LA2S-PRO Professional Audio Isolator Speaker Phase Meter Digital Processor Audio DI Box with Dual Channel Volume Fader

Description:
- LA2S-PRO dual channel impedance switching pusher volume control audio signal filtering noise purification sound isolator adopts imported isolation cow and exclusive circuit design, with multiple A/B channel input and output interfaces, including RCA lotus socket, 6.35mm/TRS balanced socket XLR balanced XLR mount supports three types of plugs, allowing for symmetrical or asymmetrical connections.

- It has two balanced and unbalanced impedance switches, which can be connected to the back of electronic instruments to match the acoustic impedance. It serves as a high impedance to low impedance matching DI function between the instrument and the audio equipment. There is also a common ground and non common ground switch, and two volume push switches that independently control the output size of two channel audio signals, making it easy to quickly control the volume output size of computer audio output and other devices.

- The frequency response is wide from 20Hz-20kHz, the sound curve is straight, and the lower limit of low frequency can reach below 20Hz. The intensity is strong, and the medium and high frequencies are soft, clear, and transparent, which can effectively remove various noises in the sound, eliminate noise, AC sound, and other equipment in the audio system. Strong radio interference sound, LED large screen lighting interference, lighting interference, interference noise caused by long connecting wires, suitable for all outdoor and indoor performances, lightning protection, audio engineering, conferences, entertainment venues, exhibition halls, movie bars, home theaters, KTV song ordering systems, CD players, car music, Bluetooth music, LED large screen interference, recording systems and a series of audio equipment systems.

- It can also isolate and protect DC impact from burning out power amplifiers, speakers and other equipment, prevent lightning impact, block mixing consoles +48V phantom power from burning out computer audio interfaces, and support hot plug function.

- The LA2S-PRO sound is delicate, transparent, full, and has a clear sense of hierarchy. It can improve the sound, remove digital flavors, and eliminate sound burrs and noise. If you want the system to have no noise, current sound, or buzzing sound, choosing our dual channel audio signal isolator can allow you to hear the sound of Teana while protecting your audio system from being easily burned out. The following common noise problems can be properly solved:
1. Eliminate the noise from the microphone to the DVR audio system, such as loud buzzing current and rattling sound;
2. Eliminate the sound of current when the computer is connected to a projector, LED screen, and amplifier at the same time. If the laptop is not connected to a power adapter and the built-in battery is used, there will still be AC sound, but as long as the high-definition cable of the projector screen is unplugged, there will be no current sound;
3. Eliminate the sound of electric current and noise from the speakers of the car audio system or active subwoofer when we start the car engine. Some car models may also have noise that increases with the throttle;
4. Eliminate the problem of connecting headphones to the computer normally, but connecting to a mixing console or amplifier may cause noise in the audio system;
5. When connecting the computer to the projector, using headphones is normal, but there is noise when connecting to the mixing console;
6. Eliminate the noise caused by the built-in battery of the laptop, but the noise caused by connecting an external power source to the mixing console;  
7. Eliminate current noise when connecting a computer to a mixing console, and eliminate it when the audio cable is long and close; Eliminate the annoyance of current and noise caused by long audio cables;
8. Eliminate noise caused by simultaneously connecting VGA video and audio to a home projector on the computer. Unplug the VGA cable and there will be no noise;
9. Eliminate the noise and current sound emitted by the KTV music ordering system;
10. Eliminate the connection between the computer and the mixing console. It is normal for the two to be close together, but there is noise when they are far apart. The replacement of the audio cable has improved, but it cannot be solved. Using this audio isolator completely solves the problem!
11. Eliminate the connection between the computer and the mixing console. Be careful not to accidentally press the 48V phantom power supply on the mixing console and burn out the computer. There is no LA-2PLUS audio isolator indirectly connected between the mixing console and the computer. Be careful of this issue.
12. When using AUX to connect car Bluetooth, a cigarette lighter is also used for power supply. At this time, there will be a current sound when playing music, but as long as the Bluetooth is powered by a portable power bank, there will be no noise. This isolator can completely solve the problem.
13. To prevent static electricity or leakage between devices from burning out each other, unplug and plug signal lines while powered on to prevent impact and burning out power amplifiers or speakers (the hot plug function is usually done very well);
14. Eliminate the communication sound, noise, and noise generated between simultaneous interpretation equipment, remote video conference directors, e-learning, stage audio, film and television broadcasting, and television station broadcast vehicles.
