The Lotoo LTTP WT-2 Lossless Audio Transmitter is a compact wireless Hi-Res audio transmitter that uses Lotoo's proprietary LTTP (Lotoo Teleportation Protocol) technology to deliver lossless digital audio transmission from smartphones or other sources to Lotoo devices, such as the PAW GT2 or Mjolnir players. This solution is ideal for audiophiles who want to stream lossless or even 96 kHz/24-bit content without Bluetooth compression, while keeping latency low. Its compact dongle design makes it perfectly portable, compatible with Type-C or Lightning adapters for most platforms.
Technological Foundation
The WT-2 utilizes Lotoo's LTTP protocol, operating at a maximum transfer rate of 1.5 Mbps in the 2.4 GHz frequency band, enabling lossless transmission up to 48 kHz/24-bit, and adaptive compression for up to 96 kHz/24-bit beyond that. Unlike Bluetooth, this is a dedicated protocol that eliminates signal dropouts, noise, or compression losses, pairing plug-and-play with the receiver—no app or complex setup required. Precise clock management and adaptive bandwidth control ensure a stable connection up to 10-30 meters indoors, matching the sound quality of wired or local playback.
Features and Benefits
The transmitter starts in automatic pairing mode (indicated by red-blue flashing), where the receiver (e.g., PAW GT2) uses the LTTP-XXXXXX ID from the back panel, with blue light confirming a successful connection. It supports PCM and Hi-Res formats (from FLAC, WAV, DSD-compatible sources) and draws power via USB from the source—no separate battery or charging needed. Its small size (65 x 19 x 9.5 mm, 10.5 g) fits discreetly on any smartphone, PC, or streamer, making it perfect for streaming services like Tidal in the Lotoo ecosystem without compromising audio quality. User feedback highlights transparent, dynamic sound with textured bass and no added noise or delay.
