Audio Equipment
DSG is a digital stereo coder and RDS able to interface to any transmitter in common use around the world.
The MULTI CODER DSG (Stereo and RDS generator) uses a digital control circuit to produce a system with an outstanding performance, high stability and total control of the signal: amplitude and phase are both adjustable to ensure optimal matching with all transmission systems and the best possible stereo separation.
The RDS
setup is also available via satellite.
