Nobsound High Precision Passive Preamp Volume Controller for HiFi Enthusiasts

As more and more audiophiles find that the performance of standard multimedia speakers fails to meet their demands, they are increasingly opting for professional active monitor speakers. However, this type of speaker typically lacks a volume control, necessitating the use of a pre-amplifier. Active monitor speakers are predominantly placed on desks for near-field listening, which means users must consider the sizable space required for a Hi-Fi pre-amplifier.

Furthermore, different pre-amplifiers may vary in their timbres, often causing a frustrating issue for audiophiles. Recognizing this problem, Nobsound, a renowned audiophile brand, has designed a product to address it. This compact solution takes up minimal space and its clean, silver color complements a variety of usage scenarios.

Notably, the device contains no amplifying circuit, ensuring it does not alter the timbre, while the built-in amplifier in the active speaker is sufficient to power it. With this product, users can enjoy the original, unadulterated timbre and quality of their speakers without the hassle of selecting a suitable pre-amplifier.

The product's key parameters are as follows:

Color: Gold / Black / Silver Input Impedance: 50K Dimensions (WHD): 644298 mm / 2.521.653.86 in Net Weight: 255 g / 0.56 lb

The product package includes: 1× Passive Preamp

This excellent volume controller is designed for active speakers and pure post-power amplifiers. The HiFi version utilizes an ALPS27 potentiometer and CMC807 RCA, ensuring no gain is added – the maximum output remains the same as the input (e.g., 1V in, 1V out). This allows the device to seamlessly integrate with power amplifiers, active speakers, and some monitor devices, delivering lossless sound quality.

The high-precision adjustment is achieved through the incorporation of a Japanese ALPS27 potentiometer, while the lossless transmission is enabled by pure copper, gold-plated RCA connectors. The high-end aesthetic is further enhanced by the full aluminum chassis and knob, crafted using advanced CNC machining technology.

In summary, this passive preamp from Nobsound offers audiophiles a compact and hassle-free solution to control the volume of their active speakers and post-power amplifiers, without compromising the original timbre and sound quality. Its thoughtful design and premium construction make it an excellent choice for discerning music enthusiasts.
