我可以敢說5000元以下!! 全無敵手!!
法國France超級入門黑膠唱盤,
ELIPSON ALPHA 100 RIAA , HK $4980.
Design, Engineered & Made in FRANCE
內置phono放大器, mm放大很多都有,但5千蚊樓下有mc就係不得了 !!
嘩?咁親民 ? 無錯!而且是 全機 100% 法國製造 !!
包括紙盒,膠袋? 真的很用心, 很應真嗎?
強勁製作包括 :
1 : 在法國特別訂製,獨一無二之唱臂.
2 : 而啤鈴軸心利用 ICB- Infinite Centering Bearing 型式進行,
做到背噪十分寜靜,不過5千元的唱盤內也屬於一流製作!
3 : 而最重要的唱臂支架軸芯方面, 它用上了Elipson 自我研究出的OTT
- Orbital Torsion Tonearm , 使到唱臂在工作時, 絕不產生噪音,十分可靠, 也十分穩定!
4 : 由開發到設計,Elipson 保持一向的忠旨,全部 100% 由他們的團隊,在法國
製造,開發, 決定不用其他廠商的配件,不OEM,ODM !!
5: 唱頭丹麥製造 Ortofon OM-10 Cartridge
Output voltage at 1000 Hz, 5cm/sec. 4mV
6:另外放大部分每聲道用上 T I LM49710 Op AMP
High-Performance, High-Fidelity Audio Operational Amplifier絕不苟且
Output voltage at 1000 Hz, 5cm/sec. 4mV

【精準傾斜感測,加速度計與運算放大器環環相扣】
前幾篇文章中,我們談到基於微機電 (MEMS) 的運動感測器,在工業、醫療等偵測傾斜、振動及定位用途,其實遠較遊戲、娛樂更具實質意義。今天的視頻分享,就來親眼瞧瞧參考電路的演示吧!影片中的電路設計,可在正、負 180° 內提供 1° 精準度。由於雙軸加速度計透過 x 軸或 y 軸加速產生的輸出電壓,會經由緩衝器對感測器輸出進行衰減和電位偏移,使其位準符合轉換所需;因此,這個加速度計必須具備較低的靜態電流和雜訊密度,以及出色的靈敏度。
之後,由四通道運算放大器 (Operational Amplifier,簡稱 OP / OPA / op-amp) 對這些訊號進行位準偏移、緩衝和放大,確保訊號處於適當位準,以驅動 12 位元雙通道 SAR-ADC 輸入。將訊號數位化之後,評估軟體可處理這些數據,進而計算電路板下緣與重力向量之間的角度。此外,用戶可將元件的每個方向軸置於一個 +1G 和 -1G 場域,以實現多點校準技術、移除兩個軸之間的任何直流偏移誤差或靈敏度失配。

Shopping for a British distortion pedal? Try NUX Brownie!
Classical British rock tones of 1970’s are packed into this little box.
How it works?
By using a hybrid of circuits, we create preamp and power tube distortion characteristics. You’ll be amazed to hear the warm and organic tone reproduced by it.
A special designed BJT input stage makes this distortion pedal breakup in a way when the preamp tube starts to distort. Also, Brownie has an asymmetrical clipping circuit with which you can simulate some of the characteristics of a tube amplifier. It can also keep the bottom tight by processing bass frequencies from getting muddy when they are distorted.
NUX Brownie uses a low-pass tone control filter to simulate the Variac effect (lower the voltage going into the amplifier) for rounding of your tone. The range of tone is controlled yet very useful in dialing the high end response.
The power clipping circuit is crafted from modern low noise op-amp and two red LED. It can create symmetrical clipping that distort both half of the signal and keep the sound smooth. True bypass circuits with a high quality TPDP mechanical foot switch makes the bypass signal clarity.
