SIP Network Constant Voltage Amplifier —SIP735V

—Support SIP protocol— SIP v1 (RFC2543), v2 (RFC3261)
—3 RAC audio interface
—Volume control support
  • SIP735V



SIP735V is acombined fixed-voltage amplifier, supporting standard SIP protocol, with10/100M Ethernet interface, 2 sets of AUX audio input and microphone input with6.35mm connector on the rear panel, which can input local audio source and playaudio from network and local. It is also equipped with 8 volume adjustmentknobs, which are used as playback volume adjustment.

SIP735Vnetwork fixed voltage amplifier has multiple audio inputs and independentvolume adjustment, integrated with network broadcasting and local broadcastingfunctions, power can be selected from 60-650W different versions, whichreceives audio data from the network and provides audio output. SIP735V and SIPserver master control software, microphone host supporting the use of themaster control room to SIP735V terminal for timing ringing, real-time voicebroadcast and emergency broadcast, etc.


— Standard RJ45 network interface, providing online remote upgrade of firmware;

— ARM+DSP—based architecture with high—speed industrial—grade chips, with a start—up time of ≤ 1 second;

— With volume adjustment potentiometer, you can realize the volume hardware adjustment

— With microphone input and line input, you can achieve the local audio source or microphone to achieve local amplification function.

— Support SIP v1 (RFC2543), v2 (RFC3261) and Other network protocols

— Supports wideband G.722, narrowband G.711a/u and MP3 audio decoding protocols

— Support RTP multicast playback protocol, support 10 priority levels, high priority audio can interrupt the low priority

— Support our private broadcast protocol, which can be broadcast shouting, timed ringing and Other operations through our broadcast software

— Provide PC—based IP and Other parameters configuration procedures

— Support firmware remote upgrade
