Compact, affordable, and packed with features, the PodTrak P4 makes it easy to capture professional audio files no matter where you save your podcasts. The P4's mic inputs feature professional-grade Zoom preamps. Offering up to 70dB of gain, the P4 can be used with the most demanding microphones. With 4 independent headphone outputs, each with its own volume control, everyone can hear it all. You are not always in the same place as your guests. This is why the P4 facilitates the integration of remote interviews. Just connect your phone to the P4 with a TRRS cable. Or connect your computer via USB, and use your favorite conferencing software. Thanks to the P4's built-in one-channel submix function, annoying echo and feedback are automatically eliminated. The P4's customizable Sound Pads can instantly trigger pre-recorded music, commercials, jingles and even interviews. Easily load your own sounds or choose from 11 presets. The P4 runs for up to 4 hours on 2 AA batteries, or you can also use a USB battery for longer recording time.
