Audemat Audemat
RDS Encoder Silver

High quality and spectral purity


All of our RDS encoders use surface-mount components and multi-layer circuit boards with a large ground plane. This enables us to keep high frequency signal paths very short, and provides inherent shielding. The result is measurably better performance than other types of construction. All our encoders construct their data digitally, using Wavelet technology at a sample rate of 912 kHz.

This prevents any possibility of spurious signals affecting audio quality. Unlike some competing units, modulation of the data onto your composite signal is also in the digital domain for purity and freedom from interference. There are no analog pass band filters, so there’s no possibility of drifting or degradation of the audio signal.


Reliable


Audemat products are designed for continuous on air operation and are known for their reliability. All of our RDS encoders feature solid state memory and have no moving parts. Configuration is retained through power outages. Every setting is controlled through software: there are no potentiometers or trimmer capacitors to age or need realignment. The FMB80 also includes a separate decoding system so you can monitor the integrity of your RDS signal and keeps a downloadable log to aid in troubleshooting and maintenance.

The FMB series comes with a 2 year warranty and the Silver RDS has a 1 year warranty.
