4USIntroductionThe WRT-807A is a UHF-synthesized wireless microphonefor use in a 800-MHz band UHF-synthesized wirelessmicrophone system.The WRT-807A operates in conjunction with the WRR-800A/801A/802A/805A, MB-806A UHF Synthesized Tunerfor vocal concentration.The WRT-807A can be also used with existing Sonywireless microphone systems consisting of the WRT-810A/820A/822A/830A UHF Synthesized Transmitter and WRR-810A/820A/840A/850A, MB-806A UHF SynthesizedTuner.The microphone/transmitter and tuners of the wirelessmicrophone system are classified by frequency band.A 12 MHz frequency band (or two consecutive-numberedTV channels, such as 68 and 69 of the U68 model) isassigned to each microphone/transmitter and tuner model.In building up a UHF wireless microphone system, be sureto combine a microphone/transmitter and a tuner having thesame TV channel number.For the selectable wireless channels and frequencies, see“Wireless Channel Lists” on page L-1.FeaturesPhase Locked Loop (PLL) synthesized systemThe WRT-807A features a refined phase locked loop (PLL)synthesizer circuit.POWER switch with holding functionThe POWER switch can be locked in the ON position toprotect against accidental power cut-offs.Low-battery notification on tunerWhen the microphone battery is low, the microphone sendsa warning to the WRR-800A/801A/802A/805A/850A, MB-806A 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 batterygoes dead to allow the battery to be safely replaced.When the WRR-800A/801A/802A/805A/850A, MB-806Areceives this information, the LED and the LCD on tunerpanel start to flash.Powered by readily available battery typeThe built-in, high-efficiency DC-DC converter providesabout five hours of continuous and stable operation with justa single LR6 (size-AA) alkaline battery.
5USLCD readout of various informationThe microphones LCD shows the current channel number,frequency, input attenuation setting, and residual batterypower.The accumulated battery use time is also indicated (in one-minute increments) to allow precise monitoring of batteryuse.Automatic saving of channel and input attenuationsettingsAll channel and input attenuation settings are automaticallysaved when the microphone is turned off (and aremaintained even when the battery is removed), thuseliminating the need to make the same settings again thenext time you use the microphone.Highly reliable electronic attenuatorAdjustable in a range of 0 dB to 21 dB in 3-dB steps, thebuilt-in input level attenuator reduces signal distortionduring the input of excessively strong audio signals.Tone signal-incorporated RF carrier signalThe microphone transmits an RF carrier signal thatincorporates a tone signal to enable any tuner with a tonesquelch circuit to pick out only the target audio signal.Wide dynamic range and low noiseThe microphones compander (compressor/expander) systemenables transmission over a wide dynamic range withminimum noise.Notes on operation• When operating two or more microphones, keep themicrophones separated from each other by a distance of atleast 30 cm (1 foot.).• Keep microphones at least 3 meters (10 feet) away fromthe receiving antenna.

If necessary, youcan determine which channels are usable by cycling thechannel selection through a number of channels on thetuner with the microphone set to OFF. Those channels forwhich the RF indicator on the tuner does not light areusable.• The microphone may not operate correctly if it is turnedon immediately after being turned off in Setting mode.Wait for a few seconds before turning the power on again.

14USTroubleshootingIf you have any problem using this unit, use the following checklist. Should any problem persist, consult your Sony dealer.Symptom Meaning/RemedyThe microphone does not turn on. • The + and – poles of the battery do not match those of the battery compartment. b Insert thebattery with the poles correctly matched.• The battery is exhausted. b Replace the battery with new one.• The battery terminals in the microphone are dirty. b Clean the + and – terminals with a cottonswab.The battery runs down quickly. • The battery is exhausted. b Replace the battery with new one.• A manganese battery is being used. b Use an alkaline battery. The battery life of a manganesebattery is less than half that of an alkaline battery.• The microphone is being used under cold conditions. b The battery runs down quickly under coldconditions.The microphone cannot be turnedoff. The HOLD switch is in locked position. b Change the HOLD switch to the unlocked position.The channel cannot be changed. An attempt was made to change the channel by pressing the SET button only. b Turn themicrophone off, then turn the microphone on again while holding down the SET button. Thenchange the channel with the + and – buttons.There is no sound. • The indication on the LCD is flashing. b The microphone is in channel setting mode. Turn thepower off, then on again.• The channel setting on the microphone is different from that on the tuner. b Use the same channelsetting for both the microphone and tuner.• The AF or RF indicator does not turn on. b Confirm that the microphone and tuner are both turnedon.
15USThe sound is weak. • The attenuation level setting is too high. b The output level is low. Press the – button in attenuationlevel setting mode to lower the attenuation level.• The volume on the amplifier, mixer or tuner is low. b Adjust the volume.There is distortion in the sound. The attenuation level setting is too low. b The input level is extremely high. Press the + button inattenuation level setting mode to raise the attenuation level.There is sound interruption ornoise. • The receiver's antenna is incorrectly connected. b Connect the antenna correctly according to theoperation manual of the tuner or antenna divider.• The antenna divider is turned off. b Turn the antenna divider on. It is possible for the tuner toreceive signals even when the antenna divider is turned off, but sound interruption or noise mayoccur.• The RF indicator lights even when the tuner is off. b Jammed transmissions are being received.Determine which channels are usable (i.e., channels for which the RF indicator on the tuner doesnot light) and set the tuner and microphone to the same usable channel.• Two or more microphones are set to the same channel. b Make sure no two microphones are set tothe same channel. Set each microphone to a different channel.Symptom Meaning/Remedy
