B2/B2R Bass Amplifier
The setting of the Gain control depends on your particular instrument. The
Master should be set to produce the appropriate output volume level. The
Graphic EQ can be used to tailor the amplifier to your speaker cabinets, to
compensate for room acoustics and to “fine tune” your sound.
When mounting the B2R into a rack, the four bottom feet should be removed to maintain the two rack space height of the amplifier. 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.
