ONAIR, 300 W Compact FM Transmitter

FTC300-21 FM compact transmitter is manufactured with state-of-the-art and highly efficient LDMOS transistors which reduce the operating, cooling and maintenance costs and have a longer life span.

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

Remote Control

FTC300-21 FM compact 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(OSC). 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, if you wish it sends you a warning message and activates the backup audio service.

Audio Backup

FTC300-21 FM compact transmitter contains multiple redundant 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

It has an integrated audio processor that can decode Shoutcast, Icecast, HE-AAC v1/v2, MPEG-1 Layer 3 compressed audio streams, OGG compressed audio streams, and lossless uncompressed PCM streams, over IP networks. Even with behind NAT connections, 3G/4G connections, and Firewalled connections, FTC300-21 provides high sound quality without the need for user interference.

Integrated Audio Player

FTC300-21 FM compact 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.

1+1 Redundancy System

FTC300-21 FM compact transmitter is ready for a 1+1 backup system. 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.
