English: LUCE (“light” in Italian) is a compact, studio-quality tube DI (Direct Injection) and unity-gain preamplifier designed to convert unbalanced instrument signals into a balanced, low-impedance output with a warm, natural tube character. It features a transformer-coupled balanced XLR DI out, a tube-driven ¼″ output, active summing allowing two instruments, and a PAD switch for high-output sources, all built around a high-quality ECC88/6922 tube and an OEP/Carnhill audio transformer.
