FX-AUDIO-brand standard digital stereo power amplifier (50W mid-range output class) model
Equipped with the ST Microelectronics "TDA7492PE" digital amplifier IC, this amplifier delivers up to 48W x 2-channel stereo output. Designed for use as a simple power amplifier, this affordable model offers exceptional sound quality.
Based on a reference circuit, it efficiently arranges circuits that improve sound quality at low cost, without omitting any circuits that affect sound quality.
Furthermore, by using high-quality components, including custom-made audio components, in key areas that improve sound quality, it achieves high resolution and flat sound quality.
Product Features
◆Equipped with the Swiss ST Microelectronics TDA7492PE Dual-BTL Class-D digital amplifier IC
Maximum output: 48W + 48W @ 24V
This digital amplifier IC delivers high output with high efficiency and low power consumption, with a conversion efficiency of over 80%.
The TDA7492PE delivers clear, high-resolution sound while maintaining an analog-like listening experience.
Despite its compact size, it delivers astonishingly high output power, capable of driving even large speakers.
◆Custom-made capacitors renowned for their excellent sound quality are used in the input coupling section.
The input coupling capacitor, which determines sound quality, is an audio-grade polyester film capacitor custom-made exclusively for FX-AUDIO limited-edition models.
This custom-made capacitor was first used in limited-edition models such as the TUBE-00J LIMITED, and its overwhelming popularity led to its inclusion in the mass-produced TUBE-00J UNLIMITED.
◆High-current compatible magnetically shielded (closed magnetic circuit) SMD inductor.
The inductor's low line impedance and high-current compatibility reduce impedance-related sound distortion.
Furthermore, the magnetically shielded inductor eliminates magnetic field binding, ensuring the original filter performance and stable frequency response as designed.
◆The output stage filter capacitors use ITW (PAKTRON) RA series capacitors (MIL-spec).
To meet MIL-spec standards, special manufacturing processes, including manufacturing in a reduced-pressure chamber, are used to prevent moisture and air contamination, contributing to high-resolution, clear sound quality with excellent characteristics.
These proven capacitors have been actively used in sound-conscious models and have been highly praised for their high-resolution, clear sound. Their excellent compatibility with the input coupling capacitors further enhances sound quality by adding high-resolution, clear sound.
◆The power supply smoothing capacitors are made in Japan with high-capacity, low-impedance grade capacitors.
Delivers a clean, stable power supply, contributing to overall sound quality improvement.
◆Equipped with a DIP switch for selecting bass gain settings.
Four bass gain settings (20.8dB, 26.8dB, 30dB, and 32.8dB) can be easily selected using the DIP switch on the back of the unit.
You can adjust and combine settings to suit the type, capabilities, and gain of your preamplifier.
*Default setting (ALL OFF) 20.8dB
*Turn the gain setting switch with the power off.
-Backlighting on the back of the volume knob
-Gold-plated RCA input connectors, gold-plated speaker output connectors, compatible with both straight and banana plugs
-The aluminum alloy housing is lightweight and highly rigid, with a hairline finish for a premium feel
-The body is further anodized for scratch resistance
-The front panel control holes are CNC-machined and tapered for a beautiful design
[Notes]
-The product warranty period is 6 months from the date of purchase.
-Always turn the unit off when adjusting the gain.
-The power supply is sold separately. Please purchase an AC adapter separately.
