  • X2 Digital Wireless Introduces New Microphone Systems

    By Guest |

    X2 Digital Wireless Systems, Inc. has announced today the expansion of the XDR Series Digital UHF wireless consisting of four new microphone systems:

    • DR952—omni lavalier microphone system shipping with MT830-X
    • XDR953—cardioid headworn microphone system shipping with ATM75-X
    • XDR954—cardioid lavalier microphone system shipping with MT831-X
    • XDR957—clip-on instrument microphone system shipping with Pro35-X


    XDR95-x systems are now shipping and include quality microphone elements designed by Audio Technica as standard equipment. Engineered and manufactured in the USA, the XDR95 is a multichannel 24-bit digital wireless system purpose-built for live performance in a multitude of environments. All systems are 2009 Compliant and feature X2's proprietary companderless TruDIGITAL™ format and Q-DiversityPLUS™ (anti-jamming) technology. The result: unrivaled digital audio quality, a 300' operating range and unprecedented reliability even in typically harsh RF conditions as well as the ability to operate freely throughout North and South America without frequency coordination issues or DTV/"white-space" concerns.

    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 instrument, line-level or microphone signals, and then transfers them in digital format on two separate RF carrier frequencies. 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 signal 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 to deliver total freedom from dropouts, multipath cancellation, RF interference and noise. With Q-DiversityPLUS, should an undesired RF signal suddenly appear on your channel, 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 900 MHz band, the system is free from DTV 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/C's common to analog wireless units. These compander I/C's typically add coloration and distortion, and can cause a noticeable modulation of the noise floor. The X2 system is notably free from all of these artifacts. The result is 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.
