Power Amplifier
QC Series
AT A GLANCE
1: High-efficiency radiator, stepless variable speed cooling fan, to ensure that the power amplifier works at a lower temperature.
2: Large toroidal transformer to ensure sufficient power supply.
3: Exquisite shape, standard mounting holes.
4: Complete protection, including limiter, on/off shock prevention, DC protection, output short-circuit protection, and overheating protection.
5: Built-in limiter, it is a very effective protection appliance to prevent damage to the speaker.
6: Excellent audio performance, it has excellent signal conversion characteristics, it has very small harmonic distortion (THD) intermodulation distortion (SMPTE-IM), instant intermodulation distortion, pure and natural sound quality interpretation.
7: Stereo (STERER), bridge (BRIDGE), and (PARALLEL) working mode.
8: Each channel has its own Signal and Clip indicator.
9: When the protection circuit works, the Fault indicator lights up and the sound output stops automatically.
10: Front panel level gain control.
11: The new SMD component technology, the product is stable and reliable.
12: The transistor is in direct contact with the radiator and quickly dissipates heat.
13: Optimized heat dissipation system makes the whole machine work stably, with automatic variable speed fan.
14: Unique short-circuit lock and automatic judgment reset function, so that customers' intuitive performance is more reliable
