An articulate headphone mix can make a tremendous difference to the outcome of a recording session. The 4-channel POWERPLAY PRO-XL HA4700 features superior performance, routing and mixing functions to accommodate the most discerning set of ears. Aux Input on each channel allows each performer to balance the Direct In signal with a second input – for a more customized mix. When a conditioned mix has to reach multiple listeners, the HA4700 delivers it in style.
