Preset Manager

The 44TDAP Series amplifier preset manager focusing to give a more speaker-based approach to controlling, designing and recalling speaker configurations.
The Device Preset module, provides access to a full device preset of the device. The Speaker config module gives access to only one output channel block.

FIR Filtering

The advantages of FIR filtering include more arbitrary and fine control of a filter’s magnitude and phase characteristics, independent control of magnitude, very long minimum-phase FIR based system EQ, horn correction filtering, independent control of magnitude and phase, and mixed & maximum-phase characteristics.

The 44TDAP DSP amplifier systems integrate light-weight power supplies, high power sonically transparent class-D amplifiers, complete system monitoring and a fully featured ETHERNET network controlled 32 bit / 48kHz DSP processing platform,handled by the front panel dual Rj45 connectors, as standard.

44TDAP Series have been engineered for mid sized venues, rental and touring applications, adopting circuit architecture of multi-loop control technology, bearing-up constant resistance output and developed for low-impedance and high-current, as a result we obtain a power amplifier with a 90% efficiency and an incomparable stability.

All 44TDAP Series amplifiers come with built-in active Power Factor Correction and soft switching technology. It can ensures that a predominantly resistive load is presented to mains thus minimizing current distortion and voltage/current displacement. This leads to improved performance of the amplifier at high levels of output and avoids mains-voltage collapses, typical of standard and switching power supplies. Another great advantage of this

technology is that its performance is, to a large extent, independent of mains voltage. The rated output power does not vary with load/line conditions.

The advanced 48kHz DSP is fully integrated into the product and provides an amount of useful features. Its powerful Limiter suite provides Peak and RMS limiting, as well as multi-band limiting for passive 2-way enclosures. Many convenient features are provided as Gain, delay, EQ and a powerful FIR filtering with 512 taps, bringing linear phase response to the Tecnare presets.
