Height | 133 mm |
Width | 440 mm |
Depth | 440 mm |
Weight | 20 kg |
Modularity:
Three L1 configurations are available:
Volume control:
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:
Analog Signal Path:
Each channel is physically mounted on its own board to ensure the best immunity against crosstalk, and has the following features:

L1 Enclosure
| L1 enclosure The addition of a second L1 enclosure transforms the L1 into a True Monaural preamplification system. The power supplies inside each enclosure are devoted to a single channel, further enhancing the noise performances of the system. The units are |
PRE | Monaural analog preamplifier board preamplifier board. This turns the L1 into a True Monaural Extended system, providing the preamplifi er with twice as many inputs, ideal for larger systems. |
X1
| X1 external power supply Improves the overall L1 performances by adding an external power supply unit. Same unit dimensions as the L1 |
