PS-3250 Phono Equalizer Amp Kit Set

日本 ELEKIT推出 Phono Equalizer Amp [ PS-3250 ]

超值、細小之RIAA均衡器(唱頭放大器)套件

 

Tools required (需要工具): Diagonal Cutter (剪線鉗), Soldering Iron (烙鐵 / 焊接辣雞)

 

OUTLINE

  • This is an RIAA turntable preamplifier to convert a turntable’s phono-level output to an RIAA-equalized line-level signal, supporting both MM and MC cartridges by changing a jumper location on the PCB.
  • For OP-amp, a low-noise NJM2068DD is adopted.
  • In addition, for the electronic parts, ±1% tolerance metal oxide resistors and ±2% tolerance film capacitors are adopted to realize small RIAA deviation and low noise.
  • For the equalizer circuit, CR type is adopted and there is no concern for the deviation of equalizing characteristics even when OP-amp is exchanged.
  • A positive and negative voltage generating circuit is on-board for the power unit, and high quality sound and wide dynamic range are secured by supplying ±15V for OP-amp.
  • POP noise suppressor upon power ON/OFF is on-board.
  • In an equalizer amp, the noise level, especially the hum noise, depends largely on the IN/OUT wiring and the grounding location. (Therefore, for this kit, IN/OUT jack and grounding bracket to fix those parts to the PCB are included.)

產品概要

  • 這是RIAA標準唱盤放大器,用於將唱盤電平輸出轉換為RIAA電平信號,支援MM和MC唱頭。
  • 採用低噪聲NJM2068DD之運算放大器。
  • ±1%的金屬氧化物電阻及±2%的薄膜高級電子電容,以實現較小的RIAA偏差和低噪聲。
  • 具有優異瞬態特性CR型均衡電路,即使更換運算放大器也不必擔心均衡特性有偏差。
  • 電源電路板上帶有正負電壓,運放提供±15V的電壓,確保高質量的聲音和寬動態範圍。
  • 內置電源開/關時的『POP』噪聲抑制器。
  • 固定IN / OUT插孔與接地到PCB(底版)上,解決放大器之噪聲水平,尤其是『hum noise / 嗡嗡聲』。

【Specifications 規格及資料】

  • Corresponding cartridge : MM (Approx. 47kΩ), MC (Approx.100Ω or 30Ω)
  • Circuiting system : CR equalizer (RIAA), OP-amp dual amplification

  • Non-clip max. output (@1kHz) : 9V r.m.s.
