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.
2. IMPORTANT: When connecting this product to
accessories and/or another product use only high
quality shielded cables. Cable(s) supplied with this
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.
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.
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.
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.

Please check the copyright laws in your country
before recording from records, compact discs,
radio, etc. Recording of copyrighted material may
infringe copyright laws.

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
s Consumer Electronics Group recommend you
and the Electronic Industries Association�
avoid prolonged exposure to excessive noise. This list of sound levels is included for your
protection.
Some common decibel ranges:
Level
30
40
50
60
70
80
Example
Quiet library, Soft whispers
Living room, Refrigerator, Bedroom away from traffic
Light traffic, Normal Conversation
Air Conditioner at 20 ft., Sewing machine
Vacuum cleaner, Hair dryer, Noisy Restaurant
Average city traffic, Garbage disposals, Alarm clock at 2 ft.
The following noises can be dangerous under constant exposure:
Level
90
100
120
140
180
Example
Subway, Motorcycle, Truck traffic, Lawn Mower
Garbage truck, Chainsaw, Pneumatics drill

Getting Connected (continued)
Connecting TVs/Monitors to the DA-8909RV
The DA-8909RV has three VIDEO OUTPUT jacks which send video and/or decoded CD+G graphics patched
from your players to TVs and other video monitor devices. This enables multiple TV configurations for
performers to enjoy and KJs and VJs to program a set.
1. Connect RCA style video cables from VIDEO OUTPUT jacks 1, 2 and 3 on the DA-8909RV to the VIDEO
INPUT jack on your TV or other monitor. You may need to manually switch your TV to video mode, while
some models automatically switch when a video signal is detected. On most TVs, the INPUT jack is labeled
AUX or VIDEO.
• If the TV does not have a VIDEO IN jack, you may be able to connect the video cable to
the VIDEO INPUT of a VCR or DVD player and connect the RF OUTPUT on the VCR or DVD
player to the TV ANTENNA INPUT jack.
• If you do not have a VCR or DVD player, you will need to use an RF Modulator to make the
adaption between jacks. RF Modulators are easy to find in the electronics section of many
stores.

1. INPUT SELECTOR - These 4 buttons allow you to select between DVD, AUX, CDG and standard CD
player output to the DA-8909RV. This allows the DA-8909RV to differentiate between all the related
source AUDIO INPUT options available on the back panel.
2. KEY CONTROL - You can adjust the key of your source music in half-step
increments to match the natural range of your voice using the KEY CONTROL
buttons. To flat (b) or lower the key, press the left KEY CONTROL button. To
sharp (#) or raise the key, press the right button. To return to the original key
of the music input source, press the center button. You will see the DIGITAL KEY
DISPLAY reflect the number of steps you have increased or decreased displayed
as numerals with +/-, or 0 for the original key.
�������������������
�������������������
3. LED METER - The LED METER displays stereo output levels for the DA-2808VE mix. The optimal level for
a clean, undistorted signal at high output is to show only occasional peaking in the red LED range. Lower
the MUSIC VOLUME and MIC MASTER VOLUME if red LEDs are frequent.
4. REMOTE SENSOR - When operating the DA-8909RV with the Remote Control, direct the Remote
towards this SENSOR within 23 feet. Maintain a line of sight between Remote and REMOTE SENSOR clear
of obstacles to prevent signal deflection.
5. MIC MASTER VOLUME - This control adjusts the mixed output level for MIC 1, MIC 2 and MIC 3. Turn
clockwise to increase and counter-clockwise to decrease the MIC VOLUME.
6. MUSIC VOLUME - This control adjusts the output level for whichever player connected to an AUDIO
INPUT is assigned with the INPUT SELECTOR.

7. SPEAKERS A/B - These buttons switch between 2 sets of SPEAKER OUTPUT.
8. LED GAIN - Select between a HIGH or FLAT LED display mode for different effect and visibility.
9. VOCAL CANCEL/VOCAL PARTNER - With Multiplex media, lead vocals and music are recorded in separate left
and right stereo channels. When VOCAL CANCEL is selected, the LED will illuminate and the lead vocal channel will
be removed, leaving only a duplicated instrumental track to left and right. When VOCAL PARTNER is pressed, LED
will illuminate and the vocal track will only be activated while there is no microphone input. In other words, while the
Karaoke singer is performing, the vocals will never drop entirely out, keeping the action going.
VOCAL ENHANCER - Because the DA-8909RV allows you to “TUNE” the frequency and mix, or “PROCESS” of your microphone output, it is a more powerful EQ tool than standard Bass and Treble controls.
10. VOCAL ENHANCER ON/OFF - This button activates or deactivates the VOCAL ENHANCER processor feature.
Try using this button to do an A/B comparison of a processed and unprocessed signal while someone sings into the
microphone. This is helpful for fine-tuning and system diagnostics.
11. HIGH - Similar to a Treble control, this boosts the HIGH frequencies in your EQ, from 0 to 10.
12. PROCESS - This control is similar to a Balance control for the EQ, where you can select between a mix predominantly “High end” mix and a bassier “Low end” mix.
13. TUNE - This control allows you fine tune specific frequencies more precisely, by setting the lower cutoff frequency
of the high-pass filter between 1kHz and 8kHz. Fortunately, you can still use it without understanding what that
means. The best way to use this control is by adjusting it while someone is singing into the microphone to find that
“sweet spot” where the EQ sounds clean (not harsh, without distortion) and well-balanced.
14. LOW - Similar to a Bass control, this boosts the LOW frequencies in your EQ, from 0 to 10.
15. LOUDNESS ON/OFF - For an instant Volume/Gain, the LOUDNESS button is an easy way to improve your mix when

12. AUDIO INPUT - Use these inputs for connecting CD, CDG, AUX, DVD or other players and other music
sources using RCA cables. The labels here are for reference only. So, you can connect a cassette player
to the AUX input, for example, and get the same results.
13. PRE OUTPUT - These jacks are designed for connection to external power amplifiers. Output signals
from the PRE OUTPUT are sent before the DA-8909RV amplification stage. This allows you to power your
speaker system from a separate amplifier rather than the speaker output from the DA-8909RV.
14. EFFFECT LOOP - These jacks are necessary to carry the stereo signal for the DA-8909RV’s internal
effects to left and right channel output. The 2 Loop Bars which are already installed in the EFFECT LOOP
IN and OUT jacks of the DA-880VE allow the EFFECT LOOP to operate internally. However, if you wish to
bypass the internal effects, these jacks enable you to connect external effects devices to the DA-8909RV
in a stereo loop.
If you prefer to connect external effects, use RCA cables to connect from the EFFECT LOOP OUT jack
pictured here to your external effect unit EFFECT LOOP input, and then out from the component to the
EFFECT LOOP IN of the DA-8909RV. This creates a continuous stereo loop.
15. SPEAKERS OUTPUT A & B - You can connect up to 4 different speakers between SPEAKERS OUTPUT
A and B. Use ‘banana plug” style speaker cables for left and right of each pair. These can be powered
simultaneously or in individual pairs using the SPEAKERS A/B buttons on the front panel (#7).
16. AC POWER CABLE TERMINAL - Connect the included AC Power Cable here and the other end to an
electrical outlet.
17. FUSE - This plastic cover is the housing for the DA-880VE’s fuse. Use only FUSE type AC 6.3A, 250V
when replacing the fuse.

Remote Control Descriptions and Functions
The maximum operating distance between the Remote Control and the REMOTE SENSOR is approximately 23 feet. If the effective distance of the Remote decreases, replace the batteries. To install new
batteries, remove the battery compartment lid on the back of the Remote and insert two AAA batteries with polarities aligned.
�������
1. POWER - This remote control button turns the DA8909RV ON/OFF
2. INPUT SELECTOR - These buttons switch between the
signals from CD, CDG, AUX and DVD inputs. Whicever
player or source music is connected to these respective
AUDIO INPUTS will be activated with these keys.
3. MIC VOLUME - Use the  to raise the MIC MASTER
VOLUME (front panel, #5) and the  to lower this mixed
MIC MASTER VOLUME. You will see the controls on the
DA-8909RV move as you make adjustments using the
remote keys.

4. MUSIC VOLUME - Use the  to raise the MUSIC VOLUME
(front panel, #6) and the  to lower the MUSIC VOLUME.
You will see the controls on the DA-8909RV move as you
make adjustments using the remote keys.
5. VOCAL CANCEL/VOCAL PARTNER - With Multiplex
media, lead vocals and music are recorded in separate left and right stereo channels. When the VOCAL
CANCEL (VOC/C) button on the remote is selected, the LED will illuminate and the lead vocal channel
will be removed, leaving a duplicated instrumental track to left and right only. When VOCAL PARTNER
(VOC/P) is pressed, the LED will illuminate and the vocal track will only be activated only while there is
no microphone input. In other words, while the Karaoke singer is performing, the vocals will never drop
entirely out, keeping the action going.
6. DIGITAL KEY CONTROL - You can adjust the key of your source music in half-step increments to match
the natural range of your voice using the KEY CONTROL buttons on the remote control. To flat (b) or
lower the key, press the left KEY CONTROL button. To sharp (#) or raise the key, press the right button.
To return to the original key of the music input source, press the center button. You will see the DIGITAL
KEY DISPLAY reflect the number of steps you have increased or decreased displayed as numerals with
+/-, or 0 for the original key.

Advanced Operations
Working with vocals using external effects devices
Often, vocalists use external effects such as Echo, Reverb and Key Control. While enhancing vocals, these
effects can also limit the signal’s sound quality. The DA-8909RV’s Vocal Enhancer can help “clean up” the
vocal signal after effects have been applied.
The frequency bandwidth of most vocals is approximately 300Hz - 6kHz. The DA-8909RV can improve the
sound quality of frequencies across this range so that microphone input has a more natural and clean
sound. Nuances of your vocals can be emphasized without affecting the overall sound. Since every voice
is different, we recommend that you experiment with different settings to find the sound which best suits
your preferences.

Use of the Vocal Enhancer will increase your speaker system’s acoustic performance and its audible
level in a room. This is particularly effective in environments with difficult acoustics. When using the DA8909RV’s Vocal Enhancer, MIC MASTER VOLUME level may need to be adjusted as perceived
volume increases.
1. Connect a microphone with a 1/4” cable to MIC INPUT 1, 2 or 3.
2. Select the VOCAL ENHANCER to the ON (in) position.
3. Start with the HIGH, PROCESS, TUNE and LOW controls at their center positions.
4. Adjust the HIGH and LOW clockwise or counterclockwise until you find a comfortable balance where
they are both equally audible while neither is causing feedback or distortion of the signal.
5. Now adjust the TUNE controls until you reach the desired cutoff frequency for the high-pass filter.
Ultimately, you should be able to settle on a “sweet spot” frequency setting that improves the overall tone
of your treble and bass without leaving either sounding harsh or dominant in the mix.
6. For further fine tuning, think of the PROCESS control as an overall balance between HIGH, or treble
(TOP) and LOW, or bass (BOTTOM). This is a largely a matter of preference, so you should experiment to
find the PROCESS setting that best suits your ears.
7. Try an ON/OFF comparison with the VOCAL ENHANCER to get a better idea for how it is improving your
tone and to better acquaint yourself with the result of adjusting the controls .
