NAB Show New Products
Bluepack: JK Audio combines Bluetooth Wireless Technology with professional audio electronics in a rugged new belt-pack design. Bluepack allows live man-on-the-street interviews through a cell phone equipped with Bluetooth wireless technology. Bluepack pairs to a cell phone like a Bluetooth wireless headset. A 3.5mm stereo line input jack allows recordings to be mixed into the broadcast. The 3.5mm stereo line output jack provides a full bandwidth microphone signal on the left channel and Bluetooth audio on the right channel. The stereo headphone output gives a mix of the XLR microphone input, 3.5mm input and Bluetooth audio. The 0.5W stereo headphone amplifier will cut through any crowd noise. Bluepack also pairs to Bluetooth equipped sound cards and music players in full bandwidth stereo A2DP mode.
Concert: Based on voice-over-Internet Protocol (VoIP) technology, Clear-Com Concert's audio features deliver crystal-clear sound and non-blocking communications over a standard Local Area Network or Internet between local and remote users. This eliminates the need for picking up a phone or connecting to a conference bridge. The interface facilitates ad-hoc communications and makes the user the conductor with easy drag-and-drop functionality. The Presence Awareness feature monitors participants' availability. The system, scalable to many hundreds of users, is designed with proprietary protocols and error recovery algorithms for mission-critical applications that include live broadcast productions. The system uses AES 128-bit encryption to provide security for protecting privacy of transmissions. Supporting a variety of codecs including wideband and ultra wideband, Clear-Com Concert provides realistic audio.
Model 525: The 525 is a frequency-agile, wideband AM-broadcast receiver that utilizes a highly linear phase-locked detector to provide accurate off-air measurements of AM carrier modulation. An important feature of this new monitor is the ability to resolve the amplitude-modulation component of the station's carrier during IBOC Hybrid Digital broadcast operation. Positive and negative carrier modulation is shown simultaneously on a high-resolution LCD display. This can be switched to provide a read-out of received signal strength and asynchronous noise as well, two parameters that can influence the modulation reading. Measurement response is pancake-flat to 10kHz, although a menu-controlled low-pass filter in the audio-monitor output provides a cutoff that can be programmed between 10kHz and 2kHz in 1kHz steps. This allows the user to preview the sonic compromises imposed by pre-transmission audio filtering and to simulate the response of consumer radios.
IFB 100: This 2.4GHz IFB transmitter is designed for use with the company's TRX900 series of wireless microphone systems. The IFB100 transmits a single RF carrier containing timecode, IFB audio, and remote control signals to any number of TRX900 wireless systems, giving users the ability to record a group of channels and play them back as a virtual multitrack recording. The unit directly accepts SMPTE timecode and balanced audio at line level. The IFB100's 125mW RF power output provides a range of up to 300 feet for transmission of IFB audio and up to 1,000 feet for timecode transmission and remote control signals. Its 2.4GHz frequency can be used license free in almost any country.
