The Whirlwind pcDIQ is a 1RU, 4-channel version of the company's PCDI direct box. It's designed to convert unbalanced, line-level audio from MP3 players, CD players, or other consumer audio devices to balanced, mic-level signals for connection to the XLR inputs on a mixer, audio interface, or other devices. It sports four stereo pairs of unbalanced line-level inputs in three formats: 1/4", 3.5 mm (1/8"), or RCA.

Signals are output through four corresponding XLR stereo pairs on the back panel. Setting a channel's Mono/Stereo switch to Mono will cause that channel to output a mono mix of its two inputs. You can output a summed, balanced, mic-level version of any combination of the four channels through a separate mix bus, which is also on an XLR pair. Pressing a channel's Mix button assigns it to the mix bus. The mix bus can be toggled between mono and stereo output by pressing the Mix Output Mono/Stereo button.

Overly hot input signals can be attenuated by pressing a channel's Pad switch, which cuts by -20 dB. For noisy signals, each channel has its own Ground Lift switch that will break the audio ground between its input connectors and the XLR outputs.

Four stereo pairs of line-level, unbalanced inputs in 1/4", 3.5 mm (1/8"), and RCA formats make it easy to plug MP3 players, CD players, computer outputs, or other consumer audio devices into the pcDIQ for conversion.
Each of the four channels has a stereo pair of balanced, mic-level XLR outputs on the back panel.
Any of the channels can be sent to the dedicated stereo mix bus, where they're summed through the balanced, mic-level, XLR Mix Out jacks.
Each channel has a Ground Lift switch that breaks the audio ground between the input connectors and the XLR output.
Each channel has a Mono/Stereo switch that combines its left-and-right input signals to mono at the channel outputs. This action does not affect the mono/stereo status of that channel in the mix bus.
The mix bus has its own Mono/Stereo switch, which affects only the Mix Out pair.
Individual Pad switches apply -20 dB of attenuation to the input signal to prevent overloading the inputs when connecting devices with high output levels.

    pcDIQ - 4-Channel DI with Summed Output is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Convenient We bought this unit to give us an option input for when clients walk up to us with laptops and ipods. Works great and fills in the gap we had prior to buying it. We have it rack mounted in our small audio road case. It's pretty.
