Single channel class-C power amplifier is used for public address amplifier or commercial power amplifier, 360W/460W/660W/....2000W RMS, support 100V & 4-16 Ohm, 3U height, 19 inch rack mount and 85% efficiency..
Description:
Power amplifier is a device that naturally amplifies audio signals and outputs them to speakers. The input audio signal must be a pre amplified audio signal, which is the most important device in the broadcasting system.
Features:
1. Real time display of device temperature and output volume through LCD.
2. Equipped with RCA and XLR sockets, with a specially added balanced input/output interface.
3. It has constant voltage outputs of 70V and 100V, as well as constant resistance outputs of 4-16 Ω.
4. The output volume adopts a digital adjustment method, with a 32 level digital volume.
5. Friendly indication function: including signal indication, protection indication, distortion indication, power indication, and other functions.
6. Equipped with comprehensive output short circuit protection, overload and overheating multiple protection functions.
7. Configure a high-speed intelligent clipping voltage limiter to provide a larger dynamic range and significantly increase the average output power of the machine.
8. Equipped with a forced start function for the cooling fan, protecting the stable operation of the product.
9. Unique NTC temperature automatic control circuit design ensures lower machine temperature and more stable and reliable operation.
10. Unique power superposition function design: Two DC pure post stage power amplifiers can double the output power through power interconnection, saving user wiring
11. Workload and cost (tailor made features).
12. Equipped with remote on/off, remote total volume adjustment, remote temperature detection, and over temperature alarm display functions.
13. It has a short circuit signal to activate the power on function.
