Product description



DSP-B series professional network power amplifiers are adopted 24 Bit professional DSP audio CMOS chip. They are designed for long-distance audio system. It is preferred for gymnasium and large-scale audio system. These series power amplifiers can be adjusted manually and also can be controlled by computer. So it is very convenient for using. You can control up to 250 PCS power amplifiers by computer. The control distance can meet 1000 meters in theory (the length of the distance depends on different conditions). You can adjust the Gain, Equalizer specification, Crossover, Delay, Opposite phase, Limiter and so on for each power amplifier. You also can adjust the Stereo, Mono, Bridged and so on. You also can adjust the specification above by manual completely without connecting to the computer.


1. This amplifier is noise-free

Without input connection, AODA  DSP-B series amplifiers have no noise even the volume have reached the maximum. This will increase the quality of your work.


2. The amplifier has multiple built-in intelligent protection systems 

The AODA   DSP-B series amplifiers integrate anti-impact function of the power’s soft start, DC output protection, long-time over-heat protection and power-on delayed function. These can speedy protect the circuit when short circuit and over loading happen, and the performance will not be intermitted.


3. Efficient automatic variable speed cooling system 

AODA   DSP-B series amplifiers have tunnel-shape automatic cooling systems, which protect the amplifiers to operate for a long time safely.


4. The unit has various input/output connectors

AODA   DSP-B series amplifiers have various input/output connectors. An amplifier has a three-position sensitivity switch for choosing level, stereo, bridged-mono, and parallel mono. It can connect the speaker speedy by the professional SPEAKON. 


5. The unit has consummate working status indications

The LED indicator on the front panel of Aoda amplifier makes you clear the working status of the amplifier, making operation and adjustment easier.
