Product Description

Offering performance big enough to run two full range speakers and a modest subwoofer in a package small enough to fit in the palm of your hand the DB4.3 is an astonishing piece of tech. Equipped with a full suite of crossover controls and adjustments this amplifier will produce sound of a very high quality. The internal design is state of the art - built using the latest surface mount components around the impressive IR2093 chip platform the DB4.3 is a sure winner in any compact system. The unit also offers high level audio inputs for maximum compatibility with today's built in head units and versatile, powerful crossover functions in both high and low pass with variable levels. From a build perspective you will be pleased to see the recessed low level inputs, tough metal case and brass crossover and level potentiometers - this is a unit that has been long in develpment but which delivers on all fronts.

Version History

Prototype – Using the DB4.2 as a benchmark we designed a new model to incorporate the best quality IR2093 transistor platform with SMD technology. V1 – Power ratings to remain similar to DB4.2 but audio quality will be significantly better than the DB4.2 to justify the higher price point of the 4.3. Was originally intended to be launched as bluetooth but we were unhappy with the software and so we deleted this from the specification until we can see revisions. V1 – Production was initiated to a final design in Q3 2017 with first customer deliveries in early Q1 2018. The sonic performance of the DB4.3 exceeds expectations with musical performance that belies its class D architecture. Heat is well controlled and the high level inputs work very well indeed. Please note strange wiring of rear high level input, mentioned in instruction manual.
