THE INS AND OUTS
Follow Standard Audio Procedure to avoid unwanted and potentially speaker-damaging “pops” when connect-
ing or disconnecting any equipment:
Always mute mixing board and/or turn down amp volume before plugging or unplugging!
IMPORTANT: TURN ON FIRST. TURN OFF LAST.
1/4” INPUT: 1megOhm, instrument level.
1/4” Input Level Pad Switch: for active basses pads the input by -10dB (in position).
Note: also affects the 1/4” Tuner Output.
UNIVERSAL OUTPUT SECTION
The output sections of the SansAmp XB Driver are designed to be compatible with any application. 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 compensate for different frequency responses of speaker
enclosures by using the Treble control.
BALANCED XLR OUTPUT: Balanced low Z output. Sends effected or uneffected signal to mix-
ing console/recorder.
GROUND CONNECT SWITCH: When engaged, the ground connects. Disengaged, the
ground of your stage system and other interconnected gear is lifted (isolated) from the ground of the mix-
ing console.
With a mixer only: If you are plugging your bass into the XB Driver and taking the XLR Output to a
mixer --and do not have any other grounded equipment connected in the setup-- you
will have to push the switch in to connect the ground.
With a mixer and bass amp: If you are going to the mixer via the XLR and using the 1/4” Output to
feed a bass amp (with its own AC ground), you should have the switch disengaged (in the up position) to be in
“Ground Lift” mode. If you experience hum and/or buzz with the switch in either position, there may be a
problem with the AC outlets you are using.
NOTE: If using vintage equipment without proper grounds, take extra care connecting it to modern
grounded equipment. Any inadequacies of the ground in vintage gear could result in damaging anything it is
connected to.
XLR Output Line Level Switch: toggles between mic level (-20dB) and line level (0dB) to
match the output to equipment with different input level requirements.
Disengaged (out position), the output is -20dB. Engaged (in position), the output is 0dB.
1/4” OUTPUT: Unbalanced low Z output. Sends effected or uneffected signal to amp rig or power
amp.
1/4” Output Level Boost Switch: +10dB boost to match the output to equipment with
different input level requirements. Disengaged (out position), the output is -10dB. Engaged (in position),
the output is 0dB. Also affects the 1/4” Tuner Output.
NOTE: Both outputs can be used simultaneously. For example, 1/4” Out to your amp and XLR
Out to PA mixer, which is one instance where the Ground might need to be disengaged.

1/4” TUNER OUTPUT: As long as the unit is plugged in, the tuner output provides a constant,
unaffected signal at all times, regardless of the position of the Level controls. This output can also be used
as a buffered out to send a transparent signal to other outboard gear. Note: the 1/4” Input pad also affects
the 1/4” Tuner Output.
SEND/RETURN Effects Loop: For external effects, connect the input of your processor
to Send; output of your processor to Return. Note: When nothing is plugged into the Effects
Loop, the signal passes through from the XB Driver to the Output jacks, with both the
SansAmp 1/4” and XLR Outputs receiving the same signal.
UNIVERSAL POWER SUPPLY
The SansAmp XB Driver is shipped with an 18V power supply
set up with a U.S. prong assembly. To change the prong assem-
bly to one of the included European, UK or Australia/New
Zealand styles, be sure the power supply is unplugged and follow
these instructions:
Press the PUSH switch to release the prong assembly. Slide the
assembly up (about halfway) to align the side tabs of the prong
assembly with the slots of the power supply housing. Then pull up
to remove the assembly. Choose the new prong assembly, align the
side tabs with the slot of the housing, slide down until it clicks into
position.
NOTE: You cannot slide the prong assembly all the way out or all the way in.

WARNING: DO NOT run the speaker output of any amp
directly into the SansAmp. Doing so may result in severe
damage to the amp and/or the SansAmp.
