Broadcast Electronics (Marti) GRX-900S Marti G-Series STL Receiver

Professional STL Receiver for Broadcast Audio Links

The Broadcast Electronics Marti GRX-900S is a professional STL receiver designed to reliably receive MPX, mono, and composite stereo signals in broadcast transmission chains. It serves as the receiving end of a Marti G-Series Studio Transmitter Link, delivering stable, high-quality audio from studio to transmitter site.

Supports MPX Mono and Stereo Signal Paths

This STL receiver is built to handle a wide range of broadcast audio formats, including MPX, mono, and left and right stereo outputs. It allows engineers to route composite stereo or discrete audio signals directly into transmission or processing equipment, supporting flexible broadcast workflows.

Field Tunable Frequency Flexibility

The GRX-900S offers field-tunable operation within a 20 MHz range of the original ordered frequency. This capability allows broadcasters to adapt to frequency coordination changes or site requirements without replacing hardware, helping maintain long-term system usability.

Digital Control and Remote Management Capability

Full digital control is integrated into the GRX-900S, including an RS232 port for remote monitoring and configuration. Engineers can manage receiver settings, status, and diagnostics from control systems or external automation platforms, supporting unattended or remote transmitter sites.

Reliable RF Connectivity and Power Options

A Type N-Female RF connector provides secure and low-loss RF input connectivity suitable for professional STL installations. The receiver supports a wide input power range from standard AC mains as well as DC battery backup systems, ensuring continued operation during power interruptions.

Designed for Broadcast Transmission Environments

Built for continuous operation in transmitter facilities, the GRX-900S is engineered for reliability, signal integrity, and ease of integration with Marti STL systems. It is suitable for AM, FM, and composite stereo broadcast applications where dependable audio transport is critical.
