The Fosi Audio BT20A Pro is an innovative Hi-Fi Stereo preamplifier that combines high sound quality with modern connectivity features. With the ability to play in two channels, it offers rich and clear sound for every type of music.
More specifically, the preamplifier features:
Preamplifier compatible with analog audio sources.
Bluetooth support, allowing connection with wireless speakers or other devices.
It is ideal for those who want to upgrade their audio experience without compromising on sound quality. With the Fosi Audio BT20A Pro, you enjoy your favorite music with a new dimension.
Unmatched Power with the TI TPA3255 Chip
The heart of the BT20A Pro beats with the top-tier Texas Instruments TPA3255 chip, which delivers an impressive power of 300 Watts x2 at 4Ω. The advanced feedback design and exclusive high-speed gate driver error correction ensure that the sound remains true to its source. Despite its enormous power, the amplifier achieves exceptionally high energy efficiency, keeping standby losses below 2.5W, combining performance with economy.
Hi-Fi Quality and Interchangeable Op-Amps
The BT20A Pro is a significant upgrade aimed at demanding audio enthusiasts. It features two plug-in NE5532 Op-Amps, which can be easily replaced with models such as the SS3602, MUSES02, or OPA2134PA, allowing you to "tune" the sound quality to your own preferences. With a signal-to-noise ratio of SNR ≥108dB and ultra-low harmonic distortion THD ≤0.005%, the sound clarity remains unsurpassed across the entire frequency range.
Upgraded Bluetooth 5.0 Connectivity
The wireless experience reaches new heights with Bluetooth 5.0, offering a stable connection and long range. The amplifier features an intelligent Bluetooth memory function for automatic pairing, while also providing the option to instantly clear connected devices by holding down the volume knob for five seconds. The external antenna included in the package ensures that the signal remains strong, allowing you to enjoy your music without interruptions from any device.
Ultimate Sound Control (Tone Control)
The unique design of the BT20A Pro gives you complete control over your acoustic experience. It features independent controls for bass and treble, allowing you to boost or attenuate frequencies depending on your space or music genre. For those who love an absolutely natural sound, there is the option to set the effects to the middle point, so you can listen to the original source without any processing, preserving the authenticity of the recording.
Flexible Inputs and Pre-out Output
The amplifier offers multiple connectivity options for any modern setup. In addition to wireless connection, it features an analog RCA input for connecting CD players, turntables (with preamplification), or a DAC. On the output side, apart from the terminals for passive speakers, you will find a Pre-out port, which allows you to connect an active subwoofer or an additional amplifier, turning your system into a complete audiovisual center.
Complete Package and Reliability
With the purchase of the BT20A Pro, you receive a complete ready-to-use package, which includes the 32V/5A power supply, the Bluetooth antenna, and the user manual. Fosi Audio guarantees build quality by offering a 24-month warranty, ensuring the trouble-free operation of your system. Its compact aluminum design not only provides an elegant appearance but also acts as an effective heat sink, ensuring the longevity of the electronic components.

This is a wonderful little amplifier that I have connected to my old speakers without a built-in amplifier. I use it with my laptop, tablet, or mobile phone, and the Bluetooth connection works flawlessly.
I am very satisfied with this product and would recommend it.
Πρόκειται για έναν υπέροχο μικρό ενισχυτή που έχω συνδέσει στα παλιά μου ηχεία χωρίς ενσωματωμένο ενισχυτή. Τον χρησιμοποιώ με τον laptop, το tablet ή το κινητό μου τηλέφωνο, και η σύνδεση Bluetooth λειτουργεί άψογα.
Είμαι πολύ ικανοποιημένος με αυτό το προϊόν και θα το συνιστούσα.
For the money and the purpose I bought it for, I give it 4 stars.
105 euros, with a 48V power supply included in the price.
In a utility room, gym-garage 70 sq m, it fit perfectly. I did not expect such power from such a tiny amplifier.
Mostly Spotify from a phone.
With Bluetooth, the sound quality drops a little; it does not have modern Bluetooth codecs, which is the only bad thing about it. It does not support LDAC or any APTX, but wired, with RCA from a phone and a DAC or sound card for phones in between, the sound is very good.
Connected to a pair of Fenton SHF700B floorstanding speakers.
Anyone who hears the sound from the speakers and sees this amplifier is amazed.
I am very satisfied, although the latest version, the BT20A MAX, is the best there is, with Bluetooth sound quality equal to CD, without losses.
Για τα χρηματα του κ το σκοπο που τον πηρα βαζω 4 αστερακια.
105 ευρω, μαζι με 48v τροφοδοτικο, μεσα στην τιμη.
Σε βοηθητικο χωρο, γυμναστηριο-γκαραζ 70τμ, ταιριαξε κουτι. Δεν περιμενα τετοια δυναμη απο εναν τοσο δα μικρο ενισχυτη.
spotify κυριως απο κινητο.
Με μπλε δοντι, πεφτει λιγο η ποιοτητα του ηχου δεν εχει συγχρονους αποκωδικοποιητες bluetooth, το μονο κακο που εχει. δεν υποστηριζει δλδ LDAC κ κανενα APTX, ενσυρματα ομως, rca με κινητο, κ ενα dac η' καρτα ηχου για κινητα ενδιαμεσα, ο ηχος ειναι πολυ καλος.
Συνδεδεμένο με ενα ζευγαρι Fenton SHF700B δαπεδου.
Οσοι ακουν τον ηχο απ τα ηχεια κ βλεπουν τον ενισχυτη αυτον, παθαινουν πλακα.
Ειμαι πολυ ευχαριστημενος, αν κ η τελευταια εκδοση του, ΒΤ20Α ΜΑΧ, ειναι οτι πιο καλο υπαρχει, ποιοτητα ηχου απο bluetooth ισαξια με cd, χωρις απωλειες.
