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.
