SINGXER SA-90 MONO POWER AMPLIFIERS
It is a unique 2-channel amp that can be bridged for 1 or 2-channel operation using simple switches on the rear panel. Power your audiophile 2-channel music system or bridge 2 channels and use 2x AMP-F2 for high power requirements . Flexibility, substantial power and great value: EverSolo AMP-F2.
The all-new SAPS switch-mode power supply provides the audio circuit with a clean electrical signal, ensuring very low noise and distortion levels. Bridgeable, the AMP-F2 is a versatile model that can be used in stereo or mono.
Features
Power supply capacity of heavy material design: each channel is powered by a shielded toroidal transformer with a capacity of 300 watts of high power (maximum short-term power can reach 500 watts); 20000uF Dalian Wave Current imported ruby electrolytic capacitors; 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;
High and low gain adjustment 16/23db; Support high and low gain adjustment Single-End balanced switching, double input switching, no mutual interference
Advanced speaker protection function: overheating switch, overload, DC protection
Optional 12V Trigger Input
Exclusive Magna Hifi Upgrade: 12V Trigger Input for Singxer SA-90 Mono Power Amplifiers
This modification is done securely and safely — with full respect for the original design — and without voiding your warranty.
When you order a stereo pair, a short split cable is included to make setup easy.
You can choose an optional 2 meter or 5 meter trigger cable at no extra charge. Custom lengths are available on request.
See our SA-90 trigger input blog for more information on the 12 Trigger input

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)
