Crown CTD-2125 - Comtech Dante 2X125W Amplifier

Crown CTD-2125 — ComTech D Amplifier with Dante, 2x125 W and Power Sharing

The Crown CTD-2125 is a 2x125W installation amplifier with asymmetrical power sharing , allowing its two channels to share up to 250W in any proportion. It features built-in DSP for room and speaker tuning, with JBL SpeakerTunings pre-installed for select models (including the JBL Control 400 in-ceiling series), streamlining optimization for HARMAN solutions. Configuration is done from a browser using the WebUI , with no proprietary software required.

For audio networking, it offers Dante inputs and outputs with redundancy support and selectable Dante output tap points (pre-processed analog, speaker preset, or post-speaker preset) for easy routing and monitoring. Control integration is simplified with HControl for native communication with BSS OMNI and AMX MUSE , plus a third-party API and GPIO ports (multiple GPIs and dedicated GPO ). Outputs are Lo-Z/Hi-Z switchable, supporting 4/8 Ω and 70/100 V in any combination. Its 1 RU, 1/2 rack-width chassis allows rack, under-desk, or wall mounting with the included hardware.

Main features

• Power : 2 × 125 W with all channels equal; up to 250 W per channel with split (Lo-Z and Hi-Z).
• Power distribution : both channels share 250 W in any proportion.
• Audio over network : Dante with inputs and outputs and redundancy (Primary/Secondary).
• Selectable tap point for Dante outputs: analog pre-processing, pre-tuning or post-tuning.
• DSP integrated with JBL SpeakerTunings out of the box.
• Switchable Lo-Z/Hi-Z outputs : 4/8 Ω and 70/100 V in any combination.
• Web UI for configuration without additional software; management with AVX Manager in large installations.
• Monitoring : pilot tone , Load Monitoring and source priority switching .
• Control : HControl (BSS OMNI and AMX MUSE), API for third parties, GPIO with GPI and GPO.
• Format : 1 RU, ½ rack width; 43 × 220 × 358mm ; 2.9 kg .

Benefits for integrators and users

• Real power flexibility to adapt each channel to the demand of the area without changing stages.
• Less hardware : DSP + Dante I/O + WebUI reduce auxiliary equipment and startup times.
• Interoperability with HARMAN ecosystems (BSS/AMX) and third-party control via API.
• Service continuity thanks to Dante redundancy and monitoring tools.
• Space-efficient : 1 RU half-width chassis with versatile mounting options.

Use cases

• Retail, hospitality and leisure : multi-zone ambient music with levels and equalization tailored to each area.
• Corporate and education : Meeting/training rooms with room-specific audio profiles and centralized control.
• Hotels and resorts : mix of 70/100 V lines with specific areas in low impedance.

Frequently Asked Questions

• Can I mix Lo-Z speakers and 70/100V lines? Yes, the outputs are Lo-Z/Hi-Z switchable and can be combined depending on the project.
• Does it have Dante redundancy? Yes, it supports redundant Dante configurations (Primary/Secondary).
• Do I need proprietary software? No, all configuration is done from the browser using the WebUI.
• What is the maximum power output per channel? Up to 250 W per channel (power split), both in Lo-Z and Hi-Z.
