Lightspeed T25 Classroom Audio System (Amplifier + Clearmike)
The Lightspeed T25 is an installed classroom audio system built around a compact wireless amplifier hub. It delivers clear, even distribution of the teacher's voice, student voices and multimedia audio throughout the room, connecting to your ceiling or wall speakers for a permanent, professional install. The T25 is Lightspeed's successor to the long-running 975 amplifier, adding point-to-pair wireless, digital multimedia inputs and built-in integration with school life-safety systems.
Why schools choose the T25
Clear, even audio for the whole room — distributes the teacher's natural voice and multimedia evenly through ceiling or wall speakers, so every student hears every word.
One connected hub — brings the teacher microphone, classroom multimedia and student microphones together through a single amplifier.
Built for permanent installation — ideal for new builds, refurbishments and room additions where a fixed, out-of-the-way system is preferred.
Safety built in — integrates with your existing paging, fire and life-safety systems so critical announcements are never missed.
Point-to-pair wireless with the Clearmike
The T25 runs on Lightspeed's Access Technology (1.9 GHz) for longer wireless range with no Wi-Fi interference. Pairing is instant — simply point the Clearmike at the T25 to connect, so teachers can move between rooms or add components in seconds. The Clearmike wearable microphone includes programmable buttons and an alert button for one-touch safety notifications, plus 2-way USB audio to connect students learning from home.
Built-in life-safety integration
Paging: automatically mutes the instructional audio when a classroom announcement is broadcast.
Fire alarms: mutes the instructional audio when the fire alarm is activated.
Alert notifications: the teacher can trigger an alert directly from the microphone via the T25's contact-closure output.
Build your T25 system
The T25 is a modular system — choose the components to suit each room:
T25 amplifier + Clearmike teacher microphone — the core of every system
Speakers — TCS multimedia ceiling speakers, DRQ drop-ceiling speakers or WMQ wall speakers, selected to suit the room size and ceiling type
Student microphones — add Sharemike or T3 microphones so students can be heard clearly across the room and by remote peers

Lightspeed Topcat Ceiling Classroom Audio System (with Clearmike)
The Lightspeed Topcat is an all-in-one, ceiling-mounted classroom audio system that distributes the teacher's voice and multimedia evenly across the whole room. Its hybrid speaker design pairs a flat-panel speaker for clear, intelligible speech with a cone speaker for full-range multimedia sound — all in a single unit that lays neatly into the ceiling. With wireless audio integration and simple installation, the Topcat suits both new builds and existing classrooms.
Why schools choose the Topcat
Full-range hybrid audio — a flat-panel speaker spreads speech evenly to every seat, while a dedicated cone speaker delivers rich multimedia sound.
Seamless ceiling design — disappears into the ceiling for a clean, clutter-free room, with no speakers taking up wall or floor space.
Lower installation cost — wireless connectivity to microphones and multimedia removes the need for long, expensive cabling runs.
Even coverage for the whole class — every student hears the teacher clearly, wherever they sit.
