This pre-main amplifier inherits the design philosophy of the PM-14SA and PM-17SA and is compatible with next-generation audio.
The DVD input supports a 6-channel input, and you can add a power amplifier to play SACD, DVD Audio, and other multi-channel sources.
A pre-power independent configuration is adopted to achieve high sound quality.
A newly developed current feedback type is used for all six channels in the preamplifier section to achieve low-noise, high-slew rate, high speed and dynamic range for next-generation audio.
The volume uses a motor-driven 6-series volume of die cast frame, which has less channel-to-channel deviation than conventional volumes and higher performance than electronic volumes.
The power amplifier section uses a current feedback type. By lowering the feedback impedance, the phase compensation is light and a high-speed amplifier is realized.
Power devices use L, A, P, and T transistors with excellent high-frequency characteristics, and separate left and right heat sinks to reduce vibration and thermal crosstalk.
The power supply section uses a super-ring-core toroidal transformer and a high-speed, low-loss, low-noise Schottky barrier rectifier.
The speaker terminal uses the latest model of the standard SA series pre-main amplifier made by WBT in Germany, and supports banana plug and Y lug.
The chassis is a double-layered chassis with an additional 1.6 mm thick steel bottom plate to reduce the impact of external vibration on sound quality and improve chassis strength.
Equipped with a CD & DVD direct input that is directly connected to the preamplifier section by a dedicated relay.
Equipped with a full Rec selector with Rec buffer.
The input / output terminals are gold-plated.
An inlet type AC cable is used.
