The Singxer SA-90 class A/B mono power amplifier delivers ultra-low-noise, ultra-low-distortion performance while offering no less than 200W output power at 4 ohms. Like most power amplifiers on the market, it adopts a monoblock design with a simple, minimalist look.
On the interface side, there's a balanced input on an XLR connector, as well as an RCA input with a GND terminal and, of course, a speaker terminal for the output. This amplifier also features audiophile components such as a toroidal transformer rated at 300W, 20,000uF electrolytic capacitors and no less than 4 low-noise discrete power supplies, as well as full speaker protection functions: power on/off, overtemperature, short circuit, overload and much more. A further feature is the ability to adjust its gain to two levels, 16dB or 23dB, enabling it to adapt to different input signals if required.
