⚙️ Customizable Design

• Available in custom voltage, current, power ratings, and winding configurations.

• Optional shielding (copper foil or magnetic shell) for enhanced noise suppression in sensitive audio environments.

Working Principle

Un audio toroidal transformer operates on the principle of induction électromagnétique.

• The input audio signal induces a magnetic field in the primary winding.
• This field transfers energy through the toroidal core to the secondary winding.
• The induced current in the secondary winding recreates the audio signal for output, maintaining full electrical isolation.

This process allows the transformer to:

• Isolate circuits and eliminate interference
• Match impedance between devices
• Convert voltage levels as needed
• Preserve the audio signal with clarity and accuracy

Applications

• Audio Amplifiers & Power Amps – for output stage coupling and impedance matching
• Recording Studios & Broadcasting Systems – for clean, isolated signal transfer
• Hi-Fi Audio Equipment – for superior sound purity and depth
• Microphone Preamplifiers – for signal balancing and noise reduction
• 100V Line PA Systems – for long-distance audio transmission with low loss
• Tube Amplifiers (Valve Amps) – for voltage step-up or step-down and signature analog tone shaping
