T+A PA 3100 HV Integrated Amplifier

19000,00 

The T+A PA-3100 HV is a further development of the PA-3000 HV and is identical in most modules. The immediately visible difference is two VU meters in the front, which display the output power per channel logarithmically in watts at 4 ohms. In addition, a new concept for the analogue converter part and the voltage supply was developed similar to the A-3000 HV, which allows the PS-3000 HV to be connected and the stability and performance of the entire voltage supply to be increased again.

Description

Overview

On request, the T+A PA 3000 HV and the T+A PA 3100 HV can also be equipped with high-end phono preamplifier modules, which have different circuit stopologies for MM or MC systems. It is also possible to install the analogue signal processor module from the T+A P 3000 HV for channel-separated sound control and loudness functions. The all-metal infrared remote control F3001 is supplied.

Technology

As in the T+A P 3000 HV, the circuit topology of the amplifiers is based on a cascode differential amplifier with hand-selected audio J-FET transistors and completely discretely constructed stages without an operational amplifier. This circuit concept and the quality of the components means that virtually no over-all-counter-coupling is necessary. Thanks to its high operating voltage, the HV technology also allows extremely high linearity as well as an extremely high dynamic range. Signals up to 60 Vpp can be processed undisturbed.

In the T+A HV series, switching and switching functions in the signal range of gas-tight encapsulated gold contact relays are adopted which, even after many years of operation, do not have any contact problems due to corrosion, dust, etc. and no ageing.

In the preamplifier, bi-stable relays are used in which no permanent coil current flows anymore and thus also no inductive impairment of the audio signals can take place. Due to the integration of the relays directly into the circuit, the signal paths are optimally short and there are no cable paths, such as conventional volume potentiometers. The volume control is also built with discrete precision resistors and gold contact relays, so there is absolutely accurate channel balance, no noise and no distortion.

The entire control electronics are deeply recessed and shielded in the 40 mm thick and fully milled front panel, on the front of which is the luminous and dimmable display (VFD) made of glass with wear-free sensor buttons.

About T+A
For Generations We are a family company, managed by its proprietors. If we pose the question: why is T+A equipment so special? Then we find the answer in the following situation: we grant ourselves the freedom to implement our convictions; to focus on decades, rather than just the next quarter. It is precisely this independence of action which enables us to accomplish long-term goals. For example, we took three years to develop the first device in our HV Series, and it was perfect. Our company founder loves music and technology, believes in science and the laws of physics, and always aimed to push those limits as far as possible; every single T+A device incorporates those convictions. These values will continue to be our companions for generations to come. At the same time the principles of our family enterprise are also reflected in our support for the coming generation.
