● Press the "VOICE PRIORITY" button, Mic1 can be set as the highest priority, which can take precedence over other inputs.

● The line output can provide audio signals for additional amplifiers for cascade expansion.

● The front panel has corresponding led level meter, which can correspondingly indicate the signal level status of each channel.

● It has a variety of protection functions, such as overheating protection, overvoltage protection, overload protection and speaker line short circuit protection, which can prevent it from running under serious misuse.
