Singxer SA-90 HiFi Class AB Ultra-low Distortion Mono Power Amplifier 200W High Power Audio Amplifier 90W/8ohm, 180 W/4ohm

Description:
- 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:
- 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.

Specification:
- Rated power: 90W/8ohms; 180W/4ohms
- Maximum power: 122W/8ohms; 202W/4ohms at 1% THD+N
- Ultra-low bottom noise level: <2.3uV (A-weighted), <3uV (not weighted) at single ended input low gain
- SNR: >140dB (A-weighted) at single-ended input low gain
- THD+N: -110dB (A-weighted), 8ohms 20W
- Damping coefficient: 800 at 8ohms
- Support high and low gain adjustment: 16/23dB
- Protection: power on/off protection, overheating protection, short circuit protection, overload protection, DC protection, etc.
- Single machine size: 21.6 x 32 x 8cm
- Support 115/230V AC power supply switch
- Single machine net weight: 7.5kgDescription:
