● we achieve a more high-quality reproduction of the new generation audio formats such as SACD review the circuit constants. ● transformer or inverting amplifier, etc. is not interposed to XLR balanced input, and then configures the pure balance amplifier. ● adopted a simple two-stage amplification configuration by low-noise FET that has been carefully selected, load resistance to achieve a gentle characteristics and highly transparent sound quality that takes advantage of the features of the vacuum tube is adopted DALE Co., non-inductive winding resistance have. ● The output stage is carefully selected high-voltage double-triode vacuum tube (6FQ7 type), and parallel connection to lower the impedance, was allowed to particular greatly improved the dynamic range of the high. ● Heater power vacuum tubes by adopting the power supply circuit of a DC ignition system with a large Chemicon (electrolytic capacitor) high speed Schottky barrier diode, SN ratio has been improved. ● Adopt power transformer and power capacitor of large capacity. ● Equipped 1 and lineage of XLR (balanced) inputs, the two systems of RCA (unbalanced) input, the input is now a total of three systems. ● By RCA input also ground side switched, interference between the equipment is now almost nil. ● Use a high-quality sound quadruple volume unit, other XLR input allows input of analog voice of all line level. ● "Input 1" of RCA terminal equipped with a parallel output terminal, is available through out the input. Can be connected with such other preamp and recording deck
