The ART Model 406 Six Channel Headphone Amplifier addresses the basic requirements for professional headphone mixing. It is a great processor for professional, project and home studio applications. Model 406 has an output and level control for each set of headphones, and a stereo input for connecting the program source.
The three basic requirements for professional headphone mixing of Model 406  are; (1) an output for each set of headphones, (2) a level control for each set of headphones, and (3) a stereo input for connecting the program source (mixer, CD player, tape deck. etc.). But there may beotherrequirements. (4) A second stereo source may need to be connected and mixed with the stereo program perhaps added background tracks. (5) It may also benecessary to insert a specific audio source into a specific headphone channel possibly a vocalist wants to hear himself or herself alone. (6) You may find it necessary to connect a number of mono sources rather than one or two stereo sources and have some degree of control over their relative volumes perhaps the recordist or director needs to address everyone. The trick is to make this headphone mixer compact and simple to use.
