NextGen Professional Phono Preamp Card

---

The NextGen Professional Phono Preamplifier card applies an information theoretic engineering and development approach to realize heretofore unmatched transparency and information retrieval from stereo and monophonic records, accepting and matching a very wide range of MM and MC phono cartridges directly, and that with the finest of decks, tonearms, phono cartridges and proper setup achieves a new standard in audiophile phono reproduction.

The NextGen Professional Phono Preamplifier cards are designed to be installed and used in the NextGen Audio Systems standalone 19" 3U rack-mountable chassis and associated external 115/230VAC 50/60 Hz power supply. This same chassis and accommodate BOTH NextGen A80RC Tape Repro and Professional Phono Cards per channel, if required.

Main Features:

• Entirely discrete, DC coupled Class A amplifier stages, essentially identical to those used on the NextGen A80RC plug-in and outboard-standalone tape repro and record cards (currently available for the ATR-102 and Nagra T-Audio), which redefine what was thought possible from analog magnetic tape, and has received many accolades for its incredible transparency and information retrieval;

• Fully transformerless audio design, exceptionally low noise/high SNR that eliminates the need for a separate MC step-up transformer or headamp (and their usual adverse effects) for nearly any cartridge - even low output MC types - for the widest dynamic range and the lowest possible distortion; suitable for MC cartridges with rated outputs as low as 0.2mV RMS at 5cm/s;

• Apart from RIAA equalization capacitors themselves (precision polypropylene for ultralow dielectric absorption), only one similar polypropylene capacitor for the DC Servo; NO AC coupling capacitors used, time-smear all but eliminated;

• Utmost attention has been paid to realizing the most accurate possible complete cutter-head to cartridge-output time domain response, that is, accounting as well for the master disk cutting process time domain characteristics itself to a degree (as far as we can tell) that has never been realized before;

• Separate switch-selectable Preamp/Equalizer stage AND Output stage gain settings to optimize BOTH signal to noise (SNR) ratio AND available dynamic range as needed depending on cartridge rated output levels and source impedance; maximum available gain is 37 dB (for Preamp/Equalizer) and 46 dB (for Output stage) for a total available gain of up to 83 dB at 500 Hz;

• Selectable cartridge loading, fine (+/- 2dB) front panel cartridge balance (gain) adjustment, switchable (15Hz) low-cut filter and "Flat" mode for use with constant velocity test records;

• Dual Outputs per channel: a Front Panel un-buffered Single-Ended (RCA) high-level phono output for highest possible audio quality where RFI/EMI environment and cable length circumstances permit, along with a Front-Panel un-buffered Balanced (XLR) output; high level outputs suitable for just about any modern preamplifier or integrated amplifier;

• A-Wtd SNR Ratio better than 83dB at 1mVRMS input with 3 ohm cartridge source impedance, and 1 Khz THD at that same level is less than 0.002% (-94 dB); A-Wtd SNR better than 69dB at 0.2mVRMS input with 3 ohm cartridge source impedance, and 1 Khz THD at that same level is less than 0.002%;

• RIAA conformance better than +/-0.6dB.
