The 1-Ch. A-modules are PWM amplifier modules for external power supply (SMPS or linear) and they all have high efficiency,full 20Hz—22kHz) bandwidth
The 1-CH A modules can also be powered from an ASW-module, as an example the D1000ASW can power 1-2 D250A for a biamp or triamp configuration.

The 2-Ch. A-modules are PWM amplifier modules for external power supply (linear or SMPS) and they all have high efficiency, full bandwidth, they can be coupled in bridge mode for high power (mono) output. The 2-CH A-modules can also be powered from a linear power supply for simplicity if required.

The modules require a small heatsink or an aluminum bracket (not included), for most applications an aluminum backplate or similar will do fine as heatsink.

The modules can also be used to make 2-Ch. , 4-Ch. or more rack amplifiers, and multi-channel amplifiers for PA , Musical Instrument amplification, HIFI , Home Cinema , Installation or industrial usage.

For multi-channel applications such as high-power, high-end home cinema usage etc, we recommend using the above 1-ch or 2-ch amplifier modules, with SMPS if this is required or with a linear supply if this is preferred.

Feel free to ask us about preferred combinations , suitable power supply etc.

We are working on a flexible multi-channel solution , like a configurable amplifier where you can combine and add channels to suit specific use, more info later.

We have designs for 4-ch amplifier modules and 6-ch amplifier modules , contact us if you have applications to suit these and feel free to ask us for quotes etc. for all types of amplifier designs with or without integrated SMPS.
