T+A PS3000HV Power Supply


The PS 3000 HV is a supplementary mains unit which was developed specifically for the A 3000 HV power amplifier and the PA 3100 HV integrated amplifier. Both deliver more than 500 Watts of power into 4 Ohms, and at such a high level of sound quality and performance that simply increasing the output power – and with it the voltage – produces no significant improvement in sound. Our research and development work in high-performance amplifiers – including the M10 and S10 – and the development of the HV design philosophy which flowed from this work, have shown clearly and unambiguously that the stability of the voltage and current supplied by a mains unit is of major and even crucial importance to the sound quality of an power amplifiers. From this we have drawn the only rational conclusion, and developed a supplementary external power supply.


The principle is ingenious, and functions in the following way: if the PS 3000 HV is connected to the A 3000 HV or PA 3100 HV using the special PowerLink with M 23 high-current connectors, the A 3000 HV’s or PA 3100 HV internal power supply is used to supply energy to the input stages and the high-voltage amplifier; much lower power is required for this part of the system, and as a direct result the interference generated in the A 3000 HV or PA 3100 HV itself is much lower. The external PS 3000 HV supplies the energy for the output stages, i.e. it is responsible for the high currents required by the power output stages. With an output of 1200 VA the PS 3000 HV is substantially more powerful than the mains unit of the A 3000 HV or PA 3100 HV itself, and can also call upon twice the reservoir capacity. The net result is a substantial improvement in the current delivery capacity and stability of the system as a whole.
