I/O & Power Jacks - Electro-Harmonix DELUXE MEMORY MAN 550-TT Manual

I/O & POWER JACKS
INPUT Jack – Connect the output of your instrument or other effects pedal to
the ¼" INPUT jack. The impedance presented at the INPUT jack is 100 k.
OUTPUT Jack – Connect the output of the DMM550 to the input of an amplifier
or another effects pedal. The output impedance is 200 .
SEND Jack – Connect this jack to the input of another effects pedal or chain of
effects pedals to insert an effects loop before the DMM550's delay block. The
output impedance is 200 .
RETURN Jack – Connect this jack to the output of another effects pedal or
chain of effects pedals to insert an effects loop before the DMM550's delay block.
The input impedance presented at the RETURN jack is 2 M.
EFFECTS LOOP – The Deluxe Memory Man 550-TT has an effects loop feature
which allows other effects to be inserted into the feedback loop of the delay
block, before the bucket brigade chips. This means that you can put additional
effects on your wet signal without changing your dry signal and each time your
notes go around the feedback loop, they will also go through the effects loop.
For example, if you connect a Micro POG in the DMM550's effects loop, setting
the Micro POG to output only the upper octave, the delayed note will be one
octave above the dry note that you played. Additionally, with a fair amount of
feedback on the DMM550, each time the note circles around the delay loop, the
signal will go up another octave. So if you play a C2 on the guitar, the first echo
will be a C3, the second C4, the third C5 and so on.
Another example would be to plug a volume pedal into the DMM550's effects
loop. The volume pedal will act as a FEEDBACK control. With the addition of an
expression pedal, you could have the volume pedal control feedback and the
expression pedal control one of the other expression modes..
To properly use the DMM550's effects loop, connect the SEND jack to the input
of your effects loop and the RETURN jack to the output of your effects loop.
N.B. If you do not wish to use the effects loop, please leave the RETURN jack
disconnected.
EXP. PEDAL Jack – Enables the musician to control any of the five available
expression modes with an optional expression pedal or control voltage. The
expression pedal should have a Tip-Ring-Sleeve plug attached to it. It is
important that the expression pedal have the correct polarity. The tip of the plug
must be connected to the wiper of the potentiometer inside the expression
pedal. If you are not sure what type of expression pedal to use, try to purchase
one with a polarity switch so that it will work with many different types of
instruments. Some suggested Expression Pedals: M-Audio EX-P, Moog EP-2,
