A DI That Lets You Plug in Your Music Players and More!

The Whirlwind pcDI direct box is ideal for plugging CD players, iPods and other MP3 players, computer sound cards, tape decks, and more into balanced, low-impedance gear. Using two separate DIs (one uses a stereo 1/8" jack input, the other uses RCA), the pcDI lets you plug in an array of sources you wouldn't normally be able to implement with your balanced rig. The input jacks are color-coded, as are the XLR output jacks. You also get a ground lift switch, Stereo/Mono switch, and a 20dB pad switch for hot input signals. Bring your consumer gear up to speed with the pros when you use the Whirlwind pcDI!

Whirlwind pcDI Direct Box Features:
  • Color-coded RCA phono in/through jacks
  • Color-coded XLR output jacks
  • Ground Lift switch to help eliminate hum and buzz
  • Stereo/Mono switch for stereo operation or safely combine both inputs into a mono signal sent to both outputs
  • 20dB pad switch for connection to "hot" input signals
  • Uses Whirlwind's TRHL-M transformers with metal shield
The Whirlwind pcDI lets you plug your consumer-grade players into balanced inputs for great results!

Great Little DI

Does exactly what it is advertized to do....little pricey but you get what you pay for. Love the Stereo/Mono switch. Lots of inputs (Swiss Knife). My system is now officially all Low Impedance and silent. ahhhh.

Minor upgrades keep up the great tradition

I've used earlier versions of this device for years and I bought another one based on its reliability and performance. None of those aspects of changed. This is still one of those devices every sound dude should have on hand. The latest model includes the addition of a 1/8" stereo line input, complementing the RCA inputs. This saved me on a recent gig where I ran short (by one) of 1/8" to RCA cables. I just happened to have an 1/8" to 1/8" on hand that usually sits idle in my bag of tricks. It let me get the presenter's laptop connected in to the sound system and everyone was happy.
