Description
● We’ve taken another look at circuit constants and achieved a higher grade of reproducibility for SACD and other new-generation audio formats.
● Consists of a pure balance amplifier in which the XLR balance input does not have to pass through a transformer, an inversion amplifier, etc.
● Makes use of a simple two-stage amplification structure based on rigorously selected low-noise FET. The load resistance makes use of non-inductive coil resistance manufactured by Dale, thus realizing straightforward properties that take advantage of the features of vacuum tubes and outstanding sound quality with a high level of clarity.
● The output stage is designed to lower impedance by using a rigorously selected high voltage dual triode (6FQ7 type) in parallel connection, which has resulted in an improvement in dynamic range especially in the high frequency.
● The heater power source for the vacuum tube makes use of a power circuit of the DC ignition type using an electrolytic condenser and a high-speed Schottky barrier diode, bringing about further improvements in the SN ratio.
● Makes use of a large-capacity power transformer and capacitor.
● Equipped with one XLR (balance) input system and two RCA (imbalance) input systems, meaning that there is a total of three input systems.
● In the case of the RCA input, switching with the earth side ensures that there is almost no interference between devices.
● Use is made of a high sound quality quadruple volume unit which makes possible XLR input as well as all kinds of line level analog voice inputs.
● The RCA terminal “Input 1” is equipped with parallel output terminals and enables input throughout. Connection with other pre-amplifiers and recording decks, etc., is also possible.
