Diamond Cut is proud to offer our newly redesigned DCP-47K-F Flat Response Magnetic Phono Cartridge Pre-amp.

The New Way Of thinking about vinyl restoration starts with a flat response phono pre-amp. The DCP-47K-F offers incredible specs and delivers a perfectly flat signal to your computer…ideal for enhancing with DCart and transferring to CD. For the first time you can actually get pretty darn close to what the producer heard when your favorite recordings were played in the studio. This isn’t just theoretical.

The Diamond Cut Production’s DCP-47k-F flat response magnetic phono cartridge preamplifier is intended for use with Diamond Cut Production’s audio restoration software which contains a Virtual Phono Preamplifier (VPP).  Most phono preamplifiers include an RIAA curve within their design circuitry, which produces some distortion and does not perfectly re-create the RIAA curve.  The DCP-47K-F produces a ruler-straight frequency response across the entire audio spectrum. By transferring your record(s) to your computer’s line input via the DCP-47K-F and then processing them through the Diamond Cut Productions Virtual Phono Preamplifier, you will be able to apply any of a variety of choices of EQ curves (including the RIAA curve) to the transferred record file.  The Virtual Phono Preamplifier software algorithm then applies an EQ curve with a high degree of mathematical precision and lower inter-modulation distortion added to the signal. Because the phonograph signal is being transferred “flat” you can also perform fractional speed mastering or high speed dubbing without distorting the record’s EQ curve (sometimes called EQ Shift)*.  These capabilities are beyond that of analog based phonographic EQ systems.

Note1: Most laptop computers do not have line-level inputs.  You will either need a tower computer or an external sound card if you are to use a laptop
