A High-Quality Network Solution for Your DAC to Maximize Music Streaming Enjoyment With TEAC's unwavering commitment to exceptional sound quality and intuitive operability, the NT-507T takes music streaming enjoyment to a new level. As a network streaming transport in the Reference 500 Series designed exclusively for USB digital output, it pairs seamlessly with your existing DAC, such as the UD-507, featuring TEAC’s proprietary discrete “TRDD 5” DAC to deliver reference-grade sound from online streaming and locally stored NAS audio sources. Driven by the advanced TEAC Network Engine G4, the NT-507T is engineered from the ground up with sound quality as its highest priority. A large linear power supply replaces noise-inducing switching circuits, ensuring dynamic, natural, and fluid sound reminiscent of vinyl playback. Network connectivity is equally versatile, offering Ethernet RJ45, SFP optical input, and Wi-Fi 6 support. Its high-fidelity USB output, equipped with an independent power supply section, guarantees pristine signal transmission to your DAC. User experience has been carefully refined for today’s streaming lifestyle. The NT-507T integrates smoothly with OpenHome-compatible apps such as TEAC HR Streamer, and its USB Volume Function lets you control the volume of connected USB DACs or preamps directly from the app. It supports leading high-resolution streaming services including Qobuz, Spotify, TIDAL, and TuneIn, and features a dedicated Roon Ready mode for the most demanding audiophiles. Two USB ports also allow direct connection of flash drives, HDDs, or SSDs, enabling the NT-507T to serve as a simple music server (NAS). Powerful and Incredibly Clean. The Next-Generation “TEAC Network Engine G4The NT-507T features the TEAC Network Engine G4, a fourth-generation network streaming engine that encapsulates TEAC's high-fidelity audio technology. The NT-507T provides noiseless optical network connectivity and features a powerful CPU and ample RAM to comfortably handle high-resolution formats like DSD 22.5 MHz. Driven by TEAC's powerful proprietary linear power supply, the G4 engine delivers reference-grade sound that defines the next generation of network playback. Three Types of Network ConnectionsThe G4 engine integrates an intelligent network switch and supports two types of wired LAN connections (Ethernet RJ45 and SFP ports), as well as Wi-Fi 6 wireless connectivity. Connecting via SFP optical modules and fiber optic cable ensures complete isolation from network noise, guaranteeing the cleanest signal path. The SFP port can also be used with Direct Attach Cable (DAC) for metallic connections if preferred. Wi-Fi 6 provides stable, high-speed wireless operation and can be manually disabled when you use wired connections*.*Wired LAN (RJ45/SFP) and Wi-Fi connections are switchable, so they cannot be used simultaneously. Standard Wiring Configuration Wi-Fi 6 Connction High Quality Network Wiring with Optical Switch High Quality Network Wiring with Fiber Media Converter A Linear Power Supply Delivers Dynamic and Naturally Expressive Sound The TEAC Network Engine G4's high-fidelity playback is supported by its high-quality, powerful linear supply system. This system comprises a toroidal power transformer selected for sound quality, large custom capacitors, and multiple discrete DC regulator circuits. This design eliminates noise-induced sound thinning. It produces a musical presentation reminiscent of analog playback — rich, dynamic, smooth, and naturally expressive. Four Independent Power Supplies/Low-Feedback DC RegulatorsThe toroidal power transformer has four separate windings: one for the network engine, one for the USB output circuit, one for Wi-Fi circuit, and one for the display LEDs. Isolating the power circuits eliminates mutual interference, improving sound quality. Each power section uses a discrete "low-feedback DC regulator" configuration. Reducing feedback results in a fresh, open, and dynamic sound. Audiophile-Grade USB Output TerminalSupporting DSD 22.5MHz and PCM 768kHz/32-bitThe NT-507T features an audiophile-grade USB (Type A) output terminal supporting DSD 22.5MHz and PCM 768kHz / 32-bit digital formats. Powered by a dedicated supply circuit connected to an independent transformer winding, it outputs a pure and stable digital signal.The NT-507T also has a "USB Volume Control" function that allows users to adjust the volume of the connected USB DAC/preamp via the app. The volume is controlled at the receiver, maintaining the full-scale output of the NT-507T. This feature strikes a balance between quality and ease of use without compromising the bit resolution of the digital source. Music Server FunctionalityThe NT-507T extends network audio enjoyment beyond online streaming services to high-resolution file playback from NAS devices and USB storage. Two USB ports – Type A and Type C – allow direct connection of flash drives, HDDs, or SSDs, enabling the NT-507T to operate as a simple NAS-style music server.
