III: Principles of Interference and Noise Generation in Audio Applications
Various audio applications in the environment will inevitably encounter ground loop / ground loop interference: mainly due to the audio cable between the two line segments of the different voltage difference caused by the large audio equipment are scattered between the placement of the audio line between them is connected, between the equipment to generate a different audio signal reference ground potential difference, so signal current loop interference is generated, this phenomenon is often found in the shielding of the equipment and cable Equipment, in the case of longer audio line is easy to produce a higher ground loop voltage, it and the equipment shielding layer will produce a voltage difference between the phenomenon will lead to distortion of the audio signal and produce serious current sound and interference noise, and in serious cases will also lead to the phenomenon of audio equipment burned out.

IV: T100 Audio Isolator Working Principle
This product is to make the input audio source and isolator input alone to form a loop, at the same time the isolator output and the load also form a loop, before and after the level of audio equipment will not form a physical electrical connection between the electrical isolation to ensure that the product uses a low-frequency electrical signals consume a very low magnetic conductivity materials, special coil matching, so the original audio signal without loss, no distortion for mutual coupling transmission. So as to achieve the balance of the signal, inhibit noise blocking interference, optimize the purpose of the audio signal.

V: Audio Isolator Main Functions and Features:
1) Complete physical-electrical isolation between the inputs and outputs of the two channel signals.
2) Flexible switching between inputs and outputs, between various interfaces, and between balanced and unbalanced.
3) Isolates the current sound and noise generated by the system when it is not connected to a common ground.
4) Ensure the safe transmission of signals, because it is isolated, so it can protect the equipment from being damaged by the difference in voltage to ground (such as fire, static electricity, etc.)."

VI: Use of the TM100 Isolator:
This product does not require power supply, just check the corresponding signal line. The input and output do not need to distinguish Left channel and Right channel. You only need to pay attention to the A-terminal input corresponding to the A-terminal output, and the B-terminal input corresponding to the B-terminal output. It is easy and simple to use, safe and reliable. It's must-have item for all kinds of audio occasions and audio lovers.
