Tunnel Horn

Delivering Intelligibility

Road Tunnels provide unique acoustical challenges which require a dedicated solution. HARMAN developed the ABF tunnel horn specifically to address the needs of the tunnel market. These products feature high SPL capability and enhanced water ingress protection. The ABF’s ability to produce high sound pressure levels with negligible distortion make it ideal for noisy traffic tunnels.

Networked Audio Management

  • Networked Amplifiers - High Power, Ultra-Reliable

    PB Series Amplifiers drive the ABF260 tunnel horn and other loudspeaker systems for egress and cross-passages. They feature on-board DSP allowing gain, EQ, delay and other parameters to be controlled remotely via the WinControl Server. They can be fully monitored and feature automatic fault detection and reporting. Inputs may be either analogue audio (balanced audio) or networked digital audio via DANTE™.

  • WinControl Server - Control, Monitor & Interface

    Our WinControl Server empowers simple control and monitoring of the audio system as well as an interface to the Tunnel SCADA via its API. In addition to these features, the WinControl Server has a built in .wav player to play pre-recorded audio messages to tunnel users. The connection between WinControl and the PB Series amplifiers is via DANTE™.

  • System Optimization - Maximizing Intelligibility

    The optimization of an audio system is critical to ensuring that communications can be heard clearly and intelligibly. In the harsh environment of a tunnel with traffic, fan and reverb noise, this becomes even more important. For this reason, HARMAN developed OpSTImizer software to maximize message clarity and allow users to get the very most from their Tunnel PA System.
