LOSS BUT NEARLY EVERYONE WILL LOSE SOME HEARING IF EXPOSED TO
SUFFICIENTLY INTENSE NOISE FOR A SUFFICIENT TIME.
THE U.S. GOVERNMENT'S OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION
(OSHA) HAS SPECIFIED THE FOLLOWING PERMISSIBLE NOISE LEVEL EXPOSURES:
ACCORDING TO OSHA, ANY EXPOSURE IN THE ABOVE PERMISSIBLE LIMITS COULD
RESULT IN SOME HEARING LOSS. EAR PLUGS OR PROTECTORS IN THE EAR CANAL
OR OVER THE EARS MUST BE WORN WHEN OPERATING THIS AMPLIFICATION
SYSTEM IN ORDER TO PREVENT A PERMANENT HEARING LOSS. IF EXPOSURE IN
EXCESS OF THE LIMITS AS PUT FORTH ABOVE, TO INSURE AGAINST POTENTIALLY
HARMFUL EXPOSURE TO HIGH SOUND PRESSURE LEVELS. IT IS RECOMMENDED

1.) Line Output - this is a 3 cond. XLR output jack for plugging into Lo-Z microphone inputs as found on PA or recording
mixers. It is intended in place of external mics or used as a built in direct box.
2.) CD/Tape Input - this 1/4 3 conductor jack will allow you to plug in a CD player, tape or any other source to practice along
with. It sums the left and right signals into a mono signal. To control the volume of the source, adjust the output volume of the
device.
3.) Guitar Input Jack - this is a 1/4 2 conductor input jack for plugging in your instrument. It is intended for bass but will accept
other instruments as well.
4.) Gain - adjust this clockwise to match the output level of your bass to the preamp input. If you get an over load LED that lights
up you should lower the gain and increase the volume level for the cleanest possible sound.
5.) Overloa LED - this LED will indicate an overload on the preamp..
6.) Volume - this is the volume control of the amplifier. It works in conjunction with the gain control.
7.) Notch - this control is a wide band sweep from 40 to 800 Hz. It is set at -12db to help you fine tune your sound. It is
effective for clearing up unwanted overtones.
Equalizer Section - All controls are active with a center etent which is equivilant of bypass for that ban . Turning
it counterclockwise, will cut the response at the given frequency up to -12 b. Clockwise, it will boost up to +12 b.
8.) 63 - frequency center of 63 Hz. Boost or cut +/- 12db.
9.) 150 - frequency center of 150 Hz. Boost or cut +/- 12db.
10.) 350 - frequency center of 350 Hz. Boost or cut +/- 12db.
11.) 800 - frequency center of 800 Hz. Boost or cut +/- 12db.
12.) 2K - frequency center of 2Kz. Boost or cut +/- 12db.
13.) 5K - frequency center of 5KHz. Boost or cut +/- 12db.
14.) Effects On/Off - this switch engages the digital effects section.
15.) Effects Level - this control adds the digital effects section and mixes it into the main signal buss. Several different
effects are available. 4-Chorus, 2- lange and 2 Echos.
16.) Program Select -this switch will select any of eight different effects. 6-Chorus and 2- lange.
17.) Jewel Light - this jewel light lets you know that the amplifier is on.
18.) Power - this switch turns on and off the AC power to the amp.
Back Panel - (not picture )
Speaker Out - this is a 2 conductor 1/4 speaker output jack. This will disconnect the internal speaker and allow an external
speaker cabinet to be employed. Rating is 8 ohms.
Line Output - this is a 2 conductor 1/4 line output jack. This will allow an external amplifier or mixing board to be supplied with
the signal from this amp.
Effects Loop I/O - these are 2-2 conductor 1/4 jacks. This will allow an external effects device or equalizer to be patched back in before
the power amp section in this amp. One is send and the other is return.
Footswitch Jack - this is a 2 conductor 1/4 jack. This is for hooking up a footswitch to turn on/off the effects section

Suggeste Settings
(These settings are general starting points. They
are esigne to get you close to the soun you are
looking for. If the control is not shown, then it oesnt
apply to this particular soun . )
Alternative Style - this setting is designed for a upper end punch and edge that will cut
through most any sound. This style will work well with pick or fingers and will add a touch
of distortion to the sound as well. Make sure your instruments volume control is up all the
way. Since you are adding volume, you need to be careful with the actual amount of e.q..
you use as it also can add distortion to the sound. The digital effects, designed especially
for bass, can be used with any setting to enhance your tone. Also, you may want to use a
compressor pedal in the signal chain before the amp to give it a smoother sound but still
edgy. As in all the settings above, it is strictly a matter of personal taste in a achieving the
sound you are looking for.....experiment.
Tra itional Electric Bass Setting - in this setting the amplifier will deliver a standard electric
bass sound. Whether you are playing rock, country, blues or gospel, this setting will get you
close. Because of the Active E.Q., you will be able to dial in your personal preferences from
here. If you play with a pick and want less top end attack on the notes, roll off a bit of the
High control. If its deeper bottom your looking for, add more low and low mid. The key is
to experiment to achieve your own personal sound. The digital effects, designed especially
for bass, can be used with any setting to enhance your tone.
Funk Slap Soun s - this style of music needs a good strong attack sound with lots of top
end. Usually a hollowed out middle will produce the extra top end necessary for the punch
needed for this style of music. If you are using a more thumb style, a bit more low end and
volume might be needed for your particular style of playing. Or less if you really hit it hard.
Even though this is a practice or rehearsal level amplifier, it will deliver the punch and clarity
that you require. The digital effects, designed especially for bass, can be used with any
setting to enhance your tone. Chorus and lange are wonderful in filling out your sound.
Remember to try this amp with an additional speaker plugged in. Youll be nicely surprised.
