4000W FM Digital Transmitter

4000 W FM digital transmitter in a 19" Rack. 
Composed by FTC25 exciter and FA4K power amplifier.

The FT4K 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.

Direct to channel modulator delivers superb signal quality and crystal clear sound with unrivaled performance.

Remote Control

The FT4KFM 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

RDS encoder comes with a web protocol that is compatible with most of the radio automation software. This allows real-time broadcasting song/singer information automatically.

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 FT4K FM digital Transmitter includes multiple backup audio sources (analog audio input, 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

FT4K 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 the specified email addresses and phone numbers.

1+1 Redundancy System

The FT4K FM digital Transmitter is ready for 1 + 1 backup. By connecting a spare device with a coaxial switch, it enables the broadcast to continue uninterrupted in the event of any failure. Identification of spare devices and connections are made easily. The whole control system comes in the transmitter internally. In case of failure of the device defined as master, automatic switching to a Slave device is provided.
