Description

From Manufacturer's website:
The MARGULES SF220 BLACK series combines the superior sound of vacuum tubes with innovative circuitry that pushes design boundaries with a fresh new aesthetic. The results are clearly apparent in its sound as a quick detailed dynamics, ultra-smooth transient response with an unprecedented reliability and beautiful contemporary design.The SF220's has very low output impedance, designed to drive optimally any amplifier regardless if is solid state or tubes.The Preamp’s wide and stable frequency response is maintained even with long cable runs, without softening or loss of detail which would normally be expected. The SF220 circuitry is designed to “strap” the input and output stage avoiding the use of negative feedback. The result is, load stability with precision, speed and dramatic transient response that gives a natural sound with reach detailed harmonics.Shunt Power supply and filament active damping.The SF220 BLACK EDITION includes a special SHUNT power supply. Shunt technology provides a dramatic improvement in Q damping, a key factor in overall performance, including smoother transient response and astonishing staging. Further improvements take place in quickness, macro and micro_dynamics, which make a life-like listening experi-ence.Our new Power Supply is virtually indestructible due to specially designed regulation technology that protects it from major tube failures. The filament supply is fully regulated and has an active damping control to minimize hum and microphonic effects of the tubes.The power supply is in a separate chamber within the chassis of the preamplifier to avoid noise induction.Remote controlBesides its IR remote control, the unit has RS232 connection to be controlled by any automation system or our web server.All the functions of the SF220 BLACK EDITION are discreet, including the ON and OFF function.The SF220's advanced design is complemented by the use of premium components. The PC board is silver-plated for maximum conductivity, Precision resistors, and premium audio grade capacitors.The SF220 BLACK is clean and effortless-sounding that it brings out the best in any power amplifier.New Aesthetics.The SF 220 BLACK has a new gloss black finishes, tubes blue led lighting, and engraved front panel and front push buttons control, featuring new Tzalam hardwood panel boardsFrequency response:5-400 khzTotal harmonic distortion:<0.014% maxMaximum output level:30 vSignal to noise ratio:4 OhmGain:6 dBRaise time:6 micro segundosFall time:6 micro segundosPower consumption (max):55 wWeight:14kgDimentions (height, width, depth):16 cm x 45cm x 36cm
