Overview

The 90° audio phase shifter introduces a phase shift across the audio band between two separate drivers providing the ability to install multiple loops in the same area for applications such as large areas, rooms with structural metal, theatres with balconies, confidential systems and adjacent locations. It includes a metal loss correction potentiometer that provides the ability to overcome the possibility of poor frequency response due to metal interaction. The shifter is provided power and audio input/output from ILD122, ILD300, ILD500 and ILD1000G drivers. It can be mounted in a 19” rack using the RM-1U rack mount tray or placed elsewhere in the equipment cabinet.

FAQ
Q What is spill or overspill?
A Overspill occurs when the magnetic field created by hearing loop can be heard outside of the looped area (such as a room). The field is “spilling” outside of the looped area and can affect other nearby loop systems.
