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.

POWER

1.) Microphone Input - this is a 3 cond. XLR input jack for plugging in Lo-Z microphones. It is intended for microphones and
has 15V Phantom Power for condensor microphones.

2.) Piezo Input - this is a 1/4” 2 conductor input jack for plugging in your instrument. It is intended for an acoustic/electric guitar
with a piezo-electric pickup.

3.) Active Input - this is a 1/4” 2 conductor input jack for plugging in your instrument and 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.

4.) Gain 1 - this control is the preamp input for the microphone input. Slowly increase the control to increase the volume.

5.) Effect On/Off- this switch will turn the effects for the microphone channel on and off.

6.) Bass - this control is the bass control for the microphone channel. It is passive and set to shelve frequencies at 100 Hz.
Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the low will be rolled off -12db.

7.) Middle - this control is the midrange control for the instrument channeI. It is passive and set to shelve frequencies at
1KHz.Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the middle will be rolled off -12db.

8.) Phase Reversal On/Off- this switch will reverse the phase on pins2&3forthemicrophone to help with feedback or overly
loud bass frequencies from the microphone channel.

9.) Treble - this is the high frequency tone control for the microphone channel. It is passive and set to shelve frequencies at
3KHz. Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the highs will be rolled off -12db.

10.) Gain 2 - this control is the preamp input for the instrument input. Slowly increase this control to increase the volume on
the instrument inputs.

11.) Effects On/Off- this switch will turn the reverb for the instrument channel on and off.

12.) Bass - this control is the bass control. It is passive and set to shelve frequencies at 100 Hz. Turning it fully clockwise, the
signal is unaltered. Turning it counterclockwise, the low will be rolled off -12db.

13.) Treble- this is the high frequency tone control. It is passive and set to shelve frequencies at 3KHz on the instrument
channel. Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the highs will be rolled off -12db.

14.) Feedback On/Off - this switch will engage the Feedback control.

15.) Feedback - this control is a 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.

16.) Master Volume - this is the overall volume level control for the amplifier. To keep distortion at a minimum, we suggest you
turn this up between 1/2 and 2/3, then bring up the individual channels.

17.) Effects On/Off- this switch will turn the digital effects for the entire unit on and off.

18.) Effects Level - this control adds the digital effects and mixes them into the main signal.

19.) Effects Program - this control selects between the different digital effects. Effects include: 4 Reverbs, 1 Delay, 1 Chorus, 2
Chorus & Reverb.

20.) Jewel Light - this jewel light lets you know that the amplifier is on.

21.) Power - this switch turns on and off the AC power to the amp.

Back Panel - (not pictured)

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 two 2-conductor 1/4” jacks. These 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 onboard digital effects.

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 input

2. (Remember, if you are using an active guitar or pre-amplified guitar, select the active input.
We also suggest that you turn its 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 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 deck 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 to suit the music or to your taste.
