 HA-3000 Vacuum Tube Prepreamplifier [Head Amp]

PRINCIPAL FEATURES

⊙ Innovative Fixed Bias Circuit

   In the HA-3000, nuvistor tube 7895 or equivalents,
   the smallest vacuum tube performs its perfect role,

  as for amplifying device, enhancing the tiniest signal in audio,
   the output voltage of MC cartridges to fit to MM input of phono stages.
   ALLNIC applies its innovative fixed bias circuit to get quieter
   and more stable operation of the tubes, furthermore
   this circuit eliminates automatically the subsonics 
   so harmful to phono stages, due to the very characteristics 
   of R.I.A.A Curve, which mercilessly amplifies
   the lower frequencies the louder and breaks the tonal balance. 
   Again this fixed bias circuit sustains a negative 
   DC voltage to the grid of tube and to the input coupling capacitor 
   and blocks fundamentally "the zero crossover distortion" of capacitor,
   so common phenomenon, so easily neglected in ordinary prepreamplifiers.

   The result of no "Zero crossover distortion", the clearer and the more
   vivid reproduction of the music.


⊙ Very High S/N Ratio

   The above mentioned characteristics of R.I.A.A curve demand hum-free clean 
   prepreamplifier, which finally induced to clean power supply circuit.
   Even one micro volt(1/1,000,000 of one volt) of hum noise(120Hz hum)in the 
   output signal of a prepreamplifier will result 63mV to the final loud speakers.
   No one could accept it.
   ALLNIC has strong technology of automatic voltage regulation circuitry by pure 
   vacuum tubes. This voltage regulation circuit rejects any hum noise to the naught
   practically.


⊙ Extremely Wide Frequency Range

   Though HA-3000 has single gain stage. it has the capacity
    to extend from 15Hz up to 30Khz and could reveal the richest
    musical information of vinyl grooves, never heard .

⊙ Ultra Flexibility

   The capability of following up so unpredictable musical signals with ease
   could be graded by the responsibility to the square wave of high frequencies,
   especially at 10Khz, rarely at 20Khz, this ability is strongly believed
   to be the core of the musicality in audio equipments.
   ALLNIC shows the response shape at 20Khz beautifully.


⊙ Micro-Phonic Free Tube Damping Know-how

   ALLNIC`s Absorb-Gel® tube damping know-how culminates in HA-3000,
   every extreme technology applied.

⊙ Variable Input Load Impedances.

   HA-3000 has four input load impedances 50, 100, 200,
   and 500 ohms selectable from front panel according
   to the output impedances of your MC cartridges.
   Furthermore these loads are pure resists, not compound
   one of step-up transformers, so it gives pure and clean sound.
