Crown CTD-2125 – 2-Channel 125W Dante Installed Amplifier

Product Overview

The Crown CTD-2125 is a 2-channel, 125W per channel Dante-enabled installed sound amplifier designed for modern networked AV environments. Supporting both Dante and AES67 standards, it integrates seamlessly into IP audio networks, eliminating the need for traditional analog signal runs. The CTD-2125 also supports 70V/100V distributed audio output for wide-coverage commercial installations. Its compact rack-mount form factor and powerful feature set make it an ideal amplifier for conference rooms, hospitality venues, and retail environments.

Product Description

The Crown CTD-2125 delivers 125 watts per channel across two output channels, providing reliable amplification for installed sound applications. Dante networking allows audio signals to be routed over standard Ethernet infrastructure, dramatically simplifying system design and reducing cabling costs. AES67 compatibility ensures interoperability with other AoIP (Audio over IP) systems and devices, giving integrators greater flexibility in system design. The CTD-2125 supports 70V and 100V constant-voltage output, enabling efficient distribution to multiple loudspeakers over long cable runs. Onboard DSP provides equalization, delay, and protection processing without requiring additional hardware. The amplifier's compact chassis fits standard 19-inch racks, making it suitable for AV closets, equipment rooms, and modular AV systems. Crown's DriveCore amplification technology ensures high efficiency and low heat generation, reducing operational costs and extending system lifespan. Front panel indicators provide real-time status feedback for quick diagnostics. Universal AC input accommodates global power standards. The CTD-2125 is backed by Crown's proven reliability and Harman's worldwide service network.

Frequently Asked Questions

What is Dante networking and why does it matter for installed sound?

Dante is an industry-standard audio-over-IP protocol that allows high-quality audio to be transmitted over standard Ethernet networks. It eliminates long analog cable runs, reduces installation time, and enables flexible routing from any Dante source to the CTD-2125.

Is the CTD-2125 compatible with non-Dante AoIP systems?

Yes. The CTD-2125 supports AES67, an open interoperability standard for audio-over-IP, allowing it to work with other AES67-compliant systems and devices.

Does the CTD-2125 support 70V distributed audio?

Yes. The amplifier supports both 70V and 100V constant-voltage output, making it compatible with standard commercial distributed loudspeaker systems.

What DSP functions are available onboard?

The integrated DSP provides equalization, programmable delay, and dynamic protection processing, reducing the need for external signal processing hardware in smaller system designs.

How much rack space does the CTD-2125 require?

The CTD-2125 is built in a compact rack-mount chassis designed for standard 19-inch equipment racks. Please refer to the product datasheet for exact rack unit height.
