Schertler Yellow UNO

YELLOW UNO is a sophisticated single-channel Class-A preamp. It has been specially developed to offer musicians and sound engineers a high-quality yet straightforward solution for a range of performing and recording applications (preamp, buffer, D.I. box, etc.). The portable preamp has one dedicated input channel that accepts a range of microphones, pickups and instruments. This makes it ideal for solo performers or individual ensemble members. No matter if you’re a guitarist, violin player or other musician, the YELLOW UNO can be your perfect ally.

YELLOW UNO’s simple yet efficient controls include a VOLUME, an adjustable WARM filter, and a MUTE function. It is possible to activate the 10V tension on the INPUT jack to feed electret microphones (such as the SCHERTLER STAT) or set the OUTPUT as balanced or unbalanced.

YELLOW UNO can either work with a 9V or 12V power supply (not included) or with a 9V battery. A full set of LED indicators will guide you through your preamps functions and their status.

YELLOW UNO is available as a stand-alone preamp and is also included in all STAT-UNO packages.
