Anaheim, CA (January 14, 2011)–Lectrosonics has debuted the Quadra digital wireless monitor system at Winter NAMM 2011.
The new Quadra system, consisting of the M4R belt-pack diversity receiver and M4T half-rack transmitter, features digital RF modulation, two or four channels of 24-bit/48 kHz digital audio, analog or digital inputs, and a unique mixing interface for users. The Quadra system operates in the license-free ISM band between 902-928 MHz and reportedly has a throughput latency of 1 ms for analog inputs and <0.5 ms for digital inputs.
The M4R diversity belt-pack receiver features a high-resolution, backlit LCD and membrane switches. A four-channel mixer allows the performer to tailor the mix in real time, based on what is sent to the transmitter from the monitor console. Several channel setups and knob configurations are available, giving the user a variety of choices as to how the system operates. The M4R is said to run for 6 hours on three alkaline AA batteries.
The M4T half-rack transmitter features transmission power of 200 mW for extended operating range. Locking XLR connectors allow up to four channels of either analog or digital (AES/EBU) audio sources to be applied to the transmitter. Included hardware allows rack-mounting two M4T units together in a 1RU configuration. A USB jack allows for future firmware updates in the field. The M4T operates on AC mains power, avoiding the use of a wall-wart.
“We have been asked repeatedly for many years to make an IEM system,” states Karl Winkler, director of business development at Lectrosonics. “We didn’t want to make a ‘me-too’ product, though. Instead, we based the Quadra system on our own D4 digital wireless platform, which has already been proven for film and TV production.” Winkler continues: “With ultra-low latency, digital audio and four channels, I think we have a unique solution for the touring market. Furthermore, by virtue of its use of the license-free ISM band between 902-928 MHz, Quadra can be added to most existing wireless microphone installations without ‘stepping on’ what is already in place.”
