Dual channel stereo direct box. Useto connect CD and tape players,computer sound card outputs, DJmixers, etc. to professionalequipment with balanced inputssuch as a mixing console.Signal is input via 3.5mm (1/8")stereo TRS jack or color-coded RCAphono type input / through jacks.Output is via color-coded XLRs.Features a ground lift switch to helpeliminate hum and buzz, a "STEREO/ MONO" switch to combine stereosources into a mono signal. Eachsection also features a 20dB padswitch for connecting to "hot" signalsources.www.whirlwindusa.com®

INPUT (RCA phono jacks X 2 and 3.5mmstereo TRS jack) Use to connect theaudio outputs of computer soundcards, CD players, tape decks, etc. TheRCA phono jacks are color coded – redis usually used as the right side channelin stereo applications. The 3.5mm(1/8”) jack is a tip/ring/sleeve type.The tip is common with the + side ofthe white RCA phono, the ring iscommon with the + side of the red RCAphono jack and the sleeve is commonground to both.THRU (RCA phono jack X 2)“Y” connections or “loop through”from the inputs.LOW-Z BALANCED OUTPUT (XLR jack X2)Male XLRs, which provide balanced lowimpedance, mic level signals suitablefor connection to balanced, low-Ze q u i p m e n t ( m i x i n g c o n s o l e ,workstation, etc.) The output signal isattenuated approximately 20dB belowthe input level. These jacks are colorcoded to match their correspondinginputs.PAD (Switch X 2)Most instruments will operateproperly when set to the “O”position. Set to the “I” position(adds 20dB attenuation to the inputsignal) for use with very “hot”signals to reduce the possibility ofdistortion.GND/LIFT (Switch)This switch is usually left in the“GND” position (grounds areconnected from input to output). Ifhum occurs in either channel whenusing the pcDI, setting the switch tothe “LIFT” position may help toreduce it. (This disconnects theground between BOTH inputs andthe corresponding XLR outputs.)STEREO / MONO (Switch)When placed in the STEREO position,the pcDI acts as two separate andindependent DIs. In the MONOposition, the left and right inputjacks are summed into a mono signalthat is fed to both XLR outputs.This product is warranted tobe free of defects inmaterials or workmanshipto the original purchaser fora period of 3 years from thedate of purchase.
