Lectrosonics targets congested RF environments
Published: PRODUCTS
The Venue 2 Digital Hybrid Wireless modular receiver has been designed by Lectrosonics to address the challenges of congested RF environments. The unit calls on the US manufacturer’sHowever, the standout H IQ dynamic tracking filters as the centrepiece of its technology. According to Lectrosonics, this offers the key elements required in congested RF environments such as ‘rejection of out-of-band RF energy’ and ‘very tight channel spacing’ as well as accommodating ‘a wide range of transmitter RF power levels’.
The receiver tunes across a 220MHz range and houses up to six VRT2 receiver modules. Each module reportedly supports up to 3,072 tunable frequencies across a 75MHz range, matching the tuning ranges of the SSM, LT and LMb transmitters. The receiver modules can be operated independently, each with switched diversity reception for a total of six audio channels, or operated in pairs with one audio channel per module pair. Combinations can reportedly be mixed and matched within one frame.
The VRT2 modules are offered in four different frequency ranges for worldwide use: A1, covering blocks 470, 19 and 20 (470.100 - 537.575MHz), B1, covering blocks 21, 22 and 23, (537.600 - 614.375MHz), C1, covering blocks 24, 25 and 26 (614.400 - 691.175MHz) and D1, covering blocks 27, 28 and 29 (691.200 - 767.975MHz).
Completing the solution is a built-in antenna multicoupler with loop-through output. The multicoupler is a dual one-in, seven-out splitter with six outputs for the receiver modules and an additional output as a unity gain loop-through for another Venue receiver. This allows multiple Venue receivers to operate from a single pair of antennas. Phantom power for remote antenna amplifiers is available from the multicoupler antenna inputs and is selectable in the menu.
Described by Lectrosonics as the perfect companion for Venue 2, the HHa is the latest addition to its range of handheld transmitters. The HHa features a tuning range of 75MHz, selectable RF power of 50 or 100mW, IR sync and a USB port for firmware updates in the field. It offers a frequency response of 40Hz to 20kHz ±1dB, 105dB (A) signal to noise. The patented Digital Hybrid Wireless process delivers compandor-free audio and uses an analogue FM carrier to transmit a specially encoded signal.
The HHa’s standard capsule mount reportedly accepts a wide range of industry-standard dynamic, electret and condenser microphone elements. The unit also features a programmable external button which can be set as mute, cough, power, talkback, or bypassed altogether.
