– This switch actives
the filter section described under point 6.
This switch can also be remote controlled by a
foot switch. See rear panel descriptions for more
details.
- The filter section contains four
enhanced performance filters:
is a 'shelving' type 12dB/oct slope phase
compensated bass filter with a wide gain range.
is a shelving type filter controlling
the higher mids and treble registers, giving
presence and ambience to the sound.
is an advanced high pass filter capable
of producing bright high treble timbre, without
adding practically any noise.

has an extended frequency range of
50-5000 Hz. This filter facilitates total control
over the mids, with a wide bandwidth giving a
natural and non-peaking result using frequency
dependent gain. In addition, at minimum setting
this filter facilitates a notch function, suitable for
cutting an exact frequency or eliminating
acoustic coupling.

- A low noise, high impedance
instrument input that will also power active
pickups and circuitry. If you want to use this
function, take away the 9 volts battery from your
bass and strap + and - pole on the battery holder.
Use a standard stereo cable when using the
phantom powering from the EBS HD360.
If you do not wish to use this feature, make
sure the
switch on the rear
panel is set to OFF to defeat the phantom power.
- The EBS HD360
provides a preshape filter,
, which
operate independently from the other preamp
functions. This gives the user the opportunity to
preshape the sound before the final processing
with the other features of the preamp.
When pressed to inner position, boost is
achieved in bass and treble ranges respectively,
while the midrange has a slight drop in gain.

GAIN
COMP/LIMIT
- Control to adjust the instruments' signal
strength to the right operating level in the EBS
HD360.
For optimum basic signal level, turn up the
GAIN knob until the PEAK led starts flashing
from the strongest signal from the instrument.
- A low noise compressor
limiter that works fast and effectively, tightening
up the sound and preventing the bass head from
saturating at peaks when approaching the
headroom limit.
The COMP/LIMIT knob sets the compression
ratio, i.e. The signal strength relation between
the input and output; the higher ratio the more
compression.
Note: A correctly set GAIN is vital for the
signal processing to work properly in the
