30W High-Power Amplifier

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.

Product Overview – T-7730P

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.

High-power outdoor audio

Weather-sealed

Connections & I/O
  • Ethernet: RJ45, 10/100, PoE (802.3af/at), weatherproof gland
  • Speaker output: Screw terminals for external speaker (4-8Ω)
  • DC input: 24V DC (for non-PoE installations)
  • Aux input: Not available (pure decoder)
  • Cable entry: Weatherproof gland for Ethernet/DC
PoE+ Recommendation for 30W

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.

System Compatibility – T-7730P

Required Controllers & Software
  • T-7700 / T-7700A / t-7700h – Server hardware
  • T-7700RP / T-7700RU – Broadcasting management software
  • PoE+ switch (802.3at) or DC 24V power supply
  • External speaker (4-8Ω, weatherproof recommended)
Compatible Speakers
  • T-7782 series: Outdoor column speakers (30W/60W)
  • T-7707 series: Wall-mounted speakers (indoor/outdoor)

T-7730 vs T-7730P Comparison

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 – What It Means

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.

Power Supply Note

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.

Typical Installation – Highway Tunnel

T-7730P (wall-mounted) driving weatherproof speakers in tunnel

Multiple T-7730P units placed throughout tunnel, connected via PoE+. 30W amplifiers overcome traffic noise for clear emergency announcements. Operates reliably at -30°C in winter. IP66 protection against tunnel washdown.
