Pro Audio Transformers

Made in the UK



Microphone Input

Microphone Input

Transformer designed to interface microphones with the input stage of audio equipment, such as mixing consoles, preamplifiers, or recording devices.

Microphone Bridging

Microphone Bridging

Used in audio applications to connect a microphone to an audio input without heavily loading the microphone's output. It is designed to "bridge" the connection by presenting a high impedance to the microphone while driving the input stage of the connected device effectively.

Line Input

Line Input

Used in audio systems to interface line-level signals with the input stages of amplifiers, mixers, or other equipment. Its primary purpose is to optimise signal transfer, provide electrical isolation, and minimise noise and interference in audio systems.

Line Output

Line Output

Audio transformer used to couple the output stage of an amplifier, mixing console, or other line-level device to the input of another device, while maintaining signal integrity, providing electrical isolation, and optimizing impedance matching.

Moving Coil

Moving Coil

Amplify the low-level signal from a moving coil (MC) phono cartridge used in turntables. MC cartridges are prized for their superior sound quality but produce very low output voltages, typically in the range of 0.2 mV to 0.5 mV, which is much lower than the output of a moving magnet (MM) cartridge. The transformer boosts this signal to a level suitable for standard phono preamplifiers.

Direct Box

Direct Box

A direct box transformer is a key component in a direct injection (DI) box, a device used to connect high-impedance, unbalanced audio sources (like electric guitars, basses, or keyboards) to low-impedance, balanced inputs (like those on mixers or audio interfaces). The transformer inside the DI box performs several critical functions to ensure clean, noise-free audio signal transfer.

Mains Toroidal

Mains Toroidal

Type of transformer that uses a doughnut-shaped core made of magnetic material. Converts mains power to lower voltages, in order to power your audio circuitry.

Inductors

Inductors

Inductors with multiple connection points (taps) along their winding. These taps allow access to different levels of inductance without requiring multiple separate inductors. They are commonly used in audio circuits where variable inductance is needed for filtering, equalization, or other signal-shaping purposes.
