Electro-Harmonix DELUXEMMTAP-1100 Instructions

1

WARNING: Your Deluxe Memory Man w/ Tap Tempo 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 DMMTT
does not take batteries. Using the wrong adapter may damage your unit
and void the warranty.

DELUXE MEMORY MAN w/

TAP TEMPO

TAP TEMPO ANALOG DELAY with FX LOOP,

MODULATION and EXPRESSION PEDAL

CONTROL

Congratulations on your purchase of the Electro-Harmonix Deluxe
Memory Man w/ Tap Tempo (DMMTT). The DMMTT is designed with
high quality, new old-stock 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 DMMTT 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 DMMTT 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

2

this button when the DELAY knob controls the delay time will not change the
delay time.

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 DMMTT 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 DMMTT. As you turn the GAIN knob
clockwise, the input gain will increase. The total gain range is -13 dB to +20 dB.
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 DMMTT. Set
the BLEND knob to the full clockwise position for an output that is 100% wet. Set
the Blend knob 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 DMMTT 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 DMMTT 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

3

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
disabled while it remains plugged into the DMMTT. 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 DMMTT 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
DMMTT 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 DMMTT 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 DMMTT 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 DMMTT
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
DMMTT 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 DMMTT. 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.
