PA announcements from any SIP phone
OPTIMUS expands the SIP compatibility options of its public address systems with the IA-10SIP model, a SIP audio interface to analog audio that allows you to transmit audio from any SIP device to an analog public address system: amplifier, preamplifier, power unit... The equipment is configured from a web server and powered by PoE or by a 5 V DC source. It has several audio outputs, one direct to an 8 ohm speaker and 2 W power, and two to connect the public address equipment, one AUX level (0 dB) and another MIC level (-60 dB). The equipment also provides a signal to activate the priority (open collector activated in connection) and a remote control (relay) activated by DMTF from the SIP device.
This interface forms a family with the IA-20SIP, model, which includes the ability to connect a microphone or analog sound source and convert it to SIP. It is a device that allows, therefore, intercom or standard public address functions using the SIP telephony network.
