		Click for larger view		MODEL 619 DIGITAL INSERTION UNIT Interrupts a single AES/EBU stream and inserts an analog (L,R) or AES/EBU stream. A typical installation is insertion of EAS information from a TFT EAS Encoder/Decoder into a digital program audio stream. *See Model 629 Datasheet
		Click for larger view		MODEL DSS93 DIGITAL SUBCARRIER SYSTEM This system provides four 15 kHz CD quality audio channels and up to two 3 kHz voice grade channels (or a data channel) on a single subcarrier for wideband microwave and satellite applications. Provides 80 dB SNR audio performance with 600 kHz channel spacing. DSS93 System Datasheet (.pdf, 772KB)
				MODEL 8500D/8501D DIGITAL SUBCARRIER GENERATOR AND DEMODULATOR This composite subcarrier system transmits the entire BTSC composite baseband– Stereo, SAP, and Pro Channel– from the studio to the transmitter site utilizing only one microwave subcarrier frequency. The wideband signal “fits” into the 700 kHz subcarrier space normally occupied by ordinary monaural subcarrier systems without interference or sacrifice in performance. Can be used to feed 4.5 MHz to a cable system. *See DSS93 System Datasheet
