Great Sound & Versatility
I’ve owned and used the Zoom P4 for over 6 months at the time of this review. It has held up nicely with no issues. I’m quite gentle with it, so I can’t speak to it’s durability.Pros:The audio quality is crystal clear.There is plenty of clean gain available.Each of the 4 mic inputs has +48 phantom power & mute option independently from one another (options that many interfaces and mixers do not have).Though I have not taken the P4 anywhere, it’s very lightweight and portable.It has options to use either batteries or 5V usb to power it. And when using batteries, it does power up for quite a while. Much longer than any recording session I’ve ever done.This option gives the ability to have battery backup for recordings.I like the ability to connect phone and computer to it and send and receive audio from both devices.The P4 is a great option to use as a phone audio interface. I’ve used it quite a bit just to record high quality audio to my phone. And it’s great to use for clean audio on phone calls as well.The mix- function works flawlessly. Making it super easy to use the P4 for call in conversations without feedback echo to the caller.It will record hours and hours of audio with even a small 8gb micro SD card installed.The P4 allows for dual (or triple) recording simultaneously.Recording on an installed SD card and a computer and/or phone (or any other USB or trs/trrs device).This makes this interface very versatile.It’s super easy to record or load pre-recorded sound to the sound pad.The sound pad has a volume control, just like the 4 mic gains and 4 headsets.Cons:16-bit/44.1 khz max recording/transmission resolution.Most USB interfaces & mixers have a minimum of 16-bit/48 khz resolution.I will say that in practice I cannot distinguish the difference in sound between the 2, however.Because of ultra compact size of this unit, there is no XLR or line output. Though you can use one of the headphone outputs if necessary, the sound quality will suffer a bit, as noise (hiss) will be introduced. The higher the volume, the more the noise.The P4’s all plastic exterior doesn’t instill confidence that it will withstand accidental abuse.

La verdad me sorprende lo pequeña y con que buena calidad graba.

I produce/edit podcasts for many clients. A couple of my clients use the Podtrack P4 and it has been pretty great for them. The Podtrack P4 is purpose-built for doing interviews, both in-person (with up to 4 mics) and via skype/zoom — or via phone. With a mixer or other audio interfaces recording high quality remote interviews can get really complicated. It just works out of the box with the P4. So my clients can just focus on doing the interview, instead of all the tech.The files they send me are good. Each person gets their own track so you can totally work it in post production. The preamps are good enough to use dynamic mics, like SM58s, etc….I bought mine for doing field interviews. And, actually, because of the ease of recording calls and skype etc…., I sometimes opt for using this over my much more expensive RME Babyface Pro interface for remote calls. And, the safety of recording to an external device is nice, don’t have to worry about a computer glitch losing the interview.You really can’t go wrong with this unit. I have a few nits, but they aren’t even worth mentioning, really. For the price you are paying, what this thing can do is nuts. It replaces so many pieces of kit and gets the job done.

chegou tudo certo, excelente!
