4000 W FM Digital Transmitter

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

FT4K - 4000 W FM Digital Transmitter designed with the latest LDMOS transistors, which ensures high efficiency. Operational costs, heat and cooling costs, maintenance costs are reduced, and life span is increased.

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

Remote Control

FT4K - 4000 W FM Digital Transmitter is shipping with its easy to use Cloud enabled remote control system. The device can be managed and controlled via its web server and Onair Service Center. With the 3G/4G USB stick connection port, you have complete access to device via Onair Service Center even in the rural areas which have mobile phone signal.

Built-in RDS Encoder

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

Silence Detector

FT4K - 4000 W FM Digital Transmitter’s silence detector, detects silence on the inputs according to specified threshold level. It can either notify you and can trigger audio backup feature.

Audio Backup

Supporting several types of Backup sources, upon audio loss, FT4K - 4000 W FM Digital Transmitter will switch between the sources (Analog Audio Input, IP Audio Client, Integrated Audio Player) on the prearranged configurations (Silence time, silence level).

IP Audio

It has integrated audio processor which 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, FT4K - 4000 W FM Digital Transmitter provides high sound quality without the need of user interference.

Integrated Audio Player

FT4K - 4000 W FM Digital Transmitter supports MP1, MP2, MP3, OGG, AAC, HE-AAC, MPEG-4 ALS, Ogg Vorbis, FLAC, Musepack, Speex, WAVE file formats. With the 8 Gb total storage capacity, you can store approxtimately to 1000 hours of audio recordings.

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

FT4K - 4000 W FM Digital Transmitter is ready to use as dual drive system. You can connect one backup device to realize dual drive system using only one coaxial switch. All control system is ready inside the transmitter. Backup device automatically goes online, when master goes offline.
