The WRT-807A operates in conjunction with the WRR800A/801A/802A/805A, MB-806A UHF Synthesized Tuner for vocal concentration. The WRT-807A can be also used with existing Sony wireless microphone systems consisting of the WRT-810A/ 820A/822A/830A UHF Synthesized Transmitter and WRR810A/820A/840A/850A, MB-806A UHF Synthesized Tuner. The microphone/transmitter and tuners of the wireless microphone system are classified by frequency band. A 12 MHz frequency band (or two consecutive-numbered TV channels, such as 68 and 69 of the U68 model) is assigned to each microphone/transmitter and tuner model. In building up a UHF wireless microphone system, be sure to combine a microphone/transmitter and a tuner having the same TV channel number. For the selectable wireless channels and frequencies, see “Wireless Channel Lists” on page L-1. 4US Features Phase Locked Loop (PLL) synthesized system The WRT-807A features a refined phase locked loop (PLL) synthesizer circuit. POWER switch with holding function The POWER switch can be locked in the ON position to protect against accidental power cut-offs. Low-battery notification on tuner When the microphone battery is low, the microphone sends a warning to the WRR-800A/801A/802A/805A/850A, MB806A in the form of “Battery status information.” This information is sent to the WRR-800A/801A/802A/ 805A/850A, MB-806A about one hour before the battery goes dead to allow the battery to be safely replaced. When the WRR-800A/801A/802A/805A/850A, MB-806A receives this information, the LED and the LCD on tuner panel start to flash. Powered by readily available battery type The built-in, high-efficiency DC-DC converter provides about five hours of continuous and stable operation with just a single LR6 (size-AA) alkaline battery. LCD readout of various information The microphones LCD shows the current channel number, frequency, input attenuation setting, and residual battery power. The accumulated battery use time is also indicated (in oneminute increments) to allow precise monitoring of battery use. Automatic saving of channel and input attenuation settings All channel and input attenuation settings are automatically saved when the microphone is turned off (and are maintained even when the battery is removed), thus eliminating the need to make the same settings again the next time you use the microphone. Wide dynamic range and low noise The microphones compander (compressor/expander) system enables transmission over a wide dynamic range with minimum noise. Notes on operation • When operating two or more microphones, keep the microphones separated from each other by a distance of at least 30 cm (1 foot.). • Keep microphones at least 3 meters (10 feet) away from the receiving antenna. Highly reliable electronic attenuator Adjustable in a range of 0 dB to 21 dB in 3-dB steps, the built-in input level attenuator reduces signal distortion during the input of excessively strong audio signals. Tone signal-incorporated RF carrier signal The microphone transmits an RF carrier signal that incorporates a tone signal to enable any tuner with a tone squelch circuit to pick out only the target audio signal. 5US Parts Identification 1 Wind screen Protects against noise caused by wind. 2 Liquid-crystal display AF RF BATT Display example for U68 model A AF (audio input) indication Lights whenever an audio signal stronger than the reference level is received.
