The uttermost quality of a preamplifier is its transparency. The source is selected and the volume is applied, however the original audio characteristics and signal dynamics are fully retained. The L1, a dual monaural analog line level preamplifier, was developed using this approach. It is a pure class A, ultra low noise, high bandwidth, fully balanced transistor based design. It provides the shortest path between input and output, maintaining the highest speed, transparency and musicality, allowing the L1 to become a truly exceptional preamplifier.
Three L1 configurations are available:
For each channel two R-2R ladder network in balanced mode control the volume. Tight tolerances high-grade metal film resistors as well as fast switching, distortion-free analog switches are used to adjust precisely the listening level. Each ladder has the following features:
Each channel is physically mounted on its own board to ensure the best immunity against crosstalk, and has the following features:
