The Phenyx Pro PTX-15 is a 4-channel mixer, meaning that you can record or broadcast with up to four people. Let’s take a closer look at what each channel includes:

  • XLR input & line input: to connect your microphones/instruments. Only one can be used at a time per channel.
  • Gain control: to adjust the input signal level.
  • 3 EQ band: adjust the lows, mids, and highs of each channel separately.
  • EFX send: adjust the amount of effects you send to each individual channel.
  • Pan/balance: choose whether to send the signal through the left, the right, or equal amounts to both for a balanced sound.
  • Fader: control the sound volume from the mic or other inputs for that specific channel.
  • Solo (PFL switch): press this button to monitor the sound before it goes through the output.

Having this much control over each channel is great for a product at this price point.

Mixer output section

We’re now going to focus on the mixer output section at the top of the Phenyx Pro PTX-15:

  • Main output (left/right): the output mix to the main amplifier
  • Aux send/return jack: send mix out to outboard gear and have it come back in, or use an auxiliary output to send it to a computer
  • Rec out left/right: if you want to record your audio on another device using a RCA cable.
  • USB player: plug in a USB stick to use playback for WAV/WMA/MP3 files with built-in controls to play/pause/switch between modes.
  • Bluetooth: connect your device (smartphone, tablet…) wirelessly. Simply press “mode” on the USB player until “Blue” appears.

The various outputs allow for a number of different configurations depending on what you’re planning on using it for. The USB player is a huge plus for DJs, broadcasters, and podcasters, as it’s a quick and easy way to play audio. Additionally, the Bluetooth feature is incredibly handy for connected devices, especially if you don’t have the right cables or adaptors to plug them into the USB player.

Master section

Finally, let’s take a look at the master section of the Phenyx Pro PTX-15:

Overall thoughts on the Phenyx Pro PTX-15

Overall, the Phenyx Pro PTX-15 is a great piece of equipment for $120! It has 4 channels, making it a great tool for broadcasting or recording with multiple people. Each channel has its own set of individual sound adjustments so you can get the best audio, even with various voices that don’t sound the same.

The console itself is made out of solid plastic, with a metal front faceplate. We would have loved for it to be all-metal, however, at this price point, we’re not going to complain, especially as it still feels pretty solid. Plus, the faders and buttons feel nice and sturdy.

This mixer was designed for live situations and, with the various features such as the SOLO buttons, the EQ bands, and individual faders, it could be a great ally for radio broadcasters!
