800 Watts 4 Channels High Power Amplifier
Features&Benefits:
The all-new Class-TD type 4-channel professional amplifier features high efficiency, pure sound quality, and low heat generation;
Adopting a ring transformer for power supply, with stronger low-frequency and better force;
Efficient heat dissipation system, extremely low temperature inside and on the surface of the chassis;
SMT patch technology for more stable performance;
Ultra protection system, high-frequency protection, overload/overcurrent protection, over temperature protection, output short circuit protection, DC protection, distortion limiting protection, etc;
The unique function of increasing the startup volume can protect you from accidental operation and damage to the speaker;
The smaller and lighter chassis contains greater power and is extremely convenient for touring applications;
Professional grade fever capacitor, more powerful at low frequencies, clean and clear at high frequencies.
