FT624 Audio Distribution Unit | Multi-Device Connection for Radio Systems

The FT624 Audio Distribution Unit (Überleitverteiler FT624) is a professional interface designed to connect multiple control units in parallel to a single communication line using 2-wire technology. The unit ensures proper impedance matching and stable audio signal distribution across all connected devices, making it ideal for dispatch centers, industrial communication, and public safety applications.

Key Features:

• Multi-Device Connectivity – Connects 2 to 6 control units to a single communication line.
• Standardized 600 Ohm Impedance Matching – Ensures stable and interference-free audio transmission.
• 2-Wire Parallel Communication – All connected devices receive the same signal simultaneously.
• Scalability & Cascading – Multiple FT624 units can be connected together for larger installations.
• Compact & Lightweight Design – Easy to install and integrate into existing communication systems.

Available Versions & SKUs:

• FT624-2 – Supports 2 control units, signal attenuation: 6 dB.
• FT624-3 – Supports 3 control units, signal attenuation: 9.5 dB.
• FT624-4 – Supports 4 control units, signal attenuation: 12 dB.
• FT624-6 – Supports 5 to 6 control units, signal attenuation: 14.5 / 15.6 dB.

Connection & Setup:

Standard Configuration

The FT624 Audio Distribution Unit connects multiple control devices (ST1-ST11) to a common communication line (ST12). Each device maintains an impedance of 600 Ohm, ensuring uniform signal distribution.

Cascading for Large Installations

If additional control devices are required, multiple FT624 units can be cascaded to extend the number of supported connections.

Wiring & Integration

The unit uses screw terminal connectors (ST1-ST12) for secure wiring and easy installation in existing radio networks.

Application Example:

The FT624 allows multiple dispatch consoles to share a single radio system without interference. Each console can send and receive signals in real-time, maintaining consistent audio quality across the network.
