VoIP Amplifier JWDTE02
JWDTE02 pre-amplifier, also known as an IP power amplifier, is primarily suitable for various audio system applications. Its key feature is its support for multiple signal inputs, including three line inputs, two MIC inputs, and one MP3 input, to meet diverse audio source requirements. Its wide operating range, from -20°C to 60°C and humidity ≤ 90%, ensures stable operation in all environments. It also features a waterproof design, achieving IPX6 protection. Built-in overheating protection ensures safety. Furthermore, its strong frequency response and excellent distortion protection ensure high-quality sound. With selectable communication protocols and high cost-effectiveness have earned it widespread acclaim in applications such as campuses, scenic spots and airports.
