IP network multi-function all-in-one machine(with 6OW/120W/240W/350W integrated constant voltage power amplifier) ? ? PURPOSE: ? Suitable for WAN distributed use. Supports both connected to the Internet management, it also can as a small independent system. ? FEATURES: ? 1. Using 4.3 inch TFT true color LCD screen, control knob, support infrared remote control ? 2. Network constant voltage amplifier (100V constant voltage output or constant resistance output), with a 4 zones control function; ? 3. With pre-function (1 local moving coil mic input, 2 local line mic input, 2 auxiliary line input, 1 network audio), each audio channels with independent volume control; ? 4. Support local SD card timing automatic playback (built-in clock chip) and manual play, remote update SD card content; ? 5. Support the intercom function, built-in intercom microphones and speakers; ? 6. 3 short circuit input and 2 short circuit output is used for linkage; ? 7. Provide audio line output, expanding external power amplifier; Standby power is low, free shuts down some amplifier electricity; ? 8. Works everywhere as long as Ethernet available,being span net segment and routing; ? ? SPECIFICATIONS ?
