comparisons between the sound coming out of your rig to the sound in the house (or at the mixing
board).
STEREO MASTER VOLUME CONTROLS
The Stereo Master Volume controls adjust the individual volumes of the main outputs. For both controls,
fully counter-clockwise ('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 volumes for your system, unless the power amp's input is clipping early,
in which case you should back off the Mini-Mo’ master 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 up a
power amp and speaker cabinets. The headphone volume level is adjusted by the Stereo Master
Volume controls.
We suggest you begin with the Master Volume controls fully off (counter-clockwise). Then slowly bring
the volumes up to your desired level. If you hear some distortion in your headphones that is not present
with the speakers on, turn down the Master Volume controls. You're probably exceeding the capability of
your headphones and could ruin them. Be especially carefully when engaging effects that boost level,
like Overdrive. The recommended impedance for your headphones is 32 ohms, but results can differ, as
the efficiency ratings of the drivers contained in headphones vary greatly.
Here's a hint: try running the Mini-Mo' Preamp in Dual Mode with some effects engaged while using a
nice set of stereo phones. We like it.
MINI-MO' PREAMP - REAR PANEL FEATURES
THE INTERFACE PANEL
We call the right-most section of the Mini-Mo' Preamp back panel the "Interface Panel" because
between the unbalanced and balanced output jacks and various switches available, you can "interface"
with just about any outboard gear you desire. Mixing boards in a live venue or recording studio,
additional power amps or signal processing––the options for what kind of signal you can send to where
are practically limitless.
As opposed to the main outputs (which are controlled by the Master Volume controls, i.e. the term
"post-master"), the audio outputs in the Interface section are all pre-master outputs. The Master Volume
controls will not affect their levels. You will notice that the signal levels of these outputs are generally
