Some Suggested Settings
ROCK:
JAZZ:
COUNTRY:
BRIGHT:
FUNK “POPPING:”
Since so many variables
affect the actual sound of any
system, the following settings are
offered as starting points to help
you find the exact sounds your
playing demands. When using
the B4R, please keep in mind the
following points:
• The Gain control should be
adjusted until the peak LED
flashes on strong signals. (This
level will vary, depending on
your instrument and playing
style.)
• The Master control should be
set to produce the appropriate
output volume level.
• The Graphic EQ can be used
to further fine-tune these basic
suggested setting, to extend
the frequency response of the
cabinet being used, to com-
pensate for room acoustics, or
to act like a “second channel”
B4R Bass Amplifier
Rack Mounting
When mounting the amplifier into a rack, the four bottom feet should be removed to maintain the three rack space height of the ampli-
fier. Be sure to keep the feet and their attachment bolts for future use. If the feet are reinstalled, never use screws which will protrude
farther into the amplifier than the original hardware.
The rack must be a high quality enclosure capable of securely supporting the weight of the amplifier. Tighten the mounting screws
securely through the amplifier’s face plate, into the rack rails. Check the rack and mounting screws occasionally to ensure a continual-
ly safe and secure installation.
