KLANG:vier is the leaner version of KLANG:fabrik. It offers 5 individual immersive mixes of 24 input channels and 4 studio-grade headphone outputs.


KLANG:vier supports individual immersive in-ear mixes for 5 musicians. You can plug in your 1/4” headphone jacks during rehearsal or use the DB-25 break-out interfaces e.g. for your radio transmitters on stage. Musicians benefit from the high-end headphone amps if they use a hardwired in-ear setup.
