Basic Connections
Since the BOOMER contains built-in power amplifiers, speakers, DVD/CDG/CD player, USB player, and SD
card player, the BOOMER can be used as a self-contained sound system. However, the BOOMER contains
various audio video outputs to allow the BOOMER to be connected to multiple TV sets, external sound
systems, and/or multiple sound effect devices. The following content demonstrates the procedures for
connecting the BOOMER to the AC outlet and other audio video devices.

PRE-OUT
www.karaoke.at

The insert is a break point in the input channel signal path, It allows the signal to be taken out from this BOOMER,
through an external equipment such as a Limiter,Compressor,Equalizer, Effector,and then back to the BOOMER,
the input jack can be used with ¼ inch phone jack,the signal will be send out through TIP of the ¼ inch phone
jack and back to the BOOMER through RING of the ¼ inch phone jack.
DVD OUTPUT CONNECTIONS
1.Connecting to a Dolby Pro logic amplifier
The BOOMER allows DVD audio output for 5.1 or 7.1 configurations.
With a 5.1 amplifier, you will need six RCA patch cables. Connect the plug from one side of each cable to the
ML, CEN, SL, MR, SW and SR outputs on the BOOMER. Connect the plug from the other side of each cable to
the corresponding ML, CEN, SL, MR, SW and SR inputs on your 5.1 amplifier.
A 7.1 Pro Logic configuration requires 2 additional RCA cables to be connected from the FL and FR outputs of
the BOOMER to your 7.1 Amplifier.
2.Connecting to a TV with component video
Using 3 appropriate component video cables (usually color coded red, blue and green), connect a set of plugs
to the COMPONENT VIDEO OUT jacks (Y-U/Pb-V/Pr) on the BOOMER and plug the other set of plugs to the
COMPONENT VIDEO IN jacks (Y-U/Pb-V/Pr) on your television. On some TVs, the component video input
jacks may be labeled differently (i.e. Pr/Pb/Y or Cr/Cb/Y or R-Y/B-Y/Y etc.). You will need to press the MODE
button on the remote control to toggle between YUV for Component Video, and S-Video. You can only use the
MODE button when there is no disc inserted in the disc tray.

3.Connecting to a DTS receiver/decoder
Using either a RCA-ended COAXIAL cable suited for digital audio use or an OPTICAL cable, connect one
end to the appropriate jack on the BOOMER (COAXIAL or OPTICAL) and the other end to the appropriate jack
(COAXIAL or OPTICAL). If you have both coaxial and optical inputs on your DTS decoder/receiver, it is
recommended to use an optical connection as those cables eliminate the possibility of EMI (electromagnetic
interference). has 5.1 or 7.1 channel RCA inputs, you can use the 5.1 or 7.1 channel output jacks on
the BOOMER.
AV input connections

Microphone/instrument input connections
After completing your main system connections, it is time to get your microphones and instruments connected
and ready for performing. Before you get started with your connections we recommend that you take the
following tips into consideration:
●When connecting instruments, refrain from using low quality or worn cables as they can cause significant
noise and loud pops, posing a threat to the system's speakers.
●Use caution when connecting a chain of multiple effects pedals, as the output voltage may change and
possibly overload the BOOMER input channel.
The BOOMER has one guitar (¼ inch), one keyboard (¼ inch) and two microphone (¼ inch/XLR) inputs.
1.To connect MICROPHONES via ¼ inch mic cables, connect the XLR-end of the cable into the MICROPHONE
until it locks into place and connect the ¼ inch plug into either the MIC 1 or 2 jack on the BOOMER.
2.To connect MICROPHONES via XLR mic cables, attach the XLR “female” end of the cable into the
“male” three prong jack located at the base of your handheld MICROPHONE until it locks into place.
Then connect the XLR “male” jack at the other end of the cable into either of the BALANCED MIC 1 or 2
inputs on the BOOMER rear panel. It should be obvious which sides of your XLR cable are male and
female as there is only one possible connection.
3.To connect a GUITAR, connect a ¼ inch instrument cable from the GUITAR's ¼ inch output to the BOOMER
¼ inch
GUITAR input.
4.To connect a KEYBOARD, connect a ¼ inch instrument cable from the KEYBOARD's ¼ inch output to the
AKJ7809 ¼ inch KEYBOARD input.
Headphones connections
What you will need
General Connections
●Headphones with a ¼-inch connector at the
other end of the cable (not included).

of echo and counter-clockwise to decrease it. Turn the ECHO control fully counter-clockwise to turn the
echo effect off.
●REPEAT- Use this control to adjust the REPEAT setting of the ECHO effect. As REPEAT adjusts the total
number of echo intervals prior to fade-out, the more REPEAT that is applied, the more ECHO intervals will
occur prior to fade-out. Turn control clockwise to INCREASE and counter-clockwise to DECREASE level.
●DELAY - This control adjusts the amount of time between each echo repeat. Turn clockwise to make the
time shorter and counter-clockwise to make the time longer
