The DSPPA DMA6500U is a 500W six-zone mixer amplifier that accepts up to 12 DMA20 paging stations on two ports and runs from mains or a 24V emergency supply. It suits hotels, commercial complexes and multi-storey buildings with large speaker loads.
====
The DSPPA DMA6500U delivers 500W over six zones, enough for a commercial building with dozens of speakers. Picture a hotel in Madinah: soft music in the lobby, announcements in the restaurant, paging in the car park and alerts along the guest-floor corridors. Each of those areas becomes its own zone with its own knob on the same amplifier.
DSPPA DMA6500U for larger buildings
Rated output is 500W, the next step up from the DMA6350U once your speaker taps add up. The unit offers:
- 70V and 100V constant-voltage outputs, plus 4-16Ω.
- 6 zones with knobs and indicators and an FN key for zone selection.
- 4 mic inputs, 2 AUX inputs, an EMC emergency input and a line output.
- AC 220-230V supply and a 24V DC input.
Twelve paging stations on two ports
Two RJ-45 ports on the rear each take up to 6 DMA20 stations in a chain, 300 to 600 m from the amplifier. The same cable carries audio, zone selection and 24V power. In a hotel you might put one station at reception, one in the security room and one in the manager's office. Paging triggers forced cut, so the message is heard even in rooms where guests have turned their volume down.
Running through a power cut
The 24V DC input on the rear is intended for emergency power, and the AC and DC supplies can each be switched off. At full output the DMA6500U draws 600W from mains or 323.5W from DC; at idle it uses 40W on AC and 34.5W on DC. Those figures help your electrician size the battery bank or UPS.
Sample hotel zoning on 500W
- Lobby and reception: 12 ceiling speakers at 6W (72W).
- Restaurant and breakfast hall: 10 ceiling speakers at 10W (100W).
- Guest-floor corridors: 30 ceiling speakers at 3W (90W).
- Car park: 6 horns at 15W (90W).
- Musalla and meeting room: two more zones of ceiling speakers.
With the last two zones the total lands near 400W, leaving room to add speakers later.
Sources and priority
Background music can come from USB, an SD card, Bluetooth or the FM tuner. Priority runs MUTE, EMC, siren, MIC1, chime, paging stations, then music. Built-in protection covers overload, clipping, short circuits and over-temperature.
Typical projects
- Hotels in Makkah, Madinah and Riyadh.
- Small and mid-size shopping centres: shops, walkways and parking.
- Private hospitals: reception, outpatient clinics and waiting halls.
- Large mosques with wide courtyards.
DMA6500U, DMA6350U or DMA6650U?
All three share the chassis, inputs, zones and paging ports. The DMA6350U gives 350W, draws 450W and weighs 9 kg. The DMA6500U gives 500W, draws 600W and weighs 10.1 kg. The DMA6650U gives 650W, draws 800W on AC and 435W on DC, and weighs 11 kg. If your speaker load sits roughly between 300W and 400W, the DMA6500U leaves comfortable headroom.
Frequently Asked Questions
How much does the DMA6500U draw from a battery?
323.5W from the 24V DC input at full output and 34.5W at idle, according to DSPPA's table.
Can I page from more than one office?
Yes. It accepts up to 12 DMA20 stations, six per RJ-45 port, and each station selects the zones it pages.
DMA6500U or DMA500U?
Both are 500W. The DMA6500U adds 6 zones, paging station ports and 4 mic inputs; the DMA500U drives a single line without zones.
