Crown ComTech D Series amplifiers are designed for versatility, flexibility, and ease of installation. With both Dante inputs and outputs, built-in DSP, power sharing, Lo-Z/Hi-Z switching, and a simple to use web configuration interface, ComTech D amplifiers are ideal for meeting the changing demands of diverse installed audio applications.

The CTD-4125 delivers 125 watts per channel of legendary Crown amplification when all channels are driven equally. Asymmetrical power sharing enables the four channels to share the full 500W in any ratio, offering unparalleled flexibility.

Built-in DSP allows outputs to be tuned specifically for every application 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 the optimization of an all-HARMAN solution.

The amplifier can be configured through the intuitive web interface with any computer or tablet and without the need to install proprietary software. It uses HARMAN's HControl protocol to communicate natively with BSS OMNI Processors or AMX MUSE Automation Controllers and includes an easy-to-use API for integration with 3rd-party control systems.

This compact 1RU, ½ rack width device can be installed in a rack, under a table, or on a wall using the included mounting hardware.
