SMX DUAL COMPRESSOR PEDAL
General overview
It is important to understand a little of what goes on inside the SMX pedal to give
you an idea of what is happening to your sound as you adjust the units controls.
To help with this a short description follows prior to the actual operating
instructions.
The SMX DUAL COMPRESSOR is two separate compressors in one unit, each
compressor has its parameters set to suit the frequency band that it is dealing with
i.e. Fast attack for the High frequencies and Slow attack for the Low frequencies.
Two input filters are used to split the signal into its High and Low frequency
components, the output from these feed the High and Low compressors. The EQ
BALANCE control sets a crossfade between the output of the two compressors and
provides an extremely versatile and entirely new form of powerful tone control. See
BLOCK DIAGRAM below:-
The SMX PEDAL can increase sustain on any note or harmonic, smooth out
playing dynamics, add definition to fast runs, provide a switchable volume boost,
provide a wide range of EQs that are easily and instantly adjustable, provide HIGH
or LOW compression or any combination of the two and can function in the effects
loop or on the front end of any amplification system.

We at TRACE ELLIOT consider that one battery of 9 volts does not give sufficient
headroom in the circuitry for the peaks in the signal from your instrument, so as
not to compromise the signal integrity the SMX PEDAL uses two 9 volt batteries to
give an internal power supply of 18 volts.
Connections and controls
Power to the unit is supplied from the two internal 9 volt batteries or from the D.C.
SUPPLY socket on the back of the unit (this requires a regulated 18 volts mains
adaptor available from TRACE ELLIOT as an optional extra).
Power to the unit is turned on when a jack plug is inserted into the INPUT socket.
Two LEDs indicate the ACTIVE status of the unit, these are EFFECT ACTIVE above
the OUTPUT control to indicate when the effect is switched into circuit, and HI
COMP ACTIVE to indicate when the HIGH COMPRESSION is switched into circuit.
This second LED will indicate the status of the HIGH COMPRESSION even when
the unit is in bypass mode i.e. EFFECT ACTIVE off, to let you know the current
condition of the HIGH COMPRESSION prior to switching the overall effect into
circuit i.e. EFFECT ACTIVE on.
If either of these LEDs should start to become dim then it is time to replace the
4 batteries.
Input control
The INPUT control is to allow you to set the input sensitivity of the unit to your
instrument, if this is not set to the optimum level then you will not have full use of
the compression range available.
With your instrument plugged into the SMX PEDAL and its own level control
turned up full play a few loud notes. Gradually increase the setting of the INPUT
control, the INPUT LEVEL LED should start off showing GREEN as you play and
eventually turn to RED as the INPUT control is increased. The optimum setting for
this control is when the LED shows GREEN for every note played with an
occasional flick into the RED on loud peaks.
Compression
TRACE ELLIOT have always avoided including compression in any of their
previous amplifiers as the integrity of the bass signal has always been paramount
in all designs.The reason for this is simply that any kind of FULL RANGE
compression used on bass is always an unacceptable compromise. It cannot act
fast enough to catch attack transients, and if it does then it distorts low frequency
signals. If you have used any full range compression then you know what we
mean.
The compression within the SMX PEDAL has therefore been split into two entirely
