Two-way radio makes the cut in broadcast production.
Outside broadcast, location filming and studios are challenging environments with many variables in play, from background noise, weather, demanding directors, temperamental talent, and equipment all conspiring against achieving the perfect take or capturing the critical moment.
It’s an industry that understands that time is money and that mistakes cost – whether in missing that crucial news shot or interview, doing a different take or paying for overtime and extra equipment costs.
Little wonder that despite the ubiquity of mobile phones, two-way radio communications cut broadcast production. The ability to communicate between director, producers, actors, lighting engineers, sound engineers, production assistants, grips, and camera operators and the myriad of support personnel within and across groups, clearly and instantly, can often make the difference between chaos and success.
One of the advantages of two-way radio is that it allows you to set up a channel specific to each department or group. Team members can instantly exchange instructions and responses while allowing priority and emergency calls to break-in and additional open channels for more extended conversations.
A RANGE TO SUIT EVERY BROADCAST APPLICATION
With the financial risks and pressures on the broadcast and film industry, it’s tempting to cut corners and shave costs. For example, multi-packs of consumer PMR446 walkie-talkies from a supermarket, catalogue store or even toy shop bought for less than half the price of a decent microphone. While they might work, they are not designed to survive the rough and tumble of broadcast activities, usage in all weather conditions (and with gloved hands) or last a long day’s work without needing to be charged or replace batteries.
A license-free or licensed two-way radio is a critical piece of equipment. Giving production management the ability to coordinate operations being carried out by individuals and teams, often working out of the sight colleagues reliably and clearly at the push of a button to optimise efficiency and safety. Especially important when circumstances change or in the event of an incident requiring assistance, so it pays to invest in the right kit for the job.
Typical applications include:
- Safety of lone and out of sight units and crew
- Supervision of cast and extras

Exceptional audio quality even in noisy environments
KENWOOD radiocommunication devices benefit from JVCKENWOOD Group’s 60-years of experience in producing consumer audio and visual equipment (Trio, JVC and KENWOOD), renowned for exceptional sound quality.
This transfer of knowledge and experience has led to the development of several novel and innovative solutions which overcome the problem of cancelling ambient noise while improving the audio clarity of the transmitted voice in any operating environment.
|Ultimate noise cancellation:||
NX-5000 Series hand-portable radios achieve optimum noise cancellation using two integrated microphones. The primary microphone is situated closer to the desired source (front of the radio), while a second microphone in the radio's rear receives the ambient noise. In a noisy environment, both microphones receive noise at a similar level. However, the primary microphone receives the user's voice more strongly. The processor in the radio subtracts one noise source from the other so that most of the ambient noise is cancelled out, which effectively enhances the quality of the transmitted audio of the user's voice.
|Active Noise Reduction:||
Both NX-5000 and NX-3000 Series radios feature Active Noise Reduction (ANR). ANR serves to cancel the noise component of the collected audio to improve the transmitted audio quality. Noise cancellation functions can be 'Custom' configured to adjust the vocoder, DSP, filters, specific noises etc., to suit the operating environment.
|Selectable Audio profiles:||
The received audio will sound different depending on the usage environment of the radio, characteristics of the device (such as the microphone to be combined with the radio and external devices), and the tone of voice and manner of speaking of the speaker. The received audio will also sound different depending on the output method, such as using the radio speaker or earphone to hear the received audio. KENWOOD radios feature six customisable audio profiles which can be configured for specific scenarios and selected by the user to suit the operating environment.
ADVANCED HEALTH & SAFETY AND LONE WORKER PROTECTION
All NEXEDGE NXDN and DMR digital two-way radio devices feature an Emergency Key. Emergency Call features as standard, while more advanced models additionally offer built-in or optional GPS modules, Lone Worker, Motion Detection, and compatibility with Location services, which can be programmed to deliver automated proximity triggered prompts. For example, when the crew enter a hazardous area requiring special safety clothing or checking a safety status with a member of the production management team, they are essential in a robust health and safety policy.
These advanced safety features offer an added layer of protection in support of emergency and first aid protocols with the ability to automatically send alerts and alarms to the production control unit and/or other radio users, for example:
The Priority Call feature ensures the availability of a radio channel in the event of an emergency and allows a control centre to interrupt all existing calls on a channel.
An alarm is triggered along with the sender's user ID and when the Emergency Key button is pressed. GPS equipped radios can additionally send the location (GPS coordinates) of the user.
An alarm is triggered along with the sender's user ID if a user does not respond to a status prompt within a specified time.
An alarm is triggered along with the user ID of the sender if the radio is tilted beyond a pre-determined angle indicating that the user may have fallen or become incapacitated. Other programmable features include:
- Stationary Detection: Emergency mode is triggered along with the user ID of the sender when the radio remains in a stationary position for a period exceeding a pre-set time, indicating that the user is unable to operate the transceiver, or it’s has been lost, mislaid etc. GPS equipped radios can additionally send the location (GPS coordinates) of the user to a control centre using software such as KAS-10 and KAS-20 AVL and Dispatch suites.
- Motion Detection: Emergency mode is triggered along with the user ID of the sender when the radio is vigorously shaken or swung for a period exceeding a pre-set time, indicating that the user is running to or from an incident. GPS equipped radios can additionally send the location (GPS coordinates) of the user to a control centre using software such as KAS-10 and KAS-20 AVL and Dispatch suites.
NEXEDGE NXDN and DMR radios equipped with GPS can additionally be programmed to send location information to the control centre using software such as KAS-10 or KAS-20 AVL and Dispatch suites so that the user at risk can be located quickly and response times reduced.
|Asset Tracking and Monitoring:||
With Trackuracy, KENWOOD DMR and NEXEDGE NXDN systems can be equipped with low-energy, real-time asset monitoring and tracking across single and multiple sites, indoors and out. Alerts, alarms delivered as audible tones, voice or data messages can be programmed to trigger automatically should the user stray off course or enter restricted areas.
Remote Monitor allows control centre staff to listen in to a radio through its microphone in situations where an alarm is activated, and the radio user is unable to respond. This provides Health, Safety and Security management with the intelligence to assess a situation in real-time and to quickly initiate an appropriate response.
|Intrinsically Safe Radios:||
NEXEDGE NXDN ATEX/IECEx certified radios provide the solution for crew operating in explosive atmospheres or situations where hazardous airborne particles are present.
