Thanks to electronic tilting, the line arrays can be mounted flat on the wall and thus blend in unobtrusively with the room architecture in the Church.
Project description
Church sound reinforcement
In the summer of 2020, the Evangelical Reformed Christ Church in Allschwil (Switzerland) was equipped with a new sound system from Phoenix Professional Audio equipped:
The church, built in 1932, is the successor to a small neo-Gothic church of the Evangelical Reformed Church and impresses with its clear design language and timeless modernity. The concrete trusses in the interior of the nave and the striking beams create a unique impression of lightness, which is reinforced by the flood of light from the high windows.
The main focus when implementing the new sound reinforcement concept was not only on digital acoustic modernization, but in particular on the harmonious fusion of colors and shapes of the sound reinforcement system used with the church interior design.
The active DSP Beam Steering Line Arrays DIGIVOICE-350.16DSP2 (16 channel DSP) and DIGIVOICE-75.8DSP2 (8 channel DSP) speaker technology developed by PHOENIX Professional Audio has been used in the church. Thanks to the latest Beam Steering technology the speakers fit inconspicuously into the overall picture of your church. Beam steering enables continuous electronic controllability of sound aperture angle and tilt angle in the vertical direction in real-time – completely without mechanical alignment of the speaker systems (tilt). This means that the line arrays can be mounted flat against the wall and thus blend in unobtrusively with the interior architecture of the church. The active DIGIVOICE sound columns consist of software-controlled loudspeakers. Each DSP channel has its own Class-D power amplifier. The independent DSP channels enable individual, very precise speaker control and thus optimal adjustment to the individual acoustic room conditions.
Also the filigree MEX gooseneck microphones on the pulpit, altar and lectern merge with the noble church interior design and ensure perfect speech reproduction thanks to an extremely linear frequency response.
The Pre-Amp Mixer AMX-9-DSP-4ACD with Class-D power amplifier ensures more precise room equalization and excellent adaptation to the room acoustics. The preamplifier has been specially developed for professional sound reinforcement tasks in acoustically difficult buildings (building acoustics) and equipped with the latest technologies.
Furthermore, a radio system from MIPRO and a DSP audio matrix from Symmetrix with 8 analog mic/line inputs, 8 analog outputs and accessories are used in the church.

The line arrays offer excellent speech and music reproduction, uniform sound coverage over the entire sound reinforcement area and ensure the minimization of disruptive reflections.
