Designed for music lovers seeking powerful performance in a compact form factor, the BT20A MAX combines high-output Class-D amplification, premium internal components, and next-generation Bluetooth connectivity for versatile home and desktop listening.
At the heart of the BT20A MAX is the Texas Instruments TPA3255 amplifier chip, capable of up to 300W x2 peak power and 180W x2 RMS at 4Ω, paired with PFFB (Post-Filter Feedback) technology to achieve ultra-low distortion, high signal-to-noise ratio, and consistent performance across varying speaker loads. Independent digital and analog power supplies, along with ELNA capacitors, further enhance clarity, dynamics, and tonal accuracy.
Built for modern systems, the BT20A MAX supports 2.1-channel output, featuring dual RCA inputs, passive speaker terminals, and a dedicated subwoofer output for easy integration into compact stereo or desktop setups. A selectable high-pass filter at 80 Hz improves vocal clarity when paired with a subwoofer, while bass and treble controls, along with an EQ bypass mode, allow listeners to fine-tune or preserve the original signal path.
The BT20A MAX is well suited for desktop audiophiles, apartment dwellers, and budget-conscious hifi enthusiasts, says the company. Its compact footprint makes it easy to pair with bookshelf speakers in small listening spaces, while its output power, subwoofer integration, and advanced Bluetooth support allow it to scale effortlessly into more ambitious 2.1 systems.
Wireless performance is supported by a Qualcomm QCC3095 Bluetooth chipset, with support for Bluetooth 6.0 and a wide range of high-resolution codecs, including aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC. This ensures a stable, low-latency, high-resolution streaming experience from smartphones, tablets, and computers.
Additional features include a motorized analog potentiometer for precise volume control via the included remote, 12V trigger support for system automation, and an active cooling design with a newly engineered silent fan and optimized ventilation, improving cooling efficiency by up to 30% during extended listening sessions.
