スマホやタブレットのようにオーディオLSIの先にスピーカーやらBluetoothモジュールやらを繋いでいると、それら一つ一つがノイズ源になってしまいます。GODJはこれらの要因を極力排除する事で極めてノイズの少ない音を作り出すことに成功しました。GODJの電源を入れた状態でヘッドフォンをLINE OUTジャックに差し込んでみると、一般的なポータブル機によくある「サー」というホワイトノイズが一切聞こえない事がわかると思います。
Today, I'd like to talk about sound quality. It's hard to explain its sound quality just saying 'It's good', I will introduce a concrete figure, S/N ratio (ratio between sound and noise). In spite of a portable audio player, GODJ has achieved 100dB S/N ratio that is equal to high end home audio systems. You know why we could do this? We implemented direct connection between the audio LSI and audio jack, and drew the electric circuit as short as possible. There is a great advantage of this dedicated audio player in terms of design freedom.
If there are other modules such as a speaker or a Bluetooth chip connected to the audio LSI, they tend to become noise sources one by one. GODJ eliminated those factors in order to achieve extremely low noise level. Once you insert your headphone to LINE OUT jack while GODJ is turned on, you will notice that there are no white noise coming out from GODJ where as most of general audio players produce.
