The Siel EXC30 transmitters enhances the capabilities of the existing EXC25 FM transmitter.
The EXC30 is a 30 W direct-synthesis frequency-agile FM transmitter that provides the basic features of the EXC25 with the addition of a more powerful controller to improve local and remote control capabilities. Control is possible either via the front-panel interface or a remote PC.
It has a separate auxiliary SCA/RDS channel input, balanced/unbalanced audio and MPX input, optional AES/EBU digital audio input and multiplex modulation LF output. Frequency selection is in 10 or 100 kHz steps.
The EXC30 also offers real-time clock and date with backup battery and password protection for critical data and programming.
Available options include a stereo encoder board, an internal GSM modem and USB, 10baseT Ethernet and RS-485 ports. These ports facilitate the setting of internal parameters such as power, input sensitivity and frequency, as well as help verify system status elements, such as modulation, direct and reflected power on the antenna, temperature and alarms.
