Adhering to the Danish descent,Danish AVANCE carefully created professional high-end two-channel A-series amplifiers in 2014. A series power amplifier circuit is mature and stable in performance. Its design uses a large heat dissipation system with a spec


1. The soft start system is turned on to protect the power amplifier and power supply system from current impact

2. Balanced two-channel standard structure

3. The output circuit with limiter, when the input voltage amplitude is too large, it will automatically compress the amplitude of the input voltage to avoid wave cancellation output and protect the speaker system from being burned due to overload

4. Perfect protection circuit: including DC output protection, overload protection, short circuit protection, and a fuse protector on the power amplifier backplane

5. High-rigidity thick panel with steel high-strength chassis, durable, good seismic performance and easy maintenance

6. Canon, balanced input sockets, professional terminal output terminals, to meet the requirements of fast and convenient system connection during engineering and mobile performances

7. Two working modes: dual channel and bridge
