Sound Level

Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S. Occupational Safety and Health Administration (OSHA) has specified permissible exposures to certain noise levels. According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in hearing loss. When using equipment capable of generating high SPL, use hearing protection while such equipment is under operation.

Hours per day	SPL (dB) Example
8	90	Small gig
6	92	Train train
4	95	Subway level
3	97	High level
2 100 Classical music concert
1.5	102	Riveting machine factory
1	105	Machine
0.50	110	Airport
0.25 or less 115 Rock concert

Setup

Items not listed under Introduction > Box Contents are sold separately.

Example 1 - Mono Operation

To send a mono signal from a single transmitter to the receiver:

1. Connect your microphone to the mic input on the transmitter, and connect the receiver's audio output to your camera's external mic input. Keep the volume controls on the camera at its minimum settings.
2. If necessary, adjust the RF dB level on the transmitter to get a strong signal for better operating range and noise resistance.
3. Turn on your camera, adjust the RX output level on the receiver and the input level of the camera's external mic input to hear the audio signal (or view the level on the input level of the camera).
4. In the audio recording settings on your camera, make sure it is set to Manual rather than Auto. Check the input level meter, and adjust the level so that the loudest sounds peak around -12 dB. Make sure the sound does not exceed 0 dB, which will cause the signal to distort.

Example 2 - Stereo Operation

To send a stereo signal from 2 transmitters to the receiver:

1. Connect your microphones to the mic inputs on the transmitters, and connect the receiver's audio output to your camera's external mic input. Keep the volume controls on the camera at its minimum settings.
2. If necessary, adjust the RF dB level on the transmitter to get a strong signal for better operating range and noise resistance.
3. Turn on your camera, adjust the RX output level on the receiver, and the input level of the camera's external mic input to hear the audio signal (or view the level on the input level of the camera).
4. In the audio recording settings on your camera, make sure it is set to Manual rather than Auto. Check the input level meter, and adjust the level so that the loudest sounds peak around -12 dB. Make sure the sound does not exceed 0 dB, which will cause the signal to distort.
5. Set the receiver's Output menu to Stereo and adjust the output level to get a strong signal without clipping.
