Podcasting Like a Pro Has Never Been Easier. Or Better.
The PodTrak P4next features 4 XLR inputs with high-gain preamps and next-gen features like AI noise reduction, tone shaping, and voice compression – making broadcast quality podcasting easier than ever.

AI Noise Reduction
Don’t let hums, buzzes, and street noise ruin your conversation. Let AI noise reduction learn and remove unwanted noise, keeping your voice clear, natural, and detailed.

Your Voice, But Better
The Tone feature instantly adds polish to your voice with EQ and de-essing, reducing harshness and adding warmth for a clear, professional podcast sound.

Broadcast Ready
The built-in compressor keeps your podcast sounding crisp and balanced, smoothing out sudden shouts, laughter, and whispers.

Built for Every Microphone
Some microphones need more power. The P4next’s four XLR inputs provide up to +70dB of gain, allowing you to use even the most demanding podcast mics.
48v Phantom Power available on all channels

Get the Show on the Road
The P4next’s compact design and versatile power options give you more than portability – it gives you the freedom to record your podcast anywhere. Run it on two AA batteries or via USB from a mobile battery, bus power, or AC adapter.
12W or above

Guests Always Welcome
Bring in two remote guests via USB, Bluetooth, or the TRRS input. Use the remaining 3 mic inputs for a 5-person podcast. The built-in mix-minus removes echo and feedback automatically.
