----------------------------------------------------------------------
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

FX-AUDIO - The first mid-range product to feature a tone control circuit
High-quality sound achieved through artwork, pre-amplification circuit using operational amplifiers
Equipped with an active filter for the operational amplifier IC power supply
AC adapter required (sold separately): DC12V/2A DC jack 5.5mm x 2.5mm (center positive)
FX-AUDIO's first mid-range integrated amplifier with tone control function is now available!
[Product Features]
■ High quality sound with artwork
Circuit design and artwork based on our unique know-how achieve low noise and high separation.
■ Pre-amplifier circuit using an operational amplifier
Uses the Texas Instruments audio operational amplifier "NE5532" (DIP socket type).
The sound quality is adjusted before the power amplifier IC, so advanced users can enjoy changing the op-amp to get closer to their preferred sound quality!
■FX-AUDIO - The first mid-range product to feature a tone control circuit
The mid-range model is also equipped with a tone control circuit (negative feedback type), which was highly requested, achieving both convenience and sound quality.
As with the pre-amplifier section, this circuit uses the Texas Instruments audio op-amp "NE5532" (DIP socket type), so you can adjust the sound quality by replacing the op-amp.
■ Active filter installed in the op-amp IC power supply
An active filter is configured in the power supply circuit to the operational amplifier, providing a clean power supply and achieving high sound quality.
■ High sound quality achieved through efficient placement of bulk capacitors
The power supply smoothing capacitor is a large-capacity 8100μF W series from Nippon Chemi-Con Corporation. Combined with a 330μF ELNA RE3 (85°C type) placed right next to the digital amplifier IC "TDA7498", this achieves a smooth, expansive sound quality that does not lose its volume even at high volumes.
■ Carefully selected parts
The input coupling capacitor to the front-stage operational amplifier uses an ELNA audio-grade 85° capacitor, and the digital amplifier IC input coupling capacitor uses a TDK EPCOS film capacitor.
On the output side, the inductors are TDK power inductors, a standard in digital amplifiers, and the output filters are TDK EPCOS film capacitors, which are well-known for their reliability, such as the Arcotronics/AV R82 63V/0.22μF (Made in Italy) metallized film capacitor.
From input to output, we use parts that are renowned for their sound quality and stability, resulting in uncompromising sound.
■Aluminum alloy body
The hairline-finished body and machined front panel create a luxurious and solid presence.
[Notes]
・This product requires a power supply sold separately. A separate AC adapter is required for use.
