Lab12 PRE1 Tube Preamplifier


Class A Tube Preamplifier

PRE1 aims at exactly the same target as all Lab12's products do, to achieve a warm, musical and most of all realistic sound that remains enjoyable even after many hours of listening. They achieved to give PRE1 a high class performance, much higher than its price range. It is a great choice to be combined with a solid state or tube power amplifier. In both ways PRE1 will give the known warm, friendly and analytical sound of LAB12.

Internally they use a matched pair of E88CC tubes in a special configuration and a solid state power supply with 4 regulation stages offering smart filtering and more than enough capacity. Dual mono philosophy and Fine Symmetry® exist in every stage of the internal circuit and of course we use SRSG® topology in this gear too. Special selected parts like MKP audio grade capacitors and resistors with 0.1% accuracy also contribute the production of the final detailed sound and the wider resolution.

PRE1 offers five analog inputs and two preamplifier outputs, so you can easily drive a bi-amping system or a power amplifier and active subwoofer(s) with no problem. Input selection can be performed by the on face rotary switch or by remote control.
