FCC regulations does not guarantee that interference  
will not occur in all installations. If this product is found  
to be the source of interference, which can be  
determined by turning the unit "Off" and "On", please try  
to eliminate the problem by using one of the following  
measures:  
6. Do not use force on switches, knobs or cords. When  
moving the unit, first turn the unit off. Then gently  
disconnect the power plug and the cords connecting to  
other equipment. Never pull the cord itself.  
7. Do not attempt to clean the unit with chemical solvents:  
this might damage the finish. Use a clean, dry cloth.

common operating errors before concluding that your  
unit is faulty.  
Relocate either this product or the device that is being  
affected by the interference.  
9. This unit consumes a fair amount of power even when  
the power switch is turned off. We recommend that you  
unplug the power cord from the wall outlet if the unit is  
not going to be used for a long time. This will save  
electricity and help prevent fire hazards. To disconnect  
the cord, pull it out by grasping the plug. Never pull the  
cord itself.  
Use power outlets that are on different branch (circuit  
breaker or fuse) circuits or install AC line filter(s).  
In the case of radio or TV interference, relocate/reorient  
the antenna. If the antenna lead-in is 300-ohm ribbon  
lead, change the lead-in to coaxial type cable.

and remove the antenna cable during an electrical  
storm.  
If these corrective measures do not produce satisfactory  
results, please contact your local retailer authorized to  
distribute Vocopro products. If you can not locate the  
appropriate retailer, please contact Vocopro, 1728

Listening for a Lifetime  
Selecting fine audio equipment such as the unit youʼve just purchased is only the start of your  
musical enjoyment. Now itʼs time to consider how you can maximize the fun and excitement your  
equipment offers. VocoPro and the Electronic Industries Associationʼs Consumer Electronics  
Group want you to get the most out of your equipment by playing it at a safe level. One that lets  
the sound come through loud and clear without annoying blaring or distortion and, most  
importantly, without affecting your sensitive hearing.  
Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of  
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard  
against this by setting your equipment at a safe level BEFORE your hearing adapts.  
To establish a safe level:  
• Start your volume control at a low setting.  
• Slowly increase the sound until you can hear it comfortably and clearly, and without  
distortion.  
Once you have established a comfortable sound level:  
• Set the dial and leave it there.  
• Pay attention to the different levels in various recordings.  
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all,  
we want you listening for a lifetime.  
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since  
hearing damage from loud noise is often undetectable until it is too late, this manufacturer and  
the Electronic Industries Associationʼs Consumer Electronics Group recommend you avoid  
prolonged exposure to excessive noise. This list of sound levels is included for your protection.  
Some common decibel ranges:

Operations  
Customizing Source Music Output  
Using KEY CONTROL  
If a song’s natural musical key is either too high, or too low to be sung comfortably, use the KEY CONTROL  
feature to bring the musical key into range.  
• Press the UP button to raise the key a ½ step  
• Press the DOWN button to lower the key a ½ step  
• Press the NORMAL button to return the key to its natural position  
There is a maximum of 8 steps in either direction (UP/DOWN.) The current setting is displayed in the KEY  
DISPLAY (ex. -2, +3.)  
Using VOCAL CANCEL (Multiplex) and VOCAL ELIMINATOR  
To remove the lead vocals from a disc so a performer can sing along with the musical accompaniment, use  
either the VOCAL CANCEL (Multiplex) or VOCAL ELIMINATOR features.  
VOCAL CANCEL (Multiplex)  
The VOCAL CANCEL feature is only available when playing a multiplex formatted audio track. Multiplex formatted  
tracks have the music recorded to the LEFT channel, and the vocals recorded to the RIGHT channel.  
• Press the MPX/V. ELIM button once to activate VOCAL CANCEL. When activated, the MPX LED will be  
illuminated GREEN.  
VOCAL ELIMINATOR  
The VOCAL ELIMINATOR feature can be used to remove the lead vocals from standard stereo audio tracks*.  
• Press the MPX/V. ELIM button twice to activate VOCAL ELIMINATOR. When activated, the V. ELIM LED will  
be illuminated YELLOW.  
*NOTE: The Vocal Eliminator feature may not work on all audio tracks; may not  
completely remove the lead vocals; or may partially remove other musical elements  
from the track.  
Using the GRAPHIC EQUALIZER  
Use the equalizer to fine tune the musical signal for optimal sound reproduction and emphasis. For example, if  
after applying Key Control, the music signal sounds less “bright,” you could use the graphic equalizer to restore  
the high frequencies. Or, if you wanted to emphasize the bass of a particularly “thin“ sounding track, you use the  
graphic equalizer to enhance the low frequencies.

Operations cont.  
Customizing Microphone Output  
Using the HIGH/MID/LOW Controls  
To adjust the sound of each connected microphone individually, use the HIGH/MID/LOW controls. These  
controls work similar to the graphic equalizer, enabling to for the enhancement/suppression of particular  
frequencies within each microphone channel.  
• Adjust the HIGH control to increase/decrease sibilance.  
• Adjust the MID control to increase/decrease presence.  
• Adjust the LOW control to increase/decrease boom.  
Using ECHO and REVERB Vocal Effects  
Use the effect controls to add a sense of depth and spaciousness to the vocal signal.  
ECHO  
The ECHO effect adds depth to the vocals for a professional sound. To apply ECHO, follow the steps below:  
• Set the MASTER EFFECT control to 5.  
• For each mic channel where echo will be applied, set the EFX control to 5.  
• Set the ECHO LEVEL control to 5.  
• Set the ECHO DELAY and ECHO REPEAT controls to your liking.  
• Set the ECHO LPF (low pass filter) to 5.  
• Continue to make adjustments to the ECHO LEVEL/DELAY/REPEAT/LPF controls untill the ideal echo  
effect is achieved.  
REVERB  
The REVERB effect adds a sense of space to the vocals for a rich and professional sound. To apply REVERB,  
follow the steps below:  
• Set the REVERB control to 3 as a starting point, and then adjust to your liking.  
After you have customized the ECHO and REVERB effects, you can control  
their application with the following controls:  
• LEVEL MASTER control – Controls the overall effects level available to the microphone channels.  
• EFX control – Controls the level of EFX (set by the LEVEL MASTER control)_applied to each microphone  
channel.  
NOTE: The LEVEL MASTER and EFX controls adjust both ECHO and REVERB effects simultaneously.  
Using the COMPRESSOR Feature  
The built-in COMPRESSOR feature automatically reduces very loud microphone signals or “peaks,” preventing  
unfavorable sound levels from damaging your speakers, as well as your ears. When you notice a microphone  
channel’s PEAK indicator lighting repeatedly, or suspect there may be peaks in the microphone signal, use the  
compressor.  
To apply compression, follow the steps below:  
Turn the COMP knob counter-clockwise to increase compression, and clockwise to disable compression.  
During compression, the dB indicator LEDs will illuminate indicating how much  
the signal was compressed; reduced in output strength.
