Share This Post
The Harman 4D DSS Booster is a part of Bowers & Wilkins 4D Diamond Surround Sound used in BWM iX vehicles. This innovative sound system features no fewer than 30 speakers.
The analyzed device doesn’t have a particularly complicated design. The schematic which includes power and signal paths is implemented on one PCB. This main board on the other hand is covered by two enclosures. One of them is an ordinary metal plate. However, the other is more complex and is functionally a radiator. Combining it with two fans, this audio amplifier has a decent cooling solution.
