Product Details:
Based on the class FM801 amplifier circuit.
The left and right channels are completely independent without any electrical connection.
Excellent layout, amplifier super stable, without any noise.
This machine has a single ended, balanced 2-way input, can connect 2 preamplifiers, and uses relay switching.
Use 28pcs precision paired ON high-power transistor MJL4281. (Pairing accuracy<1%)
Use 16pcs of brand new precision testing paired with metal packaged transistors 2N3440/5416. (Pairing accuracy<1%)
Each large transistor has decoupling capacitors and decoupling electrolytic capacitors.
Use 1200W high-quality Nippon Steel core transformer. (Independent winding of left and right channels)
Use 80000uF ELNA FOR AUDIO high-quality capacitors.
Use original Swiss Schuster power sockets and 5pcs Schuster gold-plated fuses.
Use Single crystal copper signal wire and American ALPHA solder wire for welding.
Power on soft start and Perfect horn protection circuit.
Use CNC precision machining for all aluminum chassis.

To ensure quality, each finished machine needs to undergo comprehensive AP testing to ensure it meets the design specifications.
The tests include: bandwidth, noise (signal-to-noise ratio), dynamic range, distortion, intermodulation distortion, channel separation, amplification factor, etc.
AP Test Parameters:
↓↓↓ Test data with 8 Ω/700W load ↓↓↓
↓↓↓ Distortion and waveform at full power ↓↓↓
