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』。
