Kenya’s NRG Radio goes on-air and streams with Lawo consoles

A great deal of thought has been invested in the studios, control rooms, technology and concept behind Nairobi’s new local radio and audio/video streaming channel, Kenya’s NRG (Energy) Radio. With high-profile staff recruitment and test transmissions made over the past three months, NRG Radio has brought a new wave of radio technology to its premises with its Lawo crystal and sapphire radio mixing consoles, and R3LAY virtual radio mixers.

Launched with the claim: “we’re gonna change the way you listen to music”; NRG Radio is changing the way its programming is delivered. Its three IP-based studios with visual integration – consists of equipment from German technical pioneer, Lawo – is capable of streaming live video from the studio to any Content Distribution Network (CDN), Social Media and other platforms.

As the only broadcast system integrator in Africa to have implemented a similar system, Nairobi-based BYCE Broadcast was contracted to set up the entire to-air chain. This involved equipping three state-of-the-art studios, a production room and a Central Technical Area (CTA), as well as the transmission of the broadcast signal.

Three key phases were planned to ensure the smooth and speedy progress of the project. These began with the equipment setup for Studio One, installing a 12-fader Lawo crystal mixing console with integrated router, plus advanced radio automation software with HD video playout capability (720p), and 6-channel video mixing software with integral CG and graphics generation to add the station’s logo, news crawls, weather info and custom legends.

The second step was the transmission area, which involved the erection of a 24m mast at the client’s site to facilitate a microwave point-to-point link to the Limuru broadcasting site where an 8-bay omnidirectional antenna provides a broadcast diameter of about 100km. At this point, the studio went on-air during the second week of December 2017.

The second studio is equipped with a 12-fader Lawo sapphire console – with the addition of more channel modules, a sapphire can be transformed into a true production mixing console, placing a total of 60 faders at an operator’s fingertips. Features such as Autogain and Automix enable the console to take control of the entire studio.

The third studio is a ‘virtual studio’, which is configured around Lawo’s R3LAY virtual console. Due to its portability, the R3LAY virtual mixing console offers NRG Radio the best fit for its requirements, both in terms of OB, studio operations and the aim to make the studio design special and unique – it’s a futuristic and cool setup, with very few components in studio.

In less than four months, NRG Radio was up and running as a visual-radio FM channel with an online audio and video stream – it can be found on 91.3MHz in the Nairobi area and on for audio/video streaming.

BYCE Broadcast also facilitated the training of the NRG Radio staff, including presenters, traffic and the managerial staff. The presenters went on-air by audio/video streaming with NRG Radio on 4 March 2018.

Automix and Autogain

AutoMix automatically adjusts the levels of active and inactive microphones, while keeping a constant ambient level. As a result, mixing and hosting a talk show becomes a breeze. The console takes over control of the microphone mix, while the talent simply conducts the interview. AutoMix reduces ambient noise from open microphones while it keeps the overall volume of the mix at a constant level. AutoMix also works perfectly as a ducking function for voiceovers live on air. Striving for even more simplification, with the Lawo AutoGain feature, the talent can calibrate all microphone signals easily and without understanding technical dB values and overloads. By the press of a button, AutoGain levels microphone analogue gains automatically within seconds, while the talent just talks into the microphone.
