To avoid this, if “PRI” and “PRD” protection function has been ac- tivated 3 times continuously, the power will not turn on even when the “STANDBY/

43、ON key is pressed. In order to turn on the power again, dis- connect the power cable of the main unit from the AC outlet once and then reconnect it again. The output transistors in each amplifier channel should be checked for damage before applying power of the main unit. Amplifier current should be

44、 monitored by measur- ing across the emitter resistors for each channel.
