The Zoom LiveTrak L-8 is a compact, 8-channel digital mixer and recorder. It has been designed with the creative podcaster in mind. You can easily play intros, outros, jingles, ads, and sound effects using 6-easily assignable Sound Pads. You can effortlessly take calls or conduct remote interviews by connecting your phone via the provided TRRS cable. The mixer will eliminate echo and feedback to and from the caller by using the Mix-Minus function. Record separate tracks directly to an SD card to edit them later. The mixer can be powered up by AA batteries, a USB charger, or the included power adapter.
