4ms Listen IO Modular Signal Converter

Convert Signal to and from Your Modular Setup for Infinite Integration Possibilities with the 4MS Listen IO Modular Signal Converter

The Listen IO is a compact Eurorack module that allows seamless conversion between modular signal levels and standard line levels. The top section amplifies incoming external signalslike synths, groove boxes, computers, or micsup to modular levels with up to 30x gain (+30dB). The bottom section does the reverse, attenuating modular signals down to line or headphone levels. Use it to connect your Eurorack setup to mixers, recorders, or speakers. Dual headphone outputs let you and a friend monitor simultaneously in stereo.

Each section features stereo (or dual mono) I/O with LED level meters for clear visual feedback on output levels and clipping.

• Line-to-modular and modular-to-line/headphone level conversion
• Compatible with guitars, synths, mics, pedals, groove boxes, and more
• Stereo or dual mono operation
• LED meters display signal level and clipping
• Wide gain range via front-panel control
