SWR Sound Mini-Mo' Preamp With Mo' Control 2 Master Footswitch Controller - Manual (Page 22)

The Effects Blend circuit is similar to that used on recording consoles, with the effects loop on a "side
chain" to the original bass signal (which at this point in the signal path may or may not be already
processed by the Mini-Mo' Preamp internal 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 Right Effects Send signals
to your external effect device if you wish, but it's not necessary unless:
a) Your external effects device requires stereo inputs to function properly
b) You plan on using different external effects for each channel in Dual Mode (see below)
Now that your external effects unit is connected to the Mini-Mo' Preamp, try setting both the Left and
Right External Effects Blend controls to '5' on the dial. You should hear a decent blend of external
effects with your Mini-Mo' Preamp signal. With the External Effects Blend controls fully counter-clockwise
("dry"), no signal from your effect will be heard. As you turn these controls clockwise, more of the effect
can be heard in the overall sound. When the Blend controls are fully clockwise ("wet"), no true or
unaffected signal is heard other than what your effects unit provides. If you find that you can't get
enough of the external effects in the signal no matter how high you set the External Effects Blend
controls, try adjusting the levels up on the external effects unit.
USING DUAL MODE WITH AN EXTERNAL EFFECTS UNIT
Please remember that when "Dual Mode" is engaged, the "clean" channel is always on the LEFT side,
and the "wet" channel is always on the RIGHT.
The key function of Dual Mode is to allow the user separation between "clean" and "wet" sounds. But it
also allows for different external signal processing on each channel. In other words, it is possible to
utilize two different external effect devices independently. Simply route the left effect send to one device
and return it to the Left Effects Return jack. Then repeat the process for the right side using a different
device. This allows you to process the "clean/left" signal with one effect and the "wet/right" signal with a
different effect.
Many so-called "stereo" external effects devices sum their inputs to a mono signal and then convert the
mono signal into stereo at their outputs. The Mini-Mo' Preamp External Effects Loop is a TRUE stereo
loop. To achieve true stereo effect send and return, be aware that your external effects device must
process signals in TRUE stereo. Otherwise, your left and right effects returns will process both
"clean/left" and "wet/right" signals from the Mini-Mo' Preamp and the two channels' effects will bleed into
each other.
DEFEAT MAIN OUTS SWITCH
This switch, when engaged, defeats the post-master ("main") audio outputs only. The corresponding LED
illuminated in red when the function is engaged. This switch is unique in that there is no corresponding
footswitch on the Mo' Control 2. It's just another muting option, and can allow for convenient
