L25 combined amplifier parameters:
The output power is 250W 8R, 500W 4R+- 70V
200W 8R, 400W 4R+- 63V power supply
125W 8R, 250W 4R+- 50V power supply
250W 4R, 500W 2R+- 50V power supply
Maximum output current 20A, maximum output voltage sine wave+- 67V (under+- 70V power supply)
Static current 20MA per channel
Static power consumption=power supply voltage * 0.02 (2W+- 50V)
Power Supply Voltage:+- 24V to+- 70V
Recommended power supply voltage and radiator standard:
+- 35 to+- 50V, radiator 0.5KG per channel
+- 40 to+- 60V, radiator 1KG per channel
+- 60V to+- 70V, radiator 2KG per channel
If the voltage above+- 60V is used, it is recommended to apply silicone grease on the back of the angle aluminum due to the high heating
Good heat conduction with large radiator. Front stage gain 4.7 times. Rear stage gain 25 times. Total gain 117 times.
Frequency response range: 5 HZ-300 K HZ-3DB 20HZ-20K HZ + -0.2DB.
Distortion 100W 1K HZ THD3000, 8 ohm load
Signal-to-noise ratio>97DB
Input sensitivity: 0.6V RMS 250W 8R power
Size: 130mm long Width 95MM including angle aluminum
Test signal diagram:
Square wave test
Input signal and output signal test
When the input signal is 0.7V, the output signal is about 70V. The output power is 250W 8R
Test environment. Large radiator or fan shall be installed for the angle aluminum temperature to make the angle aluminum temperature less than 55C.
