Crestron DM-NAX-AMP-X300 4-Channel 300W Amplifier

Product Overview

The Crestron DM-NAX-AMP-X300 is a 4-channel, 300W flexible output amplifier designed for distributed audio installations in commercial AV environments. As part of the Crestron DM NAX Intelligent Audio ecosystem, it supports Audio over IP (AoIP) distribution alongside conventional analog inputs, and is capable of driving both 70V/100V high-impedance speaker lines and low-impedance loads. Its 1U rack-mount form factor makes it suitable for standard equipment rooms and AV closets.

Product Description

The DM-NAX-AMP-X300 delivers 300W of total output power across four channels, giving AV integrators a compact, single-rack-unit solution for multi-zone distributed audio. The amplifier accepts both balanced and unbalanced analog audio inputs and includes phantom power support for condenser microphones, enabling direct connection of professional-grade microphones without an external preamp or power supply.

Support for 70V and 100V high-impedance output configurations makes the DM-NAX-AMP-X300 well suited to large-venue distributed speaker systems — conference centers, houses of worship, healthcare facilities, and corporate campuses — where long cable runs and multiple speaker taps are required. Low-impedance output is also supported for near-field or higher-power applications.

Integration with the DM NAX network allows the amplifier to participate in an AoIP distribution architecture, enabling centralized management and flexible audio routing across a facility. The universal 100–240VAC power input ensures compatibility with international installations without requiring external power conversion.

Technical Specifications

FAQs

Is the DM-NAX-AMP-X300 compatible with 70V distributed speaker systems?

Yes. The amplifier supports both 70V and 100V high-impedance output configurations, making it directly compatible with standard distributed audio speaker systems using transformer-tapped loudspeakers.

Does the DM-NAX-AMP-X300 require a DM NAX network to operate?

No. The amplifier can be used with conventional analog audio sources via its balanced or unbalanced inputs independent of the DM NAX network. DM NAX network connectivity enables AoIP distribution and centralized management when deployed within a Crestron DM NAX system.

Can condenser microphones be connected directly to the amplifier?

Yes. The DM-NAX-AMP-X300 provides phantom power, allowing condenser microphones to be connected directly without a separate power supply or preamp.

What rack space does the DM-NAX-AMP-X300 require?

The amplifier occupies 1U of rack space (1.74 in. height) and is 11.03 in. deep, fitting standard 19-inch equipment racks.

Is this amplifier suitable for international installations?

Yes. The universal 100–240VAC power input supports both North American and international mains voltages without modification or external adapters.
