Description TECHNICAL SPECS
 
The PA 3000 HV is an audiophile High-End integrated amplifier packed full of unique, newly developed technological features. The measured values, speci-fication and power generated by this machine represent the limit of what is physically possible. The components and materials employed are of first-class quality, without compromise, and the workmanship of the case sets new standards which are unequalled even by much more expensive equipment. The case of the PA 3000 HV demonstrates the fundamental design principle of this range: the left and right channels are symmetrical, and of completely separate construction. This double-mono design, with discrete, independent circuit boards for the left and right channels, ensures outstanding channel separation, and prevents crosstalk.
The overall design of the T+A - HV (= High Voltage) series dictates that all the amplifier stages run at much higher operating voltages than usual; in the pre-amplifier this is 80 Volts, in the output stage 360 Volts. This means that - in a similar manner to valve-based amplifiers - the actual modulation of all stages is very small. Only a very small section (less than 20%) of the performance curve of the amplifier transistors is exploited, virtually eliminating the curved - i.e. non-linear - part of that curve. Further measures are also employed with the aim of linearising the voltage amplifier stages, such as cross-coupled differential amplifier cascodes and improved Hawksford cascodes with double J-FET control transistor. The result of the high operating voltages is extremely broad dynamic range combined with excellent linearity. We have developed this unique technology for use in all the machines in the series, since it provides enormous improvements in sound quality which naturally benefit the output stages of source devices such as the MP 3000 HV multi-source player as well as pre-amplifiers and power amplifiers.

The back panel of the case provides an impressive demonstration of the PA 3000 HV's uncompromisingly symmetrical construction: four symmetrical inputs are available (which can be wired asymmetrically if required), plus two further asymmetrical inputs and a recorder socket. As an option, input No. 4 can be configured in surround mode, allowing the output stages of the PA 3000 HV to be employed as the front channels of a surround decoder. One symmetrical and one asymmetrical pre-amplifier output are present. Two pairs of loudspeakers can be connected to the heavy-duty high-current loudspeaker terminals, which are made of solid pure brass, with all surfaces rhodium-plated. The socketry also includes H-Link (HV data bus), LAN socket, trigger input, RC-In for the E-2000 and an earth clamp. Since the momentary power drain can be very high, the machine is fitted with an oversized mains input socket. The case's de-coupled feet are height-adjustable, to ensure that the machine stands squarely even on an uneven surface. The PA 3000 HV is supplied complete with the F 3000 infra-red remote control handset.
