Product Description
Name: Class H desigh professionsl power amplifier /audio amplifier(QS7112)
Product Feature:
Class H output stage circuit design, high stability, low heat, high efficiency, more stable, more reliable quality.
High-power design, output powerful, deep bass, clear hierarchy, with the bold outline shape echoes the machine, thus more able to meet customer demand.
Using SMT technology, more stable performance; Power tube using ON Semiconductor's power management, better tone; Double bass more powerful transformer.
Built-in temperature compensation technology, working conditions remained stable at high temperatures; Three intelligent protection mode, DC protection, Short circuit protection, thermal protection, intuitive power indicator and protection instructions, to improve the reliability of the product provides a strong guarantee.
BRIDGED, STERO, PARALLEL three output modes arbitrary choice for a variety of occasions; Automatic intelligent fan speed function, the fan speed is accelerated with Increasing temperature; 30 Hz high-pass filter, bass neat.
The machine also has the power limiter design features two outputs can be connected 4Ω , 8Ω , 16Ω Speaker, line array sound for a variety of combinations.

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.
