Product description

With the DB4.1 as a smaller option and the BLACKDB4.1 as a Class D alternative the DB4.4 is our high power 4 channel amplifier in traditional Class AB format. The unit is cased in the same heatsink design as the DB2.2, DB1.3 and DB1.4 and has a full complement of controls including a versatile band pass filter with 300Hz low pass reach (allowing, for example, an active midbass setup etc) on both sets of channels. With awesome output power, smooth, musical sound and unmatched versatility the DB4.4 is a terrific complement to the biggest audio systems.

V1- Delivered to market Q3 2017 the DB4.4 is an all new design, drawing from our experience with the DB2.2 and DB1.3. The factory is very experienced at producing high quality products and the DB4.4 will deliver high power and repeatable performance consistently from its professional grade board and architecture. V2 - A revised circuit board is already on the drawing table to make small but incremental improvements in efficiency. We will also change the power connections to 0 AWG (aesthetic reasons only) and the colour of the hardware will be silver not gold. This is a drawing only and will not be anywhere near production until well into 2018.
