ADEQUATE POWER RESERVE FOR PLAYING MODERN MUSIC WHICH MAY
REQUIRE OCCASIONAL PEAK POWER. EXTENDED OPERATION AT
ABSOLUTE MAXIMUM POWER IS NOT RECOMMENDED SINCE THIS
COULD DAMAGE THE ASSOCIATED LOUDSPEAKER SYSTEM. PLEASE BE
AWARE THAT MAXIMUM POWER CAN BE OBTAINED WITH VERY LOW
SETTINGS OF THE MASTER VOLUME CONTROLS IF THE INPUT SIGNAL
IS VERY STRONG.

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:
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.

1.) Mic/Line Input Jack 1 - this is a 1/4 2 conductor input jack for plugging in your instrument. It is
intended for keyboards or Hi-Z microphones but ill accept other instruments as ell.
2.) Mic/Line Input Jack 2 - this is a 1/4 2 conductor input jack for plugging in your instrument. It is
intended for keyboards or Hi-Z microphones but ill accept other instruments as ell.
3.) Volume 1 - this control is the output volume control for the Input #1. Slo ly increase the control to
increase the volume. If you are using a keyboard ith a preamp, set its level for a mid position before
increasing this control other ise distortion may occur. Both inputs follo the same tone circuit as the
other input.
4.) Volume 2 - this control is the output volume control for the Input #2. Slo ly increase the control to
increase the volume. If you are using a high impedance microphone, be careful hen increasing the
volume. Depending on mic position, it may feedback if mic is in front of speaker. Both inputs follo the
same tone circuit as the other input.
5.) Low - this control is the bass control. It is active and set to boost or cut frequencies at 55 Hz. This
ill effect the lo frequency signals. Turning it fully clock ise, the signal is boosted 18 db. Turning it
counterclock ise, the lo ill be rolled off -18db. Especially good for cleaning up preset patches or
making thin patches sound fuller.
6.) Lo Mid - this control is the Lo Midrange control. It is active and set to boost or cut frequencies
at 350 Hz. This ill effect the mid-lo frequency signals. Turning it fully clock ise, the signal is boosted
12 db. Turning it counterclock ise, the lo -mids ill be rolled off -12db. Especially good for cleaning
up preset patches.
7.) i Mid - this control is the High Midrange control. It is active and set to boost or cut frequencies
at 2.5KHz. This ill effect the mid-high frequency signals. Turning it fully clock ise, the signal is boosted
12 db. Turning it counterclock ise, the lo -mids ill be rolled off -12db. Increasing this ill add punch
to keyboard patches or vocal presence.
8.) igh - this is the high frequency tone control. It is active and set to boost or cut frequencies at 8KHz.
This ill effect the high frequency signals. Turning it fully clock ise, the signal is boosted 18 db. Turning
it counterclock ise, the lo -mids ill be rolled off -18db. This ill add or subtract the high end shimmer
and clarity.
9.) Reverb Level - (only on the KMA16R). This control adds the spring reverb and mixes it into the
main signal buss. Reverberation creates a trail like effect ith the sound. It lets the notes hang in the
air longer, extending the sound.
10.) eadphone Jack - this is a 1/4 3 conductor jack for plugging headphones. It ill sum the signal
and put the sound in both ears, thereby creating a pseudo-stereo sound. Volume ill be determined
by the volume control on the channel you are on. It ill disconnect the internal speaker hen plugged
in. This ill allo quiet practicing.
11.) Jewel Light - this je el light lets you kno that the amplifier is on.
12.) Power - this s itch turns on and off the AC po er to the amp.
Back Panel - this is a 2 conductor 1/4 speaker output jack. This ill disconnect the internal speaker
and allo an external speaker cabinet to be employed. Rating is 8 ohms.

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 Dual Instrument Setup - in this setup t o keyboards or instruments are
plugged into Inputs 1 & 2. (Remember, if you are using pre-amplified keyboards or a
drum machine, e suggest that you turn their output levels to about mid ay up and this
ill give you a cleaner sound as ell as giving you available headroom for leads.) You
can also plug in any combination of keyboards, microphones or guitars. The t o guitar
setup is especially useful for teaching studios.
Of course, you can adjust the tone controls to any desired sound but in this setup, e
suggest these tone control settings. It ill deliver a clear, clean sound that has enough
top end clarity to cut through. Add lo and lo mid for a beefier presence but be careful
as this can muddy up the sound.
If you have the KMA16R, adjust the reverb to suit the music or to your taste.
Standard Dual Microphone Setup - in this setup t o Hi-Z microphones are
plugged into Inputs 1 & 2. This is a basic mini-PA system. This can be also be used for
plugging in a CD player or cassette decks and a microphone for karaoke, teaching
studios, small public address or even DJ ork. It can be used for singing over prerecorded
tapes ith mixing capabilities.
As mentioned earlier, you can adjust the tone controls to any desired sound but in this
setup, e suggest these tone control settings. Of course it depends on the listening
environment. It ill deliver a clear, clean sound that has enough top end clarity to let the
voices cut through.
If you have the KMA16R, adjust the reverb to suit the music or to your taste. In public
address ork, you usually dont use reverb unless you are singing.
