T+A P 3000 HV Pre-Amplifier

  • The P 3000 HV is the audiophile High-End pre-amplifier of the series, and represents the universal control center for the individual new HV machines. It is equipped with unique, newly developed technologies and innovative circuit designs.

    Its measured results, specification and sound quality represent the limit of what is physically feasible. The components and materials employed are uniformly of top quality, without any hint of compromise, and the workmanship of the case sets standards which are unmatched even by much more expensive equipment.

    Technology

    In the ingenious overall circuit design of the HV (= High Voltage) series - developed in-house by T+A - all the amplifier stages operate at much higher operating voltages than usual: in the pre-amplifier the figure is up to 100 Volt, in the power amplifier up to 360 Volt. In a similar manner to valve amplifiers, the actual modulation of all the stages can be kept very low.

    Only a very small percentage (less than 20%) of the possible excursion of the amplifier transistors is used, thereby virtually eliminating the curvature (non-linearity) of that characteristic. Additional measures for improving the linear nature of the voltage amplifier stages are also employed, such as cross-coupled differential amplifier cascodes or improved Hawksford cascodes with double J-FET control transistors.

    In addition to outstanding linearity, the high operating voltages employed offer the advantage of extremely wide dynamic range. We have developed this unique technology for use in all the HV-series machines, since the tremendous sonic improvements which it makes possible can be exploited in the output stages of source devices such as the MP 3000 HV multi-source player as well as in pre-amplifiers and power amplifiers.

    The connector section on the back panel provides impressive evidence of the P 3000 HV's uncompromising design and symmetrical double-mono construction. Both balanced and unbalanced sockets are available as outputs. There are four balanced inputs which alternatively can be configured as unbalanced types, plus two further unbalanced inputs and a recorder input. Input No. 4 can be operated in surround (pass-through) mode in order to use the power amplifier for the front channels of a surround decoder.

    The analog and digital mains power supplies are completely separate from each other, and even feature separate mains sockets! HV-Link (HV data bus), LAN socket, trigger input, RC-in for E-2000 and an ground terminal are also present.

    The P 3000 HV is equipped with a high quality headphone amplifier with dual current capability and is supplied complete with the F 3001 infrared remote control unit.

    In practical daily use problems often arise with room acoustics or loudspeaker positioning. To alleviate this difficulty we have developed an analogue signal processor module which not only offers tone and loudness functions operating separately for each channel, but also features three narrow-band parametric equalizers which are capable of effectively damping room resonances in the range from 20 Hz to 500 Hz.

    The net result is that superb sound quality can be obtained even in difficult rooms. As you would expect, these functions can also be completely by-passed by means of relays.

    Upon request the P 3000 HV can be fitted with High-End phono pre-amplifiers, which possess different circuit topologies for MM or MC pick-up systems.
