SWR Mini-Mo Mini-Mo' Preamp With Mo' Control 2 Master Footswitch Controller, Owner'S Manual, Page: 10 / 52

PASSIVE/ACTIVE INPUT JACK
The Passive/Active Input Jack is the most often used input jack and is the recommended starting point
for most SWR users. Connecting your instrument to this jack via a shielded instrument cable will send
the signal from your instrument to the initial preamp stage section of Mini-Mo’ Preamp, where it can be
adjusted before being sent on through the onboard effects and then to the Master section.
In this instance, "Passive" refers to an instrument that does not contain a built-in preamp and does not
utilize a battery. Although labeled "Passive," this input jack will work with all instruments having a
maximum output of 1 Volt RMS or less. Many professional instrument pick-ups employ batteries for
operation and will work perfectly with this input, as will most professional instruments that contain active
electronics.
Generally speaking, try this input first. If you hear a small amount of distortion and the preamp clip LED
is not activated, try using the Active input jack. If the Active input does not correct any audible
distortion, check the battery in your bass.
ACTIVE INPUT JACK ACTIVE INPUT JACK
The Active input jack should be used with instruments having a built-in (on board) preamp or other
sound sources that will produce output levels greater than 1 volt RMS. The number of bass
manufacturers has increased significantly over the years, and it's impossible to try and keep track of
them all. Generally, if you have very "hot" pickups and/or tone controls installed in your instrument, and
you use them to boost the level of your bass signal 10 dB or more, you may find the Active input more
compatible. The best judge is your own ears.
If you're using a keyboard or bass pedal with the Mini-Mo’ Preamp, we have found the best choice to be
the Active input.
NOTE NOTE : Using the Active input with passive basses (active instruments will always employ a battery)
may result in a loss of high end transients. Players who roll off their high end starting at about 2kHz,
or prefer a "darker" sound, may find this input more to their liking.
If you hear some distortion with your active bass and are using the Active Input, make sure the preamp
clip LED indicator is not lighting. If the preamp stage is not being driven into clipping, replace the battery
in your instrument.
TUNING MUTE SWITCH
This switch mutes 12 of the 13 audio outputs on the rear of the Mini-Mo’ Preamp, leaving only the
Tuner Out signal present. This allows for silent tuning without signal being sent anywhere else. In
addition to the Tuner Out jack on the rear of the Mini-Mo (for rack mounted tuners), there is a Tuner Out
jack located on the rear of the Mo' Control 2 Master Footswitch (for pedalboard tuners), so short
patching is never an issue when using a pedalboard. Both Tuner Outs remain live when the Tuning Mute
is engaged.
PREAMP CONTROLS
PREAMP VOLUME CONTROL
This control adjusts the volume of the Preamp section. A red LED is located above the control. As
mentioned in the "Getting Started" section, that LED will illuminate if the level is set too high, which
indicates that the preamp is clipping. In order to achieve maximum signal-to-noise ratio, set the Preamp
Volume to where the LED barely turns red upon striking your hardest note. However, this may not be the
optimal setting when using effects, so you may want to back off even further until you're done exploring
the levels of all of the effects on the Mini-Mo' Preamp.
