610LP為雙單聲道設計，全平衡電路佈局，設計上以參考級Moon 810LP為根基。

610LP內部包含一個超大電源供應，以鋼材作為隔離外殼，消除所有可能的干擾痕跡。其內是一個高品質環形變壓器，使用獨立電感直流電波(i²DCf)，和一個pi-type的濾波器以減少交流輸電的噪聲和多階段的電壓調節。共有四層電路板確保最短路徑，使用的Polypropylene薄膜電容器經過嚴格篩選，對稱的電路設計和使用精良的元件。

身為一個高度靈活性的唱頭前級擴大機，610LP提供可選擇的增益、阻抗負載、電容負載和均衡曲線(RIAA和IEC)。全部都可以在底部面板上找到DIP開關來調整。這些開關都在電路線上的最佳位置以維持最短路徑。這些調整讓610LP可以與任何唱頭一同工作。


610LP Technical Features

· An oversized power supply producing a DC signal with a noise floor of -140dB related to 1.0V,DC-100kHz

· Power supply voltage regulation includes i²DCf (Independent Inductive DC Filtering); There is one inductor dedicated to each integrated circuit type component (DAC, Op-Amp, etc.) in the audio circuit's signal path: 24 stages in all

· Selectable equalization curves for both the RIAA and the IEC standards

· Customized parts include metallized polypropylene film capacitors with very tight tolerances of 1%

· 4-Layer printed circuit boards with pure copper tracings for a much shorter signal path;
This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio

· Power supply featuring a "pi-type" filter comprised of 40,000uF of capacitance and dual choke inductance

· 12 Volt trigger input and output for remote operation

· Ultra rigid chassis construction to minimize the effects of external vibrations

· Accurate matching of the very finest quality electronic components in a symmetrical circuit design.

610LP可調整設定的相當完整，包括Capacitance, Resistance, Gain及IEC/RIAA等


隨機附上一個調整Jump的工具方便用家使用


功能非常單純，就是唱放，因此也只有一個Standby的開關


可看到610LP為全平衡設計，具有平衡in與out，另外有一組RCA in與out
一次只能選擇使用一個，不可同時使用(無設計切換)
