Wall module Audac WP205/B XLR microphone and 3.5 mm jack

The Audac WP205/B wall module provides a compact in-wall solution for connecting an XLR microphone and a 3.5 mm line input to a fixed audio installation. Designed for integration in conference rooms, classrooms, retail spaces and paging or background-music systems, this module offers professional microphone connectivity alongside a consumer-grade auxiliary input in a single faceplate. The black finish and slim profile allow discreet mounting in standard wall boxes while maintaining accessible front-panel connectors.

Advantages

The unit combines balanced XLR microphone input and an unbalanced 3.5 mm jack on one durable faceplate, simplifying wiring and saving wall space compared with separate modules. Balanced XLR connectivity supports professional microphone signals and reduces noise on long cable runs. The 3.5 mm jack allows easy connection of laptops, mobile devices or portable audio players for playback or presentations. Installation is straightforward in standard flush-mount boxes, and the robust construction is suitable for repeated use in public and institutional environments.

Suitable for

• Conference rooms and meeting spaces
• Classrooms and lecture halls
• Retail stores and hospitality environments
• Paging systems and background music installations
• Temporary presentations using consumer audio devices

Key specifications

• Connector types: 1 × XLR microphone input (balanced), 1 × 3.5 mm stereo jack (unbalanced)
• Mounting: in-wall faceplate for standard flush-mount electrical boxes
• Finish: black faceplate with professional-grade connector hardware
• Designed for fixed installations: low-profile, durable construction

How to use

Install the module in a standard in-wall flush-mount box and connect the building audio wiring to the rear terminals according to the system’s wiring plan. Plug a professional microphone into the XLR input for balanced mic-level signals; use the 3.5 mm jack to connect consumer devices or line-level sources. Adjust gain and routing on the connected mixer or amplifier to match the signal levels of the microphone and auxiliary source. Ensure cables are secured and strain-relieved behind the faceplate before final assembly.

Usage recommendations

For optimal audio quality, use low-impedance, balanced microphones with the XLR input and set preamp gain to avoid clipping. When connecting mobile devices via the 3.5 mm jack, use the device’s output level settings and, if available, a ground-lift or isolation adapter to minimize hum. Regularly check connectors for wear in high-use areas and follow local electrical and installation codes during mounting.
