    The DB4.1 DB2.1 and the DB1.1 were the original amps in the DB series. The 4 channel is a strong, reliable amp with modest sound quality at a very affordable price. V1 - The first version had great power, good reliability and useful feature set. V2 - The V2 was the same as the V1 but with manufacture moved to a new location. V3 - Upgrade power supply for higher power output and better sound quality, as well as some visual changes and changing the terminals to a better quality design. V4 - Bassface 2016 styling and some slight modifications to the crossover. V5 - Assembiles from November 2016. Following analysis in detail the amplifier has undergone improvements. Transformers and inductors are affixed to the PCB using improved adhesive. New output transistors for significant extra power. Reverse polarity connection protection upgraded to improve chances of withstanding a reverse connection. The circuit board has been lifted in the case to align the controls better and a rounded mounting foot has been introduced also to remove sharp edges. Crossover distortion has been reduced due to detail changes on the board. Felt strips have been added under the baseplate to ensure no rattles.
