Microwave Service Corporation Block Down Converters

Digital COFDM and analog transmissions converter
Microwave Service Corporation
Booth C6419
Block Down Converters: Available in the 2.0-2.7GHz band as well as the UHF bands (450-850MHz), Microwave Service Company's block down converters are designed to convert digital COFDM and analog transmissions to their respective signal range. The converter is a single conversion BDC with low phase noise and high linearity. Its front end features an LNA and ceramic filter that delivers a 3.5dB noise figure with a minimum conversion gain of 24dB. The UHF model also delivers a 3.5dB noise figure with an overall typical conversion gain of 24dB. DC power can be supplied locally or remotely via the coax to the IF output to both versions.

Messagecasting software add-on
Broadcast Electronics
Booth C1628
TRECast: Broadcast Electronics' Message Manager suite marketed under The Radio Experience (TRE) no offers new functions for RBDS, HD Radio, the Internet and Twitter. TRECast is a tool for creating instant unscheduled messages such as weather warnings, news alerts, or even live contest details to be delivered instantly to a single station or group of stations. These messages can be archived to a message clipboard for immediate access by announcers at any time, and from any station in the network for redistribution on RBDS, HD Radio, the Web or Twitter. This is in addition to TRE's new social network tagging capabilities, giving listeners the ability to receive a station's now playing data as well as earmark songs for purchase through the station's social networking feeds such as Twitter and Facebook. Compatible with BE's AudioVault and most other major automation systems, TRE messagecasting software enables operators to schedule text messages in much the same way they would schedule music, with a complete set of tools for generating and tracking advertiser, as well as promotional messages.

ATI Group MCDA-208/WC106

Studio master clock sync generator
ATI Group
Booth C1720
MCDA-208/WC106: The Model MCDA-208/WC106 contains an ultra-low jitter 192kHz studio master sync generator, two independent 1¡Á4 AES/EBU digital audio distribution amplifiers and a 1¡Á6 clock distribution amplifier. It is designed to give studios centralized control over their digital audio signals. When used as a studio master clock, the MCDA can generate an exceptionally stable 44.1, 48, 88.2, 96, 176.4 or 192kHz clock reference for the purpose of synchronizing all digital equipment. Automatic fallback allows external sync signals to be used, with the internal generator providing backup if external timing is lost.

AES digital to analog converter
Booth C4342
AESDA: The AESDA provides AES digital-to-analog conversion while providing diagnostic analysis of the incoming digital signal to help in troubleshooting signal faults. It features 110ohms balanced and 75ohms unbalanced inputs. Dual function level meters display either digital input signal level or analog output level. Dual function LEDs display digital input information or signal condition/fault type. It also features separate balanced XLR and 3.5mm headphone outputs; each output has its own volume control.

Tascam DR-2d

Portable recorder
Booth SL1717
DR-2d: The DR-2d is a portable digital recorder that brings high-resolution recording to a compact package. It offers up to 96kHz/24-bit audio resolution, capturing WAV or MP3 files to SD Card media. The new stereo condenser microphone design has a 74dB signal-to-noise ratio for dynamic recordings. The dual recording feature prevents overload by recording a second track at lower level, ensuring recordings won't be ruined by distortion. The DR-2d offers variable speed audition to slow down music without changing the pitch. A metronome and digital effects are also included, as well as an overdub feature for sound-on-sound recording.

Four-bay broadband FM antenna
ERI-Electronics Research
Booth C2032
Rototiller Axiom: The four-bay Axiom master FM antenna is a light-weight option as a main or auxiliary FM antenna for multiple FM stations. It has been used to provide backup FM transmission facilities for multiple FM stations in a single market area and as an emergency standby that can be deployed to restore service following a facility disaster.
