Vida Vinyl Phono Disc Amplifier by Aurasound

Word of mouth and input from customers led me to yet another unique design that delivers world class musicality at a reasonable price. Once I heard it I had to make it available to my customers.

Key features:

 

  • Adopted LCR type RIAA device. Unlike conventional NF & CR type for RIAA curve, VIDA uses L (coil) to generate precise RIAA curve, resulting in much fulfilling midranges.
  • With use of the latest semiconductor devices and discrete amplifier circuit, it achieved a complete DC circuit design. As a result, capacitors in the signal path were completely eliminated.
  • High resolution in the low frequencies and reduced distortions, it enables you to enjoy vivid music hall atmospheres coupled with the players positioning on the stage.
  • A large-size MUTE switch together with other functions are aligned in the front panel for improved man-machine interface for user-friendly operation.
  • High S/N ratio was achieved with use of an external power supply unit, having extremely stable and super low-noise and high–speed circuits.
  • Compatible with MC and MM type cartridges. High/Low Impedance Selector switch on the front panel.

 


 

Useful functions for analog playback...

MC/MM Selector, MC Impedance Selector, Direct/Subsonic Filter, Stereo/Mono Selector, and demagnetizing function are featured. All the functions plus a large-size mute switch are placed on the front panel for user-friendly configuration. Each selector uses a sealed small-size signal relay for high reliability and stability. Also, highly durable rhodium plated RCA terminals are employed to ensure very low level signal paths are warranted without any loss.

 

     

Precision DC circuit with the latest semiconductor technology...

...eliminated all capacitors in the signal path. It enabled a completely flat frequency response without any coloration across the entire audible range. The active DC servo circuit permits absolutely stable outputs regardless of fluctuations in the inputs and operating temperature. Especially, resolution and distortion in low frequency are improved significantly, therefore, you will be able to even sense and feel the atmosphere of the music hall, performers and the staging. The power supply uses toroid transformer, Schottky barrier diode which allows ultra-low noise. Any leakage flux noises are completely eliminated with use of a separate power supply by employing high-speed semiconductor-based stable power supply circuit.

 

 

 

LCR Type RIAA device...

Unlike conventional NF and CR type, an ideal circuit design with constant impedance LCR-type RIAA circuit is used. As a result, across the entire frequency range, RIAA curve correction is achieved with constant condition. In the past, vacuum tubes were used with a large chassis, but VIDA managed in a compact size thanks to the latest semiconductor technologies. Each component is placed according to the signal flow in symmetrical and the shortest route. The equalizer circuit uses the renowned Swedish Lundahl filter-coil, which is widely used in the professional equipment, for turnover and roll-off independently.

Small signals recorded on the vinyl disc must be precisely restored to a flat response using (L) coil and CR network circuit, which go through the RIAA curve having attenuated lows and boosted highs. At the same time, it must be amplified by roughly 1,600 times (In case of MC cartridges). Since amplification is very large, any noises from the power supply and the circuits must be reduced to the possible minimum.
