Degen DE1122 is a digital wide-band radio and MP3 combination product is an innovative field of radio.

I received a 1122 for some time, but also a comprehensive view over open, polished, machine basic understanding of the situation, so dare we talk about so-called up to the assessment of the machine. Oh, I believe we received a lot of people, I am simply following my own feelings on to the next bar.

Operation on this machine I feel really good, comprehensive inherited the advantages of 1102, as well as FM on the ATS function in use, making good use of the machine a lot, the battery box design of the machine is still a bit small, but compared to 1102 and strong so little, in his hand feels good, I prefer, it seems I scheduled a few less. I believe the future will be a lot of people want to buy

I think 1122 is ever sound Degen worst sound quality out of the machine!! That there is no bass, treble can not get out, is to use headphones to listen to is far better than 1102 and 1121, speaker is much worse to see inside the speaker know that lay inside the capacitor and the device is really the biggest disappointment, alas, MP3 part I do not say, we see, I think many people care about most is the here, huh, huh.

Sensitivity on FM is good, good, low noise, and 1103 similar to the basic income units, or good, while the accession of ATS use the machine better. Serious than 1102. AM I feel is not on good, and the local noise a bit high, as 1102 may be interference or a new design because, shortwave is not on the comprehensive ideal, but worthy of the price, compared to 1102 is still a little gap, it seems much interference .

I carefully polished and observed the 1122 circuit, which saw the original design of the circuit for the backlight, but less than a few resistors and LEDs, if they have the ability to add on it, and I polished the stability of the machine good, and never short of a whistle sound quality improvement is very good. we look pretty good picture:
