With the AlphaTheta DDJ-GRV DJ Set, you can practice well for live shows. There's a DJ controller, headphones, and speakers in this set. You can play a track via the studio speakers, while you prepare the next song via the headphones. This way, you can practice for live shows where the audience doesn't hear what the next song will be. The headphones have a 5 to 30,000Hz frequency range, so you can clearly hear every pitch. This way, you can hear every detail in your mix. Thanks to the switch at the back of the speaker, you can switch between DJ and production mode. In the production mode, the audio sounds neutral and detailed, so you can hear well what you're mixing. With the DJ mode, the audio sounds fuller and more powerful in the space.
