EMF Acoustics Announces B-Band Core 99
Acoustic Instrument Preamp
 January 28, 1999The Core 99 is a new, totally redesigned version of the Core preamp.
For the user, it looks and sounds as good as our previous Core models,
but has more.
First of all, the Core 99 has a unique contour filter for tone enhancing.
Inside the preamp, there are separate DIP-switches for switching both
low- and high-frequency enhancers on and off. When the switches are in
their off positions, frequency response is flat with the low-end rolling
off at -6 dB/octave below 70 Hz. The LF enhancer provides a moderate effect,
while the effect of the HF enhancer is mild. Both enhancers have been
switched ON before shipping but can be turned OFF to get a flat response
or to have one enhancer active. Just open the preamp to change the presets.
There is also an easy way to reduce preamp gain by 10dB and/or lower the
low-end roll-off turnover frequency down to 35 Hz for use in acoustic
bass guitars.
Significant electrical improvements have also been made to the circuitry
to tighten production spread tolerances and enhance electrical parameters,
such as the signal-to-noise ratio.
As before, a system with an optional condenser mic with a split output
is also available. However, the condenser mic model supplied with this
system is a completely new, better one. The mic capsule is especially
designed for acoustic instruments, with a suitable bass roll-off and treble
boost.
The mic clamp and gooseneck have also been redesigned, to provide an
easier adjustment of the mic position. For more information, visit the EMF Acoustics web site at www.b-band.com.
