Product Name: Whirlwind PODDInDirect Box best with 1 Summing MoNo Output
output summing direct box. Use it to connect CD and MP3 players, computer sound card outputs, DJ mixers, etc. to professional equipment with balanced inputs such as a mixing console. Accepts stereo inputs and sums them into a single mono output. The podDI can also be used as a high quality single input DI box. A variable attenuator on each input allows level matching between left and right inputs. This makes the podDI a passive mixer in split track audio applications, balancing the voice track and the music track levels in the summed mono output. Signal is input via 1/8" (3.5mm) stereo TRS jack or color coded RCA phono jacks. An unused input can best be used as a "loop through". Output is via a balanced male XLR jack. It also features a ground lift switch to help eliminate hum and buzz.
