BassEq
PreAmp
The
BassEQ PreAmp's sole purpose is to restore the bass
that's so often lacking in 2-way speakers. More importantly,
it does this without detriment to the midrange. Vocals
and instruments retain their clarity and transparency.
The
black plot above is the Osprey-12
frequency response. In this 4pi placement, the bass
(50Hz~100Hz) is about 5dB below the midrange. This
tonal imbalance leads to listener fatique as there's
too much mids and highs.
The
BassEQ rectifies the tonal imbalance by boosting the
bass to the level of the midrange (blue plot). It
does this without affecting the midrange. Note 500Hz
upwards is not boosted.
The
amount of bass boost can be adjusted up to +12dB with
the bass control. In instances where your bass is
boomy, the bass control allows you to lower the bass
by up to -12dB.
At
the output of the BassEQ PreAmp is a volume control
that feeds the signal to the power amplifier. This
is equivalent to the traditional volume control in
PreAmps.
The
BassEQ PreAmp is a Stereo board. It requires +/- 15V
power from a regulated supply. Our PSU15REG
is specially designed for such use.
