250mW Digital Hybrid Wireless Base Station Transmitter
Rio Rancho, NM – Lectrosonics is introducing the IFBT4, their latest IFB (Interruptible Fold Back) base-station transmitter. The new unit replaces their analog IFBT1 unit. The IFBT4 is a 250mW Digital Hybrid Wireless™ transmitter for IFB and other types of radio links. It is compatible with all Lectrosonics 100, 200, 400, and IFB receivers, along with receivers from two other manufacturers (contact Lectrosonics for details). In 400 mode, the IFBT4 and associated receivers operate without analog companding artifacts.
The IFBT4 is designed for use in broadcast, motion picture, theater and stage applications where extended operating range and high-quality audio are essential. The IFBT4 can be used as part of a stand-alone system or patched directly into popular intercom systems. DIP switches on the rear panel provide direct compatibility with RTS and Clear Com intercom systems while a preamp stage with a balanced input is also included to allow direct connection to dynamic microphones in addition to studio line level sources. A “tuning” mode is included so that the transmitting frequency can be selected without broadcasting.
The IFBT4 features a new backlit LCD with front-panel control for programming and operation. A selectable high-pass filter with settings at 35Hz and 50Hz allows for transmission of full audio bandwidth if required. The unit is housed in a rugged, machined aluminum, powder-coated shell for durability and an ultra-long service life. The IFBT4 is powered by 6 to 18 Volts DC via a locking connector and is supplied with a ¼-wave whip antenna that is detachable from the 50 Ohm BNC connector on the rear panel. Remote antennas can be used for applications where enhanced coverage is required.
Frequency response of the IFBT4 is 40Hz to 20kHz ±1dB in 200 and 400 modes. Availability: February 2007. MSRP: $1,085
