Tech 21 was formed by a guitarist possessing the unusual combination of a
trained ear and electronics expertise. In 1989, B. Andrew Barta incorporated
Tech 21 and made his invention commercially available to players and studios
around the world. His highly-acclaimed
Amplifier Emulation in professional applications for recording direct and per­forming live, and created an entirely new category of signal processing. There
have since been many entries into this niche, yet SansAmp continues to main­tain its reputation as the industry standard.

In addition to a full line of SansAmp models, Tech 21 also offers “traditional”
style amplifiers for guitar and bass, effect pedals, and battery operable MIDI
footcontrollers. Each product is thoughtfully and respectfully designed by B.
Andrew Barta himself with the player in mind.

Tech 21’s goal is to provide you with flexible, versatile tools to cultivate, con­trol, refine and redefine your own individual sound. We take great pride in
delivering consistent quality sound, studio to studio, club to club, arena to arena.

PRODUCT OVERVIEW

TECH 21, THE COMPANY

SansAmp Programmable Bass Driver DI and SansAmp Bass Driver Deluxe
combine the warmth of a
digital programmability in a super simple, player-friendly stomp box format.
Our proprietary technology captures the rich, natural harmonics and sweet
overdrive characteristics inherent to tube amplifiers, and does so even at low
volume. SansAmp delivers the same dynamics, responsiveness, and sound quali­ty of massive pro stage rigs in a portable, programmable pedal.

The ease of operation allows you to make changes on the fly, at the gig, even
during your performance --without having to take this manual with you. There
are no complex formulas or numerical calculations to learn, so there’s nothing
to get in the way of your creative flow.

Independent footswitches put your favorite tones right at your feet, from
warm vintage to Sumo-sized overdrive. Custom actuators provide a smooth
transition between channels for instantaneous switching, so you can dance to
the music instead of your gear.

APPLICATIONS

WITH BASS AMP:

the input of the power amp input, a.k.a. “effects return” (if applicable), of an
amp. This will bypass the tone coloring section of the pre-amp and will

defeat the amp’s master volume.

NOTE: BE SURE the BASS GUITAR VOLUME is OFF --BEFORE
you turn on the amp. Then slowly increase the volume of the bass. If it’s

too loud overall, check that the 1/4” Out Boost switch is disengaged (up) and
then edit your presets accordingly. If it doesn’t get loud enough for you,
engage (depress) the 1/4” Out Boost switch to add 10dB.

Or, you can run the SansAmp into the front input of an amp. Be sure to keep
the Level of SansAmp close to unity gain, so as not to overload the amp’s
input, which could result in undesirable distortion.

Tips for setting up your amp when using front input:

1. Plug into low gain channel or input.

2. Turn off Bright switch.

3. Turn presence control (if applicable) to 12 o’clock or below.

4. Set tone controls as flat as possible.

Run the 1/4” output of the SansAmp directly into

TO DRIVE A POWER AMP: Run the output of the SansAmp into

the input of a power amp with an input sensitivity of -10dB to 0dB. Then use
the master volume control of the power amp to adjust your stage volume.

TO RECORD DIRECT: You can plug directly into the input of a

mixer/recorder and use the on-board sounds of the SansAmp. Bear in mind,
full-range systems yield a wide frequency response. Therefore, you may need
to adjust the EQ settings of the SansAmp to compensate.

THE INS AND OUTS

Standard Audio Procedure: TURN (SansAmp) ON FIRST. TURN
OFF LAST. To avoid unwanted and potentially speaker-damaging “pops”

when connecting or disconnecting any equipment, always mute mixing
board and/or turn down amp volume before plugging or unplugging!

WARNING:

SansAmp. Severe damage to the amp and/or SansAmp may result.

SIGNAL LEVEL TO INPUT

SansAmp Bass Driver is designed to accommodate instrument level signals to
the Input, such as the output of a bass, the output of distortion pedals, etc.
Signal level to Input should be close to that of a standard electric guitar
(approx. -10dB / 250mV). NOTE: Hot pickups will increase the gain structure
of the SansAmp Bass Driver.

[Deluxe] IN A (MAIN): 1/4-inch 1 megOhm, instrument level. Use as

your main input when using a single instrument. Also switches battery power
on/off. To avoid battery drain, unplug when unit is not in use.

[Deluxe] IN B: 1/4-inch 1 megOhm, instrument level. For second instru-

ment.

[Deluxe] PARALLEL OUTPUT: 1/4-inch buffered, unbalanced

direct output. Instrument signal passes through, UNeffected, to the input of
your stage amplification system or tuner.

1/4” INPUT: 1 megOhm, instrument level. Also switches battery power

on/off. To avoid battery drain, unplug when unit is not in use.

BALANCED XLR OUTPUT: Balanced 600-Ohm low Z output.

Sends effected or bypassed signal to mixing console/recorder.

XLR Out Pad Switch: -20dB pad to match the output to equipment with
different input level requirements. In the line level (up) position, the output
is 0dB. In the instrument level (down) position, the output is -20dB.

1/4” OUTPUT: Unbalanced 1KOhm low Z output. Sends effected or

bypassed signal to amp rig or power amp.

1/4” Out Boost Switch: +10dB boost to match the output to equipment
with different input level requirements. In the instrument level (up) position,
the nominal output is -10dB. In the line level (down) position, the output is 0dB.
