This unit oers 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 amplier,
the use of the preamp might overload the preamp stage of your amplier causing some distortion
or clipping. In this case, lower the volume control on the preamp to reduce the gain of the input into
your amplier. 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 eect 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. Please follow all safety
instructions regarding the battery usage, removal and disposal. Do not expose the battery to extreme
temperatures. Use only suitable 9V batteries. Do not use re to dispose of batteries.
