【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 - First mid-range product equipped with tone control circuit
High quality sound with artwork, front stage amplification circuit with operational amplifier
Equipped with an active filter in the operational amplifier IC power supply
AC adapter required (sold separately) DC12V/2A DC jack 5.5mm x 2.5mm (center positive)
The first mid-range integrated amplifier with tone control function is now available as an FX-AUDIO product!
[Product features]
■Higher sound quality with artwork
Low noise and high separation are achieved through circuit design and artwork based on unique know-how.
■Pre-stage amplification circuit using operational amplifier
Adopts Texas Instruments' audio operational amplifier "NE5532" (DIP socket type).
The sound quality is adjusted before the power amplifier IC, so advanced users can enjoy getting closer to their desired sound quality by replacing the operational amplifier!
■FX-AUDIO - First mid-range product equipped with tone control circuit
Equipped with a tone control circuit (negative feedback type), which was often requested by mid-range models, it achieves both convenience and sound quality.
Like the front-stage amplifier, it uses the Texas Instruments audio operational amplifier "NE5532" (DIP socket type), so it is possible to adjust the sound quality by replacing the operational amplifier with this circuit.
■Equipped with an active filter in the operational amplifier IC power supply
An active filter is configured in the power supply circuit to the operational amplifier, and high quality sound is achieved by supplying clean power.
■Higher sound quality due to efficient bulk capacitor placement
The power supply smoothing capacitor uses Nippon Chemi-Con's W series large capacity 8100μF. Coupled with ELNA RE3 (85℃ product) 330μF placed right next to the digital amplifier IC "TDA7498", it achieves a smooth sound quality without sound loss even at high volumes.
■Special parts selection
An audio grade 85 degree capacitor manufactured by ELNA is used as the input coupling capacitor to the front stage operational amplifier, and a film capacitor manufactured by TDK EPCOS is used as the digital amplifier IC input coupling capacitor.
On the output side, the inductor is a TDK power inductor, which is standard for digital amplifiers, and the output filter is a well-regarded TDK EPCOS film capacitor, Arcotronics/AV R82 63V/0.22μF (Made in Italy) metallized film capacitor, etc.
From input to output, parts with a reputation for sound quality and stability are used to create uncompromising sound.
[Notes]
-The power supply for this product is sold separately. A separate AC adapter is required for use.
*The DC plug shape of this product is compatible with outer diameter 5.5mm and inner diameter 2.5mm types.
If you are using an AC adapter with a 2.1mm inner diameter DC plug, you will need the following plug conversion cable and plug conversion adapter.
