JBL SA550 Classic impresses with 90W x2 power, Class G innovation for pure sound. The robust 150W output delivers a rich, detailed audio experience. Bluetooth connectivity and timeless design make it a perfect blend of power and precision.
The JBL SA550 Classic pays homage to the legendary JBL SA600 amplifier of the 1960s, boasting a vintage aesthetic with walnut veneer side panels that perfectly complement JBL Classic and Studio Monitor loudspeakers. However, beneath its retro exterior lies a cutting-edge music system, featuring an advanced amplifier topology that delivers robust power, innovative efficiency, and precise noise control for an immersive musical experience with effortless potency.
Straight out of the box, the SA550 effortlessly connects to your smartphone or tablet through Bluetooth, providing instant access to high-performance music from your preferred services and libraries. With the latest Bluetooth AptX® Adaptive technology, it ensures hi-res audio over Bluetooth with low latency, guaranteeing perfect synchronization of audio and video.
The SA550 Classic introduces an advanced amplifier topology known as Class G, setting it apart by utilizing multiple power supplies compared to traditional amplifiers. The initial power supply delivers 10 Watts per channel in a Class A topology, ensuring minimal noise and delivering pure sound with preserved micro dynamics and details. The incorporation of a substantial heatsink enables stability up to 90 Watts per channel.
Beyond its initial 10 Watts, the SA550 can achieve a sustained output of 150 Watts per channel through a second, higher voltage power supply. To prevent distortion, the SA550 employs high-speed "lifters" that gradually increase power delivery, tracking the music signal and maintaining a 5 Volt headroom. This dynamic approach allows the benefits of Class G amplification to shine while eliminating drawbacks, ensuring seamless power delivery to any speaker system.
The SA550 accommodates three digital and four analog inputs, including a moving magnet phono input for turntables. Digital inputs feature a high-resolution, ultra-high-fidelity DAC with the exceptional ESS DAC chip at its core. While the SA550 exudes the charm of the late 1960s in its exterior design, it seamlessly integrates Hi-res Bluetooth technology, efficient amplification, and exceptional musical performance, establishing itself as a modern classic rooted in today's finest technologies. Elevate your audio experience with the timeless charm and advanced features of the JBL SA550 Classic amplifier.
