Product Description
2.4G wireless audio transmitter uses advanced microwave wireless transmission technology, high-fidelity wireless transmission of video and audio signals, audio / video with broadband characteristics, signal to noise ratio is high, can transmit signals including DVD, VCD, CD, TV , videos, etc., the aircraft design has eight adjustable frequency, you can choose the best one based on the actual channel.
First, the machine has 8 channels to choose from, Modulation: FM / FSK, wireless audio and video transmission frequency range: CH 1 = 2414MHZ CH 2 = 2432MHZ CH 3 = 2450MHZ CH 4 = 2468MHZ frequency, fully guarantee the sound and image clear reception, using 2.4GHZ international common frequency, the use of RF CMOS highly integrated IC, highly integrated power amplifier (PA) and voltage-controlled oscillator (VCO) and two-channel audio and video in one of the modulation, the latter stage power amplifier using the German Siemens company GaAs chip for power amplifier, excellent high-power transmitter, remote, image stabilization, audio frequency response degree appealing is the biggest features in the barrier-free environment using the machine, wireless transmitting distance is greater than 2 km, to receive clear and stable images.
Second, the use of excellent FM mode, with excellent audio / video reception quality
– Audio / video with broadband characteristics, signal to noise ratio is high. As a signal source to DVD, video and signal reception directly connected to TV viewing results directly comparable. Send CD audio, stereo effect is excellent, superior sound quality
– Wide range of applications for expansion
Third, the technical parameters of the video input (one way) two-channel audio inputs (2 channels) (6.0MHZ NTSC 6.5MHZ PAL) Transmit Power: 32.5dBM Maximum current consumption: 1600mA Input voltage: 12V Receiver Frequency: CH 1 = 2414MHZ CH 2 = 2432MHZ CH 3 = 2450MHZ CH4 = 2468MHZ receiver sensitivity:-90dBm receiver maximum current consumption: 160mA input voltage: 12V video Output (1 channel) stereo sound output (2-way) (6.0MHZ NTSC 6.5MHZ PAL) 2.4 GHZ wireless video transmitter receiver working temperature: -10-120 degrees, RF radiation Distance: Accessible greater than 2000m
Can be used in hospitals, schools, shopping malls, companies, warehouses, residential, home and other places
– Compact, size: 102 * 60 * 30mm
– Good performance and low cost, easy to install
Installation Method:
1 Connect the power adapter to the transmitter (2A), plug in the power, the red light, proved successful powered transmitter;
2 would be another power adapter connected to the receiver input (1A), plug in the power, the red light, proved successful powered receiver;
3, with audio / video cable to the transmitter and the signal source (such as DVD, camera) phase, receiver and display phase, transmitter, receiver, channel s
Special Note: The frequency of the transmitter must be connectedSame frequency receiver, (where the transmitter and receiver must be the same red DIP switch) or no signal is received!
Troubleshooting
If you use the 2.4G audio / video wireless transmitter when there are still problems, please carefully read the user instructions. Here are solutions to some common problems.
5.1 No picture or sound
a. Check that the power adapter is connected correctly
b. power key is adjusted to the correct position
c. Check the connection cable is intact, the connection is correct
5.2 the interference image and sound
a. slowly move the transmitter and receiver to the best AV receiver position
b. shorten the distance between transmitter and receiver
c. checking whether the receiver near the radio frequency interference, such as microwave ovens.
d. If the receiver near radio frequency interference, change channels in order to achieve the best results
e. Check whether the transmitter and receiver to the same channel
5.3 Can not remote video source
a. Check the remote control batteries are charged
b. determine whether the alignment of the infrared remote control receiver window
c. determining transmitter and the receiver, the distance between the receiver and transmitter in the valid range.
