   Review:  Svetlana 2

 

 

                                          Svetlana 2            Korean

                                              Transformer Coupled

                Hi-End Tube Pre & Headphone Amplifier


               


             Profile


             Svetlana2 is tube amplifier which applies Headphone amp and Pre amp

             function. Headphone output is transformer method, so you can simple select

             either Low or High on the front side of panel.Also Pre Amplifier is put out

             low impedance. Also Pre Amplifier is put out low impedance.


             Especially signal input and out of headphone are isolated galvanically.
             So they shut off the headphone electrocute as electrostatic and also

             protect from inrush of current that occurs at power on and off.

             Svetlana2 Tube Headphone amplifier has adopted OPT and matching

             headphone impedance is seperated from low (25-62Ω) to high (300-600Ω)


             Pre Amplifier output is also transformer couple therefore, input and output

             signal are isolated. So they shut off hum inflow as 60Hz noise that is occurred

             as imbalance of signal ground. It can then provide silent signal without

             any noise to active speaker or power amplifier.


             Svetlana2 is well planned pure tube amplifier with tube and transformer.

             We selected high efficiency output transformer and optimized wide band

             frequency characteristics. It can be played the pure original sound with

             class-A triode of Zero Feedback design.

             Advantages of coupled Transformer

 

           1. Feel the sensation of pure energy and accurate image sound.

           2. Output is secured with low impedance, noise-free, silent background.

           3. Keep low frequency band even at low volume.

           4. The availability of wide frequency characteristics with highly efficient

               transformer.



              Vacuum Tube Sound Advantages

 

            We think one reason that why the tube amps have higher quality sound

            as compared to semiconductor amps is the difference between the

            sounds that is passed through hard solid and the sound that is passed

            through vacuum freely.The tube’s advantages are summarized in the

            following technical content.

            Vacuum Tube, Warm up, Life & Noise

 

           1. 10,000 hours secured by using military approved high reliable tubes

               (work 4 hours/day, 10 years guaranteed)

           2. Free from chronic white noise of semiconductor amplifier.

           3. Quick run time 15 seconds at switch on  2 minutes to warm up time.

           4. Prevent tubes hum noise by the block magnetic induction.

               with applied  toroidal power transformer.

           5. Experience free-noise tubes headphone amp to counter digital source,

               best noise cancelling guaranteed.
