Danger
Exposure to extremely high noise levels may cause a permanent
hearing loss. Individuals vary considerably to noise induced hearing
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:
DURATION PER DAY (HOURS)86432 1
SOUND LEVEL (dB) 90 93 95 97 100 103
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 that all persons exposed to
equipment capable of inducing high sound pressure levels, such as this
amplification system, be protected by hearing protectors while this unit is in
operation.

9. Do not defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the 0ther.A
grounding-type plug has two blades and a third grounding prong. The
wide blade or the third prong are provided for your safety If the
provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord being walked on or pinched, particularly at
Plugs, convenience receptacles and the point where they exit from
the apparatus. Do not break the ground pin of the power supply cord.
11 . Only use attachments specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer or sold with the apparatus. When a cart is used, use
caution when moving cart/apparatus combination to avoid injury from
tip-over.
13. Unplug this apparatus during lightning storms or when unused for
long periods of time.
14. Care should be taken so that objects do not fall and liquids are not
spilled into the unit through the ventilation ports or any other
openings.
15. Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way; such as, powersupply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to
rain or moisture, does not operate normally or has been dropped.
16. WARNING: To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.

30 WATT ACOUSTIC GUITAR AMPLIFIERMOSFET
1.) Mic/Line Input - this is a 1/4” 2 conductor input jack for plugging in a Hi-Z microphone or instrument. It is intended for
microphones but will accept other instruments as well.
2.) Guitar Input -
this is a 1/4” 2 conductor input jack for plugging in your instrument. It is intended for guitar or Hi-Z
microphones but will accept other instruments as well.
3.) Mic/Line Volume -
this control is the output volume control for the mic/line input. Slowly increase the control to increase
the volume. If you are using a high impedance microphone, be careful when increasing the volume. Depending on mic
position, it may feedback if mic is in front of speaker.
4.) Mic/Line -
this switch will select a mic or line level input. If you are using a high impedence microphone, be careful when
increasing volume. Depending on mic placement, feedback may occur.
5.) Guitar Volume -
this control is the output volume control for the guitar input. Slowly increase the control to increase the
volume. If you are using a guitar with an on-board preamp, set it’s level for a mid position before increasing this control
otherwise distortion may occur.
6.) Active -
this switch will place a -20db pad in the circuit which will allow use of active on-board electronics from pre-
amplified guitars. This will help keep the signal extremely clean.
7.) Frequency -
this control is a tight Hi-Q cut filter notch with an extremely narrow width. It sweeps between 50Hz & 500Hz
and “fine tunes” the midrange of the acoustic guitar. This helps elimate unwanted “ringing” tones. It is preset to -10db.
8.) Low -
this control is the bass control. It is active and set to boost or cut frequencies at 60 Hz. This will effect the low
frequency signals. Turning it counterclockwise, the low will be rolled off -18db. Clockwise, it will boost +18db. Especially good
for “cleaning up” preset patches or making thin toned guitars sound fuller.
9.) Mid -
this control is the midrange control. It is active and set to boost or cut frequencies 1.5KHz. This will effect the midlow frequency signals. Turning it counterclockwise, the low-mids will be rolled off -12db. Clockwise, it will boost +12db.
Especially good for “cleaning up” guitar overtones.
10.) High -
this is the high frequency tone control. It is active and set to boost or cut frequencies at 5KHz. This will effect the
high frequency signals. Turning it counterclockwise, the highs will be rolled off -18db. Clockwise, it will boost +18db. This will
add or subtract the high end shimmer and clarity.
11.) Reverb Level -
this control adds the spring reverb and mixes it into the main signal buss. Reverberation creates a trail
like effect with the sound. It lets the notes “hang in the air” longer, extending the sound.
12.) Chorus On/Off -
13.) Chorus Level -
14.) Headphone Jack -
this is the switch to turn on and off the chorus circuit.
this is the Speed Control for the chorus circuit
.
this is a 1/4” 3 conductor jack for plugging headphones. It will sum the signal and put the sound in
both ears, thereby creating a pseudo-stereo sound. Volume will be determined by the volume control on the channel you are
on. It will disconnect the internal speaker when plugged in. This will allow quiet practicing.
15.) Jewel Light -
this jewel light lets you know that the amplifier is on.

Suggested Settings
(These settings are general starting points. They are designed
to get you close to the sound you are looking for. If the control is
not shown, then it doesn’t apply to this particular sound. )
Standard Single Input Setup - in this setup your acoustic/electric guitar is plugged into inputs 1.
(Remember, if you are using an active guitar or pre-amplified guitar, press the active switch in. We
also suggest that you turn it’s output level to about mid way up and this will give you a cleaner sound
as well as giving you available headroom for leads.) The tone controls follow both inputs.
Of course, you can adjust the tone controls to any desired sound but in this setup, we suggest these
tone control settings. It will deliver a clear, clean sound that has enough top end clarity to cut through.
Add low and low mid for a beefier presence but be careful as this can “muddy up” the sound. Adjust
the feedback control to eliminate those unwanted “ringing” frequencies.
Adjust the reverb and chorus to suit the music or to your taste.
Standard Dual Input Setup - in this setup two inputs are utilized. Guitar is plugged into guitar
input jack and a Hi-Z microphone is plugged into mic/line Input. Assuming you are also using a
microphone, plug it into the mic/line jack and slowly turn up the mic/line volume control. Balancing the
two types of inputs gives you a much more natural acoustic guitar sound.
You could also plug in any combination of inputs such as: keyboards, microphones or other guitars.
This can also be a basic mini-PA system. It could be used for plugging in a CD player or cassette
decks and a microphone for singing. It can be used for playing over prerecorded tapes with mixing
capabilities.
As mentioned earlier, you can adjust the tone controls to any desired sound but in this setup we
suggest these tone control settings. Of course it depends on the listening environment. It will deliver a
clear, clean sound that has enough top end clarity to let the acoustic sound cut through.
Adjust the reverb and chorus to suit the music or to your taste.
