HIKVISION DS-QAE0A240G1-VB6 240W 6-Zone Analog Amplifier EMC/MIC/AUX/Bluetooth/USB/SD Card Audio Input

DS-QAE0A240G1-VB6240W 6-Zone Analog AmplifierThe device has 2 auxiliary (AUX) line inputs, 1 emergency (EMC) input, and 2 microphone inputs; 1 auxiliary output, capable of cascading to the next power amplifier. Microphone 1/2, emergency line input, and line 1/2 can be independently adjusted, and it also has total volume control. Built in Bluetooth/MP3 function module for content playback on the phone. Equipped with six independent volume adjustment output functions. Mic 1 and emergency line EMC inputs have the highest priority level, while Mic 1 and EMC have mixed outputs that can strongly cut other audio input signals. Mic 2, Line 1, Line 2, and MP3 (Bluetooth/SD/USB) have mixed output. Equipped with high and low frequency adjustment function. Equipped with advanced short-circuit, overheating, and overload protection functions. The circuit is equipped with amplitude limiting function to prevent excessive output of the amplifier and protect the speaker. Supports multiple indicator light displays (power, signal). By adopting a forced cooling structure with a fan, the machine can operate for a long time.
