RTW HW20918 32-Channel Ravenna AES67 AoIP Interface

Professional 32-Channel Ravenna AES67 AoIP Interface for TM9 Series

The RTW HW20918 is a professional-grade 32-channel Ravenna/AES67 Audio-over-IP (AoIP) interface designed for seamless integration with the RTW TM9 TouchMonitor Series. It provides 32 channels of digital input and output over standard Ethernet connections via dual RJ-45 ports. Built for demanding broadcast and production environments, this interface enables high-performance, low-latency audio networking using industry standards such as Ravenna, AES67, and SMPTE ST 2110.

High-Performance Networked Audio for Modern Workflows

The HW20918 brings the power of network-based audio to your TM9 system. By supporting the Ravenna and AES67 protocols, it allows professional facilities to exchange audio streams with other networked devices from multiple manufacturers while maintaining pristine sound quality. This interoperability makes it ideal for use in broadcast control rooms, OB trucks, and post-production facilities that depend on scalable, flexible, and IP-based audio infrastructure.

Precision Integration with TM9 TouchMonitor Systems

When installed in an RTW TM9, the HW20918 transforms the TouchMonitor into a fully networked metering and analysis solution. Users gain access to detailed loudness, peak, and correlation monitoring for up to 32 audio channels transmitted over an AoIP network. With the TM9’s responsive touchscreen display and customizable metering layouts, engineers can manage complex audio systems and ensure compliance with international loudness standards such as EBU R128, ITU-R BS.1770, and ATSC A/85.

Reliable Audio-over-IP Transmission with Low Latency

Designed to meet the demands of real-time production environments, the HW20918 delivers low-latency, high-precision audio transfer across IP networks. The interface supports deterministic timing using PTP (Precision Time Protocol), ensuring accurate synchronization across all connected devices. This makes it an essential component for mission-critical broadcast operations, live production, and distributed studio networks that require perfect signal alignment and reliability.

Built for Future-Proof Network Compatibility

Supporting Ravenna, AES67, and SMPTE ST 2110 standards, the HW20918 ensures future-proof compatibility within expanding IP-based ecosystems. Its flexible architecture allows integration with digital consoles, audio routers, and signal processors that share these open standards. Whether adding to an existing AoIP workflow or building a new one from the ground up, this interface provides professional versatility and long-term value.

Professional Installation for Optimal Performance

The HW20918 is a specialized hardware expansion that requires installation by an authorized RTW service center. This guarantees accurate setup, calibration, and firmware alignment with the TM9 system for optimal operation. Once installed, it provides a stable and efficient digital link for precise, real-time monitoring and audio management within any professional AoIP network.
