Features:
Using a 4.3-inch touch TFT display, all operations are adjusted through the touch screen. The 8-channel channel number, frequency, power, volume, and audio level are clear at a glance.
Built-in howling suppression, which can be turned on or off as needed
Built-in 4 EQ modes, the user mode can freely and flexibly adjust the 11-band EQ gain, adapting to more occasions.
Using antenna diversity reception technology, the CPU automatically selects the optimal antenna to ensure stable signal reception and prevent frequency interruption.
Preset multiple sets of frequencies to avoid interference, effectively improving the installation efficiency on site.
It has the function of one-key mute, which can mute 8 channels at the same time.
The display operation has a locking function. After locking, functions such as channel adjustment and volume adjustment cannot be used to avoid unnecessary trouble caused by misoperation by non-staff members.
