So what is d-tech

 D-TECH is a state of the art technology  that gets more power out of an amplifier with less wasted power than was ever before possible.  D-TECH is a type of digital switch-mode power amplification design that is highly advanced and delivers a tremendous amount of power and very clear sound in a very small size.

Features of the new digital power amplifier from tafn

  D-TECH uses a special type of switch-mode power supply technology, which ensures that in the event of fluctuations in mains power, the output remains stable because of D-TECH’s fast-feedback system.  As added protection, the power amplifier can withstand any sudden cut, drop or surge in mains power. The soft-start feature ensues that after power returns to operating levels, sound increases gradually rather than all at once, which safeguards the power amplifier and speakers.

 Thanks to its extremely low output impedence, D-TECH has a very high damping factor, which gives it more control over the cone movement of the speaker, and therefore a realistic, rock-solid bass sound. Even when the power amplifier clips, the damping factor will remain high, so that the sound coming out of the speakers is still as solid.

   In the event of overloading or a short circuit, D-TECH’s automatic gain control (AGC) device limits output current automatically.  This makes the amplifier very reliable, and extremely unlikely to sustain damage. The AGC monitors the output current constantly, and if the current exceeds its pre-set level, it will restrict the signal to keep the current within those limits, regardless of how hard the short circuit or extent of overloading.

  The D-TECH power amplifier uses switch-mode technology, which generates minimal heat. It also re-uses energy returned from the speaker rather than dissipating it as heat or forcing the amp into premature current limiting. By generating less heat, the D-TECH digital amplifier also dispenses with the need for large heat sinks, making the amplifier smaller and lighter.

GRAPH: Comparison of heat dissipation loss between different technologies

Class-AB  50% Power loss in heat

Class-H  30% Power loss in heat

Class-TD  10-15% Power loss in heat

D-TECH  5% Power loss in heat

The D-TECH power amplifier loses only 5% of energy to heat, compared to up to 50% for a conventional (Class AB) power amplifier. The Class-H amplifier loses about 30%, and Class-TD loses 10-15%.

  With less heat loss, D-TECH’s digital amplifiers need nearly half the amount of power to run compared with conventional Class-AB power amplifiers, which saves on electrical installation costs and power bills.

How does D-TECH do it? We combine the benefits of an advanced digital power amplifier and a specially designed digital switch-mode power supply, to make the amplifier smaller, lighter, and more efficient.

  TAFN makes digital amplifiers in two series: D-TECH SERIES, and I-POWER SERIES. Both series use core D-TECH technology.

   The D-TECH SERIES is a digital power amplifier which is only one unit high but delivers unmatched power for its size. It uses a state of the art technology to achieve unparalleled power and very clear sound in a compact design. The D-TECH SERIES can deliver several times more power than other amplifiers of the same size and weight. Read more about it here.

   The I-POWER SERIES is a digital amplifier which is two units high but again delivers unmatched power for its size. The I-POWER SERIES can take up to two ohms per channel while still maintaining a tight sound. Its special circuitry is designed for low impedence which can handle high currents effortlessly.  This allows it to take up to four speakers per channel while avoiding problems common to conventional designs such as overheating and loss of sound quality.
