Mix 50/50 Switch
The 1/4" Send routes 100% of the SansAmp RBI’s signal through your effects processor
when the 50/50 switch is disengaged. If you engage the 50/50 switch, then 50% of the
SansAmp RBI signal goes through your effects processor, and the other 50% passes
directly to the SansAmp 1/4" and XLR Outputs.
To preserve the signal integrity of the SansAmp RBI, use the Effects Loop with the Mix
50/50 switch engaged. When the SansAmp RBI is in this mode, the effects processor’s
mix control should be set at 100% wet. Your relative wet/dry mixture can then be con-
trolled by increasing or decreasing the effects processor’s output level.
UNIVERSAL OUTPUT SECTION
The output sections of the SansAmp RBI are designed to be compatible with any appli-
cation. The outputs can be used for full range (multi-track recorders, studio monitors,
P.A. systems) or limited range systems, as well as
simultaneously . Note: You can com-
pensate for different frequency responses of speaker enclosures by using the Treble
control.
1/4” SansAmp Output
Carries the signal from the SansAmp RBI, including any effects that are placed in the
Effects Loop.
1/4” Uneffected Output
Buffered output without processing. Sends a direct bass signal to another channel on
your amp, pre-amp, or effects chain, or it can be utilized as a tuner output.
SansAmp XLR Direct Output
Carries the signal from the SansAmp RBI, including any effects placed in the Effects
Loop. For recording, the SansAmp XLR Output is like having a built-in direct box.
Designed without a transformer, it provides a balanced, low-impedance output of
extremely high quality for recording or interfacing with professional-quality signal
processors. Go direct to the board and get the same sound you hear coming out of the
speakers right onto tape or disc. The SansAmp circuitry not only captures the warm,
rich, natural harmonics and sweet overdrive characteristics inherent to tube amplifiers,
its speaker emulation encompasses all aspects of multiply-miked tube amp rigs.
For live gigs, you can use this output direct into the P.A. system and you won’t need a
microphone in front of your amp. And you won’t have to subject the audience to a
sterile, muddy, or boomy bass tone.
NOTE: If you experience
hum from the output when
there’s no instrument
plugged in, you most likely
have a ground loop.
Therefore, Pin 1 (signal
ground of the SansAmp
XLR) needs to be lifted or disconnected. You can easily make a small ground discon-
nect adapter by disassembling one end of the cable and cutting Pin 1 (see diagram
above.)
XLR Output Level Switch
Sets the range of the signal level of the SansAmp XLR Output jack. In the 0dB position
(engaged), the Output is in the line level range. When in the -20dB position (disengaged),
the Output is in the instrument level range. Note: The standard output level range of the
SansAmp RBI is 0dB due to the popularity of digital recorders, which are unforgiving to
excessive input levels. This prevents overloading the input of a digital recorder.
Uneffected XLR Output
Provides a buffered balanced output of the direct instrument signal without processing.
Footswitch
Any alternating (on/off) footswitch will activate the unit. Connect the footswitch output
to Footswitch In. To toggle between this unit and another SansAmp RBI (or SansAmp
RPM), do the same as above and connect the SansAmp RBI Footswitch Out to the
Footswitch In of the second SansAmp RBI (or SansAmp RPM). Now you can switch
between 2 sounds. For the audio signal path, connect your bass into the Input of the
first SansAmp RBI. Connect the 1/4” SansAmp Out to the Input of the second unit. The
1/4” Output of the second SansAmp RBI is then your main audio out. (Refer to the
Hook-up Diagrams on Page 13.)
