New Product EI2401 1:2 Audio Isolation Transformer for Eliminates Noise and Purifies Signals
1.Product Description
Say goodbye to background noise and reshape a pure sound. The new EI2401 audio isolation transformer is the silent guardian of your audio system. It can accurately eliminate buzzing and other noise caused by grounding issues, and optimize signal strength with a 1:2 boost characteristic. Whether you are engaged in recording production or live performances, it can provide you with unprecedented clear and clean sound quality.
1. Noise cancellation and signal purification
Eliminating ground loop noise: This is the most important function. By physically "disconnecting" the electrical connections between devices, the annoying 50/60Hz AC hum caused by the ground potential difference of the devices can be completely eliminated.
Isolate RF interference and digital noise: effectively block RF interference and high-frequency digital noise generated by computers, mobile phones, lighting equipment, etc., ensuring the purity of audio signals.
2. Signal conversion and level management
Step up conversion: As a "step up" transformer, it can double the input signal voltage. For example, increasing the line level signal of+4dBu to a higher level can help drive long-distance cables or meet the higher input level requirements of certain professional equipment.
Balanced and Unbalanced Conversion: It can flexibly convert between balanced and unbalanced audio interfaces, helping to connect audio devices of different standards and solve the problem of interface mismatch.
3. Equipment protection and system security
DC isolation: prevents dangerous DC voltage from being transmitted between devices, effectively protecting your expensive speakers, amplifiers, mixing console input channels, or other precision audio equipment from damage.
Eliminate power hum: By disconnecting the grounding loop, fundamentally solve the systemic hum caused by power issues.
4. Improve sound quality and signal integrity
Improving signal-to-noise ratio: By filtering out background noise, useful audio signals are made more prominent, thereby enhancing the overall signal-to-noise ratio of the system.
Protecting signal dynamic range: While increasing the signal level, it avoids the distortion that may be caused by active amplification circuits and preserves the dynamics and details of the original signal.
