3030 BASS COMBO
INPUT
— The 3030 is equipped with a standard 1/4” input. The input impedance is approximately 500k ohms, using the
same scaling amp as our larger models, and is the basis for the smoothness of the tonal response, punch and low circuit
noise. Additionally, the precision input scaling preamp contains a 35 Hz, 12 dB/octave high pass filter (more effective
and less intrusive than the more common 6 dB filters) and an “RFI" filter (radio frequency interference) to eliminate
bleed-through from those pesky DJ's and truckers.
INPUT CHANNEL
— The 3030's input channel is constructed using a monolithic FET amplifier for a bold, crisp, fat
sound. The tone is natural and open, lending itself readily to any musical style. The volume control uses "loop feed-
back" style circuitry for wide dynamic range and an exceptionally low noise floor. Whether playing soft or hard, the re-
sponsiveness is punchy and articulate. The bottom end is solid, not muddy or overpowering.
PRESENCE
— This circuit provides a gradual boost in the upper frequency range for better articulation. The enhance-
ment begins at 2k Hz and provides an increase of approximately 10db.
MASTER 3 BAND EQUALIZATION
— The 3030's main equalization is a classic 3-band passive equalization network.
All pass (no band cut) is attained with the controls in the fully clockwise positions, unlike active controls which exhibit a
“flat” setting at the 12 o'clock positions.
POWER SWITCH
— Turns the AC mains power on and off, indicated by green LED above switch.
EFFECTS SEND/RECEIVE JACKS
— The 1/4” send jack provides a nominal –10dB output signal to drive any common
effects processor. This jack can also be used as an unbalanced line output. The 1/4" return jack is used to return the
processed signal back into the amplifier. This jack contains a switch that automatically opens the signal loop when proc-
essing is used. The “mix” control on the effects device is now used to set the balance between the “wet” (processed
only) and the “dry” (unprocessed) signals.
HEADPHONE OUTPUT
— Used to connect standard headphones (8 - 6M ohm). Insertion of a headphone jack shuts
off signal to speaker jacks, allowing private practice or studio work moth a minimum of fuss and bother, not to mention
noise! This output is short circuit protected.
POWER AMPLIFIER
— The 3030 uses an integrated power operational amplifier to drive the 12" speaker. This fully
monolithic design features complete short circuit and thermal protection built right into the silicon die for high reliability
under adverse conditions.
SPEAKER AND CABINET
— The 3030 uses a custom designed l2" speaker perfectly matched to the precision ported
cabinet. Finished in a textured vinyl finish, the cabinet sports a clean, no nonsense look that shows that it is a serious
music-making machine
POWER INLET
— A fixed power inlet cord set is used to connect the AC mains power to the amplifier. Various voltages
and cord sets are available, depending on the destination country. An internal (non-user replaceable) protection fuse is
provided on the main circuit board. The Mains (line) voltage is nominal 115 volts or 230 volts AC (depending on destina-
tion country), +/- 10%. The amplifier will operate on either 50 or 60 Hz.
