An introduction to the ADDAC219IN Stereo > Dual Mono. The ADDAC219IN Stereo > Dual Mono is an interface module that separates external line-level stereo signals into individual left and right mono outputs. It accepts a 3.5mm stereo TRS jack input, internally splits the signal into left and right mono, and outputs each through independent 3.5mm mono output jacks. It also boosts line-level signals to Eurorack level. With two conversion sections, this module serves as a bridge between external gear and your Eurorack system.

An introduction to the ADDAC219OUT Dual Mono > Stereo. The ADDAC219OUT Dual Mono > Stereo is a passive 3HP module that provides a simple way to send signals from your Eurorack system to external stereo gear. It combines two mono inputs (left/right) into a single TRS stereo output, attenuates the modular synth level down to line level, and outputs through a 3.5mm TRS stereo jack. With three independent sections, it can send multiple outputs to external gear at once.

An introduction to the AI Synthesis AI026 Line I/O Interface. The AI026 Eurorack Line Interface converts between line-level signals (approximately +/-2V) and the signal levels commonly used by Eurorack modules (approximately +/-5V). This allows you to boost low-voltage line-level signals to standard modular synth levels, or perform the reverse.
