The new Digital Technology Series
amplifiers with class D final stage are available in four
models with a choice of powers and numbers of channels. The XTDT3200
models have two channels and supply power up to 1600 W
and 1900 W
, respectively, per channel on 4Ω. The XTDT4800F
models, on the other hand, have four channels of 1200 W
and of 1500 W
, respectively, again on 4Ω. All the amplifiers in the XTDT range have been entirely designed in switching technology
(both the section of the feeding unit and the power stage) so as to obtain greater power and yield, in a lightweight element, which is inconceivable for traditional configurations.
The power supply also has the very useful active PFC (Power Factor Correction
), which lowers the angle of phase shift φ between the power received from the network - called apparent
- and the active one which represents the effective work, thus reducing the component of reactive power that springs from the connection of an inductive load to an AC power supply line. In practical terms, the power consumption is significantly reduced and, in addition, the device performs automatic adaptation of the mains tension of the geographic area of use. These characteristics make the range particularly interesting for the typical demands in the professional audio sector: power, light weights and high performance (therefore low consumption).
