SIP Rack Mount network playback terminal 731V

SINREY SIP731V is a rack-mount playback terminal equipped with a 10/100M Ethernet interface. On the rear panel, it features a set of AUX audio input, a set of AXU audio output, and a 220V AC relay output directly connectable to a pure post-amplifier. This configuration enables the post-amplifier to play both network and local audio. Additionally, the terminal includes a 6.35mm interface for microphone input, three volume adjustment knobs, and a level indicator. These features cater to local amplification and volume adjustment needs.

SINREY SIP731V is a SIP network broadcast decoding pre-device specifically designed for network decoding functionality. It receives audio data from the network and delivers audio output. Collaborating with SIP servers and SIP network microphone hosts, the SIP731V is utilized in the main control room to facilitate functions such as timed ringing, real-time voice broadcast, and emergency broadcast.

Installation & Configuration

The SIP731V is indoor rack mountable with RJ45 network interface and AC power interface. Upon power-up, the SIP731V will automatically obtain an IP address (BootP or DHCP) or find its IP address using Manager software. The unit can also be easily configured and controlled via a standard web browser.

Application Development & Integration

SIP731V supports various control and communication modes, and we provide development documentation and programming examples for playback as well as SIP intercom (off SIP server). Serial port control commands and network control commands are also available. Software developers can write their own audio applications with custom features.
