The T-7730P features a 30W digital amplifier – double the power of the standard T-7730. Ideal for larger areas, higher ambient noise environments, and applications requiring greater volume. Perfect for tunnels, large public spaces, and industrial sites.
The T-7730P is the high-power version of the T-7730 IP66 waterproof decoding terminal. With 30W of digital amplification, it delivers twice the power for larger outdoor spaces and noisier environments, while maintaining the same rugged IP66 enclosure and extreme temperature range (-35°C to 60°C).
High Power for Demanding Applications: The 30W amplifier can drive multiple speakers or cover larger areas with higher ambient noise – tunnels, industrial sites, large public parks, and transportation hubs.
Built for the Elements: IP66 rating means the T-7730P is completely dust-tight and protected against powerful water jets – rain, snow, hose-down, and high-pressure cleaning are no problem. The aluminum alloy enclosure resists corrosion and UV degradation.
Extreme Temperature Operation: Unlike standard electronics that fail below -20°C, the T-7730P operates reliably from -35°C to 60°C. Special low-temperature components ensure performance in freezing tunnels, arctic research stations, and desert heat.
Simple Network Integration: Power via PoE simplifies installation – a single Ethernet cable provides both data and power. The terminal decodes network audio streams from the T-7700 server for paging, emergency announcements, and background music.
Double the power for larger areas, higher ambient noise, and greater coverage.
Dust-tight and protected against powerful water jets. Withstands rain, snow, and hose-down.
Extreme temperature range for tunnels, arctic, and desert installations.
Corrosion-resistant, lightweight, and rugged. Built to last outdoors.

For full 30W output, a PoE+ switch (IEEE 802.3at) is recommended. Standard PoE (802.3af) can power the unit but may limit maximum volume. The 24V DC input can also be used for full power.
| Model | Type | Protection | Key Feature |
|---|---|---|---|
| T-7710 | One-key outdoor | IP55 | 500W amp, solar ready |
| T-7731 | Explosion-proof | Ex db IIB T6 Gb, IP66 | Handset, 30W ext |
| T-7732 | Industrial outdoor | IP54 | Steel casing, anti-tamper |
| T-7730 | IP66 decoding terminal | IP66 | 16W amp, -35°C |
| T-7730P | IP66 decoding terminal | IP66 | 30W amp, -35°C |
The T-7730 and T-7730P share the same rugged IP66 enclosure and extreme temperature range. The only difference is amplifier power:
| Model | Amplifier Power | Coverage Area | Best For |
|---|---|---|---|
| T-7730 | 16W | Small to medium | Pathways, small parks, close-range |
| T-7730P | 30W | Large areas, high noise | Tunnels, large parks, industrial sites |
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.
For maximum 30W output, use a PoE+ switch (802.3at) or the 24V DC input. Standard PoE (802.3af) can power the unit but may limit maximum volume – suitable for most speech applications, but for full output, PoE+ or DC is recommended.
