will distort or "clip" the electronics of the MM-1. Occasional flashing of this light is OK, but if it's on constantly you should turn down the TRIM or the volumecontrol on your instrument. Conversely, if only the greenLE D is on wh ile you're playing, and you have to boost theCHANNEL FADER to get enough signal to the output,operation will be noisier than if you increased theTRIM to its proper level. Signal to the LEVEL LEDs isaffected by the input device level, the TRIM, and theEQ, but not by the CHANNEL FADER or MUTE. Seep. 10, "Setting Input Levels."MASTER SECTION10. EFFECT SEND MASTERS 1-4: These are themaster volume controls for the four effect send mixes.They get their signal from the EFF 1/2 and EFF 3/4controls in the channels to their left. The signal thengoes to the EFFECT SEND output jacks on the backpanel. Adjust the EFF SEND MASTERS until you havethe correct level feeding your external effects device. Seep. 10, "Setting Levels: To Effect Devices".11. STEREO EFFECT RETURNS 1-4: These controlhow much signal from the four EFFECT RETURNJACKS is mixed onto the L!R stereo buss and then theL/R MASTER FADER. The EFFECT RETURNS control how much signal goes I N to the MM-1, coming backfrom the effect device, as compared to the EFFECTSENDS, which control how much goes OUT of theMM-' to an external effect device (such as a reverb un it).The unity gain point of the effect return controls is the"12 o'clock" position.A special feature of the MM-1's EFFECT RETURNsystem is that it is capable of receiving 4 stereo returns,which on conventional designs would requ ire 8 effectsreturns. Each EFFECT RETURN level control in factsets the level of 2 signals, left and right, if you are usingthe special stereo plugs that can take advantage of it. Seep. 5, "Quarter-I nch Stereo (TRS) to 2 Mono ill nsert"or "Stereo Splitter" cables".On the other hand, if you use mono effect retu rns, thereis a way that you can "pan" them between the left andright sides of the mix. If a signal (for example, the output of a reverb) is plugged into return #1, but there isnothing plugged into return #2, the reverb signal will goto both EFFECT RETURN 1 and EFFECT RETURN 2controls. In this "mono" mode, EFFECT RETURN 1controls how loud the reverb will be on the left side, andEFFECT RETURN 2 how loud it will be on the rightside. You can vary the two controls to send signal anywhere between the two groups, similar to using a panpot. EFFECT RETURNS 3 and 4 work the same way.For more information on effect returns, see p. 7,"Choosing Effect Returns", p. 8, "Mono Effect Return", and pp. 11-12, "Setting Levels: From EffectDevices".12. L!R MASTER FADERS: These faders adjustthe output levels of the mixer. They get their signal from theleft and right mix busses, which are fed by the channelPAN controls. They send signals to the four L!R OUTPUT jacks on the back panel, to the PHONES LEVELTASCAMMM-1KEYBOARD MIXEREFFECT STEREOSEND EFFECTMASTERS RETURNS10J[j]MUTE [j]MUTE13 o OJ654L RMASTERcontrol, and to the meters.
