Name: QSN British Brand 800w power amplifier(QM4108)
Switch AC soft start: Inhibition of starting current, does not affect other equipment, protection of internal line from impact.
Boot delay protection PICK: Speaker from impact, silent boot. DC output load break protection: The midpoint drift or DC output, automatic cutting load, prevent speaker by impact damage.
Output current limiting soft protection: When the input signal is too large power peak clipping, protection system for the automatic detection and signal compression, protect the speaker.
Load short circuit protection: When the output short circuit protection, automatic cut off the output, power amplifier power amplifier; When the resumption of work after the termination of the automatic short circuit.
Overheating protection: When the temperature is too high overheat protection system automatically cut off the load; Automatically return to work after temperature reducing system.
Shutdown protection: Shutdown system to cut off the load, the silent speaker shutdown, protection from impact.

Guangzhou YunQiang Electronics Co., Ltd. is a professional audio manufacturer which has R& D, Production department, Marketing Dept., and Technical and service Dept.,
The main products include: Power Amplifier, Karaoke amplifier, Professional Speaker, Karaoke speaker, Sound Mixer, Audio processor and Conferencing systems.
Nowadays, in professional sound industry, more and more people are seeking for amplifiers with light weight, high power output, high sound quality and high stability.
To get good sound quality, we should have high quality components. And to ensure the stability, we must solve the problem of heat dissipation. Now, we have this amplifier FP14000, FP10000Q, FP-8000Q. Our FP14000, FP10000Q, FP-8000Q is Class TD switching amplifier fixed with NOVER (from UK) power capacitors, ON-Semi power transistors other high quality electronic spare parts. Professional circuit design and actual copper heat sink with better structure make fast heat dissipation possible. And fast heat dissipation contributes to high stability of the amplifier. Once you have our amplifiers at your hands, open the chassis, you will find artwork and detail difference. The swich power amplifier can be used to drive line array loudspeaker systems in touring, living show and other applications with high requirement on sound quality and stability.
Since the foundation of our enterprises, we have been concentrating on designing new products, doing research on new sound technology, training our staff, as well as improving our quality to products and management system. And now we have had a unique management experience, advanced production equipment, abundant design capability, and the large marketing network and after-sales service system.
Now we have passed newest CE, FCC, RoHS, SGS, CCC, ISO9001 on March, 2015.
