EI35 Audio Isolation Amplified 4 Times Laminated Low Frequency
Power Transformer
1.Product Description
The EI35 Audio Transformer with wire is a specialized component
designed for audio applications. Its name, EI35, indicates the type of its core. The core is constructed with E - shaped and I - shaped laminations,
typically made of high - quality magnetic materials such as silicon
steel. This structure provides a low - reluctance magnetic path, enabling
efficient magnetic coupling. The "35" usually refers to a key dimension of the core, which
impacts the transformer's power - handling capacity and overall
performance.
This transformer comes with wires attached, which simplifies the
installation process in audio circuits. The wires are carefully selected to ensure low resistance and good
conductivity, minimizing signal loss during transmission. In terms of function, the EI35 Audio Transformer plays a crucial
role in audio systems. It can be used for impedance matching, ensuring that the source and
load impedances are optimized for maximum power transfer. This is vital in applications like connecting microphones to pre -
amplifiers or speakers to power amplifiers. Additionally, it provides electrical isolation between different
parts of the audio circuit. This isolation helps to prevent ground loops and reduces electrical
interference, resulting in a cleaner and more stable audio signal. For example, in a professional recording studio, the EI35 Audio
Transformer can be used to isolate the audio equipment from the
electrical mains, reducing the hum and noise that could otherwise
degrade the quality of the recorded audio. Its frequency response is designed to cover the entire audible
frequency range, from 20Hz to 20kHz, allowing it to accurately
reproduce all audio frequencies without significant distortion. Whether it's the deep bass notes in a piece of music or the high -
pitched trebles in a vocal performance, this transformer ensures
that the audio signal is faithfully transmitted and reproduced.
2.Advantage
1. Easy installation: The built-in wires greatly reduce the
difficulty of installation, eliminating the need for users to
purchase adapter wires separately and perform complex connection
operations. For professional audio engineers, building large-scale
audio systems can save a lot of time and effort, and quickly
connect devices; For ordinary audio equipment enthusiasts, it is
also easy to connect transformers to their own audio and other
equipment without worrying about malfunctions caused by improper
wire selection or incorrect connections, significantly improving
installation convenience and efficiency.
2. Ensure signal transmission: Carefully selected wires with low
resistance and good conductivity are crucial for audio signal
transmission. In the process of audio signal transmission, low
resistance can reduce the loss of the signal on the wire, ensuring
that the signal strength is maximally maintained. Good conductivity
can accurately transmit subtle changes in audio signals, from weak
high-frequency details to strong low-frequency vibrations, all of
which can be presented truthfully, effectively avoiding sound
quality degradation caused by signal loss and distortion, allowing
users to hear clearer and more authentic sound.
3. Strong adaptability and compatibility: The wires equipped with
the transformer are specially designed based on their own
performance characteristics, achieving perfect compatibility with
the internal circuit of the transformer. This means that in
different audio application scenarios, whether connecting
microphones and preamplifiers, or speakers and power amplifiers,
stable and efficient signal transmission can be ensured without
problems caused by incompatible wires and equipment, enhancing the
versatility and applicability of transformers in various audio
systems.
4. Reduce interference risk: Appropriate wires can to some extent
reduce the impact of external electromagnetic interference on audio
signals. Its material and shielding design can resist stray
electromagnetic signals in the surrounding environment, prevent
these interferences from mixing into audio signals, further ensure
the purity of audio signals, and provide a more stable and reliable
working environment for audio equipment, especially in places with
complex electromagnetic environments, such as professional
recording studios, performance venues, etc., which has a
significant effect on improving audio quality.
