T+A has launched its latest preamplifier in the HV series, including a unique circuit board layout. 

The new T+A P 3100 HV is based on its predecessor, the P 3000 HV, the two units differ visually only in their type designation. However, under the aluminium cover, many unique technical innovations are concealed.

Most importantly, the entire preamplifier section has been improved by an entirely re-designed circuit board layout. The new digital power supply is stronger and better shielded and the already oversized toroidal transformer has been increased to 115 VA. 

In the previous model, the input and output stages were coupled to the relay volume control with high-quality capacitors. The very complex circuit board layout of the P 3100 HV eliminates the need for these coupling capacitors, refining the signal path between the input stage, volume control and output stage.  

In addition, the preamplifier board is voltage and temperature stable and all of the electronics are housed in a chassis and cover of uncompromising construction. 

Source devices connected deliver low-level signals to the preamplifier’s input section, and the unit’s task is to switch and amplify these signals, regulate their volume, process them where necessary and deliver them to the output sockets, ready for the power amplifiers. All this has to be accomplished without altering or falsifying the signals’ content.

The new P 3100 HV will be available from specialist audio retailers from May 2020 priced at £12,690.00 / €13,500 / $19,500.
