Overview
Belar FMHD-1, Precision Digital FM/HD Stereo Monitor-Analyzer
The Belar FMHD–1 is a state of the art HD Radio monitor designed to support the needs of today’s broadcaster well into the future. The monitor decodes the HD Radio signal and analog FM signal simultaneously displaying HD Radio status, data, time alignment, and configuration information, as well as total, rds, pilot, L, R, L+R and L!R metering and RF spectrums. The FMHD–1 is a two rack unit with a 640 x 240 wide viewing angle color LCD display and rotary encoder providing a detailed, clean and simple user interface.
The FMHD–1 currently supports monitoring multiple audio streams and simultaneous monitoring of four streams with optional Decoder Expansion Board and additional decoders. The units 8, user assignable, analog audio outputs, and 3 assignable AES-3ID outputs provide support for a wide variety of broadcast scenarios including multi-casting and Surround Sound
Please note, unit ships with ONE DECODER. Unit supports up to 3 additional Decodes.
