CAUTION: Read this before operating your unit  
CAUTION  
The apparatus is not disconnected from the AC power source so long as it is connected to the  
wall outlet, even if the apparatus itself is turned off. To fully insure that the apparatus is indeed  
fully void if residual power, leave unit disconnected from the AC outlet for at least fifteen  
seconds.  
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, motors). To prevent fire or electrical shock,  
do not expose to rain and water.  
3. Do not operate the unit upside-down.  
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.  
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.  
10. To prevent lightning damage, pull out the power cord and remove the antenna cable during an electrical  
storm.  
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.  
12. When positioning your equipment, especially regarding speakers or other accessories, avoid positioning  
them over areas where they can fall and cause injury to yourself and others.

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:  
Level  
Example  
30

Before Getting Started: Things to Consider  
It is very important to read the following instructions prior to starting any installation procedures. Doing so will  
ensure a correct installation and may save you some time as well.  
Protect Against Power Surges  
• Connect all external components before you plug any of their power cords into the wall outlet.  
• Turn off the DA-3600 Pro before you connect or disconnect any cables.  
• Make sure all cables are properly grounded.  
Protect Components from Overheating  
• Don’t block ventilation holes. Arrange any components so that air can circulate freely.  
• Don’t stack components.  
• If you place the DA-3600 Pro on a stand, make sure you allow adequate ventilation.  
Position Cables Properly to Avoid Audio Interference  
• Insert each cable firmly into the designated jack.  
• If you place components above the DA-3600 Pro, route all cables down the side of the  
back of the DA-3600 Pro instead of straight down the middle of the back of the  
DA-3600 Pro.  
Important Stand and Base Safety Information  
Choose the location for your DA-3600 Pro carefully. If the DA-3600 Pro is placed on a stand or base, ensure  
that it is of adequate size and strength to prevent it from being accidentally tipped over, pushed off, or pulled  
off. This could cause personal injury and/or damage to the DA-3600 Pro.

Getting Connected  
Connecting an Amplifier, External Sound System or Mixing Device  
The DA-3600 Pro’s LINE OUT jacks can be used to connect to a second power amplifier, an external sound  
system or mixing device. The type of cable needed for this connection will depend on the type of jacks that are  
available on your external device (cable needs to have RCA plugs on one end for the LINE OUT jacks on the  
DA-3600 Pro). To make connection, connect plugs from one end of the patch cable to the AUDIO IN, LINE IN or  
CH.A-B jacks on your external system device, and connect the RCA plugs from the other side to the LINE OUT  
jacks on the DA-3600 Pro.

Connecting an External Effects Device to the Effect Loop  
To connect an external effects device to the EFFECT LOOP, you will need two stereo RCA patch cables. First,  
you will need to remove the LOOP-BARS connecting the EFFECT LOOP IN & OUT jacks. Be sure to keep the  
LOOP-BARS in a safe place when they are not being used, as they MUST be reconnected to "complete the loop"  
when there is no external effect device connected. After removing the LOOP-BARS, connect a patch cable from  
the OUTPUT jacks of your external effects unit to the EFFECT LOOP IN jacks on the DA-3600 Pro. Connect a  
second patch cable from the INPUT jacks of your external effects unit to the EFFECT LOOP OUT jacks on the  
DA-3600 Pro. When reconnecting the LOOP-BARS to the EFFECT LOOP, connect one LOOP-BAR horizontally  
between the L-OUT & L-IN jacks, and the other LOOP-BAR also horizontally, between the R-OUT & R-IN jacks.

Getting Connected  
Connecting Speakers  
Either using MDP (banana plug) speaker cables or standard speaker wires, connect speakers paying attention to  
correctly match the polarities (+/-). Connect speakers rated no lower that 4-Ohms to the DA-3600 Pro. Please do  
not try to connect more than one speaker per channel, as the load may exceed the amplifiers handling capacity,  
causing it to overload. If using standard speaker wire, unscrew each plastic bind till you are able to see an interior  
hole for speaker wire (easier to locate when viewing from a side angle). Slide the speaker wires into the slots and  
tighten the plastic binds to tighten them in place. Be sure there is no insulation on the speaker wire preventing  
conductivity.

Connecting to a TV or Display Device  
There are 3 ways to get video from the DA-3600 Pro to a TV or display device:  
a) Connect an RCA video cable from the VIDEO OUTPUT jack on the DA-3600 Pro to the VIDEO INPUT jack on  
the TV. Some TV’s will require that you manually switch the TV to the VIDEO INPUT mode. Other TV’s will  
automatically switch to the video mode when they detect a video signal at the video input jack.  
On most TV’s the jack is labeled AUX or VIDEO.  
b) If the TV does not have a VIDEO INPUT jack you may connect that end of the cable to the VIDEO INPUT of a  
VCR and connect the RF OUTPUT of the VCR to the TV ANTENNA INPUT jack.  
c) If there is no VCR present, you will need to use an RF Modulator. To obtain an RF Modulator, check with your  
VocoPro dealer. An RF Modulator can also be purchased from Radio Shack™.

Balancing the Music with the Vocals  
Have you ever been to a musical performance where the music was so loud that you could barely hear the  
singer? Or maybe to a performance where the singer was so loud that the music was drowned out? Those  
situations are created with poor musical balancing. To avoid these situations the DA-3600 Pro has MASTER,  
HIGH, MID and LOW controls for both the music and the microphone levels. If you find that music is too loud,  
simply adjust the MUSIC VOLUME control. Also, keep in mind that HIGH, MID and LOW levels also affect the  
overall "sound" and can be adjusted to correct sound balancing problems. Excessive high frequencies can  
lead to feedback, so be careful when adjusting them.

Advanced Operations  
Balancing a Microphone Channel  
When adjusting Mic levels, it is recommended to do so in this order:  
1. First adjust the MIC VOLUME control to approximately 50%. (Shown on Fig. 1)  
2. Then balance the LOW, MID and HIGH controls to approximately 40-60%. (Shown on Fig. 2)  
3. Start background music with the MUSIC VOLUME set at approximately 50%. (Shown on Fig. 3)  
4. Fine-tune each MIC CHANNEL as necessary till you get a clean balanced mix (MIC channels 2 and 3 are  
controlled together).  
5. Remember to compensate if the background music has striking volume changes. To do this, you can utilize  
the +20dB GAIN PAD. The +20dB Gain Pad toggles between a current volume level and boosted gain  
volume level. This control can be used to immediately go from one volume level to another by a quick push  
of the button.  
6. Once all the settings are complete, do a complete song for complete balancing success.

Using Digital Echo  
The DA-3600 Pro has built in Pro-Echo circuitry that can be applied to the Digital Echo effect. Digital echo  
provides a very spacious feeling to the vocals, however when Pro-Echo is applied, you get a 3-D-like feel with  
stereo enhanced echo positioning. You can adjust the ECHO in several ways. First off, you can adjust the  
overall ECHO applied to the Mic channels via the ECHO VOLUME control. This limits the echo to all 3  
channels together. Once you have your ECHO VOLUME level established, you can control the level of echo  
applied to each MIC channel individually by adjusting the ECHO control on each MIC channel (MIC channels  
2 and 3 are controlled together). After all the echo levels are set, you can start customizing the nature of the  
echo via the HIGH, LOW, DELAY and REPEAT controls. The HIGH (HI.) and LOW (LO.) controls adjust the  
levels of high and low frequencies applied to the echo processed signal. The DELAY control adjusts the  
interval time between each echo, while the REPEAT control adjusts the # of times the echo will repeat prior to  
fading out. To toggle the PRO-ECHO and normal DIGITAL ECHO effects, use the PRO-ECHO/ECHO button.  
Set the PRO-ECHO/ECHO button to its outer position to apply the PRO-ECHO effect and press the PRO-  
ECHO/ECHO button to its inward position to use the normal DIGITAL ECHO. By fine tuning these controls,  
you can achieve the "perfect" echo effect.
