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
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.
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.

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)
toggles whether the unaffected
INPUT signal or the buffered
signal is sent to OUTPUT 1
