【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-brand digital stereo power amplifier (50W intermediate output class) standard model
Equipped with the ST Microelectronics "TDA7492PE" digital amplifier IC, it is capable of maximum 48W x 2ch stereo output, and is an affordable model designed to be used as a simple power amplifier, with a focus on sound quality.
Based on the reference circuit, we have efficiently arranged circuits that can be expected to improve sound quality at low cost without omitting any circuits that affect sound quality.
Furthermore, by using high-quality parts such as custom-made audio parts in key areas where sound quality can be improved, we have achieved high resolution and flat sound quality.
[Product features]
◆ Equipped with Swiss ST Microelectronics TDA7492PE Dual-BTL Class-D digital amplifier IC
Maximum output 48W+48W @24V
This is a digital amplifier IC that can demonstrate high output with high efficiency and low power consumption with a conversion efficiency of over 80%.
The TDA7492PE is characterized by high-resolution sound with less cloudiness while retaining the analog-like listening experience.
Despite its small size, it produces surprisingly high output power and can drive large speakers.
◆Uses a custom-made capacitor with a reputation for sound quality in the input coupling section
For the input coupling capacitor that affects sound quality, we have adopted an audio polyester film capacitor that was custom-made exclusively for FX-AUDIO-limited production products.
This custom-made capacitor was used in limited edition models such as the TUBE-00J LIMITED, and received a great response and led to the mass production model of the TUBE-00J UNLIMITED.
◆Uses large current compatible magnetically shielded (closed magnetic path) type SMD inductor
By suppressing the line impedance of the inductor and supporting large currents, sound distortion due to impedance is reduced.
Furthermore, since it is a magnetically shielded inductor, there is no magnetic field binding, ensuring the original filter performance and stabilizing the frequency characteristics as designed.
◆ITW (PAKTRON) RA series capacitor (MIL standard product) is used as the output stage filter capacitor.
In order to comply with MIL standards, special manufacturing methods are used, such as manufacturing in a depressurized space, and there is no contamination of moisture or air, contributing to excellent characteristics and high resolution and clear sound quality.
This is a proven capacitor that has been actively adopted in models that emphasize sound quality, and has been well received for its high resolution and clear sound quality.It is also compatible with input coupling capacitors, and we have added the trend of high resolution and clear sound quality to further improve sound quality.
◆The power supply smoothing capacitor is equipped with a high ripple compatible, low impedance grade large capacity capacitor made in Japan.
It provides a clean and stable power supply, contributing to overall improvement in sound quality.
◆Equipped with base gain setting changeover DIP switch
The DIP switch located on the back of the main unit allows you to easily switch between 4 patterns of base gain: 20.8dB/26.8dB/30db/32.8dB.
Adjustments and combinations can be made according to the type, ability, and gain of the preamp.
*Default state (ALLOFF)20.8dB
*Be sure to turn off the power when changing the gain setting switch.
・Backlight effect on the back of the volume knob
・RCA input connection terminal gold-plated, speaker output terminal gold-plated, compatible with both straight and banana plugs
・The aluminum alloy casing is lightweight and highly rigid, and the hairline surface treatment creates a high-quality feel.
・The body is also hardened with alumite to make it more scratch resistant.
・The control hole on the front panel is CNC machined and tapered to create a beautiful design.
[Notes]
・The product warranty period is 6 months from the date of purchase.
・Be sure to set the gain with the power of the main unit turned OFF.
-The power supply for this product is sold separately. Please purchase an AC adapter separately.
