1800 Series Application Diagram Audio-Technica U.S., Inc., 1221 Commerce Drive, Stow, Ohio 44224 Audio-Technica Limited, Old Lane, Leeds LS11 8AG England ©2010 Audio-Technica U.S., Inc. audio-technica.com 0001-0079-00 Camera Hop Description The dual channel 1800 Series wireless system is ideal for providing a wireless link between a mixer and a video camera, such as location sound situations where the camera operator and location sound audio engineer are typically linked by a breakaway cable or for the event videographer looking for a wireless link between the output of a sound mixer and their camera. This application consists of the ATW-1820(C/D) receiver mounted or located at the camera and two body-pack or plug-on transmitters located at the mixer output (for stereo feed). If the ATW-T1801 body-pack transmitter is used as the source transmitter, connect it to the mixer output using the XLRW cable. Set the gain trims so that the output of the mixer does not overmodulate the transmitter input. (The transmitter’s internal gain structure offers an 18 dB gain range.) If the mixer is sending a +4 line level signal, an in-line attenuator will be needed to match the mixer output to the transmitter input. If the ATW-T1802 plug-on transmitter is used, connect it to a mic level output on the mixer using a standard XLRM-XLRF microphone cable. An attenuator will be required if the mixer output is line level to properly match the mixer output to the mic level input on the transmitter. For best results maintain a clear line of sight between the transmitter and receiver. When using two transmitters, set their output power to “low” and keep them several inches apart to minimize RF interaction between them. Using the scan function of the receiver, set the system to operate on two compatable frequencies.
