TASCAM US-2000 72 − Names and Functions of PartsNOTETurn all the way to the left to minimize the input levelor all the way to the right to maximize the input level.q MONITOR switchesUse these switches to set whether or not adjacent inputs1-2, 3-4, 5-6, 7-8 are monitored in mono or as stereopairs with odd-numbered channels (1, 3, 5, 7) on the leftand even-numbered channels (2, 4, 6, 8) on the right.w +48V switchesUse these switches to set whether or not +48 V phantompower is provided to the mic input jacks in pairs (1-2,3-4, 5-6, 7-8).CAUTIONBefore turning these switches ON or OFF, turn•the output volume down using the PHONES andMONITOR knobs. Depending on the mic, loud noisesmight be produced and damage could be caused toequipment and people’s hearing.Do not connect or disconnect a mic with an input•when its +48V switch is ON.Turn a switch ON only when connecting a condenser•microphone that requires phantom power.Do not supply phantom power to an unbalanced•dynamic microphone.Some ribbon mics can be damaged by phantom•power. If unsure, do not supply phantom power to aribbon mic.e MIC/INST INThese are analog mic/instrument inputs that combineXLR and phone jacks. Use the XLR connectors forbalanced mic connections and the phone jacks forelectric guitars and basses, for example.The pin assignments of the XLR jacks are 1 = GND, 2= HOT, and 3 = COLD.POWER switch11Use to turn the unit’s power ON and OFF.PHONES jack and knob21Use this standard stereo phone jack to connect stereoheadphones. Use a plug adapter when connectingheadphones that have mini-plugs.Use the PHONES knob to adjust the headphones outputlevel.CAUTIONTurn the PHONES knob to the minimum volume beforeconnecting headphones. Failure to do so could causesudden loud noises and damage hearing, for example.MONITOR knob31Use this to adjust the output level for MONITOROUTPUT L/R.COMPUTER knob41For the signal input from the computer connected byUSB, use this to adjust the level of output from theMONITOR OUTPUT and PHONES jacks.INPUT knob51Use this to adjust the overall level of all the signals inputthrough this unit’s input jacks (mic, line and digital)that is output from the MONITOR OUTPUT and PHONESjacks.OUTPUT meters61These show output levels for the unit’s 4 outputs.POWER indicator71This lights when the power is ON.INPUT SOURCE meters81These show input levels for this unit’s 16 inputs.USB indicator91This lights when the USB connection is in use.0 Input gain knobsUse these to adjust the input levels of MIC INPUTS 1–8independently.2 − Names and Functions of PartsFront panel
