■This is an RIAA turntable preamplifier to convert a turntableʼs 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 OPamp, 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 OPamp is exchanged.
■A positve 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 OPamp.
■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 wirintg and the grounding location.
Therefore, for this kit, IN/OUT jack and grounding bracket to fix those par ts to the PCB are included.
