READ THIS BEFORE OPERATING YOUR UNIT  
UNIT!: This product, when installed as indicated in the  
instructions contained in this manual, meets FCC  
requirements. Modifications not expressly approved by  
Vocopro may void your authority, granted by the FCC,  
to use this product.  
1. To ensure the finest performance, please read this  
manual carefully. Keep it in a safe place for future reference.  
2. Install your unit in a cool, dry, clean place - away from  
windows, heat sources, and too much vibration, dust,  
moisture or cold. Avoid sources of hum (transformers, v  
motors). To prevent fire or electrical shock, do not expose to  
rain and water.

product MUST be used. Follow all installation  
instructions. Failure to follow instructions could void your  
FCC authorization to use this product in the U.S.A.  
3. Do not operate the unit upside-down.  
3. NOTE: This product has been tested and found to  
comply with the requirements listed in FCC Regulations,  
Part 15 for Class "B" digital devices. Compliance with  
these requirements provides a reasonable level of  
assurances that your use of this product in a residential  
environment will not result in harmful interference with  
other electronic devices. This equipment  
generates/uses radio frequencies and, if not installed  
and used according to the instructions found in the  
owner's manual, may cause interference harmful to the  
operation of other electronic devices. Compliance with  
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:  
4. Never open the cabinet. If a foreign object drops into the  
set, contact your dealer.  
5. Place the unit in a location with adequate air circulation.  
Do not interfere with its proper ventilation; this will cause the  
internal temperature to rise and may result in a failure.  
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.  
8. Be sure to read the "Troubleshooting" section on 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.  
10. To prevent lightning damage, pull out the power cord  
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  
Curtiss Court, La Verne, CA 91750.  
11. The general digital signals may interfere with other  
equipment such as tuners or receivers. Move the system  
farther away from such equipment if interference is  
observed.  
NOTE:  
Please check the copyright laws in your country  
before recording from records, compact discs,  
radio, etc. Recording of copyrighted material may  
infringe copyright laws.  
CAUTION

Listening For A Lifetime  
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of  
your musical enjoyment. Now it’s time to consider how you can maximize the fun and  
excitement your equipment offers. VocoPro and the Electronic Industries Association’s  
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 Association’s 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:

Microphone Operations  
Adjusting the Independent Volume controls  
When there are multiple vocalists present it is common that some will sing louder than others. The volume levels for  
each pair of mic channels can be adjusted independently to create a balanced vocal mix.  
• Mic Volume 1 controls MIC 1 Input (front panel) and MIC 1/B Input (rear panel)  
• Mic Volume 2 controls MIC 2 Input (front panel) and MIC 2/B Input (rear panel)  
• Mic Volume 3 controls MIC 3 Input (front panel) and MIC 3/B Input (rear panel)  
To adjust the independent microphone volumes:  
Turn the volume control clockwise to increase the volume and counter-clockwise to decrease the volume.  
Adjusting the Master Microphone Level  
Once you have balanced the individual mic channels you can use the Mic Master Level control to adjust the overall mic  
level.  
To adjust the Master Microphone Level:  
Turn the volume control clockwise to increase the volume and counter-clockwise to decrease the volume.  
Adjusting the Microphone Pan  
The Pan control on the front panel allows you to balance the microphone vocal output between the left and right chan-  
nels. Adjust the pan until you find the best sounding mix for each situation. In most cases it will be sufficient to set  
the Pan control in the center position.  
Turn the control all the way left to output vocals to the left channel only  
• Set the control to the center position to output vocals evenly between both left and right channels  
Turn the control all the way right to output vocals to the right channel only  
Adjusting the Microphone Tone  
The DA-1055 PRO allows you to adjust the overall Low, Mid and High EQ of the microphone vocals for a more  
professional and clear vocal tone.  
• LOW EQ: Use this control to increase of decrease the amount of “low end” or Bass present in the vocals.  
Too much bass may sound “muddy” or dull. Turn clockwise to increase the low end and counter clockwise to  
decrease the low end.  
• HIGH EQ: Use this control to increase or decrease the amount of “high end” or Treble present in the vocals.  
Too much treble may sound “tinny” and could be the cause of feedback. Turn clockwise to increase the high end  
and counter clockwise to decrease the high end.  
• MID SWEEP: Use this control to determine which Mid Frequency will be present in the mix. Since the  
frequency ranges from the MID SWEEP are from 250 Hz to 6K Hz, this is particularly versatile for vocals,  
and enabling particular characteristics of the singer to be lifted or suppressed.  
• MID EQ: Use this control to increase or decrease the Mid Frequency that is selected by the MID SWEEP  
control.

Operations Cont.  
Using the Digital Echo (microphone only)  
Turning on Echo:  
1. Press the ECHO button on the front panel IN to turn Echo on.  
2. Press the ECHO button OUT to turn Echo off.  
Adjusting the Echo settings:  
The DA-1055 PRO allows you to adjust the Repeat and Delay of the Echo effect.  
Repeat: The interval time between each repeat. Turning this up (clockwise) increases the time between each repeat and  
turning this down (counter-clockwise) decreases the time between each repeat.  
Delay: The length of the overall echo. Turning this up (clockwise) causes the echo to last longer and turning this down  
(counter-clockwise) shortens the overall time of the echo.  
7-Band Equalizer Operations  
Adjusting the 7-Band EQ  
The Dual 7-Band Equalizers allow you to adjust the music tone independently for the left and right channels. Every room is  
different and requires unique EQ settings to produce an optimum sound. Adjust the EQ until you find the desired tone for  
the source music.  
The following is a general idea of how to use each of the bands however there is no “correct” setting as each performance  
situation is unique.  
64 Hz - Fattens up the sub/bass tones or bass “rumble”. Generally this is only necessary when using a subwoofer  
and the low end is more prominent in the mix.  
160 Hz - Controls the mid-range of the bass/low end.  
400 Hz - Controls the mid to low frequencies.  
1 K - Controls the vocal presence, guitars and anything else in the middle frequency range.  
2.5 K - Controls the more percussive, higher pitched sounds such as snare drums as well as the higher aspects of  
the vocal signal.  
6.4 K - Controls the harmonic values of an instrument and is also useful for defining reverb when present.  
16 K - Controls the highest frequency that is audible to the ears and affects the “shininess” in the mix.  
NOTE: The 7-Band Equalizers do not affect microphone output.  
NOTE: Use the LINE OUT RCA jacks to output the equalizer channels independently from the microphone channels.
