VIDA-MkII, new product announcement
Aurorasound Sep. 2021

VIDA-MkⅡVIDA was released in 2002,
after 10years now, its sound,
performance and design are
well evaluated, andrecognized as an
outstanding phono stage
amplifier in worldwide.
VIDA, LCR type equalization
system by semiconductor
circuit, this is the first
approach ever, and still keep
the distinguish position.
Now, we would like toannounce new version
VIDA-MkII.

Exterior design is not so much changed, because this design is already perfect and no room forimprovement. However internal circuit, PCB, specifications and sonic performance are refined.
Feature1. LCR filter type phono equalizer amplifier. L=inductor, C=capacitor, R=resistor.
2. To have ideal “L” of RIAA inductor, equivalent DC resistance factor is strictly selected to improve quality factor.
Use 4 pieces L. 2 for high range compensation and 2 for low range compensation. Aurorasound logo printed
special version made by Lundahl.

5.

Aurora AMP module2 rev4.0, discrete precision and high performance same with VIDA-Supreme.
Optimized signal flow and path by eliminating a wire harness by new print circuit board.
Robustness chassis design against external radio noise and magnetic leakage.
By these changes, L/R channel separation is improved +6dB, this is double improvement.
THD+N, Total Harmonic Distortion + Noise factor is improved from 0.028% to 0.012%. Double improved.
Stability and reliability are improved for longer term life.
Sonic perforce is enhanced. Fulfilling mid range, clear and tight bass, elegant high range with 3D stereo image.

Functions
1. Input section is changed from MC/MM to Phono-1/Phono-2
2. MC/MM selectable gain and load impedance for each inputs.
3. By this change, two MC inputs, two MM inputs or MC/MM inputs are selectable.
4. MUTE SW is changed to OMRON made, better touch and feel.
5. RCA jack, rhodium plated on solid brass. ( no changed)
6.

Customized options are available, as well as VIDA.
