Overview
The Triad Magnetics HS-71 is a low-level audio transformer designed for professional analog applications. It features a primary impedance of 5k ohms and a secondary impedance of 20k ohms, with a turns ratio optimized for signal matching. The component operates within a frequency range extending up to 30kHz, ensuring accurate reproduction across the audible spectrum. Constructed with multiple trialloy cases, interleaves, and heavy copper shading rings, it provides superior hum rejection capabilities. The unit utilizes a base-mount installation style with wire leads for secure integration into audio equipment chassis.
Feature Summary
- Hermetically sealed construction meeting MIL-T-27 specifications
- Superior hum rejection through advanced shielding design
- Wide frequency response suitable for high-fidelity audio
- Rigid mounting with welded stainless-steel studs
Applications
- Professional audio mixing consoles
- High-end amplifier input stages
- Signal processing equipment requiring low noise
- Broadcast studio interface circuits
Procurement Notes
Verify the specific datasheet version when ordering, as manufacturer documentation may be hosted by distributors. Confirm that the part number corresponds to the Triad Magnetics HS-71 audio transformer rather than other series components. Ensure compatibility with existing chassis mounting requirements and wiring configurations before finalizing procurement decisions.
Selection Notes
Select this component for applications demanding high isolation and minimal interference in low-level audio signals. The 5k/20k impedance configuration suits specific tube or solid-state preamplifier designs. Consider the hermetic sealing for environments requiring robust protection against moisture and contaminants while maintaining acoustic performance standards.
Part Context
The HS-71 belongs to the Triad Magnetics HS Series, which specializes in low-level audio transformers. This series is characterized by its use of trialloy materials and copper shading rings to achieve exceptional shielding effectiveness. The components are engineered for durability and consistent performance in critical audio signal paths, distinguishing them from general-purpose transformers.
Replacement Considerations
Triad Magnetics HS-52 serves as a related model within the same series offering similar shielding characteristics. Verify impedance matching requirements when substituting, as the HS-52 features different primary and secondary impedance values compared to the HS-71.
