HiFi Class High Fidelity 8 Channel Audio Isolator Passive Direct Box 8 Input 8 Output 1U Cabinet

HiFi Class High Fidelity 8 Channel Audio Isolator Passive Direct Box 8 Input 8 Output 1U Cabinet

Description:
After audio signal passes through the audio signal isolator, the potential difference between the two devices can be completely isolated, avoiding hum interference caused by grounding problems, and preventing excessive potential difference from damaging the input stage of the device. It realizes the safe transmission of audio signals, removes the noise generated by the connection of audio equipment, the noise generated by the notebook computer connected to the mixer; removes the noise generated by the electronic musical instrument connected to the mixer; removes the noise generated by the long-distance cable transmission between the equipment and the equipment. Remove the noise caused by the impedance mismatch between the device and the device. Solve the humming caused by the site electricity, wiring, light interference and other reasons. The 8-channel audio signal noise isolator is also suitable for all large-scale outdoor and indoor performances, lightning protection, sound engineering, conferences, entertainment venues, exhibition halls, movie K movie bars, home theaters, KTV karaoke machine systems, CD players, and vehicles music, Bluetooth music, LED large screen interference, recording system and other audio equipment systems are used. It is an essential equipment for audio system cascading to eliminate noise. Almost all audio equipment and equipment can use audio signal noise isolator to isolate and eliminate noise and hum. It can also be used as a passive DI box, supports hot plugging, can eliminate the equipment in the normal power-on working state, plug the XLR cable or 6.35mmTRS head will not produce impact sound; eliminate the damage to the equipment caused by improper operation.

There are many input and output interfaces for 8-channel audio noise isolator. A/B/C/D channel input and output support RCA connector, 6.35mm TRS plug, and balanced XLR cable. Produced with imported components, the sound is more delicate, transparent and fuller, improves the sound, removes digital flavor, removes burrs, and the sound is pure, the low frequency lower limit is below 20Hz, and the sound is better and beautiful. And the system does not have the bottom noise current sound, no hum. Choose our 8-channel audio signal isolator can let you listen to the sound of nature while protecting your audio system equipment.

The following common noise problems can be properly solved:
1. Eliminate pickup to DVR sound, there is a lot of humming current and noise from the beep;
2. Eliminate the current sound when your computer is connected to a projector at the same time, when the LED screen and the amplifier are connected, when the notebook is not connected to the power adapter, and when the projector is unplugged, there will be no current sound.
3. Eliminate when we start the car engine, the car loudspeaker or active subwoofer will produce current sound, murmur and so on, some models will also murmur with the increase of the throttle;
4. Eliminate normal computer connection to headphones, noise from mixer or amplifier audio connection;
5. Eliminate the noise from connecting the mixer when using headphones when the computer is connected to the projection;
6. Eliminate the noise when the notebook is connected to the mixer when using external power supply, and there is no noise when the power supply is unplugged only using the built-in battery;
7.Eliminate the current-sound noise of the audio cable length when the computer is connected to the mixer, but not close to it; Eliminate the current-sound and noise annoyance caused by too long audio cable pulling
8. Eliminate the computer from connecting VGA video and audio to the home projector at the same time. There will be noise. Unplug the VGA cable and there will be no noise.
9. Remove the computer from connecting to the mixer, use batteries normally, and make noise when connecting to the power adapter;
10. Eliminate the computer connection to the mixer, the two are close to normal, far from murmur, the replacement of the audio cable has been improved, use this audio isolator, completely solved!
11.Eliminate the computer connection to the mixer, beware that the mixer + 48V phantom power source burns the computer, and there is no need to be careful when the 8-channel audio isolator is connected in the middle.
12. Eliminate the AUX connection of the car Bluetooth, and use the cigarette lighter to power it at the same time. When playing music, there will be current sound, but as long as the Bluetooth is powered by the mobile power supply, there will be no noise, and this isolator can completely solve the problem.
13. Eliminate the leakage shock between the device and the device and burn another good device, isolate anti-static and lightning protection;
14. Eliminate the sound, murmur and noise generated by simultaneous interpretation equipment, remote video conference broadcasting, audio-visual teaching, stage audio, video broadcasting, TV station relay trucks, equipment and equipment.
