IP codec

Tieline Technology

Booth N8123

Bridge-IT: Bridge-IT allows the user to tailor the codec to suit individual requirements. Available in encode- only, decode-only versions or both, Bridge-IT has an SD card slot for failover playback of prerecorded audio, and the unit's menus can be fully programmed using comprehensive front-panel hardware that includes a keypad and LCD display, or by using a Web interface. It is designed for desktop use, or two units can be installed side-by-side in a purpose-built 1RU mounting bracket. Bridge-IT comes with a range of high performance broadcast algorithms plus optional AAC LC and AAC HE. Standard algorithms include 16-bit 22kHz linear audio at less than 12ms encode delay for uncompromised audio, G.711 G.722, MPEG Layer 2 and Tieline Music. The Tieline Music Plus algorithm also provides 22kHz mono, dual mono and stereo with 20ms encode delay at under 100kb/s. Bridge-IT has all the broadcast input connectors you would expect on a fully-featured codec. Simultaneous analog and digital AES/EBU audio outputs are provided on XLR connectors and it includes a 1/4" stereo headphone output.

Portable recorder

Samson Technologies

Booth SL10125

Zoom H4n: The H4n's onboard X/Y stereo condenser mics are arranged with the right and left mics on the same axis. This design ensures that the mics are always equidistant from the sound source for proper localization without phase shift. Each mic capsule can be rotated from 90 degrees (standard) to 120 degrees (wide-angle) stereo. The H4n allows four-channel simultaneous recording by using its onboard mics with either external mics or direct inputs. Choose up to 24-bit/96kHz linear PCM WAV files a variety of MP3 formats from 320kb/s down to 48kb/s.

Single-phase rack-mount UPS

Staco Energy Products

Booth N2814

Unistar C: Standard functions on these 1, 2 and 3kVA rack-mount models includes hot-swappable batteries, an internal battery charger, emergency shut-down and programmable receptacles. This double-conversion UPS protects from outages and irregularities in incoming line voltages from 60 to 144Vac or 120 to 288Vac at 45-65Hz. A steady sine wave protects downstream equipment even without going to battery mode. Each Unistar C features PWM sine-wave topology. The high crest factor of the inverter handles all high in-rush current loads without the need to upgrade the power rating. DC-start function ensures that the UPS will start even during a power outage. An LCD display provides real-time indication of all major system parameters and status, including load level, battery remaining and fault signals. Digital signal processing (DSP) provides the UPS with powerful communication capability, which enhances the flexibility for easy remote control and monitoring.
