( Brand: Electro Sonic Laboratories ), ( Model: ESL-301 ), ( Part Type: Transformer Step Coil ), ( Country/region Of Manufacture: Denmark )
The ESL-301 Coil Transformer from Sonic Laboratories is a high-quality, moving electro step-up transformer designed specifically for use in ESL (Electrostatic Loudspeaker) systems. This transformer is an essential component in these systems, as it allows for the efficient amplification of low-level signals from the preamp to the high-voltage levels required to drive the electrostatic panels.
The ESL-301 features a moving electro design, which provides a smoother and more linear frequency response compared to traditional fixed-core transformers. This design also helps to reduce noise and distortion, resulting in a more accurate and detailed sound reproduction. The transformer is made of high-quality, audiophile-grade materials, including a copper-wire core and a nickel-plated steel housing, ensuring durability and long-term reliability.
The ESL-301 has a maximum input power of 15 watts and a maximum output voltage of 6000V. It has a tapped secondary windings, allowing for easy selection of the appropriate output voltage for your ESL system. Additionally, the transformer has a low-noise design, with a noise level of less than 0.15% at 1 kHz, ensuring that the sound reproduction is crystal-clear and free of unwanted background noise.
In summary, the ESL-301 Coil Transformer from Sonic Laboratories is a high-performance, moving electro step-up transformer designed for use in ESL systems. Its smooth and linear frequency response, low noise level, and high-quality materials make it an excellent choice for audio enthusiasts who demand the best sound quality from their electrostatic loudspeakers.
