X2 Digital Wireless Systems, Inc. has announced that the XDR95 is now shipping and available through authorized dealers. Engineered and manufactured in the USA, the XDR95 is a multichannel 24-bit digital wireless system. The system features X2’s proprietary companderless TruDigital™ format and new Q-DiversityPlus™ (anti-jamming) technology for the sound and feel of a direct wire connection with a 300-foot operating range and unprecedented reliability even in harsh conditions including RF interference.
The XDR95 draws its wired-sound characteristics from X2’s patent-pending TruDigital technology. A 24-bit A/D converter at the XDT4 bodypack transmitter captures the full dynamic range of incoming signals and transfers them in digital format on two separate RF carrier frequencies (odd samples on one, even samples on the other). The XDR4 Receiver decodes the signals back into analog audio via a 24-bit D/A converter.
Two permanently mounted internal UHF antennas and two BNC chassis mounted external antennas supply RF signals to four separate receiver sections within the single rack space chassis of the receiver creating what X2 calls Q-DiversityPlus—four completely separate receiver sections working simultaneously to deliver total freedom from dropouts, multipath cancellation, RF interference, and noise. With Q-DiversityPlus, should an undesired RF signal suddenly appear, the performance will not be adversely affected. This is essential when considering today’s wide presence of cell phones/blackberrys, wireless networks, and other unforeseen or unknown sources of RF energy.
What’s more, by operating in the Frequency-Clear™ 902 - 928 MHz band, the system is free from DTV and related “white space” concerns and FCC licensing concerns. The result is a reliable performance in a multitude of environments now and in the future.
The entire process takes place without the use of compression/expander (compander) noise reduction I/Cs common to analog wireless units. These compander I/Cs typically add coloration and distortion, and cause a noticeable modulation of the noise floor. The X2 system is notably free from all of these artifacts. The result is a signal to noise ratio greater than 118 dB and a frequency response from 10 Hz to 20 kHz, +/- .5 dB (half a dB or less), while dynamic range is >118 dB, with a THD of <.03%.
Equipped with a multisegment LED display providing instant feedback to all integral system functions, the XDR95 components are free from complicated setup procedures and multipage menus. The XDR4 receiver shows operating channel, diversity status, RF signal, audio level (16 segment), and remaining battery life in the transmitter (16 segment) in 20-minute increments. The XDT4 bodypack transmitter shows operating channel, remaining battery life (in five one-hour increments), and audio level when signal is present. Both components offer five user-selectable and fully compatible operating channels.
The system can additionally be used with other manufacturers headworn, lavalier, or instrument microphones wired for 1/8” TRS connector when using the XDT4 bodypack transmitter. XDR95 Components can alternately operate in a backward compatible mode to accommodate previous X2 systems and components.
