In May 2024, the Parish and Pilgrimage Church of Mariae Geburt in Anzing (built between 1677 and 1681), in the Upper Bavarian district of Ebersberg, was equipped with a new sound reinforcement system from PHOENIX Professional Audio.

The Roman Catholic parish church Mariae Geburt, a former pilgrimage church, is a listed historical monument and underwent extensive renovations from 2023 to 2024.

The Phoenix Professional Audio team was tasked with installing a modern sound reinforcement system in the parish church, including a induction loop system for the hearing impaired. Particular attention was paid to excellent speech intelligibility, ease of operation, and high reliability.

The professional passive directional column speakers K4-30F, K4-40F, and K4-120F were installed to provide sound for the nave, the gallery, and the area below the gallery.

The K4 column speakers are specially designed for sound transmission in acoustically challenging rooms with long reverberation times, such as churches. The slim cabinet, made of specially shaped aluminum profiles and a light powder coating, is particularly sturdy and unobtrusive in design, allowing the speakers to blend seamlessly into the historic interior of the Anzing church without altering the style and aesthetics of the sacral building.

The K4 column speakers from Phoenix, whose frequency-independent directional sound radiation is limited to the audience area, ensure the best speech reproduction during sermons and readings and optimal sound quality for choir singing and concerts.

The column speakers are powered by the DSP-controlled POWERVOICE PV-DSP-4ACD.9.4.2X digital automatic mixing amplifier.

The automatic mixer is equipped with two Class-D digital amplifiers, phantom power, a HPF filter (100 Hz), a MIC-LINE, a digital automatic system, an audio matrix, conference configuration/priority, a dynamic compressor-expander-limiter function (for dynamic processing of audio signals and recordings), a de-esser, and an MP3 player with a BT receiver.

To ensure that the new speaker system is also clearly audible for the hearing-impaired, the main sound system was supplemented with a new induction loop, which was installed in the church. The ILA-450 induction loop amplifier was installed for this purpose.

The delicate MEG and MEX gooseneck microphones on the ambo, altar, and priest’s chair offer an extremely linear frequency response, ensure perfect speech reproduction, and blend visually with the elegant church interior architecture.

The church also received a new UHF wireless microphone system from MIPRO for flexible use during services. This includes an ACT-515 UHF True Diversity wireless receiver with an ACT-500H handheld wireless transmitter.

To ensure optimal speech intelligibility, the Phoenix team took on the acoustic measurement, level adjustment, room equalization and programming of the new sound system. With Phoenix’s modern sound technology, reverberation in the Church of the Nativity of Mary was significantly reduced. Spoken words and sentences are now perceived much more clearly and distinctly.
