The DA system amplifier is a high-performance amplifier designed with most advanced and efficient power switching (SMPS) and TD power amplifier circuit (CLASS TD).

It uses a highly efficient amplifier circuit to provide very high output within a limited 1U space. The TD amplifier operates at close to the efficiency of CLASS D power amplifiers and represents the industry's best combination of performance and sound quality. DA uses high-quality porous heat sinks with a patented design to ensure fast heat radiating. The DA switching power supply uses intelligent adjustable control technology (R SMPS) with stable and efficient performance to ensure stable output under a variety of AC voltage fluctuations (190V-250V). The switching power supply transformers use imported Teflon coated high temperature wires to ensure inside components can work efficiently under all conditions. DA has eight optional sensitivity and compression modes. TD features light weight, small size, and outstanding sound quality ensuring that it will be a favorite in a variety of night fixed installation and live sound situations. The sound quality of the TD amps is similar to warm Class AB amplifiers used in professional HIFI and they represent the perfect combination of tone and power.

Features

• Full range of protection: short circuit, overheat, overload, over-current, output DC, soft start, current fuse protection and transformer overheat protection
• When the load connected to the amplifier is less than rated, the output power will be automatically controlled; the power will be kept constant within a safety range, greatly improving the stability of the amplifier.
• Especially design for professional high-end amplifiers, also known as the zero crossing turn-on/turn-off technology, minimizes start-up current draw.
• A unique smart thermal regulation circuit, coupled with an aviation industry high-density aluminum radiator helps regulate the unit’s operating temperature and ensure high stability.
• Amplifier modules use tunnel architecture, greatly improving cooling efficiency and stability.
• The use of a large power bridge rectifier, together with a high-density aluminum grid radiator, ensures optimal performance under large dynamic range and large SPL demands and improves the load capacity and stability of the amps. The amplifier circuit is optimized and improved from a traditional HIFI-class TD circuit. The sound quality is natural, transparent, smooth with excellent extension in the mid/high frequency range. Precision, low noise resistors and capacitors ensure high performance and zero drift of the circuit.
