The PA 2500 R amplifier is the big brother of the PA 2000 R. It is also built on the "dual mono" principle, but it has a more powerful power supply (the amplifier outputs 280 watts at 4 ohms). The body height has been doubled. The PA 2500 R has rich XLR switching. Its discrete sections, by analogy with the HV (High Voltage) reference series, operate at high voltage, providing an incredibly wide dynamic and frequency range: from 0.3 Hz to 300 kHz.
The integrated PA 3100 HV amplifier continues the concept of the PA 3000 HV model and partially inherited its design. It is different in appearance, there are now arrow VU-indicators on the front panel. The preamp circuit has been improved. It is possible to connect an external PS 3000 HV power supply. As with all High Voltage devices, the PA 3100 HV amplification stages are built on differential microcircuits made of discrete elements.
The heart of T+A Symphonia is its proprietary power amplifiers using Purifi Eigentakt technology. According to T+A, this platform, developed by the Danish technology company, is nothing less than one of the best concepts of class D amplifiers, as it overcomes the limitations of other class D amplifiers - characterized by an extremely low distortion factor and minimal intermodulation distortion regardless of the power.
