DPA 4800 Digital Power Amplifiers.
Digital Power Amplifier
Digital Power Amplifier internal
DPA 4800 provides very high power and high quality audio performance.
PWM / class-d amplification and switch mode power supply with PFC.
The DA series are ideal for a range of applications ;
Mobile Disco ,
Theater use, ....
Switch Mode Supply
The power supply is the heart of a power amplifier, converting AC power to
clean DC for the audio circuitry. DPA 4800 uses a very high power switch-mode power
supply with power factor correction for stable high power and lo heat and weight.
DPA 4800 Features
DPA 4800 has all the features you should expect from a modern power amplifier and then some..
- Fast shut-down to protect the amplifier and the load.
Soft clipping circuitry - to protect the amplifier and the load from excessive overdrive.
- Very lo-frequency cut-off - to protect the speakers from subsonic damage.
- XLR inputs
Speakon outputs provide easy and stable connections.
- Low-noise variable speed fans with rear-to-front air flow keep amplifiers and racks
cool. DPA 4800 generates 1/10 of the heat of a conventional amplifier of the same wattage...
>85% total conversion efficiency from ac input
to speaker output
