Things to keep in mind when installing karaoke
When applying cheap karaoke rooms need attention some problems so
Thursday I: Arranging speakers:
Speakers have many kind of style, power, .., and have impedance 4 ohm, 6 ohm, 8 ohm impedance we must choose ohm speakers & amplifiers accordingly. Therefore, we should choose the amplifier impedance 4 ohm to 8 ohm from.
For example:
We have speakers 150W / 8 ohm, we must choose the power amplifier 200W / 8 ohm or higher (as long as operational amplifier heats up plus on-line transmission capacity should be reduced).
Speakers should suffer 2m from the floor to the bottom of the speaker, the distance between the two speakers is from 2m to 2.5m, speakers slightly tilted down 15 degrees of loudspeaker pole correct polarity must match the amplifier's speaker (if wrong sound without bass).
When fitting a karaoke systems (microphones, amplifiers, speakers, sub), we have the system ground to avoid being shocked or buzzing.
If It is getting more power subwoofer, then we should let the sub floor, placed between two speakers, subwoofers have 2 pick signal path.
A signal is taken from the line out of the amplifier plugged into an open print head line jack shower of subwoofers.
The signal is taken from the station on the amplifier speaker Input trapped in piles of subwoofers (empirical reality we should choose this path). when choosing this route will give full and true bass music signal. I adjusted the crossover of 80Hz-100Hz sub words. Vol calibration to be reasonable to prevent ringing when a microphone placed near the subwoofer.
Second: Align the amplifier
When connecting system is finished. open electricity before we should turn down the microphone Vol, Vol of music and master's Vol. then we adjusted as follows:
B 1: Plug the microphone into the jack, off road Echo total of microphones we adjust that way (remember to position the Echo button in the middle, also known as 12-hour clock).
B 2: I calibrated the buttons Low, Mid, Hi along that line until we find most pleasing. B3: On the road to Echo total (from 10 hours to 12 hours). Low and Hi To button at between 12 hours. But most important is that adjustment and dly RPT button. Empirically, these people are not professional music theater, it should be two buttons RPT & dly at 11 am. And who said we should sing tuning range 11gio dly button to 1h to the number of repetitions faster one too. Try to hear repeated from 1 to 6 times before. B 4: Coordinate language and music Micro. The music we adjust only 70% of micro-known. B 5: For large and small adjustment after adjustment is complete, then we open the system Matser total. Third: The extra attention when adjusting: When we sing see my voice heavy with increased uplink node's midfield, we screw slowly, if increased more or howling suddenly will cause burns speakers. If we want singing puree and spray spray, we increased a little in Hi button on Micro sugar and sugar Echo total. If not thick hear me singing gently rising path button on the Mic Echo and Echo button on the road Low total. Please note 1 to the following points: As we increase the buttons have to twist slowly and howling gently to avoid damaging the speaker. If the system is geared to handle the fastest howling as we dropped a little button on sugar Micro Vol. Or echo button and the button on the microphone lines. Micro fine not also part makes howling sound. Micro mini theater but inexpensive sound unreal and perishable.
