The Zoom PodTrak P4 is a portable audio recorder designed for podcasting enthusiasts. There can be up to four mics and four headsets connected, so everyone joining your podcast will have a mic and headphones and their own volume dial. Plug your smartphone directly into the recorder for distortion-free call-ins for your remote guests. You can bring in remote guests and callers wirelessly with the Zoom BTA-2 Bluetooth receiver. There are four easily accessible sound pads that are perfect for elevating your production quality with music, jingles, ads, sound effects, and pre-recorded interviews.
