Great For Practice

I use the Switchcraft for choir practice. I plug my iphone in and we are ready to go. Very easy to use and I love the volume control.

Great, purpose specific box

Needed a solid 1/8" D.I. for others to use in a plug & play system that would give some volume control, but not access to the actual audio system. This works great. Quiet, clean, and the low profile volume pot protects itself from damage.


Amazing Product wish I would of know about this thing when I was bringing my karaoke setup out to the Fair Grounds. Had to use there DI Box which was unbalanced output. If you want a Direct Box Specfically for your MP3 player or Laptop this is it. Highly Recommend this product as well.

Get It You Need it Especally w Bose ToneMatch

This really bring the Bose Tone Match to just amazing with backing tracks, mp3 etc files in stereo running out from source but if you're plugging into the Bose system you lose one channel of the signal. The Switchcraft 318 some how dose magic and makes the mono sound great. I use the Switchcraft 318 1/8 to XLR Mini SumBox from iPhone out running One Track (for backing tracks, percussion, and sounds) from Switchcraft XLR to Blose L1 Tone Match (Stereo to Mono) signal sounding very nice. Can't live with out it. It's my secret weapon to make the system sound even better. Thanks Mark Magdich x1265 and UPS for getting this to me. Can't wait to use it this weekend.
