KLANG:vier supports individual 3D in-ear mixes for 4 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 can also benefit from the high-end headphone amps if they use a hardwired in-ear setup.
Easily extend your KLANG:fabrik system for more musicians and control all KLANG:fabrik and KLANG:vier mixes within the KLANG:app.
