ZXY-M372 Clear Sound Audio Isolator Eliminate Current Sound
Interference
1.Product Description
The ZXY-M372 audio isolator's common grounding performs
outstandingly in the field of audio isolation, with significant
advantages. It achieves powerful electrical isolation by separating
different audio circuits, effectively blocking interference,
preventing buzzing, noise, and other noise from mixing into audio
signals, and ensuring signal purity when connecting complex audio
devices. At the same time, it can significantly enhance signal
integrity, reduce distortion risks, and is of great significance
for audio applications that pursue high fidelity. Whether it is
recording fine instrument sounds or broadcasting high-quality audio
content, it can accurately restore the original characteristics of
the sound. The unique public grounding design is specifically
designed to eliminate common ground loop problems in audio systems,
providing independent isolated grounding connections for each audio
channel, improving sound quality while enhancing system stability.
It has a significant effect in multi device interconnection
scenarios such as home theaters. In addition, it has a wide range
of compatibility and can seamlessly collaborate with various
professional or civilian audio equipment, from small home recording
devices to large commercial installations. The product is made of
high-quality materials, sturdy and durable, and can work
continuously and stably in various environments. Whether it is a
damp performance venue or a controllable recording studio, it can
provide reliable audio isolation services for a long time without
frequent replacement or maintenance.
2. What is the common ground?
This product is an audio common ground isolator, effective for
noise caused by common ground between audio source and receiving
equipment.
To put it simply, the common ground is that the ground point of the
two electrical appliances is not at the same point, because of the
difference in grounding resistance, the noise is transmitted
through the ground wire into the electrical equipment, forming
interference. Because the ground points of the two devices are
different, it is possible to produce common ground noise. In the
car audio, there is a kind of audio interference, like whistling,
the frequency of this noise will change with the speed of the
engine.
Therefore, this product can only eliminate the noise and current
sound of common electric and ground products, and can not eliminate
the noise caused by other reasons, so it is necessary to confirm
the source of noise in person.
3. Determine whether the noise is caused by common ground
(1). the use of headphones and car MP3, car navigation AUX (3.5mm
interface) connected, if there is no noise heard from the
headphones at this time, you can confirm that the noise of the car
equipment is caused by common ground.
(2). use the audio line to connect the battery-powered mobile
phone, or MP3(pay attention to the mobile phone, MP3 do not connect
with any power supply in the car, such as the phone) and the AUX of
the car console, and play the music of the mobile phone, so that
there is no noise, you can confirm that the noise in the past is
caused by common ground.
(3). computer, power amplifier, audio, CD: the use of passive
headphones inserted in the computer to listen to no noise, the use
of mobile phones inserted in the power amplifier, audio test, if
there is no noise between the two, the basic judgment is caused by
common ground.
(4). after starting the car, the installed power amplifier has the
current sound, some models will also appear the larger the
throttle, the larger the current sound, this product can solve this
problem.
(5). there is a current sound between the power amplifier and the
speaker or speaker, you can install this product between the power
amplifier and the speaker.
(6). the laptop computer connected to the projector at the same
time to the power amplifier to produce noise, you can connect the
laptop adapter power supply or battery, at this time unplug the
power amplifier noise disappeared, or unplug the projector the same
noise disappeared, then you can add a common ground isolator
between the headset hole and the power amplifier to eliminate
noise.
4.Advantage
Advantage | Description | Application Impact |
Robust Electrical Isolation | Separates different audio circuits, effectively blocking electrical
interference such as hums and buzzes. | In professional recording studios, it ensures that audio signals
from various sources like microphones and instruments remain pure,
free from external electrical noise. This results in high - quality
recordings with minimal background interference. |
Enhanced Signal Integrity | Reduces the risk of signal distortion by isolating audio paths. | For high - fidelity audio applications, whether in a broadcast
station for transmitting clear audio content or in a high - end
home theater system for immersive sound experiences, it preserves
the original characteristics of the audio signal, leading to more
accurate sound reproduction. |
Ground Loop Elimination | Breaks ground loops by providing separate and isolated ground
connections for each audio channel. | In audio setups with multiple interconnected devices, such as in a
home theater where components like TVs, amplifiers, and speakers
are linked, it eliminates the persistent hum caused by ground
loops, improving the overall audio quality and system stability. |
Versatile Compatibility | Can be easily integrated into a wide range of audio systems,
including professional - grade and consumer - level devices. | It is suitable for various applications, from small - scale home
recording setups where it can be used with basic audio interfaces
and microphones to large - scale commercial installations involving
complex audio mixing consoles and multiple speakers. |
Durability and Reliability | Constructed with high - quality materials, capable of withstanding
continuous use in different environments. | Whether in a humid live concert venue or a controlled recording
studio atmosphere, it provides consistent audio isolation over an
extended period. This reliability means less downtime for audio
professionals and enthusiasts due to equipment failure, ensuring
smooth audio operations. |
