How to connect existing devices: verify first, no promise of plug-and-play

Register existing devices

Record the model, hardware version, firmware, interface, frequency band, power, and original system protocol. TP-WTG, TP-WSD, and TP-WTA are listed only as adaptation verification targets and do not imply interoperability across the entire series.

Verify TP-CTS Podium

TP-CTS03, 07, 10, 11, 12, and 06 are for compatibility reference. Check the pickup, speaker, and conference interfaces unit by unit; supplement with gateways, conference terminals, or software as necessary. No commitment is made that joining a conference can be achieved by upgrading alone.

Retain reusable links

Existing analog amplifiers and speakers can be evaluated for TP-DN05 or TP-DN10 integration; confirm levels, impedance, constant-voltage mode, and protection measures. Downlink decoding integration does not automatically grant legacy systems uplink capability.

Form a compatibility conclusion

Complete broadcasting, amplification, return transmission, conferencing, and network disconnection drills in the model classroom; record reusable items, modification items, limitation items, and test versions, then finalize the procurement list.

These devices cannot be defaulted to full two-way classroom nodes.

Device Type	Adaptation Boundary	Engineering Verification
TP-DN05 Gateway, TP-DN06 Matrix, TP-DN07 Linkage Interface	Undertaking interface or control functions is not equivalent to an all-in-one conference venue with sound pickup and amplification.	Protocol, Electrical Isolation, Linkage Logic, and Fault Status
TP-DN09 Collector, TP-DN10 Decoder	They respectively focus on audio source input and downlink output, and it cannot be assumed that both support bidirectional participation in meetings.	Encoding Format, Line Level, and Upstream Supplementary Equipment
TP-DN11 to TP-DN14 Outdoor or Public Area Speakers	The return transmission, network module, and power supply vary by model; when there is no independent pickup, on-site audio cannot be captured.	Protection, Load, Network, Installation and Optional Accessories List
TP-DW04, TP-DW05 Microphones and Sets	By working with matched nodes, it cannot replace a network conferencing terminal on its own.	Frequency band, receiver, two-way voice link, and call control
TP-DW07 Repeater, TP-DW08 Storage Box	Responsible for coverage extension or charging management, not an independent classroom venue	Cascade latency, power supply, microphone compatibility, and reporting functions
TP-DC02, TP-DC03, TP-DC05 peripherals	Separately supplement audio pickup, video, or display, requiring a host, interfaces, and authorization support	Compatible protocols, cable distance, video software, and power supply

How to read the specifications and images on this page

This section presents solution planning for campus broadcasting, campus conferences, and campus AI, and is not a full catalog of already-launched products. The functions and numerical indicators of the 42 newly planned models are planning targets and must be confirmed based on actual hardware, software licensing, network, acoustic environment, and test results; TP-CTS is a compatibility reference for existing products and requires model-by-model adaptation verification. Descriptions of local wireless amplification and two-way conferencing participation refer to classroom nodes equipped with the corresponding modules and fully configured, and do not mean that every speaker, gateway, or accessory has these capabilities. The images are for reference only regarding the appearance of existing products and are not proof of the actual appearance of new models.Each specification of the planned model carries a planning and testing label; capacity, power, distance, protection, latency, and AI concurrency cannot be directly used as evidence of acceptance compliance. Formal delivery shall specify the model version, verified metrics, optional items, software term, maintenance responsibilities, and test reports.

Starting from the real needs of the campus

Turn "audible" into "conversational."

Tell us the number of classrooms, network conditions, and usage scenarios, and let's determine the right broadcast, conferencing, and AI configuration together.
