CONNECTIONS
9V: Use only Morley's 9 VDC 300 milliamp regulated adapter. Center Polarity is negative.
IN: Input jack. Plug instrument into this jack using 1/4" guitar cable.
OUT: Connect amplifier to this jack using a 1/4" guitar cable.
NOTE: You'll find cords fit very tightly into the input/output jacks. The tight fit helps prevent the cord from being accidentally
unplugged. Make sure cords are completely plugged in for best results.
AC ADAPTER
All Morley pedals use Morley's 9VDC 300 milliamp regulated adapter. Center pin polarity is negative. Using a non-
regulated adapter could cause a low frequency hum in your amplifier. Using an adapter with the wrong polarity may damage
the pedal.
BATTERY USE
All Morley pedals are designed to use one 9V battery when not using an adapter. Battery access is on the bottom cover via our
"Quick Clip" Battery door. We suggest you use a good quality alkaline battery. To prolong battery life, unplug your cord
completely from the input jack when not using the pedal. When the pedal is not used for extended periods, remove the battery
from the pedal or replace it every six months to prevent leakage problems.
BATTERY REPLACEMENT
The ABY is a psssive device (meaning it will function without power. The 9V battery or 9V adapter are used only to light the
LED indicators. Since the battery is only used to light the LEDS the battery life is extroardinary. In fact, you can use 9V
batteries that are "dead" from other pedals and you will find they last for many weeks in the ABY.
GROUND LOOP NOISE? Hooking two
amps together via an ABY box can
sometimes create a LOOP ANTENNA
which causes hum (also known as
Ground Loop Hum, 60Hz Hum or 60
Cycle Hum, 50Hz in Europe). This is not
caused by the ABY but by the connection
of two amp grounds via the ABY. If this
does occur, it can be easily corrected.
Visit www.ebtechaudio.com for
information on eliminating Ground Loop
Hum & Noise with our Hum X or outside
North America, the Hum Eliminator.
IMPORTANT: DO NOT USE THE ABY ON A POWERED SPEAKER LINE! YOU WILL DAMAGE
THE ABY, THE AMP AND THE SPEAKER(S).
