EI19 1:1 Audio Isolation Transformer Single Phase Low Frequency Transformer
1.Product Description
EI19 1:1 Audio Isolator Transformer is a specialized electrical
component designed specifically for audio applications. The "EI19"
indicates its core structure, which consists of E - shaped and I -
shaped laminations. This unique core design effectively reduces
magnetic leakage, enhancing the efficiency of magnetic coupling.
With a 1:1 turns ratio, the number of turns in the primary and
secondary windings is equal, meaning it doesn't alter the voltage
level. Its primary function is to provide electrical isolation
between different audio circuits. By separating the primary and
secondary sides, it safeguards audio equipment from electrical
interference, such as ground loops, which can introduce unwanted
noise into the audio signal. In audio systems, whether it's a
professional recording studio setup, a live sound reinforcement
system, or a high - end home audio system, this transformer plays a
crucial role in ensuring the integrity of the audio signal. It
enables the seamless transfer of audio signals while maintaining
high - quality sound reproduction, free from the distortion and
noise that can be caused by electrical issues. Overall, the EI19
1:1 Audio Isolator Transformer is an essential component for
achieving clean and reliable audio performance in various audio -
related applications.

2.Performance Characteristics
1. Highly efficient electrical isolation: The most significant
feature of the EI19 1:1 audio isolation transformer is its
excellent electrical isolation performance. With a 1:1 turns ratio,
it creates an effective electrical isolation barrier between the
primary and secondary audio circuits. This feature effectively
prevents electrical interference caused by ground loops, stray
capacitors and other factors from entering the audio signal, thus
eliminating noises such as hum, AC sound, etc., ensuring the purity
of the audio signal, and providing a stable and reliable electrical
environment for high-fidelity audio systems.
2. Lossless signal transmission: In the process of audio signal
transmission, the transformer can ensure the integrity of the
signal. Due to its well-designed magnetic circuit and winding
structure, it has very little effect on the amplitude and phase of
the audio signal, and can almost realize lossless transmission of
audio signals. Whether it is a deep drum beat at low frequencies or
a crisp string tone at high frequencies, it can be accurately
restored so that the sound output from the audio equipment remains
original and meets the stringent requirements for signal quality in
professional audio applications.
3. Optimized EI-type core structure: EI-type core structure is
adopted, which consists of E-type and I-type silicon steel sheets
laminated together. This structure effectively concentrates the
magnetic field, reduces magnetic leakage and improves magnetic
coupling efficiency. Compared with other core structures, EI type
core has better magnetic performance in the low frequency band,
especially suitable for audio signal transmission and processing,
which helps to improve the overall performance of the transformer
and the quality of audio signal transmission.
4. Good frequency response characteristics: it has wide-band
frequency response characteristics and can cover the full frequency
range of audio signals (usually 20Hz - 20kHz). It maintains stable
performance throughout the entire audio frequency range, achieving
uniform transmission and isolation of audio signals of different
frequencies without frequency distortion or uneven signal
attenuation, ensuring that the audio system presents rich, balanced
sound effects when playing various types of music.
5. Compact size design: The “19” in the model number usually
represents the size specification of the iron core, which presents
a compact volume overall. This compact design makes it easy to
install inside a variety of audio equipment, especially those small
audio equipment with space limitations, such as portable audio
players, small mixers, etc., without taking up too much space,
while at the same time utilizing its powerful audio isolation and
signal transmission functions.
6. High reliability and stability: After strict manufacturing
process and quality testing, it has high reliability and stability.
In the process of long-term use, it can maintain the consistency of
performance, and is not easily affected by temperature, humidity
and other environmental factors, to ensure the continuous and
stable operation of the audio system. This is especially important
for professional audio equipment that needs to work continuously
for a long time, such as broadcasting radio transmission equipment,
concert live sound system, etc..
