The PA 3100 HV is a further development of the PA 3000 HV, and most of its sub-assemblies are identical. The immediately obvious difference is the pair of VU meters in the front panel, which display the power generated per channel in logarithmic form in Watts into 4 Ohms. A revision of the pre-amplifier section (D.C. coupling) has brought an additional improvement in sound quality.
A further development is the redesigned analogue mains section and voltage power supply, which is similar to that of the A 3000 HV. This makes it possible to connect the supplementary PS 3000 HV mains section in order to gain a further increase in stability and performance of the power supply system as a whole. The additional unit provides an extra 1800 Watt of supply power, enabling the system to control even the most difficult loudspeakers without effort, so that they can unfold the best possible sound quality.

As an option the PA 3000 HV and PA 3100 HV can also be fitted with High-End phono pre-amplifier modules which feature different circuit topologies to suit MM or MC systems. It is also possible to install the analogue signal processor module which has been developed for the P 3000 HV to provide channel-separate tone and loudness functions.
The all-metal F3001 infra-red remote control handset is supplied as standard.
