Mounting the Microphone

On a Camera:

Slide the microphone onto the camera shoe.

Tighten the knurled ring to secure.

Tip:Inadditiontothevibrationisolationprovidedbytheshockmount,thelow-cutfiltercanbeusedtofurthereliminatehan-

dling noise and low frequency rumble.

Installing Batteries

This microphone requires one AA battery to operate (Alkaline, NiMH, or Lithium). To install:

Squeeze the door latches and pull the battery compartment open.

Insert the battery into the holder according to the polarity indicator and secure it into place.

Close the compartment by pushing the holder back in until it latches.

Low Battery LED: When the battery is running low, the LED turns red and the battery should be replaced as soon as possible.

See the battery life table in the user guide to determine remaining runtime after the LED turns red.

Audio Configuration

①Connect to the camera

or recording device

Plug the attached coiled cable into the camera's audio input. Alternatively, the microphone

can be plugged into a field recorder or other external device. It may be connected to both a

camera and a recorder by using a Y-splitter cable.

②Lower the camera's gain

(input volume) to the mini-

mum setting

Using the least amount of gain from the camera or recording device and more gain from the

VP83 will result in a better signal-to-noise ratio.

Note: Ifautomaticgaincontrolonthecamera(whenapplicable)introducesunwantedaudioartifacts,considerby-

passing the feature.

③Perform a sound check

and adjust the gain switch

ThedBgainswitchadjuststheleveloftheaudiosignalsenttothecamera'saudioinput.Be-

gin with the gain switch set to +20 dB. Monitor the camera's audio meter and adjust the

switchsothattheloudestsoundsdonotexceed−6dB.

+20 dB: Appropriatelevelformanycameraswhenrecordingtypicalsoundlev-

els (speech, for example) and for quiet sources.

0 dB: Use when capturing sounds that are slightly louder than typical speech

levels.

−10 dB: Use when the signal is too loud and distorts the camera's preamp, or in

loud environments, such as a concert or sporting event.

Note: Camera input sensitivity varies between manufacturers. Use this information for general reference.

④If necessary, increase

the camera's input gain

Theaudiosignalshouldpeakbetween−12and−6dBonthecamera'saudiometer.Follow

the camera manufacturer's instructions to fine tune the gain to reach the appropriate level.

Low-cut Filter

The low-cut filter reduces low frequency rumble caused by camera handling and other environmental factors by rolling off low

frequencies 170 Hz and below (12 dB per octave). To engage, slide the power switch to the low-cut filter ( ) position.

Monitoring the Audio Signal

To listen to the audio while recording, connect a pair of headphones to the camera's headphone output. Use the camera's

headphone volume control to adjust the monitoring level. Do not use the gain switch on the VP83 to adjust the monitoring level.

Why Gain Settings are Important

Propergainadjustmentisnecessarytoachievethebestsignal-to-noiseratio.Whenrecordingaudio,thecamera'spreampcir-

cuitry may introduce a small amount of noise that increases as the camera's preamp gain is raised, or when volume levels are

raised during post production.

How the VP83 improves performance: The VP83 microphone has very low noise characteristics, which means that using

moregainfromthemicrophoneandlessfromthecameraimprovesthesignal-to-noiseratioandresultsinacleaneraudiosig-

nal.

Troubleshooting

Issue Solution

Unit does not turn on Replace batteries and make sure that the batteries are installed correctly.

Sound is distorted

Check that the audio cable is completely inserted into the camera.

Camera input gain may be set too high, resulting in clipping. Try lowering the gain. If the

camera'sgainappearstobeadjustedproperly,trysettingthegainswitchto0or−10dB.

If listening through headphones, check the connection or try using a different pair.

No sound

Makesurethemicrophoneisonandthattheaudiocableisconnectedtothecorrectau-

dio input jack on the camera.

If the camera doesn't register a signal, try increasing the camera gain or setting the gain

switch to +20.
