House Of Worship Selects Jünger Audio Solution

Jünger Audio's D*AP4 Digital Audio processors have been selected to control and regulate audio for the Pentecostal Church Filadelfia's television and radio output.

The organisation has installed Jünger Audio loudness processing to control the entire audio output from the media centre in its new Q42 complex in Kristiansand, Norway. The complex incorporates housing for the elderly, a congress centre, a leisure centre, a 1,300-capacity concert hall, a small hotel, a restaurant and a media centre complete with TV, radio and sound control studios and an edit suite.

The media centre handles live video streaming of services, the recording of services for later broadcast on linear TV, and a 24-hour DAB Christian radio channel – Radio 3,16 – that reaches 70% of Norway.

Sigurd Schaathun, Technical Advisor for Filadelfia Kristiansand, said: "In the middle of this are two Jünger Audio D*AP4 LM digital audio processors, which control the audio levels of all content before it exits the building. We had to juggle the budget to make room for this technology, but it was the best money we ever spent because it has delivered what we need: transparent loudness processing for our live stream, recordings and national DAB radio."

As the church's audio content consists of music and speech, Schaathun needed a solution that could balance loudness across wide dynamic range. Jünger Audio's digital audio processors incorporate the company's proprietary Level Magic algorithm, which offers audibly transparent loudness processing without colouration, pumping, breathing or distortion. Aimed at radio and television companies, these processors allow broadcasters to take control of loudness and level in stereo and surround, ensuring that they deliver exceptional audio quality while staying within the boundaries of all specified loudness regulations.

Another factor in the church's decision to invest in Jünger Audio technology was its desire to comply with the EBU R128 loudness standard for broadcast audio, which has now been widely adopted by broadcasters in Norway. Level Magic features specific profiles to comply with virtually all national and international loudness regulations and requirements, including EBU R128.

"We wanted a processor that could get the best possible sound to our audience," Schaathun added. "As we are a volunteer organization, we have limited skilled personnel to mix broadcast audio perfectly; in fact, we often just take a matrix from the FOH and mix with a pair of audience microphones. The Jünger Audio processor straightens the levels and is totally transparent; we have none of the pumping associated with peak processing."

The Q42 media centre has one of its D*AP4 LM processors configured for two stereo signals – one set at broadcast standard -23 LUFS for recording linear TV and the other for the stream on Facebook and the internet, which is trimmed to -15 LUFS.

Jünger Audio's Spectral Signature dynamic EQ is a tool that offers automatic and dynamic EQ control to balance spectral differences. By analysing incoming audio and comparing its spectrum with individually predetermined voice 'fingerprints', the unit can automatically apply dynamic EQ corrections to give a consistent sound. This feature is useful to radio broadcasters who want to create an aural identity for their radio station because the spectral sound management principles allow the unit to measure specific voice recordings and use these sound fingerprints as a reference. The Spectral Signature algorithm matches all subsequent live recordings to these fingerprints, thus creating a dedicated 'station sound'.

The Pentecostal Church Filadelfia’s first D*AP4 LM unit was installed and configured by Jünger Audio's Norwegian distributor Lydrommet. The simplicity of the software meant that the church could configure its second unit.
