EDB-2 H.E PRINCIPLE
EDB-2 H.E is a Pre-amplifier or Analogue Audio Signal
Processor with many additional features, offering huge
reserves of gain and headroom designed to bring
instrument output levels up to optimum levels to interface
with a wide range of other such devices and at low noise
EDB -2 H.E shapes and equalises uneven tones, defeats
feedback, and allows two sound sources to sit together
and sound better by reversing the phase or cancelling
hum loops
Devices with which to interface include Mixers, Effects
Pedals and Rack Units, Powered Monitor Speakers,
Headphone Amps, Combo Amplifiers and Power
Amplifiers
EDB-2 H.E also offers a uniquely developed Analogue
Harmonic Enhancer feature, perceived as an "audio
sparkle", which replaces naturarlly inherent harmonics 1-
1.5 Octaves above what is often lost from your
instrument due to shortcomings or inadequacies in a
pickup or microphone
All can be achieved easily at hand. EDB-2 H.E can be On
but muted on either channel, ready to re-start instantly
and quietly. EDB-2 H.E is small enough for convenient
transportation
DON'T : Without additional suitable equipment, EDB-2
H.E WILL NOT drive speakers, headphones or produce
it's own audible sound and WILL NOT accept a power
P.5

amplifier into the "IN" or "Return" sockets as this may
cause damage .
EDB-2 H.E WILL NOT operate or may become
intermittent or damaged with use of any but the included
Power Supply. Will likely to be damaged if rain or liquids
are in contact

processing devices (e.g. mixers, amplifiers effects
units) so that where Mains powered devices with an
Earth Connection are used, there is a continuous,
unbroken chain of Mains earth connection and where the
mains supply at the venue offers a viable Earth or
Ground connection. DO NOT disconnect any
ground/earth wire on any earth connected mains
powered devices
1.1.3 MAIN PROTECTION Always take care to protect
your own life and those of others along with your
equipment by using RCD Circuit Breakers and AC Mains

3. PICKUP & MICROPHONE TYPE TO INTERFACE
The primary types of pickups optimised for EDB-2 H.E
can be active ( powered by battery or phantom ), or
Passive ( non powered ) in addition to all main types of
microphones:
P.18

i) Active ( Powered ) Piezo Under addle Pickup
ystems ( e.g. HE4/G.FEQ, or Snake3 pictured above,
or forthcoming Headway "Superbug" - Low Impedance
Output with Fixed EQ according to model ). These
pickups are one of the last prone to feedback and body
noises
