Technical specifications cover power source, current consumption, audio input/output details, frequency response, distortion, signal - to - noise ratio, separation, audio format, storable audio files, control inputs/outputs, network interfaces, protocols, audio packet transmission, connectors, voice sampling, encoding, packet loss recovery, audio delay, SD section, media, file system, installation, operating temperature and humidity, dimensions, weight, and included/optional accessories.
Using the TOA NX - 300W is easy. First, connect it to your existing LAN or WAN network using the RJ45 connector. Then, you can adjust the audio input channels according to your needs. You can choose between balanced and unbalanced input, and adjust the volume. When it comes to broadcasting audio files, you can set up to 8 different priority levels. For different applications like system intercoms or announcements, use the dual - channel full - duplex capability for two - way communication. Remember, when using the SD card for log storage, make sure it's a compatible SD/SDHC card up to 32GB. Regarding the power source, you can use an external 24V DC power supply or the optional AC adapter AD - 246. During operation, keep the device within the operating temperature range of - 10°C to +50°C (14°F to 122°F), or 0°C to +40°C (32°F to 104°F) when using the AC adapter. Avoid high humidity environments, as the operating humidity should be 90%RH or less with no condensation. For maintenance, regularly check the connections to ensure they are secure. If you need to clean the device, use a soft, dry cloth. Also, keep an eye on the log storage on the SD card and clear it when it reaches the maximum of 10,000 entries to maintain proper functionality.
