BTSC-100

Aural BTSC Demodulator

The BTSC-100 is an aural TV demodulator that decodes a 4.5 MHz or aural composite input into balanced left and right BTSC stereo audio and Secondary Audio Program (SAP) outputs. When the 4.5 MHz input is used, the unit will provide aural composite in addition to the standard audio outputs. The BTSC-100 is designed for use in applications where the existing audio is only available in 4.5 MHz or aural composite formats, and where fully demodulated stereo and SAP audio is required. These types of situations include local ad insertions, announcements and alerts. The small size of the BTSC-100 (only 1/3 RU wide) means the unit can be put almost anywhere. Using the optional DAT-1 rackmount tray, up to three BTSC- 100 units can be mounted in a single rack unit of space.
