Dynacord U120:1M-US 120W Mixer Amplifier, 1-Channel

Product Overview

The Dynacord U120:1M-US 120W Mixer Amplifier is a compact, versatile commercial audio amplifier designed for small to medium-sized installations where reliable performance, audio quality, and flexible installation options are essential. With 120W RMS output power, the U120:1M-US is well suited for background music, paging, and clear voice announcement applications.

This 1-channel mixer amplifier features four inputs, including two microphone/line inputs with phantom power support, providing flexible connectivity for a variety of commercial audio sources. It supports 4-ohm, 8-ohm, 70V, and 100V speaker systems, making it suitable for both low-impedance and distributed commercial audio installations.

The Dynacord U120:1M-US is designed with installation flexibility in mind. Its compact half-rack-width, 1U-height chassis makes it a practical solution for locations where rack space is limited. The included mounting brackets allow for single or dual rack-mount configurations. Two amplifiers can also be mounted side by side in a single rack unit, helping maximize available space while increasing system capacity.

For paging and announcement applications, the amplifier includes an EMG Override input, contact override with a two-tone chime, and VOX ducking that automatically reduces background music when voice communication is detected. Built-in 70 Hz and 120 Hz high-pass filters help reduce unwanted low-frequency content and optimize audio performance.

The U120:1M-US can be used in a wide range of commercial environments, including restaurants, bars, retail stores, schools, houses of worship, museums, galleries, conference centers, and transportation facilities.

Commercial Audio Applications

The Dynacord U120:1M-US mixer amplifier is designed for a variety of professional commercial audio applications, including:

• Background music systems
• Voice paging and announcements
• Restaurants and bars
• Retail stores
• Schools and educational facilities
• Houses of worship
• Museums and galleries
• Conference centers
• Transportation hubs

Flexible Installation

The compact design of the U120:1M-US provides multiple installation options. Measuring approximately half the width of a standard rack unit, the amplifier can be installed in space-constrained environments while still providing professional commercial audio performance.

Included mounting brackets support both single and dual rack configurations. When two amplifiers are installed side by side, they can occupy a single rack unit, providing an efficient way to expand amplifier capacity while conserving rack space. The amplifier can also be installed on a desktop or underneath a counter where traditional rack mounting is not practical.

Advanced Audio Control

The U120:1M-US provides features designed specifically for commercial paging and background music systems. VOX Ducking automatically lowers background audio when a voice announcement is made, helping speech remain clear and intelligible.

The EMG Override input provides priority access for critical announcements, while the contact override and two-tone chime can be used to capture listener attention before an announcement begins.

The selectable 70 Hz and 120 Hz high-pass filters help remove unwanted low-frequency content and allow the amplifier to be optimized for different installation requirements.
