Brand: Dual

The term "Dual 622" typically refers to a pair of 622 series audio transformers used in an audio amplifier or preamplifier circuit. The 622 series is a type of audio transformer that is commonly used to match the impedance of different components in a signal chain. In a dual configuration, these transformers are typically placed at the input or output stages of an amplifier to ensure a consistent magnetic flux that provides a more accurate transmission of audio signals between the devices connected to the amplifier. The "Dual" prefix is used to indicate that there are two transformers included in the configuration, and this configuration can offer better performance in terms of noise reduction, a wider frequency response, and improved dynamic range compared to using a single transformer. Overall, the Dual 622 configuration is a popular choice for audiophiles and engineers who prioritize sound quality and signal integrity in their audio systems.
