Transient voltage surge suppressors
Booth 1762, 2121
Stabiline TVSS series: Units in this series are suited for mission-critical and high magnitude transient exposure Category A, B, and C industrial, medical and broadcast applications. They ensure continuous on-line surge protection because of a fail-proof fuse that cannot be opened by a transient. Models are available for full rated current capacity to 300,000 amperes. Features include an advanced suppression filter assembly. Other features are all modes protection, which safeguards all electrical modes such as L-N, L-G, L-L and N-G; all copper, tin-plated bus that provides minimum impedance and eliminates wire bends; individually fused MOVs; disconnect models with safety interlock entry doors; seven-year product warranty, and availability of such options as standard; and advanced monitoring and hand held tester.
Digital audio codec
Audio Processing Technology
WorldNet Milano: Features standard and enhanced apt-X, the company's upgraded data compression algorithm, which offers a reduction in coding delay, improvements in audio quality and increased dynamic range. The Milano features four ISDN interfaces (S or U), in addition to permanent digital links, and has available audio bandwidths from 10Hz to 22.5kHz, with corresponding synchronous bit rates from 56kb/s to 576kb/s. This full duplex, multi-channel ISDN audio coded is suitable for inter-studio networking, remote/outside broadcasts and STL applications.
Broadcast Software International
Simian: This automation software, known only by the development codename Simian, is the first of a new generation of digital automation systems. Many features are still confidential, although BSI reveals that Simian incorporates advanced capabilities for self-diagnosis and repair, interstation communications, streaming spot substitution, remote control and live support. Touchscreen enabled, Simian will support tagging and simultaneous multiple playback of all professional audio file types. Simian's official launch will be at the NAB Radio Show during the BSI On The Bayou riverboat demonstration. Contact BSI for complimentary tickets.
Dual IPA upgrade: This upgrade provides parallel dual redundancy so that if a module fails in the IPA, the station stays on the air. Also offers an improvement in AM noise. Using two combined modules isolates the IPA from the PA grid at warm up. Greatly reduces the cost of repairs in the unlikely event of module failure, and modules can be repaired in the field using common parts. Better bandwidth and AM noise performance improve FM stereo and SCA performance. Stations can install the IPA upgrade kit. Kit includes full installation and operation instructions.
Numix console accessory
Selector wedge: The monitor speakers, operator headphones, guest headphones and the cue speaker are controlled from the Selector wedge. A multi-station talkback system is offered. LCD panels allow input sources and output destinations to be assigned to each fader and monitor channel. Pan/balance and optional three band EQ for each fader is controlled by the selections LCD screen. The preset system is also controlled from this screen. A bank of relays allows for remote starting of local machines. A cue in phones button is included. Two three-color LED stereo meters monitor the on-air program and speaker feed. Each meter offers simultaneous VU, true peak and peak hold.
PSC II: The front panel provides for a six-digit, ½-inch seven-segment LED display. Front panel LEDs are provided for the 16 relays; signal loss; device #1 serial data; device #2 serial data; power; control port serial data and 1 PPS. The PSC II controls functions by either scheduled time and date, time and day of week, serial port commands and remote input contact closures. Using non-volatile memory for the two serial control ports, each of the 64 control macros may have up to 32 characters, including control characters. The PSC II's non-volatile memory also contains 199 scheduled events. The PSC II is furnished with a Garmin 12 Channel GPS receiver with embedded antenna. Programming is accomplished with any non-dedicated computer and communication software.
Digital FM processor
Omega_FM: A largely software-based digital on-air processor/generator, Omega_FM offers a short and direct program signal path that keeps latency (audio delay) at a minimum. The user interface includes a no-menu front panel setup that suits a variety of applications or allows any PC to be connected for control over all processing parameters.
Digital matrix mixer
PSR1212: A highly-advanced 12x12 digital matrix mixer with audio processing. The PSR1212 uses an internal macro language and 32 user-definable presets to adapt to a variety of sound reinforcement and room-combining applications in auditoriums, stadiums, theatres, gymnasiums, hotel/convention centers, conference rooms, training rooms, and boardrooms. The PSR1212 facilitates local and remote PC setup and diagnostics, logic outputs, and gated microphone operation. Microphone inputs can be individually customized to gate on and off as you wish, while automatic gain control keeps the overall sound level consistent. Input channels one through eight can be configured as an automatic microphone mixer. The Expansion Bus network architecture allows up to eight PSR1212s and up to 96 inputs, 96 outputs, and 64 microphones to be controlled as if part of a single unit.
Analog and digital converter
Dream ADA-8: This converter provides eight channels of 24-bit, 96kHz A/D and D/A conversion. The goals of ultimate sound quality and versatility have been realized in a multi-channel format. Analog input and output sensitivity (and inter-channel balance) are software-adjustable over the entire range with 0.05dB resolution. Inputs and outputs are transformerless, electronically balanced and fully floating, to ensure freedom from noise pick-up and crosstalk. The ADA-8 avoids the effects of jitter with independent, multi-stage PLLs, featuring jitter-attenuation and clock generation and recovery. The ADA-8 has two digital I/O module slots into which a variety of modules can be fitted, including AES3 (2-speed or 2-wire), TDIF, ADAT or SDIF.
Q20/20: Addressing the power requirements of 22kW and 44kW, the Q20/20 is a single ended solid-state transmitter. Reliability is enhanced though redundancy and duplication features: multiple power amplifiers provide modular reserve. Facilities are provided for duplication of the exciter, IPA and IPA power supply and low voltage power supplies. The common DC bus is developed from parallel redundant rectifiers.
Telephone call editor
Qed: Running on a Pentium III CPU with Windows 2000 and using the Digigram PCX-924 DSP board, Qed is an editing system that is optimized for on-air recording and editing of phone calls. Scrolling waveforms follow the audio; marker points make editing simple. Left or right channels can be erased, or a bleep can be inserted independently. Ten buttons are available, with each featuring a countdown timer. Qed is balanced analog and digital ready. Plus, the Qed can be controlled with the included jog/shuttle control surface, keyboard shortcuts, the mouse or an optional touchscreen.
