Functional The pMix personal audio mixer is the unique and versatile audio mixer designed specifically for all personal audio devices such as ipod mp3 player satellite radio CD DVD and computers. Simply connect audio devices and amplified speakers to the pMix for total control of all sound sources through a single speaker system. This eliminates the expensive cost of having to purchase multiple speakers and the clutter they create! Practical Remember the old days when a radio had a simple volume control knob. If the radio was too loud you would just have to turn the knob counter-clockwise and the sound would instantly lower. With today s audio devices volume levels are controlled by elaborate electronic buttons or menus that are not always easy to access. The pMix control knobs work just like that vintage radio knob allowing instant sound adjustment of up to three audio devices at your fingertips.
