Product description

Now shipping Version 2 of this product - Updated for more even more flexibility!! – New features are variable high and low pass filters on each channel. This enables the amp to be used in a wide variety of applications, from subwoofers to mid range and tweeters. We know that a variable filter is much better than a fixed one as almost all speakers require a different crossover point. We’ve made the HPF on one pair of channels go to 3.5khz and the low pass on the other pair do Also updated are the screw down terminals which accept power wire with a larger cross section for more power. The DB4.2 punches way above its weight. And it’s a knockout! This tiny Class D 4 channel amp delivers similar power to the DB4.1, but measures in at little more than 13cm wide and 5cm deep. Because of its compact form factor, this amp lends itself very well to a number of applications. Where other amps would be unsuitable due to size and weight restrictions, the DB4.2 will happily fit into a dashboard or glove box. The minimal weight and class D topology mean it’s the perfect amp for 12v portable systems and motorcycles! Bassface took the growing 12v portable sound system culture into account in a big way upon designing this amplifier. Combining exceptionally high efficiency, low weight and modest power output with advanced customisable crossover circuitry we have created an all in one turnkey solution for numerous sound requirements. It is bridgeable to 4 ohm so you can run 2 speakers and a subwoofer – all from something that will fit in the palm of your hand!

Prototype – Realising class D technology had come so far as to be able to make amps so small and with such high power, here at Bassface we decided we needed to introduce this tech to the marketplace at a great price. We prototyped the amp with fixed filters and plug in terminals for power and speakers. It performed exceptionally and we put it into production. V1 – The V1 has fixed HPF/LPF filter switches and green plug in screw terminal block connectors. V2 – Realising we needed more flexibility and the screw terminal block connectors were even more fiddly, we swapped those for high quality screw terminals with increased gauge for power and ground. We then changed fixed the high and low pass filters for constantly variable HPF and LPF enabling the amp to be used without an external crossover for powering 2 way mid/high set up.
