FT8K-D - 8 KW 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.

FT8K-D - 8 KW FM Digital Transmitter equipped with Analog Audio, AES/EBU, MPX, I2S inputs. Which are converted to digital signals and modulated in an FPGA with excellent software algorithms to FM band with the extremely low noise level.

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

Remote Control

The FT8K-D - 8 KW 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 the device via Onair Service Center even in the rural areas which have a mobile phone signal.

Built-in RDS Encoder

The 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

FT8K-D - 8 KW FM Digital Transmitter’s silence detector, detects silence on the inputs according to the specified threshold level. It can either notify you and can trigger the audio backup feature.

Audio Backup

Supporting several types of Backup sources, upon audio loss, FT8K-D - 8 KW FM Digital Transmitter will switch between the sources (Analog Audio Input, AES/EBU, MPX, I2S, IP Audio Client, Integrated Audio Player) on the prearranged configurations (Silence time, silence level).

IP Audio

FT8K-D - 8 KW FM Digital Transmitter 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, FT8K-D - 8 KW FM Digital Transmitter provides high sound quality without the need for user interference.

Integrated Audio Player

FT8K-D - 8 KW 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 approximately 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.

N+1 Redundancy System

FT8K-D - 8 KW FM Digital Transmitter is ready for the N+1 Redundancy System. The backup device automatically goes online immediately, when the master goes offline.

Automatic audio source selection

When the L&R audio source is cut off, MPX, AES/EBU, IP or Audio backup (internal SD card) can be selected automatically in FT8K-D. Audio backup (internal SD card) can be selected in FT8K when the L&R audio source is cut off.

Printer port

It is used to print out the event logs

N+1 Redundancy system

FT8K-D : Maximum 7+1 , FT8K : 1+1 only

GPIO

when temperature or humidity is high you can run air-condition automatically

RS485

It is to communicate between Onair transmitters

RS232

It is used to program the internal RDS via satellite or to get print out of events

USB

It is used to update the software of the control system

Interlock

It is used to stop the transmitter in case of an emergency like a fire inside the transmitter station
