The FT300-D - 300 W FM digital Transmitter is manufactured with state-of-the-art and high-efficiency LMMOS transistors which lower the operating, cooling and maintenance costs and are more durable.

The FT300-D - 300 W FM digital Transmitter is equipped with analog audio, AES/EBU, MPX, I2S inputs.  All of them are processed in FPGA and converted to digital signals and FM waves are produced with the minimum noise level.

Direct to channel modulator provides very high signal quality, crystal clear audio and unbeatable performance.

Remote Control

The FT300-D - 300 W FM digital Transmitter comes with cloud-compatible remote control software with a simple interface. All the features of the device can be viewed and controlled via the built-in web server or OnAir service center. With 3G/4G USB support, the device can be easily controlled even in rural areas with mobile phone signal thanks to cloud support.

Built-in RDS Encoder

Thanks to the built-in RDS encoder and the special web protocol we have developed, we work with most of the radio automation software and automate the release of the song and artist name.

Silence Detector

Thanks to the built-in silence detector, it detects the sound interruption in the broadcast, sends you a warning message if you wish, and activates the backup audio service if you wish.

Audio Backup

The FT300-D - 300 W FM digital Transmitter has multiple redundant audio sources (analog audio input, AES/EBU, MPX, I2S, IP audio, built-in audio player). In the event of audio interruption, changing the audio sources according to your preference ensures that your broadcast always has a sound.

IP Audio

With the built-in audio Analyzer, Shoutcast, Icecast, HE-AAC v1/v2, MPEG-1 layer 3 compressed audio streams, OGG compressed audio streams, and uncompressed PCM audio streams can be analyzed over IP networks. It works easily anywhere with internet access, even on firewalls or custom routed networks, without the need for high audio quality and human intervention.

Integrated Audio Player

FT300-D - 300 W FM digital Transmitter supports MP1, MP2, MP3, OGG, AAC, HE-AAC, MPEG-4 ALS, OGG Vorbis, FLAC, Musepack, Speex, and wave file types. With the built-in 8 GB memory, you can store approximately 1000 hours of audio recording.

E-Mail and SMS Notifications

In case of any warning or error, the device sends E-Mail and/or SMS notifications to specified email addresses and phone numbers.

N+1 Redundancy System

The FT300-D- 300 W FM digital Transmitter is ready for the n+1 backup system. Identification of spare devices and connections are made easily.
