Singxer - SA-90 klasse AB mono-eindversterkers
Deze high-performance mono modulaire Hi-Fi versterker is een state-of-the-art Class AB versterker ontwikkeld door Singxer na vele jaren van onderzoek. Het beschikt over een ultra-hoge bandbreedte, ultra-lage ruis en ultra-lage vervorming. De prestaties hebben een wereldleidend niveau bereikt, met volledig gescheiden en onafhankelijke linker- en rechterkanalen voor optimale kanaalscheiding. De schakelingen van de versterker, in eigen huis ontworpen, maken gebruik van een high-performance, high-speed ontwerp dat zorgt voor lage ruis, lage vervorming en uitzonderlijke geluidskwaliteit.

SINGXER SA-90 MONO POWER AMPLIFIERS
This is a high-performance monaural split HIFI class AB amplifier. It adopts a design with ultra-high bandwidth, ultra-low noise, and ultra-low distortion, and its performance indicators have reached the world's leading level. The left and right channels are completely separated and independent, achieving the ultimate level of channel separation. The power amplifier circuit adopts self-developed high-performance differential amplification high-speed circuit, which has the characteristics of low noise, low distortion, and high sound quality.
Features
- High and low gain adjustment 16/23db; Support high and low gain adjustment Single-End balanced switching, double input switching, no mutual interference
- Power supply capability for rich material design: each channel is powered by a shielded ring transformer with a rated power of 300 watts (maximum short-term power can reach 500 watts); 20000uF large continuous wave current for Rubycon electrolytic capacitor; designed 4 separate ultra-low noise power supplies for the small signal section of the circuit.
- Handcrafted precision matching of differential grades, paired with high-quality components such as precision resistors and imported thin film capacitors; The circuit adopts a simple design, but transistors with excellent linearity are used wherever the audio signal passes through.
- Under the same level of performance, we adopted a low open-loop gain design, achieving low transient intermodulation distortion and excellent listening experience.
- Supports switching between two types of inputs with single ended balance, without interfering with each other.
- Advanced speaker protection function: overheating switch, overload, DC protection
- 4 discrete ultra-low noise power supplies are designed for the small signal part of the circuitManually fine-tuned differential stages, combined with high-quality components such as precision resistors and imported film capacitors; the circuit is simple in design, but transistors with particularly excellent linearity are used where the audio signal passes.
- With the same level of performance, we use a low open-loop gain design to achieve low transient intermodulation distortion and obtain low transient intermodulation distortion; excellent listening experience;

Below extreme test, with 2 ohm load, the output can also be stable. (2 ohm load is not our recommended load, so this test only shows that it can work stable under 2 ohm load)
