comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation.
This equipment generates, uses and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions, may
cause harmful interference to radio
communications. However, there is no guarantee
that interference will not occur in a particular
installation. If this equipment does cause harmful
interference to radio or television reception, which
can be determined by turning the equipment off and
on, the user is encouraged to try to correct the
interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment
and receiver.
Connect the equipment into an outlet on a circuit
different from that to which the receiver is
connected. Consult the dealer or an experienced
radio/TV technician for help.

These buttons are used for adjusting the music scale. Each step is for1/4
tone adjustment, and the middle button is for the original/standard key. After a song finishes,
or the music has been terminated for more than 4 seconds, the system will automatically

C
Congratulation for you choosing
Professional Karaoke Amplifier! This is
an absolutely correct decision. If you
are a singing-lover, you will thoroughly
forget the traditional echo karaoke
Amplifier after experiencing .
is a DSP REVERB work-of-art with
robust and powerful functionalities and
able to make your performance as
elegant and enchanting as professional
singers can reach. Singer’s breathing
or tone-changing can be exactly
visually and acoustically synchronized
and reach an optimized effect. For
Beginners, would be able to lead
you to the most correct and proper
manners and skills for signing.
Has built-in 32bit Hi-Speed
Digital-Process DSP ECHO and
REVERB – Hi-Power-Output TWO
Channel Amplifier. If the space is
sufficient, it is suggested to connect the
Mid-channel of with another
amplifier, and also connect the active
subwoofer. With proper adjustments,
the acoustic range of voice would be
much wider, and the position of human
voice would be much more
Concentrated. It is suggested to get
more advices from experienced
professionals when considering to
purchase microphone and speakers, in
order to obtain the best performances
Of . Especially in an airtight space
(Living room, KTV room…etc), can
easily overcome various acoustic
problems, and grant you a crystal-clear
voice.
Guide for Major Functions on the
Front Panel
1. MIC MASTER / MUSIC VOL
In addition to function as the volume
adjustment for the usage of
microphone and karaoke music, users
can enter the max./min. volume
settings by pressing the OSD button on
the remote control. This function is
designed to avoid the instruments from
Damages resulting from excessive
volume. Besides, the optimized and
fixed volume setting between
background music and microphone is
convenient for users. It needs no extra
adjustments on volume when turning
on the system. With this function, we
can say goodbye to the unnecessary
troubles resulted by miss-hitting the
volume button.
2. SUB
Crossover Point Adjustment for
Subwoofer. The range is between
50Hz ~ 150 Hz. Besides enhancing
the atmosphere and mood, the SUB
function can compensate the
insufficient subwoofer effects on Left /
Right Channels. When we adjust this
function, it would be acceptable when
there is no bass reflection resonance
rumbled in the whole space. It is
suggested to slightly fade the MUSIC
TONE (BASS) of Left/Right Channels.
This can ensure a solider and clearer
performance of subwoofer.
3. Hi-CUT
Eliminate the hiss resulted from
labiodentals and microphone. In some
cases, when we collocate the amplifier
and the microphone, there would be
the protrude Hi-Frequency response
issue, and will lead to the problem of
labiodentals hiss and some feedbacks.
This function can avoid these problems
from occurring. After the proper
adjustment, we can use MIC-TONE
(TREBLE) function to fine-tune and
compensate.
4. MIC LOW CUT
Eliminate the Low-Frequency feedback
of the microphone. Basically, the
Low-Frequency feedback of the
microphone is a problem that most of
the karaoke systems can’t overcome.
This problem comes from the amplifier
locations at different height, and the
reflection of microphone’s nature. This
is the problem that MIC-TONE(BASS)
can’t handle; however, MIC LOW CUT
Function can help to shot this trouble.
