BASS, MID & TREBLE
Unlike passive controls that only cut, these fully programmable
active
tone
controls cut or boost ±12dB from unity gain at 12 o’clock. Frequencies are:
Bass @ 125 Hz. Mid @ 500 Hz.Treble @ 3.5 kHz.
LEVEL
Adjusts the output level.
PROGRAMMING THE CHANNELS
HOW TO SAVE A PROGRAM
Just select an amp style and set the knob controls to your taste. Double click
on the footswitch of the particular channel you want the setting to be located,
and it’s saved. It’s that easy.
SansAmp TRI-A.C. is shipped from the factory with 3 presets: (1) Fender
®
Twin-
style, (2) Marshall
®
Plexi-style, and (3) Mesa Boogie
®
-style. Refer to Sample
Settings on Page 9 for actual switch and knob positions.
HOW TO FIND A PRESET
This is useful when you want to know the position of each knob’s setting in the
memory of a channel.When you turn a knob from its stored position, it
“unlocks” and the channel indicator LED will blink.The slower the blink, the
farther away you are from the preset point.The faster the blink, the closer you
are. At the preset point, the LED stops blinking and remains on.
LAZY POT™
Another Tech 21 first, is the development of the Lazy Pot.This is a unique safety
feature engineered for the
Drive
and
Level
controls.When you “unlock” the EQ
settings, for instance, they will “jump” to the new setting of the knob position.
For the
Drive
and
Level
controls, however, this could result in you jumping out
of your skin if they are at a high setting.With the Lazy Pot, there’s a slow, grad-
ual increase to the new setting position giving you time to turn it down.This
will only happen when you initially unlock a preset. Once unlocked, the pot will
react according to how you reposition it.
BYPASS
SansAmp TRI-A.C. can go into bypass mode in any of the three channels.
Whichever channel you’re already in, hit that channel’s footswitch again and
you’ll be in bypass mode.
GLOBAL RESET
If you want to reset your unit back to factory specifications, you can simply
reprogram the three Sample Settings listed first on page 9 [(1) Fender
®
Twin-
style, (2) Marshall
®
Plexi-style, and (3) Mesa Boogie
®
-style], or perform the
following procedure: Hold down the footswitches for Channels 1 and 3
while
simultaneously
applying power (either plugging in an adapter or, if a battery is
installed, plugging in your guitar cable).Then release the switches.
SPEAKER SIMULATION
Built-in speaker simulation is an integral part of the SansAmp circuitry. It
shapes the sound to match the particular cabinet of the amp type selected. It
is specifically designed for a smooth, even response as would be achieved by a
multiply-miked cabinet, without the peaks, valleys, and notches associated with
single miking.Therefore, it will not adversely affect or interfere with the sound
of your own speaker cabinet.
PLACEMENT ORDER OF OTHER EFFECTS
One of the key attributes of any SansAmp is its responsiveness to the dynam-
ics and nuances of your playing technique. In most cases, your guitar should be
plugged directly into the SansAmp.We suggest experimenting to find the order
that’s best for you. As a general guide, we recommend:
Place the following effects BEFORE SansAmp TRI-A.C.:
Wah-Wah, Pre-Amp, Compressor, Fuzz Box, Envelope Follower.
Place the following effects AFTER SansAmp TRI-A.C.:
Chorus, Delay, EQ, Pitch Shifter, Reverb.
NOTE: Low quality digital effects placed after SansAmp TRI-A.C.
may compromise your signal and degrade the sound.
