DELUXE MEMORY MAN 1100-TT
TAP TEMPO ANALOG DELAY with FX LOOP,
MODULATION and EXPRESSION PEDAL
CONTROL
Congratulations on your purchase of the Electro-Harmonix Deluxe
Memory Man 1100-TT (1100-TT). The 1100-TT is designed with high
quality bucket brigade ICs for an analog delay sound equal to the
original Deluxe Memory Man. In addition to Tap Tempo control of the
delay time, the 1100-TT also includes delay time modulation, an effects
loop in the feedback path of the delay block, an input gain control, tap
tempo divide and optional expression pedal control over five parameters:
Delay Time, Feedback, Modulation Depth, Rate and Blend. The 1100-TT
is true bypass.
-CONTROLS and INDICATORS -
KNOBS
DELAY Knob –Sets the delay time from 52 ms to 1100 ms. As you turn the
DELAY knob clockwise, the delay time will increase. If you tap in the delay time,
the DELAY knob’s setting will be ignored until you move it again. If you turn the
DELAY knob after tapping in a delay time, the DELAY knob’s setting will
supersede the last tap tempo that was entered. Turning the DELAY knob, while
listening to your echoes, will bend the pitch of your notes. The DELAY knob can
also be used to set the maximum delay time for expression pedal control. N.B.:
the TAP DIVIDE button functions have no effect on the DELAY knob; pressing
TAP DIVIDE when the DELAY knob controls the delay time does not change the
delay time.
WARNING: Your Deluxe Memory Man 1100-TT comes equipped with an
Electro-Harmonix 9.6DC-200BI power supply (same as used by Boss®&
Ibanez®: 9.6 Volts DC 200mA). The Deluxe Memory Man w/ Tap Tempo
requires 200mA at 9VDC with a center negative plug. The 1100-TT does not
take batteries. Using the wrong adapter may damage your unit and void the
warranty.

FEEDBACK Knob –Controls the amount of signal that is circulated from the
output of the delay block to its input. Turning the FEEDBACK knob clockwise
increases the number of echoes. Setting the FEEDBACK control to its maximum
clockwise position will cause the 1100-TT to run-away, or self-oscillate.
Alternatively setting the FEEDBACK knob to its minimum position will yield just
one echo or repeat for each of your notes. The FEEDBACK knob is also used to
set the maximum amount of feedback for expression pedal control.
DEPTH Knob –Sets the amount of modulation that is applied to the delay time.
As you turn the DEPTH knob clockwise, the amount of modulation increases.
Turn the DEPTH down to the full Counter-Clockwise (CCW) setting to turn
modulation off. The DEPTH knob is also used to set the maximum amount of
modulation for expression pedal control.
RATE Knob –The RATE knob’s main function is to set the rate or speed of
modulation. As you turn the RATE knob clockwise the modulation rate will
increase. The DEPTH knob must be set above the full CCW position to hear the
RATE knob change modulation speed. Additionally the RATE knob sets the
maximum rate of modulation for expression pedal control.
GAIN Knob –Sets the input gain for the 1100-TT. As you turn the GAIN knob
clockwise, the input gain increases. The total gain range is -13dB to +20dB. The
gain block is the first stage that the input signal goes through in the circuit. Both
the dry and wet signals mixed by the BLEND knob go through the gain block.
BLEND Knob –The BLEND knob is a wet/dry control allowing you to vary the
mix between direct and delayed signals at the OUTPUT jack of the 1100-TT. Set
the BLEND knob to the full clockwise position for an output that is 100% wet. Set
BLEND to full counter-clockwise for an output that is 100% dry. Setting BLEND
anywhere in between will mix the wet and dry signals together. Additionally the
BLEND knob sets the maximum wet/dry mix for expression pedal control.
SWITCHES & LEDs
BYPASS Footswitch and STATUS LED –The BYPASS FSW is used to toggle
the 1100-TT between effect mode and true bypass mode. The red STATUS LED
will light up when in effect mode and turn off in bypass.
EXP. MODE Button and LEDs –The EXP. Mode button cycles through the six
available expression modes: BLEND, RATE, DEPTH, FEEDBACK, DELAY and OFF.
Each time you press the EXP. MODE button the 1100-TT will advance to the next
expression mode LED. An expression pedal must be plugged into the EXP. PEDAL
jack to make use of these modes. A lit LED for one of the modes indicates the
expression pedal will control that parameter. For example, if the RATE LED is lit,
the expression pedal controls the modulation rate, from slowest (expression
pedal = toe up), to the RATE knob’s current setting (expression pedal = toe
down). When no EXP. MODE LEDs are illuminated the expression pedal is

3
disabled while it remains plugged into the 1100-TT. The setting for the EXP.
MODE is saved and recalled when power cycling.
TAP Footswitch –The TAP FSW is used to tap in the delay time. Stomp on the
TAP FSW two times and the delay time will jump to the time between taps (if all
the TAP DIVIDE LEDs are off). If you tap more than twice, it will average the tap
tempo for all taps, it will stop averaging if there is more than 2 seconds between
two consecutive taps. The 1100-TT will always take into account the TAP DIVIDE
setting when determining the delay time from the tap tempo. For example, if
your tap time is 1 second and TAP DIVIDE is set to eighth notes, the actual delay
time will be 0.5 seconds. The maximum delay time, when tapped in, is 1.5
seconds; though at this delay time the effect will sound quite lo-fi. The
1100-TT will save and recall the tap tempo when power cycling. In addition, if an
expression pedal is controlling the delay time, the Tap Tempo and TAP DIVIDE
setting will determine the maximum delay time of the expression pedal.
N.B.: The delay time for the 1100-TT is always set by the last method used. If
you tap in a delay time, the DELAY knob’s setting is ignored. After tapping in a
delay time, if you turn the delay knob, the tap time will be forgotten and
replaced by the current position of the DELAY knob.
TAP FSW HOLD TO PRESET FEEDBACK –If you press and hold the TAP
FSW, the 1100-TT will slowly ramp up to a high FEEDBACK setting. After
releasing the held TAP FSW, the feedback amount ramps back down to the
current FEEDBACK knob setting. The high feedback setting that the 1100-TT
ramps up to is set at the factory but may be adjusted when you are holding
down the TAP FSW, if held for more than 1 second. If you do not like the setting
chosen at the factory, simply turn the FEEDBACK knob to your preferred setting,
while the TAP FSW is held down. It may take a few tries before nailing the
perfect setting. Release the TAP FSW to save the feedback hold setting. The
1100-TT will remember the TAP FSW HOLD setting after power cycling.
If you want to restore the original factory setting for the FEEDBACK HOLD, press
and hold the EXP. MODE button while applying power to the 1100-TT. When you
see all 5 expression mode LEDs light up, the factory setting has been restored,
you can now release the EXP. MODE button.
BEAT LED –The green BEAT LED either blinks at the current delay time setting
(if delay time is set by the DELAY knob) or the tempo that you tapped in. Cycling
through the TAP DIVIDE settings will not change the BEAT LED blink rate. If you
are modulating the delay time, the change in delay time due to modulation will
be reflected in the BEAT LED.
TAP DIVIDE Button and LEDs –This button cycles through the six possible
settings for TAP DIVIDE. Each setting, except when all LEDS are off, will divide
the tap tempo to create shorter delay times in sync with your original tempo. It
works like so: The 1100-TT always assumes that the musician taps in a quarter
note. That quarter note can then be divided down to five other types of notes:

4
dotted eighth note, quarter note triplet, eighth note, eighth note triplet and
sixteenth note. The sixth mode is quarter note or OFF, where the tap tempo is
not divided down and the delay time is set to your actual tap time. No LEDs are
lit when Tap Divide is set to quarter note/OFF. Below is a chart displaying the six
modes, their divide ratios and an example of the delay time for each mode:

N.B. The TAP DIVIDE button has no effect on delay time when delay is set by
the DELAY knob. Cycling through the different TAP DIVIDE modes ― when delay
time was last set by the DELAY knob ― does not change the delay time.
The last TAP DIVIDE button setting is saved and recalled when power cycling.
TAP DIVIDE SEQUENCE MODE –The 1100-TT contains a little easter egg
called Tap Divide Sequence mode. In this mode, the 1100-TT will automatically
cycle through the six tap divide modes at a rate set by the RATE knob. To use
this mode, do the following:
1. Tap in a delay time. Tap Divide Sequence mode will not work if the
delay time is set by the DELAY knob.
2. Press and hold the TAP DIVIDE button for 2 seconds. After 2
seconds, all of the TAP DIVIDE LEDs will light up briefly, now you
are in sequencer mode. You can release the button.
3. Turn the RATE knob to change the speed of the sequence. You
should see the tap divide LEDs light up in a sequential fashion.
4. You can tap in new delay times to change the delay time range.
5. To exit Tap Divide Sequence mode: hold down the TAP DIVIDE
button for another 2 seconds. All 5 LEDs will light briefly to indicate
you have exited sequence mode. You could also simply turn the
DELAY knob.

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 1100-TT 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 1100-TT’s delay block.
RETURN Jack –Connect this jack to the output of another effects pedal or
chain of effects pedals to insert an effects loop before the 1100-TT’s delay block.
The input impedance presented at the RETURN jack is 2 M.
EFFECTS LOOP –The Deluxe Memory Man 1100-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 Nano POG in the 1100-TT’s effects loop, setting
the Nano 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 1100-TT, 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 1100-TT’s effects
loop. The volume pedal will act as a FEEDBACK control. With the addition of an
expression pedal, you could have two pedals controlling parameters on the 1100-
TT.
To properly use the 1100-TT’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: EHX Expression Pedal, M-Audio

6
EX-P, Moog EP-2, Roland EV-5 or Boss FV-500L. You may also connect a control
voltage on TS plug to this jack. The Control Voltage range must be 0 V to 5 V.
EXPRESSION PEDAL CONTROL –The Deluxe Memory Man 1100-TT allows
external control over five of its parameters: BLEND, modulation RATE,
modulation DEPTH, FEEDBACK and DELAY time. Please see the EXP. PEDAL Jack
section above for suggestions on the type of expression pedals to use. The
pedal will need to have a TRS plug. In addition you may use a control voltage,
with a TS plug. The acceptable CV range is 0 V to 5 V.
Use the EXP. MODE button to choose the knob you want to control with an
expression pedal; repeatedly press and release the EXP. MODE button until the
proper LED lights. After selecting a parameter, its associated knob will now set
the maximum sweep range, which is the toe down position for the expression
pedal. For example, if you want to sweep the full range of the FEEDBACK knob,
you will need to set the FEEDBACK knob to its full clockwise position. The
expression pedal will then sweep from 0% feedback (toe up position) to 100%
feedback (toe down position).
Some expression pedals allow you to dial in the heel position using an extra
range knob on the pedal itself. When using this type of pedal you can set the
range for both heel (using the range knob on the expression pedal) and toe
down (using the selected knob on the 1100-TT). If you use an expression pedal
that does not allow you to dial in the heel position, than heel is always that
particular knob’s minimum setting.
TAP SW Jack –Allows the musician to input the tap tempo from an external
momentary switch. The external switch should be normally open. Upon engaging
the switch, it should create a short circuit between the Tip and Sleeve of the plug
inserted into the TAP SW jack on the 1100-TT. Releasing the switch should open
the circuit between the Tip and Sleeve. The TAP SW jack is connected in parallel
with the TAP FSW on the 1100-TT so they can both work at the same time. A
suggested Momentary Footswitch that has been tested with the 1100-TT is the
Boss FS-5U Momentary Foot Switch.
TAP SW Jack Extra Control –If you are handy with a soldering iron, you may
also make connections on the 1100-TT’s PCB to allow external control of either
the TAP DIVIDE button or the EXP. MODE button by connecting an external
momentary switch between the Ring and Sleeve of the TAP SW jack.
To enable external control of the TAP DIVIDE button, short together the pads of
R139 on the 1100-TT PCB. R139 is labeled TAP DIV SW and is located just above
the 10-Pin IDC header, CN6.
To enable external control of the EXP. MODE button, short together the pads of
R140 on the 1100-TT PCB. R140 is labeled EXP FUNC SW and is located above
the 6-Pin IDC header, CN5.

These external switch connections work in parallel with their associated buttons
on the 1100-TT. If either of the buttons have been enabled for external use, a
TRS plug must be inserted into the TAP SW jack. In this circumstance, if a TS
plug is inserted into the TAP SW jack it will be equivalent to holding down
whichever button has been enabled for external use, without the ability to
release the button.
9V PWR JACK –Connect the output plug of the supplied AC Adaptor into the
9V power jack at the top of the 1100-TT. The 1100-TT’s current requirement is
200mA at 9VDC. The polarity of the power jack is center negative. The maximum
allowable power supply voltage is 10.5 VDC.
FACTORY RESTORE
The Feedback Hold setting, along with the original EXP. MODE and TAP DIVIDE
mode, can be restored to their original factory settings by holding down the EXP.
MODE button during start up.
Press and hold the EXP. MODE button, then apply power to the 1100-TT while
continuing to hold the EXP. MODE button. Once you see all five EXP. MODE LEDs
light up solid, you may release the button. The factory settings have been
restored.
