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 Input - this is a 3 cond XLR input jack for plugging in Lo-Z microphone or keyboard inputs It has +15v Phantom
Power for condenser microphones
2.) Line
Input #2 - this 1/4 2 conductor jack that allows you to plug in a Hi-z mic or keyboard or any line level source It will
also accept guitar level signals as well
3.) Line
Input #3 - this is a 1/4 2 conductor input jack that will also allow you to plug in a Hi-z mic or keyboard or any line level
source It will also accept guitar level signals as well
4.) Volume 1 - this is the level control for Input #1
Slowly increase the control to increase the volume If you are using a keyboard
with a preamp, set its level for a mid position before increasing this control, otherwise distortion may occur Both inputs follow the same
tone circuit as the other input
5.) Effects - this control determines how much signal from Input #1 goes to the effects buss Clockwise sends more signal
to the buss
6.) Volume 2 - this is the level control for Input #2 As above on Volume #1, the same applies
7.) Effects On/Off - this switch determines whether the signal from Input #2 goes to the effects buss The overall level on
the Effects Level control determines the effects level on that input
.) Volume 3 - this is the level control for Input #3 As above on Volume #1, the same applies
9.) Effects On/Off - this switch determines whether the signal from Input #3 goes to the effects buss The overall level on
the Effects Level control determines the effects level on that input
10.) Low - this control is the bass control for the amplifier It is active and is set to boost or cut frequencies at 100Hz Turning
it fully clockwise, the signal is boosted +12db Turning it counterclockwise, the low will be rolled off -12db
11.) Lo-Mid - this control is the lower midrange control for the amplifier It is active and set to boost or cut frequencies at
500Hz Turning it fully clockwise, the signal is boosted +12db Turning it counterclockwise, the low will be rolled off -12db
12.) Hi-Mid - this control is the upper midrange control for the amplifier It is active and set to boost or cut frequencies at
1 5KHz Turning it fully clockwise, the signal is boosted +12db Turning it counterclockwise, the low will be rolled off -12db
13.) High - this control is the high frequency control for the amplifier It is active and set to boost or cut frequencies at 5KHz
Turning it fully clockwise, the signal is boosted +12db Turning it counterclockwise, the low will be rolled off -12db
14.) Master Volume - this is the Master Volume control for the entire amplifier
15.) Effects On/Off - this switch engages the digital effects section
16.) Effects Level - this control adds the digital effects section and mixes it into the main signal buss Several different
effects are available
17.) Program Select - this switch will select any of eight different effects 4- Reverbs, 2- Echos, 1-Chorus and 1-Chorus/Reverb
1 .) Jewel Light - this jewel light lets you know that the amplifier is on
19.) 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 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 3 conductor 1/4 jack This is for hooking up a footswitch to turn on/off the effects section

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 doesnt
apply to this particular sound. )
Standard Dual Instrument Setup - in this setup one, two or three keyboards or
instruments are plugged into Inputs 1, 2 & 3 (Remember, if you are using pre-amplified
keyboards or a drum machine, we suggest that you turn their output levels to about mid
way up and this will give you a cleaner sound as well as giving you available headroom
for leads ) You can also plug in any combination of keyboards, microphones or guitars
The multi-instrument setup is especially useful for teaching studios
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 Effects section to suit the music or to your taste
Standard Dual/Triple Microphone Setup - in this setup Lo-Z and two Hi-Z microphones
are plugged into Inputs 1, 2 &3 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 work It can be used for singing 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
voices cut through
Adjust the Effects section to suit the music or to your taste In public address work, you
usually dont use Chorus or Delay unless you are singing
