FOR YOUR RECORDS Please record the model number and serial number below, for easy reference, in case of loss or theft. These numbers are located on the rear panel of the unit. Space is also provided for other relevant information Model Number Serial Number Date of Purchase Place of Purchase 6 Listening for a Lifetime Selecting fine audio equipment such as the unit youve just purchased is only the start of your musical enjoyment. Now its time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Associations 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 Associations 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 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 Rock band concert in front of speakers Gunshot blast, Jet plane Rocket launching pad

PCM stands for Pulse-Code Modulation and it is a direct digital representation of an analog signal . It means the digital signal does not contain any algorithm or implement compression . Why do I hear a strange growling & buzzing noise through the Optical Input?
The strange buzzing noise is what happens when a Dolby audio signal is fed into the KaraokeDual . The audio compression used by Dolby audio signals is incompatible with the KaraokeDual . Change the optical out settings on the TV from Dolby to PCM for correct audio . What is the range of the microphones?
The maximum range is approximately 40ft . What is the operational frequency of the microphones?
The microphones operate in the 2 .4Ghz band . What do I do if the microphones drop out?
The first step is to change the frequency of the mics, refer to Pairing The Microphones for instructions how to do so . The second step would be to change the batteries and move the receiver away from any sources of RF signals like routers and cordless phones that operate in the 2 .4Ghz band . If the problem persists, please call VocoPro at 800-678-5348 . I lost my original power supply, what can I do?
