A-56J

Audio Transformers Overview

The Triad Magnetics A-56J is a chassis-mount audio transformer designed for impedance matching applications. It features a primary impedance of 500 ohms and 125/125 ohms, with secondary impedances of 16, 4, and 4 ohms. The unit provides a turns ratio of 5.6:1 and supports a power rating of 100 mW. The frequency response spans from 30 Hz to 15 kHz, ensuring accurate signal transmission within the specified audio band.

Audio Transformers Feature Summary

• Provides precise impedance matching between high-impedance sources and low-impedance loads
• Supports multiple secondary tap configurations for flexible speaker or load connections
• Engineered for stable performance across standard audio frequency ranges

Audio Transformers Applications

• Audio output stage coupling in tube amplifiers
• Impedance bridging between preamplifiers and power stages
• Custom audio equipment design requiring specific impedance ratios

Audio Transformers Procurement Notes

Verify that the required primary and secondary impedance taps match the circuit design specifications. Confirm that the 100 mW power rating is sufficient for the intended application to prevent saturation or distortion. Ensure chassis mounting provisions are available in the enclosure design to accommodate the physical dimensions of the component.

Audio Transformers Selection Notes

Select this component when a fixed 5.6:1 turns ratio is required for impedance transformation. Consider the 100 mW power limit as the maximum continuous handling capacity. Evaluate the 30 Hz to 15 kHz bandwidth against the system's frequency requirements to ensure adequate coverage for the target audio signals without significant attenuation.

Audio Transformers Part Context
