The T-7782 features 8GB of onboard storage for pre-loaded audio messages. In the event of network failure, the speaker can continue playing scheduled announcements, emergency alerts, or background music from its internal storage – ensuring critical communications are never interrupted.
The T-7782 is a rugged, weatherproof IP column speaker designed for outdoor applications where reliability and audio quality are paramount. With an IP66 rating, aluminum alloy construction, and a 30W Class D amplifier, it delivers clear, intelligible audio in parks, campuses, industrial sites, and transportation hubs.
Built for the Elements: The IP66 rating means the T-7782 is completely dust-tight and protected against powerful water jets – rain, hose-down, and harsh weather conditions are no problem. The aluminum alloy enclosure resists corrosion and UV degradation.
Offline Playback – Network Independence: The integrated 8GB SSD allows pre-loading of audio messages. If the network goes down, the speaker continues to play its scheduled content from internal storage. Critical for emergency systems and remote locations with unreliable connectivity.
SIP Protocol Support: Native SIP support enables direct integration with VoIP phone systems, intercoms, and unified communications platforms. Make announcements from any SIP-enabled device – desk phone, softphone, or intercom.
Solar Compatible: The 24V DC power input allows connection to solar power systems, making the T-7782 ideal for off-grid locations such as parks, remote industrial sites, and rural deployments.
Dust-tight and protected against powerful water jets. Withstands rain, hose-down, and harsh weather.
Onboard storage for offline playback. Critical announcements continue even without network.

| T-7784 | 60W | IP66 | 8GB SSD | Yes | 24V DC |
| T-7784H | 40W | IP66 | No | No | 24V DC |
The T-7782 (30W) and T-7784 (60W) share the same IP66 rating, 8GB SSD storage, SIP support, and solar compatibility. Choose T-7782 for smaller areas or lower volume requirements; choose T-7784 for larger spaces or higher ambient noise.
Both models: IP66 • Aluminum alloy • Offline playback • SIP • 24V DC solar compatible
IP66 rating: 6 = dust-tight (no dust ingress), 6 = protected against powerful water jets (heavy seas, hose-down). Suitable for outdoor use in all weather conditions, including rain, snow, and cleaning with pressure washers. Not suitable for submersion.
Load audio files onto the 8GB SSD via T-7700RP software or direct USB upload (via service port). Create playlists, schedules, and priority levels. The speaker automatically falls back to offline playback if network connectivity is lost.
