The DSPPA DMA60U is a 60W mixer amplifier with mic inputs, USB, Bluetooth and FM on board, plus 70V and 100V outputs for speaker lines. It fits a small prayer room, shop or clinic that needs one sound zone for the whole space.
====
The DSPPA DMA60U is a 60W mixer amplifier that brings microphones, USB music, Bluetooth and FM radio together in one 430 mm wide box. It is sized for places that need a single sound zone: a small prayer room, a retail shop, a clinic waiting area or a family istiraha.
DSPPA DMA60U key specifications
Rated output is 60W on mains power and the same 60W from a 24V DC supply, so a backup battery keeps the speakers at full level during a power cut.
- 4-16Ω output for standard speakers, plus 70V and 100V outputs for long speaker lines.
- AC 110-240V, 50/60Hz supply with 80W consumption.
- Mic response 120Hz to 12kHz; AUX response 80Hz to 15kHz.
- THD below 1%; SNR of at least 75dB on AUX and 71dB on mic.
Mic inputs and built-in music sources
MIC1 sits on the front panel for the imam or presenter. Two balanced inputs, MIC2 and MIC3, are on the rear with 48V phantom power, so a condenser gooseneck mic works without a separate power unit. MIC3 shares its jack with AUX2, and a rear switch picks which one is active.
For recorded Quran recitation or background music there is a USB port, Bluetooth and an FM tuner, plus two AUX inputs and an AUX OUT for feeding a recorder or a second amplifier. Each mic has its own volume knob, alongside AUX level, treble, bass and master volume.
Priority, alarm and remote control
The DMA60U decides what gets heard in this order: MUTE first, then the EMC emergency input, alarm and chime at the same level, then MIC1, then everything else. A signal from a fire panel on the EMC input overrides both the microphone and the music.
Chime 1 and Chime 2 buttons give a tone before an announcement. Short-circuit triggers on the rear start the siren (with its own alarm output) or mute the system. It supports an infrared remote, and settings are kept after a power cut.
Typical sites in Saudi Arabia
- A musalla in an office, warehouse or istiraha with an imam mic and a handful of ceiling speakers.
- A shop, salon or small cafe playing Bluetooth music with occasional mic announcements.
- A clinic calling patients over the waiting-room speakers.
- A small training room with a trainer mic and laptop audio on AUX.
Sizing speakers for 60W
On the 100V or 70V line you connect several speakers in parallel and set a wattage tap on each. Add up the taps and keep the total under 60W with some headroom. Eight ceiling speakers tapped at 6W, for example, come to 48W. The 4-16Ω output suits one or two speakers placed close to the amplifier.
DMA60U, DMA120U or DMA650U?
All three share the same front panel, inputs and priority logic. The DMA120U doubles the power to 120W and weighs 4.6 kg instead of 3.8 kg, while keeping the 70V/100V outputs and the 110-240V supply. The DMA650U delivers 650W but offers only 100V or 4-16Ω (no 70V tap) and needs its mains voltage set with a selector switch. If the building must be split into separately controlled areas, look at the six-zone DMA6250U series instead.
Frequently Asked Questions
How many ceiling speakers can the DMA60U drive?
Keep the total of the speaker taps under 60W with some headroom. Eight speakers on a 6W tap add up to 48W on a 100V or 70V line.
Does it work with a condenser mic?
Yes. The balanced MIC2 and MIC3 inputs on the rear provide 48V phantom power for condenser microphones.
Can it run from a battery during a power cut?
Yes. It has a 24V DC input, and DSPPA rates it at 60W on DC, the same as on mains power.
