Schertler Yellow UNO Preamp
YELLOW UNO is a sophisticated single-channel Class-A preamp 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.). This portable preamp has one dedicated input channel that accepts a range of microphones, pickups and instruments. YELLOW UNO pairs perfectly with Schertler's STAT-series pickups and makes it ideal for solo performers or individual ensemble members.
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.
