PRODUCT OVERVIEW

Tech 21 redefined the term “direct box” with the development of SansAmp

TM

Bass DI, which was introduced in 1992. It incorporates our exclusive Tube
Amplifier Emulation circuitry and delivers the warmth and presence of a
miked-up bass amp system in a convenient direct box format.

We have expanded this design concept for the bassist whose needs are more
diverse. SansAmp Bass Driver DI functions as a pre-amp, a stomp box, and as a
direct box. In bypass, SansAmp Bass Driver DI converts the instrument signal
to a low impedance balanced output.This prevents signal loss and sound quality
deterioration caused by long cable lengths.When you engage the SansAmp
Tube Amplifier Emulation circuitry via the on-board footswitch, it not only con­verts the signal, it gives you the sound and responsiveness of a miked-up pro
stage rig --direct into a recording console or P.A. system.You can also simultane-
ously plug straight into a power amp or conventional bass amp.

Tech 21’s proprietary circuitry is engineered in the true tradition of tube ampli­fiers in their totality --with a pre-amp stage and an output stage. It incorporates
the harmonics and sweet overdrive characteristics uniquely inherent to tube
amplifiers.This is largely caused by what is referred to as “push-pull” symmetri­cal clipping, a feat which a single tube is physically incapable of
accomplishing.

SansAmp Bass Driver DI offers an entire sound spectrum of the most coveted
traditional bass amp rigs, from vintage to modern styles.You can also obtain
overdriven sounds without having to invest in a complex system with multiple
rack effects.As with each SansAmp model, the controls are designed to give
you the flexibility to customize your own sound.After all, the greatest inspira­tion comes from having the sound that’s right for you.

SansAmp Bass Driver DI.

Consistent quality sound studio to studio, club to club, arena to arena.

APPLICATIONS

WITH BASS AMP RIG:

-As a Stomp Box: Run the 1/4” Output into the front input of an amp. For

best results, keep SansAmp Bass Driver DI’s Level close to unity gain so as
not to overload the amp’s input, which could yield undesirable distortion.

-As a Pre-Amp: Run the 1/4” Output of SansAmp Bass Driver DI directly

into the power amp input, a.k.a. “effects return” (if applicable), of an amp.

This will bypass the tone-coloring pre-amp section of the amp rig.

TO DRIVE A POWER AMP: Run the 1/4” Output to the input of a

power amp, and adjust your stage volume with the Level control of SansAmp
Bass Driver DI.
NOTE:When running into the power amp input of an amp or a power
amp alone, adjust the Level as needed. If you are so inclined, this is the
time to crank it!

TO RECORD DIRECT: You can plug the XLR or 1/4” Output directly

into the input of a mixer/recorder. Work with the input trim control on the
mixer/recorder and be sure not to overload its input.Additionally, bear in mind
that full-range systems yield a wide frequency response.Therefore, we suggest
you start with the EQ levels at 12 o’clock and increase/decrease to taste.

GUIDE TO CONTROLS

PRESENCE brings out the upper harmonic content and attack. For a

smoother high end and for clean settings, decrease to taste.

DRIVE adjusts the overall amount of gain and overdrive, similar to when

the output section of a tube amp is being pushed.

BASS & TREBLE

Unlike passive controls that can only cut, these active tone controls cut or
boost ±12dB from unity gain at 12 o’clock.This powerful EQ section effectively
reduces the need for a fixed frequency mid control and enables you to achieve
an extensive variety of curves --including a “mid-cut” as well as a
“mid-boost.”
