TASCAM 2488 User’s Guide 212 – MixerInputs and assignmentsThe 2488 has eight inputs, marked from A through H,and twenty-four mixer channels.Inputs A through D are fitted with dual XLR-1/4"balanced inputs and can be supplied with +48 Vphantom power for condenser microphones.WARNINGNever connect or disconnect microphones to or frominputs A through D with the phantom power turnedon.Never use unbalanced dynamic microphones withmicrophone inputs A through D with phantom powerturned on. If you are in any doubt, consult your localaudio expert.Inputs E through H are suitable for line input, and arefitted with 1/4" balanced jacks. An unbalanced “mir-ror” of H, with an impedance suitable for electricguitars and basses, is provided at the front of the unit.It is possible to record up to eight tracks at one time,with the inputs being freely assignable to the tracks.Assigning inputs is carried out by pressing and hold-ing the appropriate input key below the TRIM con-trols (the key flashes), and then pressing theappropriate channel SELECT key(s) which will alsoflash. It is also possible to reverse the order (pressand hold a channel’s SELECT key and press theappropriate input key).An input can be assigned to more than one channel,but of course a channel cannot be fed by more thanone input.This shows an instrument (guitar or bass) pluggedinto input H being assigned to channel 1Checking assignmentsWhen either an input key (or channel SELECT key)is pressed and held down it flashes, together with thechannel (or input key) to which it has been assigned.Also, if the SHIFT key is pressed, followed by theMAP key, a screen is shown with the current assign-ments.The eight inputs are represented by horizontal lines,which are joined to the channel labels at the bottomof the screen by vertical lines when they are assignedto the channels.Use the left and right cursor keys to change betweenviewing channels 1 through 12, and 13 through 24.Breaking assignmentsIf an input or channel SELECT key is held down, theassigned channel (or input) key flashes. Press theother key to break the assignment.NOTEAssigning and unassigning linked channels (see “Link-ing channels” on page 25) works in much the same wayas for single channels. Pressing one SELECT key of alinked channel pair is typically the same as pressingboth together.
