Footswitch And Status Led; Jacks; 9V Pwr Jack - Electro-Harmonix Memory Boy Operating Instructions

When you control delay time with an expression pedal, the shortest delay time will be
in the toe up position; the longest delay time will be in the toe down position. The
delay knob works in conjunction with the expression pedal to set the maximum delay
time in the toe down position. As you turn the DELAY knob clockwise, the maximum
delay time for the expression pedal will increase. Some expression pedals, such as
the M-Audio EX-P, have a knob on the side of the pedal. This knob can be used to set
the shortest delay time in the toe up position.
FOOTSWICH and STATUS LED – When the status LED is lit, the Memory Boy is in
effect mode, when the LED is off the Memory Boy is in true bypass mode. The
footswitch below the LED toggles between effect and true bypass modes.

- JACKS -

INPUT Jack – Connect the output of your instrument or another effects pedal to the
¼" INPUT jack. The input impedance presented at the input jack is 1 M.
OUTPUT Jack – Connect the output of the Memory Boy to the input of an amplifier
or another effects pedal.
EXP. PEDAL Jack – Allows the user to control the delay time or modulation rate
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:
Moog EP-2, M-Audio EX-P or Roland EV-5. You may also connect a control voltage to
this jack. The Control Voltage range is 0 V to 5 V.
9V PWR JACK – Connect the output plug of the supplied AC Adaptor into the 9V
power jack at the top of the Memory Boy. The Memory Boy requires 45mA at
9VDC. The polarity of the power jack is center negative. There is also an optional 9V
battery clip inside your Memory Boy. Only use alkaline batteries with the Memory
Boy. You should get 3 to 4 hours use out of one battery.
