The answers appear below.
Sennheiser Electronic MKH 800
Based upon Sennheiser's MKH 800, the MKH 800 Twin offers polar pattern switching after the recording session. The MKH 800 Twin can be thought of as a multi-pattern microphone without the pattern switches. It is equipped with both front and back capsule outputs. In a standard multi-pattern mic, the pattern of the mic is derived by adding and subtracting the back capsule. Because of the MKH 800 Twin's dual outputs you can simply plug both of these capsules into a DAW or recorder and create the pattern desired during mix-down. The Twin is ideal forbroadcasting and field recording.

Audio Science ASI8914
HD-Radio tuner adapter
The ASI8914 is a universal, full-length PCI card that contains four HD-Radio/AM/FM tuners and is designed for us in HD-Radio broadcast monitoring and auditing. Each tuner may be set to an independent analog or HD-Radio station. The audio from each tuner is presented to the computer host as a mono or stereo record stream that may be accessed through a 32-bit PCI bus master interface. An F connector feeds RF signal from an external antenna to all tuners on the ASI8914. Each tuner may also be fed from an external antenna input. An HD50 connector makes available the mono or stereo line level audio of each tuner output. Recording formats include PCM, MPEG-1 layer2 and MP3. Each tuner can also decode and stream the HD-Radio Program Associated Data data and RDS/RDBS data for analog FM. HD-Radio multi-cast is supported, allowing the audio and PAD stream to be switched between the Main Program Service and Secondary Program Services under software control.
Inovonics Model 720
The 720 is a third-generation product in the Inovonics line of RDS encoding and decoding products. A front-panel LCD screen allows the user to scroll through and confirm all setup and operating parameters without the need for a computer on site. Incoming data from station automation can be seen on the fly, and scrolling song titles and other messages are displayed exactly as they are seen by listeners. The 720 automation command set remains compatible with earlier models for seamless integration along existing encoders, and a new no headers mode allows use with unformatted, satellite-streamed song title feeds. Intuitive, self-guiding software, built-in data diagnostics and transmission safeguards make installation virtually foolproof.
