What a PA system includes, which architecture suits which building, what the protocols mean, and how to get a device schedule. Written by the people who build the equipment.

Company

Who is EASTVO?

EASTVO is the brand of Guangzhou Eastvo Intelligent Technology Co., Ltd., a manufacturer of public address systems founded in Guangzhou, China in 2007. The company designs and builds loudspeakers, SIP network audio, Bluetooth active speakers, amplifiers, voice alarm and microphones, and holds full import and export qualification.

Where are the products manufactured?

In Guangzhou, Guangdong, China. Assembly and burn-in are in-house: every unit is aged on the test rack before packing, which is the practice that sets the field failure rate rather than the datasheet numbers.

How many models does EASTVO offer?

231 models across six ranges: 91 loudspeakers, 18 SIP network audio products, 25 Bluetooth active speakers, 55 amplifiers and peripherals, 8 voice alarm products and 34 microphones.

Does EASTVO publish data sheets and a catalogue?

Yes. Every model has its own page with specifications taken from the factory data sheets, and there is a 2026 brochure as a PDF. Both are free to download from the site without registration.

Choosing a system

What is the difference between a SIP network PA and a traditional 100V line PA?

A 100V line system sends amplified audio down a two-core cable and each speaker taps off it through a transformer. A SIP network system puts each speaker on the LAN, powered by PoE, and routes audio as data — which means zones are software settings rather than cable sections, and one cable replaces signal and power.

Which system suits a school?

A SIP network system, in most cases. Classroom paging, scheduled lesson bells, exam quiet zones and help-point intercom all sit on the existing campus LAN, and a new teaching block is covered by adding speakers rather than replacing the controller.

Which system suits a shopping mall or office building?

Either a SIP network system or a 100V line system with a matrix controller, depending on the age of the building. Both give zone control for background music, welcome notices, parking guidance and emergency override; the network option wins where cabling is being renewed anyway.

Which system suits a factory, port or rail platform?

A network system with IP66 horn loudspeakers for the open areas, plus 100V line for existing buildings. Horns are chosen for long throw over high ambient noise; the IP66 rating is what keeps them alive in rain, dust and temperature swings.

Technical

Do EASTVO speakers support PoE?

The SIP network range does, on IEEE 802.3af or 802.3at depending on the model and the output level. PoE is what allows one Ethernet cable to carry power, audio and control to a ceiling or wall speaker with no local supply.

What protocols are supported?

SIP for the network audio range, ONVIF for integration with video and alarm platforms, Dante on selected models for sites that already run a Dante network, and PoE 802.3af/at for power. Analogue ranges run on 100V line or 8 ohm.

How are evacuation broadcasts triggered?

Through the alarm API or a dry contact from the fire panel. The controller overrides background music and scheduled audio, and plays the evacuation message to the zones mapped to that alarm, with speaker lines and standby batteries supervised.

Can an EASTVO system be expanded later?

Yes. Adding a building means adding speaker endpoints on the network, or tapping more speakers onto the 100V line; the controller and the amplifiers do not have to be replaced for a normal site extension.

Ordering

How do I get a quotation or a device schedule?

Send the floor plan, the ceiling heights and the rooms to be covered to sales@eastvopa.com. A device schedule, a cable plan and a quotation come back within two working days.

Can EASTVO supply documentation for a tender?

Yes. Model pages carry the specifications used most often in tenders, and data sheets, the catalogue PDF and system descriptions are available on request before a bid is submitted.

Do you work with system integrators and distributors?

Yes. EASTVO supplies system integrators and distributors in four key regions, with local commissioning support on projects. The company started as a component distributor in 2007, so the integrator's view of a project is not new to it.

What if I cannot find the model I need?

Ask. The range covers source to speaker across six categories, and a specification that is not on the site can usually be matched to the closest model or quoted as a variant.
