Description

Bosch IFB-325 Portable Single Channel IFB Beltpack W/ 1/4IN Jack

Overview

The Bosch IFB-325 is a portable, single-channel IFB (Interruptible Foldback) beltpack designed for critical communication workflows. It provides a reliable audio interface for talent or crew to receive cues and instructions without disrupting their primary audio feed. This unit is essential in broadcast, live event production, and theater environments where precise timing and clear communication are paramount. The IFB-325 model specifically includes a 1/4 inch jack for versatile connectivity.

Compatibility

This IFB beltpack is designed to interface with standard IFB systems and audio consoles that provide a balanced mono microphone-level input and a balanced mono line-level output. It is compatible with professional audio equipment commonly found in broadcast studios, live sound mixing consoles, and intercom systems requiring a dedicated cueing channel.

Installation Notes

No specific installation tools or complex wiring are required beyond standard audio cable connections. The unit is designed for portable use and can be clipped onto a belt or placed on a surface. Ensure the connected audio source provides appropriate signal levels to avoid distortion or low volume. The 1/4 inch jack accommodates standard audio cables for connection to mixers or other audio distribution points.
