1. 23 MO BASS OUT Totally unaffected It sees everything just as before So if you want to run in Dual Mode and get the clean preamp sound on one output and the wet onboard effects on the other simply set the Line Direct switch to Line and use the Direct Out for the clean side and the Mini Mo Preamp Out for the wet side Unbalanced Pre Master Outs TUNER OUT External effects are never present DIRECT OUT With the Line Direct switch in the Direct position no external effects are present With the Line Direct switch in the Line position signal from only the LEFT EFX return will be present MO BASS OUT Signal from only the RIGHT EFX return is present at this output Balanced Pre Master Outs DIRECT OUT External effects are never present This is another difference between the balanced XLR Direct Out jack and the unbal anced 1 4 Direct Out jack MO BASS OUT Signal from only the RIGHT EFX return is present at this output SENDING STEREO EXTERNALLY PROCESSED SIGNALS When Dual Mode is engaged and you have routed both left and right effect sends and returns to an external effects device a processed signal is present at both the clean left and the wet right sides of the Mini Mo Preamp To send a true stereo externally processed output from the Mini Mo Preamp Interface Panel use the 1 4 Unbalanced or XLR Balanced Mini Mo Preamp Output for the wet right send Use only the 1 4 Unbala
2. and Mo Control 2 17 DUAL MODE Up until this point you ve operated the Mini Mo Preamp in what we call Single Channel Mode In Single Channel Mode the single signal starts at the preamp and goes through all of the Mini Mo Preamp effects The levels of those internal effects are determined by the position of their respective level controls or in the case of the SubWave the mix control After the Chorus section the last Mini Mo Preamp effect in the chain the signal then is routed to the Master section After that point you can get audio out of the Mini Mo Preamp from the Main Outputs or post master outputs in either stereo individual outputs left and right or mono a single summed mono output In Single Channel Mode both left and right main outputs and their respective outboard amplification sources will see the same signal Turn on an effect and it will come out of both sides Turn the effect off and clean bass will come out both sides Dual Mode changes all that When Dual Mode is engaged the signal splits in two after the preamp One of the two sig nals we ll call it the clean channel is routed directly from the preamp straight to the LEFT set of main outputs The other signal we ll call it the wet channel continues on through the five Mini Mo onboard effects and is then routed to the RIGHT set of main outputs The Left and Right Master Volume controls then become a secondary set of blend controls when
3. 0 is minimum while fully clockwise is maximum As mentioned previously in the Getting Started section of the manual both controls are active at all times Whether you re in Single Channel Mode or Dual Mode or using the left right main outputs to a stereo power amp or the mono main output to a mono power amp both controls are always independently active This is your last chance in the signal path to adjust levels In addition to setting the overall output level of the entire unit you can use the Stereo Master Volume controls to a Balance two speaker cabinets of different impedance when running in stereo b Balance the clean left and wet right channels when in Dual Mode regardless of how you are running the power amps c Balance master levels when using two different external effects units in the external loop For most applications however you can set the Left and Right Master Volume controls at equal levels and adjust to taste for overall volume We recommend leaving them set fairly high and using your power amp volume controls as master vol umes for your system unless the power amp s input is clipping early in which case you should back off the Mini Mo mas ter volume controls until the situation is alleviated STEREO HEADPHONES JACK By inserting a set of stereo headphones into this jack you can satisfy your urge to play through the Mini Mo Preamp at all hours of the night without disturbing your neighbors or even hooking
4. EFX Blend controls To avoid confusion we refer to this loop as external to separate it from the five internal effects on the Mini Mo Preamp The Effects Blend circuit is similar to that used on recording consoles with the effects loop on a side chain to the origi nal bass signal which at this point in the signal path may or may not be already processed by the Mini Mo Preamp inter nal effects This way you can get the full sound of your instrument in addition to whatever the external effects unit sends back USING THE EXTERNAL EFFECTS BLEND CONTROLS Most players only use one external effect device so let s start there In the simplest configuration the Mini Mo Preamp is run in Single Channel Mode Dual Mode disengaged Your input signal your bass guitar is a mono signal But most effects units are stereo in the sense that they accept two independent inputs and send out two independent outputs So what s the best way to hook it up In order to have external effects returning to both sides of the main outputs and therefore both sides of your desired power amp connect the Mini Mo Preamp RIGHT Effect Send jack located on the rear of the unit to the external device s input Please refer to your device s manual to determine the correct input Then use BOTH left and right returns on the effect unit and route them to the Left and Right Effects Return jacks on the Mini Mo Preamp You can send both the Left and Righ

33. ccurs regardless of whether or not you are using the Dual Mode function O I want to slap with the Bassynth on but it sounds like something is clipping or being overloaded no matter what I do What s up A The Bassynth on the Mini Mo Preamp is really designed for fingerstyle playing more so than for slapping That s because the circuit is a sawtooth wave generator the same kind used on classic Moog type synthesizers and a flatter input signal makes for a more smooth effect through the filter Slapping creates a large peak in the waveform which tends to overload the front end of the filter O Why does the Bassynth Resonance control affect the volume so much A Because when you increase the Resonance control you re actually narrowing the band of freguencies that are allowed to pass through the Filter When you take away frequencies from your signal it is no longer full range and there is a perception of volume loss from those missing freguencies You ll notice that when the Resonance is at minimum the Bassynth level may actually be louder than when the effect is disengaged This is normal For all cases simply use the Bassynth Level control to adjust for the desired levels between when the Bassynth effect is engaged and when it is not O Will the Mo Control 2 footswitch be able to memorize settings on the Mini Mo Preamp A It will memorize groups of effects but not actual settings because the Mini Mo Preamp is not a digital

38. e Preamp Clip LED turning red indicates that at some point the preamplifier is clipping no harm is being done to your amplifier Be sure to remember to set the SubWave Mix control back at O before disengaging the effect during your experimenta tion Why Because as we mentioned when the Mix control is all the way at sub there is no original bass signal present in the signal path The level of the pure SubWave is much lower than the bass guitar signal So if you switch the SubWave effect off when the SubWave Mix control is all the way at the Sub position and your original bass signal has a lot of EQ on it and especially if the Overdrive is engaged you may get a boost in your signal level you weren t expecting 12 s Mini Mo and Mo Control 2 BASSYNTH Based on the design of a classic analog synthesizer this effect generates a sawtooth waveform that can be altered by the Filter Resonance or Envelope controls The level can then be set to match unity gain with the unaffected bass signal using the Level control You can also blend in your unaffected bass signal by using the Dual Mode function and adjusting the left clean and right wet Master Volume controls Please see the sections marked Dual Mode later in the manual for more details The Bassynth on the Mini Mo is a traditional analog sawtooth wave generator which is an important distinction from what has seeped into modern consciousness People hear synth with bass and thi

53. junction with the Bassynth Notice how the Bassynth Resonance control becomes more dramatic with a liberal dose of the Mo EO Treble control And how the Bassynth Envelope and Filter controls appreciate the presence of a boosted Mo EO Midrange control As for the way the Bassynth is affected by the Mo EO Bass control all we can say is stand back be careful and turn the knob slowly when boosting Your speaker cabinet will thank you in the morning Note When the Bassynth Filter and Envelope controls are open and the Resonance control is at the minimum position the level of the Bassynth will be higher than the level of the original bass signal which is normal However when boosting the Mo EO Bass control while the Bassynth is engaged and in that position that boost will become very dramatic Please exercise caution 16 gt Mini Mo and Mo Control 2 Though designed to be a post effects EQ there is no reason why you can t use the Mo EQ as an additional EQ for clean sounds In addition to being a different type of EQ band pass vs shelving semi parametric the Mo EQ is centered at much different freguencies 40 hz 1 5 kHz 10kHz than the preamp EQ 80 Hz variable 200 800 Hz 2 kHz The effect is more subtle but it can also be the difference between almost what you want and exactly what you want Try combining both and see what s best for you CHORUS The Mini Mo Preamp Chorus is a warm analog very traditional effect that expa
