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

This is the ultimate product you've always wanted! A compact, simple attenuator with minimal degradation in sound quality. "I love the sound, but it's too powerful and difficult to use!" "I'm bothered by gang errors when I turn down the volume late at night." "I want to reduce the degradation in sound quality caused by volume." In response to customer feedback, we've developed a compact, simple attenuator with minimal degradation in sound quality. This fixed attenuator features a compact, unobtrusive design and is easily configured with a DIP switch. Gold-skin resistors with an accuracy error of less than ±1% minimize sound quality degradation.

By connecting it to the input of a high-power amplifier like the FX-1002J+ or FX502J-S, you can avoid volume settings that are prone to gang errors even at low volumes. By connecting it to the input of a pure power amplifier like the FX-501J/FX-1001J, you can enjoy the pure sound quality of the power amplifier alone, eliminating the need for a preamp. Multi-stage attenuators are typically very expensive, starting at tens of thousands of yen. However, by limiting the gain setting to three, we've achieved a very affordable price.

As PC audio has become more common and volume control at the source is increasingly possible, we've met the need for an attenuator with limited functionality and a more affordable price.

[Product Features] ■Three Gain Settings and Pass-Through Setting The unit's DIP switch allows for three gain settings (-6/-10/-20dB) as well as a pass-through setting. By attenuating the input line-level audio signal, this unit can be used to adjust the volume range of a downstream amplifier or replace a preamplifier.

■High-quality sound design - Gold-plated resistors with an accuracy error of less than ±1% - High-quality gold-plated DIP switches - High-quality gold-plated RCA connectors for input and output terminals

■Simple setup without manuals Settings are printed on the unit, allowing you to easily check them while making adjustments. Four settings—PASS/-6/-10/-20dB—enable a wide range of applications.

■Durable, compact, and unobtrusive housing Despite its compact size (25mm high x 40mm wide x 55mm deep, excluding protrusions)—its weight of 63g gives it a luxurious feel. In addition, to ensure a discreet and unobtrusive design, the entire housing, including the front and rear panels, has a fine sandblasted finish.

[Notes] ※ Gain settings should be performed with the power turned off for any devices connected to the unit's input and output terminals. ※ No instructions are included. Please refer to the settings chart printed on the unit. Example: To set to -20dB, turn switches 1 and 2 ON and switches 3 through 6 OFF.
