Product Overview

The Dolby 32-channel multichannel amplifier (DMA32301) is the highest channel-density model in the family, built for large premium auditoriums and full Dolby Atmos speaker counts. A single 4U rack-mount cinema amplifier provides 32 channels of amplification, consolidating the hardware of many discrete amplifiers into one chassis. As a digital-input Dolby Atmos amplifier, it takes audio over Dolby Atmos Connect rather than an analog module, making it a clean fit for immersive cinema designs. It is part of the Dolby Professional collection at Creation Networks.

Product Description

The DMA32301 is a 32-channel rack-mount cinema amplifier that uses an advanced high-density Class D design to fit 32 channels of amplification into a single 4U chassis. In the 32-channel configuration it delivers 300 W per channel at 8 ohm and 4 ohm, with 600 W available in two-channel bridged mode at 8 ohm, providing the channel count required for full Dolby Atmos speaker layouts in large auditoriums. Unlike the 16- and 24-channel models, the 32-channel DMA32301 does not include the CAT1416 analog input module; it is driven by digital audio over two Dolby Atmos Connect Ethernet ports, which suits modern immersive cinema processors and screening rooms designed around digital audio distribution. A custom-built power supply provides redundancy, power sharing, operational monitoring, and fault detection, and the unit automatically detects maximum and net power and adjusts channel gains based on power supply, load, and fault conditions. Its high channel density makes the DMA32301 a strong choice for premium large-format auditoriums and multi-screen cinema complexes where a single amplifier must drive a large overhead and surround array. Web-based control, SNMP monitoring, front-panel status and signal-presence LEDs, and a front-panel USB 2.0 maintenance port support remote management across an installation. For auditoriums that still rely on analog 5.1/7.1 processor outputs, the 16-channel DMA16302 and 24-channel DMA24302 include the CAT1416 analog input module.

Key Features

• Highest Channel Density in the Family — The DMA32301 provides 32 channels of amplification in a single 4U chassis, ideal for full Dolby Atmos speaker counts in large auditoriums.
• High-Density Class D Design — One unit consolidates the amplification of many discrete amplifiers, reducing the hardware you install, power, and maintain in the amplifier rack.
• 32-Channel Power Output — In the 32-channel configuration each channel delivers 300 W at 8 ohm and 4 ohm, with 600 W available in two-channel bridged mode at 8 ohm.
• Digital Dolby Atmos Connect Inputs — The amplifier is driven by digital audio over two Dolby Atmos Connect Ethernet ports rather than an analog module, fitting immersive cinema designs.
• Redundant Power Supply — The custom-built power supply includes built-in redundancy, power sharing, operational monitoring, and fault detection to keep large auditoriums running reliably.
• Adaptive Power Management — The unit automatically detects maximum and net power availability and adjusts channel gains based on power supply, load, and fault conditions.
• Web and SNMP Management — A web-based user interface, SNMP monitoring, front-panel status and signal-presence LEDs, and a front-panel USB 2.0 maintenance port allow control from anywhere on the theater network.
• Flexible Terminal-Block Outputs — High-voltage terminal-block outputs accept 8-24 AWG loudspeaker wire for direct connection to auditorium speaker arrays.

Typical Applications

• Premium large-format auditorium
• Multi-screen cinema complex
• Movie theater auditorium
• Screening room
• House of worship with cinema-grade audio
• Broadcast studio

Technical Specifications

Frequently Asked Questions

Which cinema processors is the DMA32301 compatible with?

The 32-channel DMA32301 uses digital audio over Dolby Atmos Connect rather than the CAT1416 analog module, so it is intended for processors that output digital audio for immersive Dolby Atmos installations. It works alongside the Dolby CP950 processor in a digital signal chain.

Does the DMA32301 include the CAT1416 analog input module?

No. The 32-channel model does not include the CAT1416 analog input module. Audio is delivered digitally over Dolby Atmos Connect. If you need direct analog 5.1/7.1 processor integration, the 16- and 24-channel models include the CAT1416 analog input.

How is the amplifier installed in a rack?

The unit is a 4U rack-mount chassis measuring 19 in wide by 7 in high by 22 in deep. Plan for adequate rack support and airflow, and keep the operating environment within the 0 to 40 deg C range.

What are the power requirements?

The amplifier operates from 100 to 240 VAC, 50-60 Hz on a 20 A service through an IEC 320-C20 inlet (20 A max). The custom power supply is engineered to run at full load without tripping the AC mains breaker.

Can the amplifier be monitored remotely?

Yes. It provides a web-based user interface and SNMP for monitoring and control from anywhere on the theater network, along with front-panel status and signal-presence LEDs and a front-panel USB 2.0 maintenance port.

What is the warranty and lead time?

The manufacturer warranty applies. This product is available by quote; contact Creation Networks for current warranty terms, support options, and lead time, and see our theater and auditorium AV solutions for design assistance.
