FiiO has officially introduced the IMP XLR-4 Power Amplifier Impedance Adapter, a compact accessory designed to safely connect headphones to high-power Hi-Fi amplifiers. Priced at just $29.65, the adapter addresses common issues associated with driving headphones directly from speaker amplifiers, including excessive output power, background noise, and the potential risk of damaging headphones.
Designed for audiophiles who pair premium headphones with dedicated power amplifiers, the IMP XLR-4 absorbs excess output power while lowering the amplifier’s noise floor. This enables users to take advantage of the amplifier’s driving capability without compromising the safety of their headphones or overall listening experience.
Built for High-Power Amplifiers
The IMP XLR-4 is engineered specifically for use with Hi-Fi power amplifiers and supports popular over-ear headphones such as the FiiO JT7 and FT7, as well as mainstream power amplifiers including the EA13. Its integrated voltage-dividing circuit safely attenuates the amplifier’s output while reducing background noise, making it suitable even for low-impedance, high-sensitivity headphones.
Dual Balanced Headphone Outputs
The FiiO IMP XLR-4 features both 4.4mm balanced and XLR-4 balanced headphone outputs, allowing users to connect a wide range of balanced headphones without relying on additional adapters. This direct connection helps minimise signal loss and unwanted colouration, ensuring a cleaner and more faithful audio signal.
Premium Construction
FiiO has equipped the adapter with gold-plated copper binding posts to ensure excellent electrical conductivity and long-term corrosion resistance. The robust aluminium alloy housing provides effective shielding against electromagnetic interference while also acting as a heatsink to maintain stable operation during extended listening sessions.
