OSE30 - Omnicast Stereo Encoder
The OMNICAST OSE30 Digital Stereo Encoder is a fully compliant broadcast specification unit for FM radio.
The OSE30 performs digital encoding of left and right channels to produce an accurate and alignment-free
MPX Stereo signal.
The pilot is crystal locked with a digital divider.
A pilot phase control allows fine adjustment of separation and the MPX level control provides output levels to
suit any exciter.
The OSE30 is housed in a 1RU rack case with either 600ohm balanced or 47k RCA inputs.
