Speaker Compatibility:
Supports 4 Ω speaker loads for higher output power
Suitable for standard home audio speaker systems
Performance:
Total Harmonic Distortion (THD + N): less than 0.1% at full output (depends on input signal and operating conditions)
Power Supply Section:
Onboard full-wave bridge rectifier
Integrated filter capacitors for DC smoothing
Transformer can be connected directly to the board
