Product description

Now shipping Version 2 of this product - DB2.2 is a power house 2 channel amplifier. Boasting over 500W RMS per channel into 4Ohms. This amp is quite a leap from the DB2.1 with totally different heatsink body and a much larger form factor. The DB2.2 has been designed to fulfil the needs of our competition customers. The amp has been built with SQ in mind over SPL. Although it develops extremely high power output, the electronics are all carefully selected and matched to give you an impressive 0.04% THD (Distortion) at full power on 4Ohm. So even at extreme output levels, the sound will be very clear and tonally balanced. We included steep 24db/oct LPF as well as HPF as the amp is so big it lends itself well to powering SQ subwoofer set ups, where the big bad digital amps fall short of giving that warmth you get from Class A/B. On that note, we also included a remote level control, as you would expect to get with a decent subwoofer amplifier. The internal power supply is overbuilt to enable the amp to work very hard without fatiguing other components and not drop below its rated output. When using this amplifier at maximum performance be sure to grant adequate cooling - this monster draws enormous current and produces enormous power!

Prototype – Developed specifically to compete in the Italian marketplace as a high output, high quality class A/B amp to power very big midbass installs. The DB2.2 prototype ticked all the boxes upon arrival. So we put into production the V1. V1 – Arriving to markets in 2014 the V1 performed well. V2 – The V2 addressed an issue we were seeing with these getting very hot when driven hard by adding a good size fan on the underside to force cooling. As well as the fan we introduced improved crossover functionality for users who want to use them without extrnal processing. V2.1 - On sale from Q1 2017 V2.1 features improved capacitor selection. This is a marginal improvement only. There are no external features to distinguish V2.1 units from V2.0 units and there was some stock crossover, with the entire batch of 2.1 units selling out by the end of Q2 2017. We resumed sending V2 units at this time until the V3 arrives or we run out. V3 - Production agreed of DB2.2 V3 at same price point and same power but using carefully redesigned board with more efficient output stage to reduce heat. ETA to market Q3 2017.
