Dynacord U120:1M-EU Mixer Amplifier
Everything you need to know about this 120W, 1-channel mixer amplifier before specifying it for your project
The U120:1M-EU is a 120W mixer amplifier used for background music and voice announcements in mid-sized commercial spaces such as restaurants, retail stores, schools, mosques and churches, offices, and conference centers. Its built-in mixer lets microphones, music players and a call station connect directly, with no separate mixer needed.
It has two mic/line inputs (XLR) with switchable 48V phantom power, two AUX inputs (RCA, stereo summed to mono) for music sources, and an emergency (EMG) input that accepts line-level or 100V signals. MIC1 also has a 5-pin Euroblock input for a paging call station with contact override.
Yes. The output can be set to 4Ω, 8Ω, 70V, or 100V using the rear DIP switches, delivering the full 120W in every mode. That's enough to drive a large number of ceiling or wall speakers on a single 70V/100V line.
The U120:1M-EU is 1RU high and half a 19" rack wide. The supplied brackets allow stand-alone rack mounting, side-by-side mounting with a second amplifier in one rack space, tabletop use, or under-table mounting.
The U120:1M offers twice the output power (120W vs 60W) and a wider frequency response (20 Hz to 20 kHz vs 70 Hz to 18 kHz). It also adds a temperature-controlled fan for demanding use. Inputs, controls and features are otherwise identical.
Yes. The EMG input accepts a line-level or 100V signal and overrides all other inputs when active. This allows integration with EVAC (Emergency Voice Alarm Communication) systems.
Yes. The CCS 1000 D is plug-and-play, so integrators and technicians can set it up quickly without complex configuration. Participants get a straightforward device with simple controls.
When someone speaks into MIC2, the U120:1M-EU automatically lowers the background music so the voice comes through clearly. Both the ducking depth (0 to 45 dB) and the voice threshold are adjustable.

U120:1M-EU Mixer Amplifier, 120W, 1-Channel
The Dynacord U120:1M-EU is a 120W, single-channel mixer amplifier that combines a 4-input mixer and a Class D power amplifier in one compact, half-rack 1RU unit. It's ideally suited to background music and clear voice announcements in bars and restaurants, retail outlets, education, houses of worship, museums and galleries, transport hubs, and conference centers.
It delivers full power into 4Ω, 8Ω, 70V, or 100V loads with a wide 20 Hz to 20 kHz frequency response, so it can drive more speakers and larger spaces than the smaller U Series models. VOX ducking, a 2-tone chime and a priority emergency input make sure announcements are always heard over the music. It runs on silent convection cooling, with a four-stage temperature-controlled fan that switches on only under heavy load or high heat.
Premium 120W Single-Channel Mixer Amplifier
A compact half-rack Class D mixer amplifier combining a 4-input mixer and a 120W amplifier for background music and clear voice announcements.
Output Power & Performance
Rated Output: 120 W. Output Modes: 4Ω / 8Ω / 70V / 100V at full power. Frequency Response: 20 Hz – 20 kHz. Distortion: < 0.5% at rated power. Signal-to-Noise: > 100 dB.Four Inputs + Emergency Override
2 mic/line inputs with switchable 48V phantom power, 2 RCA AUX inputs for music, and a priority EMG input (line or 100V).VOX Ducking
Automatically lowers background music when a voice is detected on MIC2, with adjustable ducking depth (0–45 dB) and threshold.Call Station Input & 2-Tone Chime
The MIC1 Euroblock input supports a paging call station with contact override, plus a selectable 2-tone chime before announcements.
Fanless, Energy-Efficient Operation
A single RJ45 (AES72-1E) input carries both channels. It also has a 6-pin Euroblock analog input, Euroblock speaker outputs and a Ready/Fault relay.
Complete System Integration
Mounts side by side with another U Series amplifier in a single rack space, pairs with the PLE-1CS all-call station for paging, and has an RCA line output that feeds a U Series power amplifier to expand coverage.
Compact Size, Complete Connectivity
The U120:1M-EU measures just 218 × 44.2 × 217.7 mm (W × H × D) and weighs 1.9 kg. It takes up half the width of a single 19" rack unit, and with rack ears fitted it spans the full 483 mm (19") rack width.
All connections sit on the rear panel: two XLR mic/line inputs, two RCA AUX inputs, a 5-pin Euroblock for a call station, a 2-pin EMG input, an RCA line output, and a 4-pin Euroblock speaker output with separate LoZ and HiZ terminals.
Mosques
Clear speech matters most in a prayer hall. The U120:1M drives 100 V / 70 V speaker lines across courtyards, prayer halls and corridors, so the khutbah, announcements and azaan reach every corner at an even level. It's a good fit for small to mid-size mosques, or as a dedicated amplifier for one area of a larger complex.
Café / Food court
Background music sets the mood in busy open-plan seating areas. With a mixer and power amplifier in one compact unit, the U120:1M lets you play music from a phone, laptop or media player and make staff announcements, all from one easy-to-use system.
Bars, Lounges & Hospitality Venues
In lounge and bar areas, the right soundtrack keeps guests settled in. The U120:1M is a reliable, always-on music source for counters, lounges and waiting areas, and a mic input is ready for announcements when you need one.
Restaurants & Fine Dining
In an upscale dining room, the sound should be felt rather than noticed. Paired with ceiling or surface-mount speakers, the U120:1M delivers smooth, low-level background music across the dining area and gives staff simple volume control throughout service.
