Nobsound HIFI Passive Volume XLR Balanced ALPS Low Aluminum Suitable for Recording Studio For Audiophiles VOL-3 Controller Input/Output, 4-Gang

【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】

■ Voltage Compatibility This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).

Many regions use 120V or 220–240V. Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.

■ Plug Type This product uses a Japanese plug (Type A or B). A plug adapter may be required depending on your region.

■ Transformer Requirement (Very Important) A transformer is required for safe use.

A plug adapter only changes the plug shape and DOES NOT convert voltage. Using this product without a transformer may cause serious and irreversible damage.

■ Buyer Responsibility As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.

■ No Return / No Refund Policy We do NOT accept returns or refunds for: ・Voltage mismatch (including 120V and 220–240V environments) ・Use without a transformer ・Plug incompatibility ・Damage caused by improper setup or usage

■ Liability We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.

■ Final Notice Please ensure full understanding of the above before purchasing. Use only under the correct voltage environment. Ultimate signal purity through a power-free design, without any added distortion or noise: This product uses no active components (transistors or operational amplifiers) internally and requires no external power supply, making it a completely passive (power-free) design. Therefore, it is theoretically free from the "sound staining," "distortion," and "thermal noise" that can be caused by power-source circuits. It guides the audio signal output from the DAC or CD player to the subsequent amplifier in its original purity without amplification. Smooth and precise channel balance achieved with high-quality 4-gang ALPS potentiometers: At the heart of volume control is a 4-gang potentiometer manufactured by ALPS, a company renowned for its audio equipment. The 4-gang structure allows for independent and synchronized control of the two channel signals, resulting in extremely minimal left-right channel balance shifts during volume adjustments and maintaining an accurate stereo sound image at any volume level. The operation is smooth and easy to fine-tune. Achieving optimal matching of high-power sources and high-sensitivity amplifiers: When using modern high-power DACs and high-sensitivity power amplifiers, the signal level can be too high, narrowing the amplifier's volume control range and making fine adjustments difficult. By inserting this product, the powerful signal from the source is appropriately attenuated, allowing the power amplifier's volume to be used within an optimal range. This enables more precise and noise-free volume control without compromising the system's wide dynamic range. High-quality components are used throughout the signal path to minimize transmission loss and degradation: From signal input to output, components are carefully selected for their superior sound quality. Corrosion-resistant, low-contact-resistance plated gold plugs are used for the connectors, and the circuit board uses a PCB treated with ENIG (electroless Ni/Au) for long-term reliability. The integrity and purity of the signal are protected at every point it passes through. Aluminum casing with excellent heat dissipation and shielding, and a compact, practical design: The aluminum alloy casing, with its superior heat dissipation and electromagnetic shielding, protects delicate audio signals from external noise interference. Its compact size makes it suitable for use on a desk, and it easily fits into narrow spaces in audio racks. The simple and modern design does not detract from the aesthetics of your system.
