QODOSEN DX-286 Radio Introduction
1. The DX286 Adopts NXP highperformance car gauge chip TEF6686 to ensure excellent selectivity and ultrahigh sensitivity and provide you with a better receiving experience!
2. The FM radio frequency band supports 64to108MHz, supports RDS/RBDS broadcast data system, 5 frequency ranges are optional, 6 steps are optional, suitable for reception in different areas, there are 17 bandwidth options, and the selectivity is excellent.
3. Digital radio signaltonoise ratio ≥ 60dB, clear signal, low noise, builtin adjustable antenna attenuator to improve antioverload ability, built-in low-noise amplifier switching in long-wave/medium-wave/short-wave frequency band to improve receiving sensitivity.
4. All bands of the radio (FM and AM) support external antennas, and the use of external antennas can make the receiving effect of the
DX-286 better.
5. The longwave/mediumwave band supports the switching between the rod antenna and the builtin magnetic rod antenna, and the reception effect of the rod antenna or the external antenna is better in the environment with less outdoor interference.
6. Long wave/Medium Wave adopts DSP direct sampling and digital processing to improve the image interference caused by frequency conversion and harmonic interference caused by local oscillator of traditional radio. The adoption of new technology greatly improves the receiving performance.
18650 BATTERY POWERED/INDEPENDENT AMPLIFIER DESIGN
1. The DX286 portable radio uses 18650 batteries, which can be easily replaced. When the battery is dead, it can also be charged with a standard 5V USB charger (avoid using a fast charger to avoid damage).
2. The DX286 small radio adopts the independent dual power amplifier design of speaker and earphone, which are optimized and do not
affect each other, ensuring that the speaker output improves the sound quality of the earphone at the same time, with lower output noise
and smaller distortion.
External Antenna interface, support FM/long wave/medium wave/Short Wave Full Band
1. Improved signal reception quality: By connecting an external antenna, the radio's sensitivity to receiving radio waves is enhanced, thus
improving the quality of signal reception and allowing the radio to pick up more channels and clearer audio.
2. Expanded reception range: An external antenna can help broaden the radio's reception range, especially in areas with weak signals or
limited signal coverage, allowing for a wider range of reception.
3. Reduced interference: Indoor environments often contain various sources of interference, such as electrical devices and metal
structures, which can affect the radio's reception. Connecting an external antenna allows the antenna to be placed in a location with better signal reception, reducing the impact of such interference.
4. Convenient adjustment of antenna position: External antennas typically come with longer cables, allowing users to conveniently place
achieve the best signal reception. Users can optimize reception by adjusting the antenna's position and direction.
High Performance Automotive Chips
DX286 radio adopts TEF6686 car radio chip,this car radio DSP tuner offer outstanding performance levels with the broad range of
features and advanced algorithms(CEQ, EMS, lMS, and PACS,Noise Blanker..), software-defined radio signal processing,Especially in multipath improvement, adjacent frequency interference, weak signal processing, and noise elimination, it has significant advantages。
THERE IS ALWAYS A METHOD OF OPERATION THAT WORKS FOR YOU!
DX286 has 5 tuning modes, 100 editable pages, supports 1000 cross band storage stations, two storage sorting (ATS JUMP/ATS COVER), multiple search thresholds, multiple store/delete methods. Flexible operation.
Antenna switching
There are three antenna switching modes for long wave/medium wave. Select the antenna suitable for the environment to obtain the best reception effect.
1. In the case of indoor or electromagnetic environment interference, it is recommended to use the built-in magnetic rod antenna to receive (ANT INT).
2. If you are outdoors or in an electromagnetic environment with little interference, you can try to use a rod antenna to receive (ANT EXT). The rod antenna can bring you a better receiving experience.
3. In order to get better reception, you can use an external antenna in the "ANT EXT" mode.
ANTENNA ATTENUATOR
1. Enhance the receiving clarity: The attenuator controls the signal strength to prevent overload and distortion, and ensure that the broadcast is clearer and more stable.
2. Reduce interference: Minimize interference from strong electromagnetic sources (such as power lines or other electronic devices) and improve reception performance.
3. Improve selectivity: In a multi-frequency environment, it helps to filter out unwanted signals and enhance the receiver's attention to the required broadcast frequency, thereby achieving accurate and clear reception.
Built-In Low Noise Amplifier Switch
1. When reception is weak, you can enable the signal amplifier (AMP ON) to increase the strength of the signal, making it clearer.
2 If there is a signal overload when receiving a strong signal, you can turn off the signal amplifier (AMP OFF) to reduce overload.
3. When using an external passive antenna, it is recommended to turn on the antenna amplifier (AMP ON).
4. When using an external active antenna, it is recommended to turn off the antenna amplifier (AMP OFF).
FEATUERS OF FM BAND
The DX286 radio has an FM tuning range of 64 MHz to 108 MHz with 5 adjustable ranges to meet the range requirements of different countries. It enables precise tuning with 6 selectable steps and 17 bandwidth options, ensuring excellent selectivity in all environments. It also supports the RBDS/RDS data system for an enhanced broadcast experience,, and four different FM signal processing functions to improve signal quality.
MUSIC VOICE TONE
The DX-286 is equipped with a closed-cavity full-range speaker in its compact size, which excels in vocal and music details; and has a tone switching function, which allows you to adjust the details and layering of audio by selecting different gears (MUSIC/VOICE) to satisfy the listening experience of different users.
ONEKEY MUTE FUNCTION /SWTICH LCD ON/OFF
1.The OneKey mute quickly toggles mute on or off without adjusting volume gradually.
2.Turning off the display can reduce noise interference and improve weak signal reception for a better auditory experience.
