MANUAL
OUTBOARD BASS PREAMP / DI
SBP-1

This unit oers you the same quality electronics that we have been building into our
basses for over 30 years. Here are a few tips to help you get maximum performance from
your preamp.
Volume
In most cases the volume control should be set to maximum. If you are using a small amplier,
the use of the preamp might overload the preamp stage of your amplier causing some
distortion or clipping. In this case, lower the volume control on the preamp to reduce the gain
of the input into your amplier. If you plan to toggle between an active setting and bypass, use
the volume control to set the desired gain for the active setting.
Treble & Bass
The treble and bass controls are boost only - at response is with the controls at their complete
counterclockwise position. Do not automatically go to full treble and bass boost - start from
at response and then boost treble and bass as desired. Although you are free to adjust the
settings anyway that pleases you, our experience is that once you nd the optimal setting for
your bass, you will not have to make frequent adjustments of the tone controls.
On/O Switch
This footswitch enables you to engage or bypass the active tone circuit. The green LED lights
up when the preamp section is 'On'. The volume / treble / bass controls do not function in
the 'O' mode. All other functions (Dl, tuner out, mute) work in the 'O' mode. If you want to
switch between on and o with the same bass, use the volume control to adjust the level for
the 'On' position. The On/O switch has no eect on the battery life. The battery is switched on
whenever a cord is plugged into the input jack.

Mute Switch
The Mute switch will mute the signal of the bass. The Mute LED lights up when in mute mode.
The Tuner Out will remain active in the mute mode.
XLR Out
The XLR output enables you to plug directly into a PA or recording console or any other device
that accepts an XLR connection. The output is accurate and quiet for recording and all
professional applications.
Ground Lift
If a hum occurs while using the XLR output, engage the ground lift switch. When the switch is
set to the right (under the word, 'Lift') the ground is lifted.
Low Battery LED
The Lo Batt LED will begin to glow when the battery reaches 7.5 volts. We recommend you
replace the 9V battery at this time. To extend battery life, unplug the cord going into the
input jack as the battery is draining anytime that jack is activated. This is not necessary on short
breaks while gigging, but do not leave the unit plugged in overnight when not being used.
AC Adapter
An input jack for an AC adapter is located on the right side of the unit. The Sadowsky Preamp
requires a linear regulated power supply for quiet operation. For very noise sensitive applications,
battery operation might provide the most quiet operation.

Battery
To change the battery, pull open the compartment on the side of the unit.
