FiiO IMP XLR4

Power Amplifier Impedance Adapter

• 4.4mm + XLR-4 balanced outputs

• Internal voltage divider circuit

• Gold-plated copper binding posts

• Aluminum alloy housing 

Built for Driving Headphones with Power Amplifiers

High-power amplifiers can directly drive over-ear headphones, but this often comes with the risk of unwanted noise and potential damage to your headphones. This adapter is built to solve exactly that problem. It absorbs excess power while effectively reducing background noise, allowing your amplifier to unleash its massive driving power. This adapter gives you both safety and superior sound quality, letting you enjoy the pure, stunning sound of your headphones driven by a power amplifier and unlock a higher level of audiophile listening experience.

Compatible with mainstream home HiFi power amplifiers including the EA13, LEVEL 1, and AIR AMP.

4.4mm + XLR-4 Dual Balanced Outputs

The IMP XLR-4 features two mainstream balanced output interfaces, 4.4mm and XLR-4. A single adapter supports a wide range of balanced headphones, eliminating the signal loss and additional coloration often caused by adapters.

Internal Voltage Divider Circuit

Featuring an internal voltage-dividing circuit design, this adapter safely handles high-power output from amplifiers. It fully unleashes the amplifier's driving force, unlocking the true potential of high-impedance, low-sensitivity headphones for a wider soundstage and superior sound quality that only a power amplifier can deliver. It also effectively reduces background noise from the amplifier, allowing low-impedance, high-sensitivity headphones to perform without noise interference affecting the listening experience. Supports amplifiers with power output up to 300W.

Gold-Plated Copper Binding Posts

The copper base offers excellent conductivity, minimizing signal loss and distortion, ensuring the amplifier's original sound signature is faithfully delivered to your headphones. The gold plating provides superior chemical stability, resistant to moisture, corrosion, and oxidation, ensuring reliable and stable contact even after frequent plugging and unplugging over long-term use.

All-Aluminum Alloy Housing

The entire unit features a high-density aluminum alloy housing that provides excellent physical shielding, effectively lowering the noise floor caused by electromagnetic interference. It ensures stable operation through efficient heat dissipation and boasts a solid, premium feel with exquisite craftsmanship.
