Notes

The 6200 is perfect for Eureka-147 and proposed IBOC digital systems.

Eureka was created to ensure the delivery of near-CD quality audio over radio. Trouble is, near-CD quality transmission alone won't solve real world challenges such as maintaining source-to-source consistency between programs, not to mention achieving dial dominance.

Can the OPTIMOD-DAB 6200 be used for analog services?

If you're like most broadcasters, you'll be simulcasting analog and digital transmissions during the transition to DAB. That means you'll need two processors, one for each service. But, you won't be able to use one processor for both services.

Analog AM, FM and TV require pre-emphasis. Digital broadcasting is flat, without pre-emphasis. So the tuning of analog and digital processors is different. Another distinction: The bandwidth for DAB can go as high as 20kHz. Analog FM and TV are limited to 15kHz and AM is limited to 4.5kHz to 9.5kHz, depending upon the regulating authority.

The 6200 is not pre-emphasized and has no stereo encoder for FM. While there is an analog monitor output feature, it provides a fixed level to drive a house monitor, not a transmitter. The AES/EBU output is intended to drive the digital audio encoder for subsequent transmission.
