User manual ART 406

[. . . ] Headphone Mixing Made Simple The three basic requirements for professional headphone mixing 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. (4) A second stereo source may need to be connected and mixed with the stereo program perhaps added background tracks. (5) It may also be necessary to insert a specific audio source into a specific headphone channel possibly a vocalist wants to hear himself or herself alone. [. . . ] With the 406 in STEREO mode the PAN control regulates L/R headphone balance as usual. f) The INSERT jacks permit connecting a stereo source directly and exclusively to any headphone channel. Always plug a stereo (TRS) ¼" inch jack into these inputs so that sound can be present in both ears (these jacks are not affected by the Mono/Stereo button). When these jacks are in use, the MAIN and AUXILLIARY L and R inputs are disconnected. Only the INSERT signal goes to that corresponding OUT jack. g) Connect stereo headphones to the OUT jacks on the front panel and adjust the LEVEL controls as desired. DO NOT plug a mono jack into any OUT jack as this may damage the unit.
