QY4AVT9003A900 MHz Audio/Video Transmitter

Long Range Wireless Applications USER’S MANUAL 900 MHz Audio / Video Transmitter Model No. AVT900-3A Product Description Model AVT900-3A from Applied Wireless, Inc. is a high quality transmitter designed to broadcast standard NTSC or PAL video signals, along with line-level audio signals, to an appropriate receiver (such as Applied Wireless Inc.’s model AVR900-3). Conforming to FCC Part 15 requirements for unlicensed use, Model AVT900-3A will transmit over distances up to 750 feet.* The range may be increased substantially through the use of a directional antenna (such as a flat panel or yagi) at the receiver. The AVT900-3A transmitter provides three user-selectable channels of operation to enable simultaneous operation of multiple transmitters in a common area. The transmitter incorporates precise FM modulation and sophisticated filters to ensure stable, interference-free high quality color or B/W video plus audio reception. The AVT900-3A transmitter is housed in a small yet rugged aluminum extrusion enclosure (dimensions: 3.25”W x 2.5”L). An AC power converter (12VDC) is supplied, along with RCA phono-type video and audio cables, as well as a combination multi- conductor power/audio/video cable assembly, for connection to video and audio sources. The AVT900-3A transmitter is well-suited for many diverse applications, including distribution of AV entertainment content throughout a building, commercial and industrial surveillance, monitoring, security, access control, etc. Using the AVT900-3A in Non-Stationary Applications If the AVT900-3A is to be used in an application in which it will be moving while broadcasting (such as with a hand-held video camera, for example), it is strongly suggested that the Applied Wireless Diversity Receiver (model DAV900-3) be utilized. This advanced multi-antenna receiver will minimize the effects of multipath interference to provide more stable video images and audio reproduction. The improvement in performance is especially noticeable when the distance between the transmitter and receiver is extended and/or obstructions exist between them. * Unobstructed, straight line-of-sight range, when used with the transmitter’s standard quarter-wave antenna (included).

The physical location and orientation of the unit itself will have a significant influence on reception quality at the receiver, particularly at longest ranges. The unit, and its standard antenna, should be positioned vertically (pointing either up or down). If necessary, use double-sided foam tape or hook & loop fasteners (not supplied) to secure the unit to a vertical surface. Also, keep in mind that the RF signal from the transmitter will travel through most non-metallic building materials (wood, stucco, brick, etc.), however maximum stated reception range is based on unobstructed line of sight conditions. Selecting the Channel of Operation Referring to Figure 1, use a small flat-blade screwdriver to select the channel (frequency) on which the transmitter will broadcast, by aligning the triangle-shaped pointer (not the screwdriver slot) to the number of the desired channel. Be sure to set the receiver to the matching channel. Channels are as follows: Channel 1: 907 MHz Channel 2: 915 MHz Channel 3: 923 MHz Any other setting of the channel selector (0, 4, 5, 6, 7, 8, 9) defaults to Channel 1. If two AVT900-3A transmitters are to be used simultaneously in a common area (so as to broadcast two different audio & video sources), set one unit to Channel 1 and the other unit to Channel 3. It is not advisable to attempt to use three units simultaneously. Connecting Audio and Video to the AVT900-3A Following the guidelines below, connect line level audio and video sources (outputs from a DVD player, for example) to the corresponding line-level input jacks on the transmitter’s rear panel (refer to Figure 2). Audio – If a microphone is to be used as the audio source, an external microphone preamp (not supplied) must be used to raise the microphone’s output signal to the required line level. Video – The AVT900-3A’s video input presents a terminated 75-ohm load to the output of the video source device. Accordingly, no other device(s) besides the AVT900-3A should be connected to the video source. If any additional device(s) must be driven by the source device, a video distribution amplifier (not supplied) must be used. Connecting Power to the AVT900-3A The AVT900-3A requires an external power source of between 7.5 and 18 volts DC. A plug-in power converter (12VDC) is supplied with the AVT900-3A. If preferred, a battery (not supplied) may be used instead of the power converter. A 9volt alkaline battery will operate the transmitter continuously for several hours. Figure 1 - Front Panel Figure 2 – Rear Panel CAUTION: Do NOT apply power to the AVT900-3A unless the supplied antenna is attached to its mating jack on the front panel. Powering the transmitter without an antenna may result in failure of the transmitter’s RF output device and void the warranty. To use the supplied power converter, insert its 2.1mm plug into the DC IN jack on the transmitter’s rear panel (refer to Figure 2). Plug the converter into a live 120VAC outlet. The transmitter’s red Power indicator LED (on the front panel, refer to Figure 1) should illuminate. To connect a battery, refer to Figure 3 and Table 2. Using the Combi…
