Note:
To CATV system installer’s (U.S.A.): This reminder is
provided to call the CATV system installer’s attention to
Article 820-40 of the NEC that provides guidelines for
proper grounding and, in particular, specifies that the
cable ground shall be connected as close to the point of
cable entry as practical.
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.
Note:
Please check the copyright laws in your country before recording from records, compact discs, radio, etc.

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
40
50

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 KC-300Pro 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 KC-300Pro 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 KC-300Pro, route all cables down the side of the
back of the KC-300Pro instead of straight down the middle of the back of the
KC-300Pro.
Important Stand and Base Safety Information
Choose the location for your KC-300Pro carefully. If the KC-300Pro 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
KC-300Pro.
Use Indirect Light
Don’t place the KC-300Pro where sunlight or room lighting will be directed toward the
screen. Use soft or indirect lighting.

Glossary of Terms
Attenuation – The decrease in amplitude of a signal.
Auxiliary channel (AUX) – A channel reserved for connecting an external audio and/or video device.
A/V – A/V is an abbreviation for Audio/Visual.
Balanced – A circuit having two sides (conductors) carrying voltages that are symmetrical around a common
reference point, typically ground.
CD+G – A specially formatted disc with additional sub-code (data) that is capable of displaying lyrics on video
screens for Karaoke systems. CD+G stands for Compact Disc + Graphics.
Clipping – Refers to a type of distortion that occurs when an amplifier is driven into an overload condition.
Usually the "clipped" waveform contains an excess of high-frequency energy. The sound becomes hard and
edgy. Hard clipping is the most frequent cause of "burned out" tweeters. Even a low-powered amplifier or
receiver driven into clipping can damage tweeters which would otherwise last virtually forever.
Decibel (dB) – Named after Alexander Graham Bell. We perceive differences in volume level in a logarithmic
manner. Our ears become less sensitive to sound as its intensity increases. Decibels are a logarithmic scale
of relative loudness. A difference of about 1 dB is the minimum perceptible change in volume, 3 dB is a
moderate change in volume, and about 10 dB is an apparent doubling of volume. 0 dB is the threshold of
hearing and 130 dB is the threshold of pain.
Delay – Delay is a facet of the echo process. Delay refers to the amount of time that exists between echoes.
Digital Echo – Digital echo is a synthetically processed sound effect that mimics natural echo. Echo in
general is the “bouncing” of waves back and forth between two surfaces. This effect gives a spacious or
ambient feeling that works great with vocals.
Enhancing – Electronically adjusting the quality and sharpness of an audio signal.
Frequency – The range of human hearing is commonly given as 20-20,000Hz (20Hz-20kHz). One hertz (Hz)
represents one cycle per second, 20Hz represents 20 cycles per second and so on. Lower numbers are lower
frequencies
Gain – To increase in level. The function of a volume control.
Impedance – The total of the resistive and reactive opposition, measured in ohms, that a circuit presents to
the flow of alternating current at a given frequency.
Input Selector – A toggle switcher or auxiliary bus used to select through the available inputs of a given
device.
Line Level – CD players, VCRs, Laserdisc Players etc., are connected in a system at line level, usually with
shielded RCA type interconnects. Line level is before power amplification. In a system with separate pre-amp
and power-amp the pre-amp output is line level. Many surround sound decoders and receivers have line level
outputs as well.
Line Voltage – The voltage level of the main power source to a device.
Midrange – A speaker, (driver), used to reproduce the middle range of frequencies. A midrange is combined
with a woofer for low frequencies and a tweeter for high frequencies to form a complete, full-range system.

Glossary of Terms
Multiplex (MPX) – Multiplex is a type of Karaoke software that has specially formatted left and right channels to
make multiplex features available. To be formatted for multiplex use, a disc must have the vocals coded to the right
channel and the music to the left channel. When you select a multiplex mode, the unit will remove the right channel
(vocals) and split the left channel (music) to both sides.
Mute – A mode that turns off the audio output to the monitor speakers. Used when a microphone is in the same
room as the monitor.
NTSC – National Television Systems Committee. Organization that formulated standards for the NTSC television
system. Now describes the American system of color telecasting which is used mainly in North America, Japan,
and parts of South America.
Out of Phase – When speakers are mounted in reverse polarity, i.e., one speaker is wired +/+ and -/- from the
amp and the other is wired +/- and -/+. Bass response will be very thin due to cancellation.
PAL – Phase Alternate Line. The name of the color television system in which the EV component of burst is
inverted in phase from one line to the next in order to minimize hue errors that may occur in color transmission.
PAL is a European color TV system used mainly in Europe, China, Malaysia, Australia, New Zealand, the Middle
East, and parts of Africa.
Pre-Amplifier – Or Pre-amp is a device that takes a source signal, such as from a turntable, tape deck or CD
player, and passes this signal on to a power-amplifier(s). The pre-amp may have a number of controls such as
source selector switches, balance, volume and possibly tone controls.
Rack Mountable – Rack Mountable refers to the ability to place unit into professional or travel rack cases. Such
cases are great for building complete systems and protect them during transportation. The standard rack size for
MOST cases is 19”.
Repeat – Repeat is facet of the echo process. Repeat refers to the frequency of echoes within a period of time.
Sub-Code – Sub-code is specially coded area of data used by CD+G manufacturers to produce lyrics for Karaoke
video output.
Tweeter – A speaker, (driver), used to reproduce the higher range of frequencies. To form a full-range system, a
tweeter needs to be combined with a woofer, (2-way system), or a woofer and midrange, (3-way system).
VCD – VCD is a disc formatted in MPEG-1. These discs are good candidates for Karaoke use as they have an
audio and a video layer to them. VCD stands for Video Compact Disc.
Vocal Cancel – Vocal Cancel is a feature that removes vocals from multiplex CD tracks. To be multiplexed, a disc
must have the vocals coded to the right channel and the music coded to the left channel. When you select Vocal
Cancel, the unit will remove the right channel (vocals) and split the left channel (music) to both sides.
Vocal Partner – Vocal Partner is a feature that removes vocals from multiplex CD tracks much in the same way as
Vocal Cancel, but with an added “auto-pilot” function. The main difference is that Vocal Partner will only remove
vocals as long as there is activity going through the microphone (singing). When you stop singing, the vocals
automatically return.
Vocal Reducer (Eliminator) – Vocal Reducer is a feature that removes vocals from standard non-multiplex CD
tracks. To do this, the unit compares the audio on the left and right channels, and cancels out any signals that
appear on both. Most currently recorded CD’s contain the vocal layer on both sides, however some may not,
leading to varying results. This feature is also referred as "Vocal Eliminator"
Woofer – A speaker used for low-frequency reproduction, usually larger and heavier than a midrange or tweeter.
Y-Adapter – A type of adapter that splits a signal into two parts. An example would be a connector with one male
RCA jack on one end, and two female RCA jacks on the other end.
