Apple xr signal is very good, xr is worth buying. The biggest highlight of the iPhone EXR may be the Apple A12 processor, which has run several times and is about 350,000, and the performance has reached the top level of the industry, coupled with the blessing of the IOS12 system, the daily fluency is quite excellent, noThere is no pressure on multitasking or playing games, perhaps because of the new machine, and there has been no deadlock in the use of this day, and the user experience is still excellent.
iphone XR cell phone signal is good, the phone quality is good. The advantages of the iphone XR Single-layer motherboard For the first time, a dual-layer motherboard design was introduced on the XR. The advantage of this design is that it can save space and enlarge the battery a little, and the disadvantage is that the heat dissipation ability is very poor. When running large games or software, it will cause the body to heat up, affecting battery life and performance. So the iphone XR is not like iPhone8 plays the game so well that way.
The Apple xr uses the Intel XMM7560 baseband, which is not as good as Qualcomm's baseband. The signal is not as good as Qualcomm's, and the stability is poor. Second, the iPhone XR doesn't have 3D Touch, which first appeared on the iPhone 6s, and its convenience, as anyone who knows it will understand, allows quick access to an app's secondary menu without opening it.
1, increase the transmission power of the microphone. Lowering the receiving silence level is to lower the receiving threshold, and at the same time, it is more susceptible to interference. Increase the antenna strong wave device, (general wireless microphone manufacturers have antenna systems, generally including antenna divider, antenna beat) is to send large received signals.
2, the use of all-pointing additional antenna, the antenna height or upside down hanging on the ceiling, and then directly connected to the receiver's antenna input socket with coaxial cable, can increase the receiving distance and signal reception quality. Because the higher the receiving antenna is set up above the ground, the farther the receiving distance, butBecause the elongation of the coaxial cable will cause the loss of signal transmission, it is necessary to select the cable with less loss according to the use of distance to compensate for the cable transmission loss.
3, is your wireless microphone V segment or U segment? You can put the receiver in the window position to try, if it doesn't work, you have to buy a new set. For a site like yours, you must buy a true diversity wireless microphone (single microphone dual antenna reception), you can avoid interference sources, in the case of obstacles can also receive a radius of hundreds of meters, about 2000 domestic, imported more than 5,000.
4. You can throw it off firstThe microphone amplifier stage directly uses MP3 or other sound sources to inject audio signals into the FM stage, and adjusts the turn of the oscillation coil to make the radio receive the music emitted by MP3 (the transmitting antenna is connected to the FM tube collector in series 10p capacitors). If the FM signal is still not received, check whether the operating current of the triode is between 1-2mA. If the current is normal, check whether the coil winding meets the requirements, and the signal can be received by adjusting the turn distance of the coil.
