Stereo headphone/line output for Eurorack

4 HP Eurorack module

Listen Up is a compact 4HP headphone and line output module from 4ms. It converts Eurorack-level signals to headphone or line-level output via four 1/4" TRS jacks. The Left In jack is normalled to the Right In, so a single stereo or mono source patched into Left In automatically feeds both channels. The module provides clean, low-impedance output suitable for headphones or connecting to external mixers and audio interfaces.
