This quick guide provides essential information for setting up and using the device, along with details on its connections, features, and related products.

Function Description:

The YELLOW SINGLE serves as a single-channel acoustic preamp, offering pristine signal conditioning for a wide range of instruments and microphones. Its primary function is to provide clean gain, tone shaping, and output options for live performance, studio recording, or practice. It features dedicated inputs for both microphones (XLR) and instruments (1/4" jack), allowing users to connect various sound sources. The preamp includes phantom power (+48V) and +10V power options, making it compatible with condenser microphones, DYN P48 contact microphones, STAT pickups, and other electrostatic microphones. The tone shaping capabilities are provided by a comprehensive EQ section, including LOW CUT, LOW, LOW MID, HIGH MID, and HIGH controls, along with a WARM/Ø switch for subtle tonal adjustments. The device also incorporates a MUTE function for silent signal interruption and a MASTER VOLUME control for overall output level management. For external effects integration, the YELLOW SINGLE offers SEND and RETURN jacks, allowing users to incorporate their favorite effects pedals or rack units into the signal chain. Multiple output options, including balanced and unbalanced master outputs, and a balanced DI output, ensure compatibility with various amplification systems, mixers, and recording interfaces.
