External Equipment Connecting Diagram
When connecting the speaker connector, please confirm the +, - polarity and the left (L) and right (R)
channels, and do not connect the reverse cable. The speaker connector should be careful not to come
off and come into contact with other terminals or the rear panel. In addition, please be careful not to
contact the polarity of the speaker connector or the cable of the channel.
About speaker impedance
If the high-power output for a long time is lower than the speaker (such as 4Ω) of the rated impedance (6Ω, 8Ω),
the built-in protection circuit will automatically start. After the protection circuit is activated, please unplug
the power cord, maintain good ventilation, and reconnect the power after reducing the temperature.
In connecting the signal cable
When connecting the signal cable, after unplugging the power cord of the device, please note that the left
channel (L: white) and rear channel (R: red) of the connection terminal may have some differences with the
equipment. Please refer to the instruction manual of the product before connecting to make sure to connect
correctly. If the left and right signal cables are reversed, the stereo effect will be reduced.
