Dynacord U120:1M-EU Product Highlights
Explore the key capabilities of the Dynacord U120:1M-EU mixer amplifier.
120 W
About 16 6 W ceiling speakers at 100 V.
Any Speaker Line
4 ohm, 8 ohm, 70 V or 100 V by DIP switch.
Paging
UCS-1 call station on MIC 1 with chime and override.
VOX Ducking
Music drops 0 to 45 dB when someone speaks on MIC 2.
Emergency Override
EMG input lets a voice alarm system take over.
4-Step Fan
Temperature-controlled fan for full power.
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.

Know before you buy
Quick answers about the U120:1M-EU, and how it compares.
Where does the U120:1M-EU fit?
A one-zone mixer amplifier for restaurants, schools, offices and mid-size Masjids: about 16 6 W ceiling speakers at 100 V. For several zones with background and foreground music, the V Series; for a voice alarm, Bosch PLENA VAS, PAVIRO or PRAESENSA.
Which paging microphone?
The UCS-1 call station on MIC 1: push-to-talk, override and the two-tone chime. It is the same as the older Bosch PLE-1CS, which also works.
U60, U120 or U240?
| Model | Power | 6 W speakers at 100 V* | Low cut | Cooling |
|---|---|---|---|---|
| U60:1M-EU | 60 W | 8 | 70 Hz | Fanless |
| U120:1M-EU | 120 W | 16 | 20 Hz | 4-step fan |
| U240:1M-EU | 240 W | 32 | 20 Hz | 4-step fan |
Same inputs, controls and size; choose by power. *With 20% headroom: 60 W x 0.8 / 6 W = 8.
What can I connect to a U Series mixer amplifier?
- MIC 1: microphone or line, 48 V phantom, and the UCS-1 call station on its 5-pin Euroblock (override and two-tone chime).
- MIC 2: microphone or line with VOX ducking: music drops 0 to 45 dB when someone speaks.
- AUX: two RCA inputs, stereo summed to mono, for music.
- EMG: line or 100 V override from a voice alarm system.
Output: 4 ohm, 8 ohm, 70 V or 100 V by DIP switch.
How is a U Series amplifier installed?
1U high and half a rack wide. The supplied brackets fit it alone in a 19" rack, two side by side in one rack space (also next to a V600:2), on a table or under a table.
Can it connect to a fire alarm or voice alarm system?
Yes. The EMG input (line or 100 V) overrides everything, so a certified voice alarm system can take over the speakers in an emergency. The amplifier itself is not EN 54-16 certified; for certified voice alarm use Bosch PLENA VAS, PAVIRO or PRAESENSA.
Where does each system stand: U Series, V Series or Bosch voice alarm?
| System | Made for | Zones | Music | EN 54-16 voice alarm |
|---|---|---|---|---|
| Dynacord U Series | One area: small shop, office, small Masjid | 1 | Background | No |
| Dynacord V Series | Hotels, restaurants, retail, gyms, offices, Masjid complexes | 8 per VZX-8 | Background and foreground | No |
| Bosch PLENA VAS | Small to medium buildings with voice alarm | 6, expandable | Background | Yes |
| Bosch PAVIRO | Medium to large buildings | 12, expandable | Background | Yes |
| Bosch PRAESENSA | Large and multi-building sites, IP based | Scalable | Background | Yes |
The V Series is made for paging plus background and foreground music. In a building that needs a voice alarm it can run music and paging day to day while PLENA VAS, PAVIRO or PRAESENSA takes over every zone through its EMG input in an emergency.
