MC406 BUFFER
MC406 BUFFER
DESCRIPTION
• Low noise buffer in a small,
rugged steel housing
• Hi and Lo cut options with
indication LEDs
• Adjustable 0 to +6dB gain slider
• Features a pass-through 9-volt
jack for other effects
CONTROLS
OUTPUT 1 jack sends out
unaffected INPUT signal or
buffered signal
OUTPUT 2 jack sends out
buffered signal
INPUT jack receives
instrument signal
HI CUT switch cuts top end
frequencies of buffered signal
GAIN slider adds up to +6dB of
gain to buffered signal
LO CUT switch cuts bottom end
frequencies of buffered signal
BUFFER switch (INTERNAL)
7
toggles whether the unaffected
INPUT signal or the buffered
signal is sent to OUTPUT 1
POWER
The MC406 BUFFER can be
powered by a Dunlop ECB003
AC adapter (ECB003E in Europe),
a Dunlop DCB10 DC Brick power
supply, or other well regulated
9 volt DC supply with a minimum
of 50 mA current capability, and
a 5.5 X 2.1 mm positive barrel
connector.
BUFFER (INTERNAL) SWITCH
7
•UP—OUTPUT 1 not buffered
(factory setting)
•DOWN —OUTPUT 1 buffered
DIRECTIONS
• Run a cable from your guitar to
the Buffer’s Input jack and run
another cable from the Buffer’s
OUTPUT 2 jack to the next pedal
in your effects chain.
• Optional: Run a cable from
OUTPUT 1 to tuner, separate
effects chain, or second
amp to receive unbuffered
INPUT signal.
• Move GAIN slider to the right
to compensate for signal loss
or add gain.
• To reduce excessive high end
broadband noise, press the HI
CUT switch.
• To reduce excessive low end
feedback noise, press the LO
CUT switch.
• To access (INTERNAL) switch,
remove INPUT and OUTPUT
jacks with wrench or nutdriver
and slide inner casing
from housing.
