive on a shared channel, but generally not simultaneously. Full-duplex communication allows users to speak and listen at the same time. Conventional push-to-talk radios typically use half-duplex, while many professional intercom systems support full-duplex operation. 

Can wireless intercom and two-way radios work together? 

Wireless intercom and two-way radios can be integrated using compatible interfaces and communication equipment. Hybrid intercom systems can connect different technologies, allowing selected radio channels to be accessed through production intercom panels or beltpacks. 

What communication system is best for a large outdoor festival? 

Large outdoor festivals often require a combination of two-way radio networks, production intercom and supporting RF infrastructure. The system should be designed around site coverage, crew numbers, separate communication groups and the operational requirements of each team. 

Can live event communication equipment be rented? 

D2N offers rental options for professional two-way radio, intercom and audio equipment. Options include equipment-only hire and fully managed rental solutions with technical support, depending on event requirements. 

Do live event two-way radios require an ACMA licence? 

Professional two-way radio systems may require an apparatus licence issued by the Australian Communications and Media Authority (ACMA), depending on the frequencies and equipment used. Some compliant radio services operate under class licences without requiring an individual licence. D2N can assist with ACMA frequency licensing for professional radio systems.
