【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.
✅ Nakamichi Co., Ltd. was founded in 1948 by Etsuro Nakamichi and is a Japanese consumer electronics brand originating in Japan. Since the 1970s, it has gained popularity by manufacturing everything from high-quality audio cassette decks to design-focused home cinema audio systems, speakers, hi-fi systems, soundbars, and car stereo products.
✅ Nakamichi CL3 certified (UL certified) in-wall and direct-burial oxygen-free copper (OFC) speaker cables are suitable for outdoor, in-wall, and in-ceiling installations and meet fire safety standards for residential and commercial spaces. The robust PVC-filled outer jacket makes them ideal for personal projects, home theaters, commercial audio systems, conference rooms, entertainment venues, and more. Furthermore, their direct-burial capability allows for direct installation into the ground without the need for conduits.
✅ Why invest in OFC (oxygen-free copper) cables? By removing oxygen from inside the cable, the risk of degradation due to oxidation is reduced, maintaining cable durability while preventing a decrease in conductivity. As a result, OFC cables can supply more power to the amplifier, improve efficiency, and reduce the load on the entire electrical system. All of this leads to getting the best sound quality and performance out of your audio equipment. The initial investment may seem a little high, but Nakamichi's CL3 certified OFC cables are highly durable and will lead to cost savings in the long run.
✅ Color-coded insulation on each conductor allows for quick and accurate polarity identification, faithfully reproducing the transmission of audio frequencies and sound waves from the sound source to the speaker. Furthermore, the jacket and insulation are designed to be easily peeled off, making splicing and installation extremely simple and stress-free.
✅ Quick Facts (Key Features): Foot markers (length indicators) allow you to see the used cable length and remaining length at a glance. The UL-certified CL3 grade PVC-filled jacket can withstand voltages up to 300V and offers excellent resistance to compression and bending. The copper wire is certified as 99.9% pure oxygen-free copper (OFC) by the Swiss third-party testing organization SGS (Société Générale de Surveillance). Furthermore, this cable is also suitable for low-voltage applications requiring 2-core stranded cables (such as LED lighting and security alarm systems).
✅ This product comes with a 3-year warranty. The package includes 250-ft (76.21 meters) of 16AWG Nakamichi CL3 grade OFC (oxygen-free copper) 2-core speaker cable, neatly wound on a spool.
