Lectrosonics

The IFBT4 Frequency-Agile Compact IFB Transmitter (Block 470) from Lectosonics combines high-quality audio with an extended operating range to provide accurate and reliable sound transmission. In addition to serving as a standalone device, it can also be patched directly into many intercom systems. The transmitter uses Lectrosonics' Digital Hybrid Wireless System to transmit data to the receiver, combining the best of both analog and digital transmission. The transmitter is easy to use and program on the fly, thanks to the high-contrast LCD that is visible even in sunlight. Its machined aluminum construction ensures durability so the transmitter will last many years, even in the most demanding environments. Digital Hybrid Wireless TechnologyNone Lectrosonics Digital Hybrid Wireless systems overcome channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique that can be accomplished only in the digital domain, even though the inputs and outputs are analogNone Because it uses an analog FM link, Digital Hybrid Wireless enjoys all the benefits of conventional FM wireless systems, such as excellent range, efficient use of RF spectrum, and resistance to interference. However, unlike conventional FM systems, it does away with the analog compandor and its artifacts
