Flexible Power Sharing

The CTD-8125 delivers 125 watts per channel when all eight channels are driven equally. For systems that require different power levels across zones or loudspeakers, asymmetrical power sharing allows channels 1-4 to share up to 500 watts in any ratio and channels 5-8 to share another 500 watts in any ratio. This provides greater flexibility when powering mixed loudspeaker configurations from a single amplifier.

Built-In DSP and Speaker Tuning

Integrated DSP allows outputs to be tuned specifically for the needs of each installation and provides the ability to create custom speaker tunings. Factory JBL SpeakerTunings for select JBL models, including Control 400 Series ceiling speakers, are included to simplify system optimization in compatible HARMAN installations.

Dante Network Audio

Built-in Dante inputs and outputs provide flexible networked audio connectivity for modern installed sound systems. This allows the CTD-8125 to integrate into Dante-enabled environments while maintaining the flexibility required for commercial, hospitality, education, corporate, and other installed audio applications.

Web-Based Configuration

The amplifier can be configured through an intuitive web interface using a compatible computer or tablet without the need to install proprietary software. This simplifies setup, monitoring, and system adjustments during installation and ongoing operation.

System Integration

The CTD-8125 uses HARMAN's HControl protocol to communicate natively with compatible BSS OMNI Processors and AMX MUSE Automation Controllers. An easy-to-use API is also available for integration with third-party control systems.
