Direct Box
OWNER'S MANUAL
We thank you for your purchase of the most innovative direct
box on the market. B.K. Butler's proprietary circuitry patented.
This is the first known tube cathode balanced direct box ever
designed.
This break-through design results in the elimination of the typi-
cal output transformer. The elimination of the distortion-prone
and frequency response-limiting output transformer coupled
with the addition of a low-noise comparator-type input amplifier
has resulted in a literal order of magnitude advance in perform-
ance for this studio quality device.
While using the RTD, you will notice the almost total lack of mi-
crophonics along with one of the lowest noise floors in the in-
dustry for tube-type studio gear. The noise parameter was
very carefully considered in the design phase.
