Its voice tends to be colder and harder. requires attention.
 
Supply voltage + -55V or less.
 
 
Parameters:
 
Power = 120W /8R + -50V voltage
 
           200W 4R + -50V voltage
 
THD<0.0005% 1K HZ 10W
 
SR = 35V/US
 
Damping factor >200, 8 ohm load
 
Input Sensitivity = 1.6V Output 120W 8R
 
Frequency Response Range = 15HZ-50K HZ (-3DB)
 
20HZ* 20K HZ =-0.02 DB
 
Static current = 80MA
 
Voltage Range = DC Positive + Negative Voltage + -12V to + -55V
 
Voltage magnification = 31 times
 
L12-2 has exceeded thousands of users since 2006, and it all reflects very good. It is a classic model of the L series.

Test chart:
 
Input signal -THD+N test
 
When the input voltage is 700MV, the output voltage is approximately 8V ohms at 23VPP.
 
Test the following picture: Use an 8-Ohm 1000W power resistor.
