Shure A95UF Line Matching Transformer — Female XLR to 1/4″ Male Plug/Female Jack
A95UF Overview
The Shure A95UF is a passive line matching transformer designed to interface a balanced low-impedance microphone with an unbalanced high-impedance input, solving one of the most common signal chain compatibility challenges in professional and installed audio environments. By handling the impedance conversion internally, the A95UF prevents the high-frequency loss, level loss, and hum or noise pickup that typically result from connecting low-impedance balanced sources directly to high-impedance unbalanced equipment. It is well suited for audio engineers, system integrators, and venue technicians who need a reliable, passive solution for legacy or mixed-impedance signal chains.
The A95UF’s female XLR input and 1/4″ male plug with female jack configuration allows it to integrate directly into existing cable runs without additional adapters or wiring modifications.
Key Features
- Impedance Matching — Converts balanced low-impedance microphone signals to unbalanced high-impedance inputs for compatible signal transfer
- Hum and Noise Rejection — Transformer design prevents hum and noise pickup associated with high-impedance unbalanced equipment
- High-Frequency Preservation — Eliminates the high-frequency loss that occurs when mismatched impedances are connected without proper transformation
- Level Loss Prevention — Maintains signal integrity and proper output level through the impedance conversion
- Female XLR Input — Accepts standard balanced XLR microphone connections directly
- 1/4″ Male Plug with Female Jack — Provides both a male plug output and a female jack for flexible in-line integration
- Passive Design — Requires no external power, making it suitable for any signal chain without additional infrastructure
