Line Level Attenuator Unit FX-AUDIO- AT-01J

【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. In addition to three gain settings, there is also a pass-through setting. High-quality sound design with meticulous attention to detail Simple setup, no instruction manual required. Robust and unobtrusive compact housing A truly unique and indispensable item! A small, simple attenuator with minimal sound quality degradation. "I like the sound, but it's too powerful and difficult to use!" "When I turn the volume down late at night, gang error becomes noticeable." "I want to reduce the degradation of sound quality due to volume." In response to customer feedback, we have developed a compact, simple attenuator that minimizes sound quality degradation. This is a compact, unobtrusive, fixed-type attenuator with a focus on functionality, easily configurable via DIP switches. Accuracy tolerance: The metal film resistors have an accuracy tolerance of ±1% or less, minimizing any degradation in sound quality. By connecting it to the input side of high-power amplifiers such as the FX-1002J+ and FX502J-S, you can avoid volume settings where gang error is likely to occur even at low volumes. By connecting it to the input side of a pure power amplifier like the FX-501J/FX-1001J and omitting the preamplifier, you can enjoy the straightforward sound quality of the power amplifier alone. Multi-stage attenuators are very expensive, costing tens of thousands of yen even for the cheapest models, but by limiting the gain setting to just three stages, we have made it much more affordable. With PC audio becoming commonplace and the ability to adjust volume on the source side increasing, we have created an attenuator that meets the need for a more affordable option by limiting its features. ▼▼For an even higher-end model with enhanced sound quality, click here▼▼ https://www.amazon.co.jp/dp/B07Y1DZ79D?ref=myi_title_dp [Product Features] ■In addition to three gain settings, there is also a pass-through setting. The unit's DIP switches allow for three levels of gain adjustment (-6/-10/-20dB), as well as pass-through settings. By attenuating the input line-level audio signal, it becomes possible to adjust the volume range of amplifiers connected to the next stage of this unit, or even replace it with a preamplifier. ■ Meticulous design for high sound quality • Accuracy tolerance: Uses metal film resistors with a tolerance of ±1% or less. • High-quality gold-plated feet are used for the DIP switches. • High-quality gold-plated RCA connectors are used for input and output terminals. ■Simple setup, no instruction manual required The settings are printed on the device itself, so you can change them while referring to them. With four settings—PASS/-6/-10/-20dB—it can accommodate a wide range of situations. ■ Robust and unobtrusive compact housing Despite its compact size of 25mm (height) x 40mm (width) x 55mm (depth) (excluding protrusions), the 63g weight gives it a substantial feel in the hand, conveying a sense of premium quality. Furthermore, to ensure it remains inconspicuous and plays a supporting role, the entire casing, including the front and rear panels, has been given a fine sandblasted finish. [Notes] *Please adjust the gain settings with the power to the device connected to the input/output terminals of this unit turned off. *Instructions are not included. Please refer to the settings sheet printed on the device to configure it. For example, to set the level to -20dB: Turn switches 1 and 2 ON, and switches 3 through 6 OFF.
