Bosch PRAESENSA PRA-AD608 – 600W 8-Channel Amplifier

The Bosch PRAESENSA PRA-AD608 – 600W 8-Channel Amplifier   is a powerful, flexible, and highly efficient multi-channel amplifier designed for modern Public Address and Voice Alarm (PA/VA) systems. It delivers excellent speech intelligibility, flexible zoning, and advanced fault-tolerant operation through OMNEO IP networking and fully supervised audio paths.

With its compact design and ability to distribute power dynamically across eight independent channels, the PRA-AD608 is perfect for large multi-zone installations, including airports, campuses, shopping malls, industrial sites, public facilities, and transportation hubs.

🔹Bosch PRAESENSA PRA-AD608 – 600W 8-Channel Amplifier Efficient 8-Channel Power Amplification

The PRA-AD608 provides:

• 600W total output shared across eight channels

• Transformer-less 70/100V outputs with galvanic isolation

• Automatic per-channel power adjustment based on connected load

• Integrated spare amplifier channel for fail-safe redundancy

This dramatically reduces the number of amplifiers required and lowers system costs.

🔹Bosch PRAESENSA PRA-AD608 – 600W 8-Channel Amplifier Sophisticated Loudspeaker Topology Support

The amplifier includes:

• A/B outputs on all channels for redundant wiring

• Support for Class-A loop wiring with end-of-line devices

• Load-independent frequency response for consistent audio quality

• Supervised connections on all outputs

Ensuring robust and compliant emergency routing for EVAC systems.

🔹Bosch PRAESENSA PRA-AD608 – 600W 8-Channel Amplifier Superior Digital Audio Quality with DSP

Using OMNEO Audio-over-IP (Dante/AES67 compatible), the PRA-AD608 offers:

• 48 kHz, 24-bit audio quality

• High signal-to-noise ratio

• Minimal distortion and crosstalk

• Per-channel DSP with EQ, limiting, and delay

• Zone-specific acoustic optimization

The result is crystal-clear speech and high-quality background music across all zones.

🔹 Full Supervision & Fault Monitoring

The amplifier continuously supervises:

• Channel operation

• Loudspeaker line integrity

• End-of-line devices

• Network connection health

• DC power redundancy

Faults are reported instantly to the PRAESENSA controller for diagnostics and compliance.
