T+A Elektroakustik P 3100 HV Preamplifier

T+A Elektroakustik P 3100 HV Preamplifier A fully dual mono design with 4 x XLR and 6 x RCA (one optional phono) inputs, and a headphone out. T+A approaches preamps as being the most important components of a high-end system. They are of discrete, fully symmetrical construction, and every single component is the very finest available. This is all housed in T+A's famously uncompromising HV chassis. A new, very complex circuit in the P 3100 HV compensates for the temperature coefficients of the transistors. Operating points can be set exactly, which means that the preamplifier stages have a pure DC coupling. There are no longer coupling capacitors in the signal path between the input stage, volume control and output stage. The digital power supply is ample and heavily shielded. The analog toroidal transformer is enormous, and an amazing 115 VA. HV Means High Voltage The T+A HV series are so named because they run at an unusually high voltage internally. In the preamp, it's 100 V, and in
