1. INPUT.
A low noise, high impedance
instrument input that can be used for both
passive and active instruments.
2. HI & LO BOOST.*
independently from the other preamp
filters. This gives the user the opportunity
to preshape the sound before the final
processing by boosting either the lows or
highs, or both at the same time.
3. GAIN
adjusts the instruments' signal
strength before the filters. For optimum
signal level, turn up the GAIN knob until the
PEAK led starts flashing from the strongest
signal from the instrument.
Note: A correctly set GAIN is vital for the
signal processing to work properly in the
EBS 802.
4. COMP/LIMIT.
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. The LED intensity dynamically
indicates the amount of compression during
play.

6. FILTERS.
The filter section contains five
enhanced performance filters:
BASS is a 'shelving' type 12dB/oct slope
phase compensated bass filter with a
wide gain range. It works in conjuction
with a flip-switch control to set the corner
frequency at 60, 80 or 100 Hz. Pick a
corner frequency, then move the Bass
control towards + to boost or - to cut in the
range you have chosen.
LO MID and HI MID makes possible for
individual control of a certain frequency in
the low-mid respectively high-mid range.
Both filters consists of one control that cuts
or boosts in the frequency you choose with
the control right next to it. LO MID covers
frequencies from 95 to 3000Hz. HI MID
works in the range of 200 to 7000Hz.
TREBLE is a shelving type filter controlling
the higher mids and treble registers, giving
presence and ambience to the sound.
The associated switch selects the center
frequency of operation.
BRIGHT is an advanced high pass filter
capable of producing bright high treble
timbre, without adding practically any noise.
7. DRIVE.*
The DRIVE knob controls the
amount of gain in the tube emulation stage,
and provides an extra gain all the way up to
34 dB. The gain is compensated over this
section producing a warm overdrive while
the output remains more or less constant.
