Product details

PURIFI 1ET400A | Eigentakt | Amplifier Module

 

This high-performance amplifier module is based on the Eigentakt technology from PURIFI. 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.

Specifications

Specifications for: 1ET400A 1x425W Eigentakt Amplifier Module

  • Rated power output SPEC Rated power output

    425 watts at 4 ohms
    227 watts at 8 ohms
    450 watts at 2 ohms

  • Minimum load Shows the minimum load that an amplifier can control in ohms. A lower impedance of a speaker is not recommended if it is lower than the minimum impedance of an amplifier. An amplifier works best when the impedance of the speaker falss within the impedance range that the amplifier prescribes (for example, 4 to 8 ohms). 2 ohms
  • Efficiency SPEC Efficiency > 94%
  • Signal-to-noise ratio (SNR) Shows the strength level of signal power compares to a level of noise power. Generally, higher values ​​means better specification. 131 dB
  • Distortion Measured in Total Harmonic Distortion + Noise (THD+N). The lower this figure, the closer the output of the amplifier will sound to the original recording. 0.00017 % THD+N at 20-20,000 Hz, 4 ohms, 100 watts
