consecutive TAP’s of the switch. If mapped to DELAY it will set the DELAY time up to a maximum
of 800 milliseconds in length based on the TAP time between two consecutive TAP’s of the switch.
IMPRESSION PEDAL REAR PANEL
The rear panel has 3 ¼ inch phone jacks with one for the instrument input and two for the final
stereo output signals Left and Right. Power is connected via a barrel connector labeled 9VAC.
The IMPRESSION pedal internally converts the 9 volt AC signal from the power adaptor to a
profes/- 15 volt DC power supply. This allows a 30 volt internal signal swing required for
proper headroom and professional level performance. The IMPRESSION pedal will only operate
on a 9VAC power source, do not use any other power adaptor or damage may result.
THE IMPRESSION PEDAL FUNCTIONS
The IMPRESSION Pedal will provide high quality DSP based effects of CHORUS or FLANGE plus
DELAY and REVERB to be footswitch selected and mixed in with the direct signal or, if connected
to a parrallel effects loop of an amplifier, the Direct level should be fully attenuated to avoid any
potential phase problems that may occur. The Direct Level control allows the user to determine
the output mix level of the Direct input signal and can also be used as a main system level
control. The Effect Level control allows the user to mix the desired amount of effects in relation
to the Direct signal level. The individual effects of CHORUS or FLANGE plus DELAY and REVERB
are switched on and off by switching the CHORUS / FLANGE switch, DELAY switch and REVERB
switch. The TAP switch is automatically mapped to the last effect selected of CHORUS / FLANGE
or DELAY. The TAP function will read the time between two consecutive TAP’s of the TAP switch
and this time interval is used to set the Modulation time for CHORUS / FLANGE and also will set
the DELAY time if the TAP switch is mapped to the DELAY function. The TAP switch does not
affect the REVERB function. The IMPRESSION does not store any of the settings and will revert
back to a default mode on power up. The default mode is CHORUS on, DELAY on and REVERB
on with REVERB at full internal mix level relative to the other effects and a medium modulation
rate for the CHORUS / FLANGE effect. The DELAY regenration will also default to a regeneration
setting of -18db. The next step selected by holding the DELAY button down for more than 1
second is a regeneration setting of -12db. The next step will be a regeneration setting of -6db
and the final step will turn off all regeneration for a single delay with no repeats.
Digital Decimator® Noise Reduction On Board
The IMPRESISON Pedal also includes built in Digital Decimator® Noise reduction implemented to
keep the effects processing quiet. The Decimator is configured with an internal pre-defined
threshold of -40db below the peak input to the DSP and will provide low level downward
expansion as the input signal drops below this internal set threshold. The Decimator increases
the Dynamic Range of the internal effects by approximatly 12db and reduces the ultimate noise
floor of the Effects. This feature is not user adjustable but built in and implemented to provide
enhanced performance.
