Bass Face DB2.2 v3
Περιγραφή
Version History
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. V3 - DB2.2 V3 uses a carefully redesigned board to reduce heat. V3 is easily distinguished with its 625mm length as compared to the previous generation which were 520mm long. Efficiency is up drastically along with a commensurate improvement in sound quality for very little sacrifice elsewhere - UPDATE - feedback indicates that the V3 sound quality is a little less "warm" than the older models. Some clients prefer this sound. On the whole V3 well received. V4 - V4 taking shape. We have received requests for the next iteration of the amplifier to use 0 GA power connections like the old V2 model
- further testing in Greece has revealed that contrary to our first thoughts the amplifier does produce more power with the terminals upgraded to 0 GA and so we will look to include this alteration in the future as long as we can keep the amplifier cool.
