Product Description
Use the balance XLR input socket, the professional output connector SPEAKON, convenient for using.
The perfect circuit protection have guaranteed the stability of the unit:
1. Temperature Protection: To avoid the defective because of overheat, when the inside temperature arrives to 95¡ æ , the power amplifier will cut the connection with the speaker automatically, when the temperature goes back to 70¡ æ , the power amplifier returns to work fine automatically.
2. Short Circuit Protection: To guarantee the unit and the connected speaker working safety even it was some mistake operating. Built-in clip limiting circuit have decreased the distortion(central and surround without the clip circuit), full protect the loudspeaker and makes it working more stability.
3. Cooling System: Use the big whole aluminum radiator to increase the cooling ability, it connects with two speeding fans which makes the unit cooling down highly effective. Each of the optimized design can guarantee this power amplifier will not be overheat when it keep working very long time, it will not be protected only itself when overheat which likes the other normal power amplifiers.
4. Output delays when just turn it on, mutes when just turn it off, it protects the loudspeaker not getting destroyed by the strong noise of the current surge, specially for the high frequency. The good audio performance has the high quality signal transformation characteristic, it performs the pure natural sound with very less THD, intermodulation distortion (SMPTE-IM) and transient intermodulation distortion.

Viewing through China PA history, with the recession of home audio and the emersion of professional audio business opportunities, there rise a large number of manufacturers, within which, some are well qualified ones. But unfortunately, as always existing at the primary stage of every industry, there are quite a few of badly-equipped small factories looking after quick money.
DEMA products are mostly exported to European markets, some are well accepted in many Asian countries, and quickly gain the market favor from some American, Australian, African countries. High end acoustic system of DEMA, the sound reversion can reach even surpass some well-known European or American brands.
