Conference Room Audio System with 16 Bose Ceiling Speakers, 8-Channel Digital Mixer Amplifier, Wall-Mounted Mixer Inputs and Zone Volume Controllers

Inside the Design

This professionally engineered conference room audio system is designed to deliver clear, consistent audio coverage for spaces up to 8,000 square feet. Ideal for conference rooms, divisible meeting spaces, and hospitality environments, this meeting room audio system supports up to four independent zones that can be combined or separated as needed. Whether used for presentations, background music, or paging, this flexible setup adapts easily to changing room configurations.

At the core of this conference room sound system are sixteen Bose Professional DesignMax DM5C in-ceiling loudspeakers, providing balanced, full-range sound with excellent speech intelligibility and music clarity. Powering this system is the Pure Resonance Audio DZMA8125 8-Channel Digital Mixer Amplifier, which enables precise multi-zone routing and consistent output across all areas while maintaining efficient, reliable performance.

Zone-level operation is handled through integrated wall-mounted controls and input stations. The Atlas Sound WTSD-MIX31K wall-mounted mixer input panels allow users in each room or zone to connect directly to the system using microphone, line-level devices, auxiliary inputs, or Bluetooth streaming. This makes them ideal for presentations, lecterns, guest speakers, training sessions, or ad-hoc audio playback without accessing the main rack equipment.

For day-to-day operation, the Pure Resonance Audio DZC Digital Zone Controllers provide simple, intuitive local control over each area. Installed in each zone, the DZC controllers allow users to adjust volume levels independently, select or manage assigned audio sources, and fine-tune output for their specific room without affecting other zones. This ensures each space can operate independently while still being part of a unified system when needed.

With integrated Bluetooth capability, paging microphone support, and flexible source routing through the DZMA8125 platform, this system is built for both everyday use and professional applications. Its scalable architecture ensures seamless operation whether rooms are used independently or combined into larger event spaces.

System Configuration Notice

This system is designed for 70V (high-impedance) distributed audio operation with up to 4 independent zones. The Pure Resonance Audio DZMA8125 functions as a multi-channel digital mixer amplifier, where the 8 channels are used for audio inputs and internal mixing, not for separate speaker zones. In this configuration, the amplifier supports up to four 70V speaker zones total, which can be operated independently or combined depending on system design.

Proper configuration of zone routing, speaker tap settings, and input assignment is required for optimal performance. For assistance with system setup or deployment planning, please contact our sales team at (888) 256-4112 or [email protected].

It provides flexible routing, reliable power distribution, and centralized DSP-based control across multiple zones. Its compact design makes it ideal for installations requiring scalable, long-term performance in conference and hospitality environments.

Atlas Sound WTSD-MIX31K Wall Mixer Input Panels

The Atlas Sound WTSD-MIX31K wall-mounted mixer panels provide local audio input access at the zone level. Each unit supports microphone, line-level devices, auxiliary connections, and Bluetooth streaming, allowing users to directly connect laptops, mobile devices, microphones, or presentation systems. This makes them ideal for meetings, training sessions, guest speakers, and wireless audio playback without requiring access to the main equipment rack.

Pure Resonance Audio DZC Digital Zone Controllers

The Pure Resonance Audio DZC digital zone controllers provide intuitive, wall-mounted control for each zone. Users can independently adjust volume levels and manage assigned audio sources within their space, ensuring localized control without impacting other zones. This allows staff or occupants to quickly adapt audio levels for meetings, presentations, or background music with simple tactile control.

Atlas Sound WTSD-COVER Security Covers

The Atlas Sound WTSD-COVER enclosures protect the wall-mounted mixer panels from tampering or unauthorized adjustments. Designed for durability, these lockable covers are ideal for public and commercial environments where equipment security is essential.
