3. OVERVIEW OF A6T PREAMP
All B-Band A-series preamps are designed to give optimum
performance with B-Band UST and AST transducers. The main
criterion in designing these preamps was to deliver studio qual-
ity and user-friendly electronics to the diverse needs of acoustic
instrument musicians.
The A6T preamp has the XOM mix control that controls the
blend of the UST and UST / AST XOM mix.
XOM® (Cross Over Mix)
In our continuing search for realistic acoustic tone the B-Band
research and development team has applied a crossover sys-
tem to our exclusive patented pickup material. The crossover
mix (XOM) system combines the best aspects of each pickup
into one complete source.
By sensing the guitar from two separate locations and combin-
ing, what each pickup does best, the XOM system has a very
complex and rich sound that further augments already superior
sounding Emfit film pickups.
The ideal process for authentic acoustic reproduction comes
from combining the high frequencies of the AST and low fre-
quencies of the UST, making a sound that is much more com-
plete, true and pure. In addition, the XOM pan pot allows the
player to select between UST / AST XOM mix crossed over at
800 Hz or the full range UST, or one of the many points in-be-
tween resulting in almost unlimited possibilities.
At the UST side of the mix control only the UST is heard. At the AST
side of the mix control, a crossover mix of the UST low frequencies
and AST high frequencies is heard.
To learn more about the XOM feature, check the XOM User Guide
later in these instructions.
The A6T has a dedicated input gain control located at the back-
side of the preamp. The control is accessed through a small hole
with a screwdriver. This control is used to set the basic balance
of the UST and AST so the pickups can have equal output signal
strength.
The A6T has the HzzLess® circuit for outstanding low noise and
high output.
The A6T is a side mount preamp with a 3-band “graphic” equalizer,
XOM mix control, chromatic tuner, Notch Frequency and Depth
controls, phase button and low battery LED light. This dual XOM
input preamp will accept UST and AST.
The A6T uses a standard 6.3 mm (1/4”) plug to turn on the 9-volt
power.
