        Product details

        PURIFI 1ET400A | Eigentakt | Amplifier Module

         

        This high-performance amplifier module is based on the Eigentakt technology from PURIFI. The 1ET400A is one of the most high-end options from our amplifier module category. Eigentakt is the implementation of PURIFI's continuing research into nonlinear control theory that produced the first mathematically exact largesignal model of self-oscillating amplifier controllers. This breakthrough allows complete optimization of the feedback circuit and improves performance by at least an order of magnitude over existing implementations. The Eigentakt technology allows for extreme low THD at any frequency and power level. The negligible IMD (intermodulation distortion) creates a highly resolved and stable stereo image. Thanks to the very low output noise, this exceptional performance is preserved even at low listening levels.

         

        The 1ET400A also features a comprehensive protection system that makes it robust and easy to integrate. 

         

        Features

        • High loop gain (>75dB) in the entire audio band
        • Negligible Intermodulation Distortion (IMD)
        • THD remains extremely low at any frequency and any power level
        • Negligible output noise
        • High power supply rejection ratio (PSRR)
        • Controlled, second-order low-pass response

         

        What’s In The Box?

        • 1ET400A amplifier module 

         

        The 1ET400A module requires attention on the power supply and signal input connections. We recommend to use a dedicated front-end module that provides a buffered input and handles the power supply connections. PURIFI developed the FE02 stereo front-end module for this purpose. This module enables an evaluation setup but is also suitable for DIY applications. The FE02 front-end module is supplied with the PURIFI EVAL1 kit available on this page.

        2 x 4 1ET400A, die an DIY Buffer- und Spannungsversorgungplatinen (+-12V und 5V, extrem rauscharm) betrieben werden, erhalten die Musikdaten über zwei Hypex dlcp und einem Streamer der Fa. Auralic. Dieser Aufbau steht im Class-D-Vergleich zu 2 x 4 Ncore400-Einheiten. Beide Systeme treiben die selben 4-Wege DIY Open Baffle Lautsprecher sequentiell (durch umstecken) an. Auffällig ist, dass die Bühne mit den Purifi 1ET400A noch tiefer und ...
