Conference Room Audio Amplification Systems

The Atlas Learn system centers around receiver/amplifier units including the AL2430 mixer-amplifier and AL2450 amplifier/receiver, which serve as the hub for wireless microphone reception and audio distribution. These devices receive infrared signals from wireless transmitters and amplify the audio for distribution through ceiling-mounted speakers, creating an enhanced listening environment throughout the coverage area.

The AL-MAGPIE wireless infrared microphone forms the primary transmission component, worn as a pendant-style transmitter that captures the presenter's voice and broadcasts it via infrared to ceiling-mounted receiver domes. The microphone includes volume control for user adjustment, a panic button for emergency notification integration, and a 3.5mm input for optional headset or lapel microphone accessories. The rechargeable battery provides over eight hours of operation between charges.

Infrared dome receivers including the AL-IRDS mount on ceilings to receive the wireless microphone signals, with each dome including coaxial cable for connection to the amplifier unit. Multiple domes can be deployed to ensure coverage throughout larger spaces. The infrared technology provides reliable interference-free operation without the frequency coordination challenges of RF wireless systems.

Complete system kits like the MAGPIE1-2 and MAGPIE2-2 provide turnkey solutions including amplifiers, wireless microphones, charging stations, and infrared domes. These pre-configured packages simplify specification and ensure component compatibility while providing cost-effective bundled pricing.

These systems particularly benefit educational environments, enabling teachers to speak at conversational levels while ensuring all students clearly hear instruction.

Frequently Asked Questions

Q1. How does infrared audio transmission differ from RF wireless systems?

A. Infrared systems transmit audio using invisible light signals, which cannot pass through walls and therefore don't interfere with adjacent rooms. RF wireless systems use radio frequencies that can penetrate walls and potentially create interference. Infrared provides secure, reliable operation but requires line-of-sight between transmitter and receiver.

Q2. How many infrared domes are needed for a conference room?

A. Coverage requirements depend on room size, ceiling height, and layout. Small conference rooms may need only one dome, while larger classrooms or training rooms may require two or more domes for complete coverage. The receiver domes should be positioned to provide line-of-sight coverage throughout the presenter's movement area.

Q3. Can the Atlas Learn system integrate with existing room audio?

A. Yes, the Atlas Learn amplifier units include auxiliary inputs for connecting external audio sources and can output to existing speaker systems. The AL-EAGLE receiver provides line-level output for connection to separate amplifiers, enabling integration with installed audio infrastructure.

Q4. What is the purpose of the panic button on the AL-MAGPIE microphone?

A. The integrated panic trigger enables emergency notification when connected to compatible building safety systems. Pressing the panic button can activate alerts, initiate lockdown procedures, or notify security personnel, adding a safety dimension to the audio enhancement system.
