    I used the previews version of this device for more than 20 years at my studio. It was time to buy a new one and this is an obvious choice to me.

    I use this currently as a monitoring system for a small live stage set up. I use the aux send out of the mackie mixer for monitoring and send into this box. hook it up to some decent earphones and you've got yourself a cheap in ear monitor set up. Just clear communication cues with the sound engineer and your ready for a pro stage feel performance!

  • Great for $50.00!

    Foldback problems in your studio? Easily solved with this fine little box. Ample output volume and crush-proof. Remember kids, nothing is worse in the studio than bad headphone output. This box solves that for low bucks.

  • Cheap, works nice

    Don't let the low rating on features fool you, this is exactly it is intended to be: cheap and useful. Want features? Pay four times as much for something else.

    When using any of the headphone outputs are we able to hear from BOTH inputs at the same time?
