B3
The B3 is a high quality true condensor pressure gradient microphone
with an FET impedance converter. It is a large diaphragm microphone with
three selectable polar patterns, Cardiod, Omni, and Figure Eight. The B3
uses a 3 um capsule for natural reproduction of the vocal range. The B3
uses a transformerless circuit, that features extremely low noise and wide
dynamic range.
The B3's polar response is very linear over a wide incidence angle.
Signals coming from the side and rear are reproduced accurately and with-
out any coloration. The microphone capsule is immune to typical interference
and outside contamination. The microphone is supplied with a shock mount,
windscreen and heavy duty road case with locking latches.

TB1
The TB1 is a high quality condenser pressure gradient microphone
with an hand selected 6072 "Dual Triode" tube for that sought after
classic warm sound. It is a large diaphragm Cardiod only mic. The
TB1 uses a 3 um dual capsule for thick warm natural reproduction of
the vocal range. The features extremely low noise and wide dynamic
range.
The TB1's polar response is very linear over a wide incidence angle.
Signals coming from the side and rear are reproduced accurately and
without any coloration. The microphone capsule is immune to typical
interference and outside contamination. The microphone is supplied with
a power supply, dedicated 7pin XLR cable, windscreen and heavy duty
road case, and AC cord.
