Product code: BLACKDB4.1

Product description

The BLACKDB4.1 features a discrete class D circuit design. Discrete circuitry design is different from IR NXP IC design in the way that we can select parts meticulously to best match each other to achieve better S/N ratio and THD figure. Since all the components are not integrated like an IC, this allows better heat dissipation of the components, which means it is able to achieve higher audio frequencies with less distortion. Our class D amps sound better and smoother than standard IC solution class D full range amps. You get full frequency response past 22Khz distortion free – An issue inherent in even quite advanced class D full range amplifier designs. The feature we are most proud of is the highly advanced and very tuneable crossover section – featuring HPF, LPF and BPF available for each channel, plus a x10 multiplier switch and a clone function. This enables you to run a plethora of set ups without external processing. From a simple stereo front and subwoofer bridged, to a stereo 2 way active set up running 2 tweeters from 5khz up and 2 8” mids on a BPF from 250hz to 5khz. It is very flexible and gives you a very detailed and tailorable output control functionality. These are thoroughbred sound quality power amplifiers for the discerning individual who can appreciate a very high quality audio experience. Coupled with the right speakers, these are a genuine pleasure to listen to, delivering a level of detail that is quite simply stunning.

Prototype – Like the BLACK series monoblock, we wanted a very high quality product to fit in line with our top spec BLACK series. We opted for a digital 4 channel, which with recent advances in technology has meant high quality sound is easily achievable. The BLACKDB4.1 is no exception and the prototype was a perfect balance between power and warmth. We modified the crossover a little from the prototype and put them into production. V1 – The V1 was delivered to markets in late 2015 and has so far proven to be both reliable and sound great with no bad feedback coming from customers and professionals.
