Church PA
In May 2024, the Roman Catholic parish church of St. Martinus in Hirrlingen, a municipality in the Tuebingen district of Baden-Wuerttemberg, was equipped with a new sound system from PHOENIX Professional Audio.
The passive K4 directional column speakers form the church’s main sound reinforcement system.
The column speakers consist of highly efficient neodymium tweeter systems in the HF frequency range and specially spaced 3.5″ broadband drivers in the LF/MF frequency range, ensuring improved speech intelligibility during services.
The passive speakers of the K4 series are powered by the DSP-controlled digital automatic mixing amplifier PV-DSP-4ACD.9.4.2X with Class-D power amplifier.
The Phoenix automatic mixer is specially designed for sound transmission in acoustically challenging spaces such as churches and is equipped with the latest technology.
The integrated de-esser dynamically attenuates “sss” and sibilance, and the built-in compressor-expander function is used for dynamic processing of audio signals and recordings. The new amplifier ensures more precise room equalization and excellent adaptation to the room acoustics in St. Martinus Church.
Phoenix “MEG” and “MEX” series gooseneck microphones were used at the altar and ambo.
The church also received a new UHF wireless microphone system for flexible use during services: This included a 2-channel handheld/bodypack transmitter set with a UHF receiver from MIPRO (Phoenix PA is an official MIPRO distributor).
The Phoenix team, which has specialized in church sound systems for over 20 years, also took care of the measurement, leveling, room equalization and programming of the new sound system in Hirrlingen.
