Warm tips
1.Available in RCA and XLR Versions: Please choose the appropriate version based on your audio setup.
2.Please use high-quality cables with good shielding performance, otherwise there will be noise.
3.With no gain, no any amplification, only control the signal from the audio source to the back-end devices.
4.When the volume knob is turned to the maximum, the signal passes through without attenuation.

Why use a passive preamp?
Many audio sources, such as DACs and CD players, already deliver high output signals. Meanwhile, many active speakers and dedicated power amplifiers have high gain on their own, making an active preamp unnecessary. In such cases, a passive preamp is the ideal choice, as it avoids sound coloration by using no powered transistors.

Features
- Passive Circuitry with No Gain: Engineered without active components or external power supply, the passive preamp eliminates signal coloration caused by transistors. Pure circuitry maintains original audio fidelity with zero distortion.
- Studio-Grade Attenuation Control: Utilizes a quad-gang ALPS potentiometer for ultra-smooth, low-noise volume control, ensuring fluid adjustment without channel imbalance, perfect for fine-tuning in critical listening environments.
- Source-to-Amp Level Optimizer: Resolves level mismatches between digital sources and sensitive amplifiers. Safely attenuates strong signals without compression, preserving dynamic range while preventing overload.
- Pro-Grade Components for Signal Protection: Features gold-plated terminals for oxidation-resistant signal transmission, paired with double-sided ENIG PCB that ensures consistent signal integrity and long-lasting performance.
- Durability Meets Aesthetics: Precision-machined from solid aluminum alloy, the enclosure offers both durability and a clean, modern look. Its compact construction fits neatly into desktop setups or full-sized audio racks.
