Product description

Now shipping Version 4 of this product - DB1.1 is technologically very far advanced now. Newly updated for 2017 and almost five years of development down the line the latest DB1.1 is taken into the digital age with a new class-D board. This means its now properly 1 Ohm stable. The amplifier ships with a remote level controller to allow on the fly fine tuning of settings. An adjustable sub-sonic filter lets you keep the power going to where you want it and a bass boost can help maximize output from your subwoofer set up. We included two output terminal pairs to make it easier for you to connect two subwoofers or dual voice coil subwoofers to the one amplifier. Just like its DB family members, the DB1.1 is built around a striking and beautiful heat-sink. It's not just there to look good but also to optimise passive air convection over the amplifier which will keep the amp running cooler for longer.

Prototype – The original DB1.1 dates all the way back to the beginning for the Bassface story. The monoblock of the original line up for 3 amplifiers. V1 – The V1 hit markets in 2011. This class A/B mono had a modest output but had a few issues which were later revised in V2. V2 – This version built on the V1 but came from an entirely new factory. With slightly increased output and a more robust power supply. V3 – The V3 saw the DB1.1 gain higher quality output devices and better thermal protection. This meant less failures when people were using them incorrectly (which happened a LOT) V4 – Looking back through the failure reports form the previous versions it was clear that users still did not understand the 1 output over 2 sets of terminals and 80% of the failures were due to the amps being run at too low impedance with people still thinking they were stereo amps. So, in light of that, we decided we were going to make them digital to circumvent this problem. The V4 puts out almost identical power at 2Ohm but now can output more than the original DB1.1 AND run at 1Ohm…. AND can be linked and give double output into 2Ohm! As well adding higher quality terminals and potentiometers. Yet still retaining that high performance to price ratio that we are so proud of! Also the V4 features the new 2016 logo panel on top! Quoted theoretical figures revised after further testing. V4 can be identified also by gold plated terminals and RCA connectors.
