lf the 'PAN is set towards the center, it is possibleto send to multiple groups at once.9. PAN control: This control allows you tocreate stereo mixes by sending the signalfrom the channel fader in continuouslyvariable degrees to the odd or even groups(or to the left or right sides of the stereo mixat mixdown time).10. ASSIGN switch: This routes signals comingfrom the PAN control to the correspondingMASTER faders, for recording ontomultitracks.Effect Send SectionThrough this section of the 488, channel signalsare sent to external devices, primarily effectsprocessors (such as reverb units).11. EFFECT control: This is a combination"where to" and "how much" control. It getsits signal from a point just after the channelfader and routes the corresponding channelsignal to one of the two Effect Send Masters.In the center (12 o'clock) position, the effectsend is OFF. Turn the control to the left ofcenter to send signal to EFFECT 1, or to theright of center to send signal to EFFECT 2.The further you turn it either way, the louderit will be - if it's turned all the way to the left,it's at full volume to EFFECT 1 ; and if it'sturned all the way to the right, it's at fullvolume to EFFECT 2.12. EFFECTS SEND MASTERS: These are themaster volume controls for the EFF 1 andEFF 2 mixes. They get their signal from theEFFECT controls in the channels. The signalthen goes to the EFFECT SENDS 1 and 2jacks on the back panel. Adjust the EFFECTSEND MASTERS until you have the correctlevel feeding your external effects device.See p.33, "Setting Effects Send Levels".13. EFFECT SENDS jacks: These are the outputsfrom the EFFECT SEND mixes of the 488.Signal comes here directly from the EFFECTSEND MASTERS level controls. They aretypically connected to the inputs of externaldevices such as reverbs, digital delays, etc.(After the signals are processed, they areusually returned to the 488 via STEREOINPUTS on channels 9-10 and 11-12. A monoreturn may also be connected to any LINE INjack on the channels 1 thru 8.)The EFFECT SENDS may also be used tofeed a separate monitor.Stereo Inputs SectionThis section of the 488 includes two stereo signalpaths which are equivalent to four additionalinputs. You can use these inputs as EFFECTRETURNS:14. STEREO INPUTS jacks: These jacks are the3-conductor stereo (TRS) type. You canconnect the outputs of your effects devicesto these jacks, but they can be used for anyline level input if desired. The nominal inputlevel is-10 dBV (0.3 V).Thanks to their special design, the STEREOINPUTS of the 488 have various functions:Two Stereo Pairs (using insertion cables):By using a special cable (sometimes calledan "insert" or "stereo splitter" cable, such asthe TASCAM PW-2Y or PW-4Y), eachSTEREO INPUT jack can return two signals(left and right) from a stereo unit. The cablehas a 3-conductor stereo 1/4" plug on oneend, and at the other end splits into twocables, each with 2-conductor (mono) 1/4"plug. Plug the 3-conductor (tip-ring-sleeve)end into the STEREO INPUT of the 488, andthe two mono plugs into the Left and Rightoutputs of the effect device or synthesizer.NOTE: On the 9/10 stereo input, the tipsignal is sent to the left (Groups 1 and 3),and ring to the right (Groups 2 and 4). On the11/12 input the signals are reversed (tip tothe right ring to the left).Single Stereo Pair (using separate monocables): If you only have standard monocables, plug the left output of the unit intothe 9/10 input of the 488 (also labeled"L/MONO").
