DB4.4 Class A/B 4/3/2 Channel Bridgeable Stereo 12v Power Amplifier 840w Verified RMS Power Output

World RRP: £198.95

Category: AMPLIFIERS

Product code: DB4.4

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.

Technical Highlights

  • High Fidelity Class A/B Topology
  • Band Pass Crossover
  • Variable Bass Boost
  • Soft Turn On/Off
  • 2 Ohm Stable Stereo / 4 Ohm Bridged
  • Variable High Pass Crossover
  • Variable Low Pass Crossover
  • Up To 6V Ready Pre Amp Input Stage

Version History

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 at this stage.
