Mosques & Large Prayer Halls
A large prayer hall needs clear, even sound from the mihrab to the last row. With 240 W driving 100 V / 70 V speaker lines, the U240:1M covers wide prayer halls, galleries and courtyards, so every word of the khutbah, azaan and announcements is heard clearly and without distortion.
Islamic Centres, Madrasas & Imambargahs
Domes and hard surfaces make speech harder to understand. Paired with column or ceiling speakers, the U240:1M delivers dependable, intelligible sound for daily prayers, dars and gatherings, built to run reliably day after day.
Music Schools & Training Studios
: Music schools need instructors to be heard over the instruments. The U240:1M powers the room's PA for vocals, playback tracks and announcements, so teachers and students hear each other clearly during sessions.
Conference Rooms & Corporate Events
Presentations, seminars and training sessions all depend on the speaker being heard. The U240:1M delivers clear voice reinforcement from the podium to the back of the room, with enough power for large conference halls and event spaces.

Know before you buy
Quick answers about the U240:1M-EU, and how it compares.
Where does the U240:1M-EU fit?
A one-zone mixer amplifier for large restaurants, banquet halls and large Masjids: about 32 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.
