      Product details

      PURIFI EVAL2 | Eigentakt | Mono Amplifier Kit 


      The 1ET400A amplifier module yields an audio quality level that sets the standard for power amplifiers of any operating class. The power supply and signal connections, available at the pin header on the1ET400A module, require special attention. This EVAL2 provides a buffered input signal and handles the power supply connections for a 1ET400A module in a convenient way.


      The kit is supplied with a 1ET400A amplifier module, one FE01 stereo front-end module and a power supply cable set. The FE01 front-end module allows you to easily connect a compatible power supply with the supplied cable set. The signal input is connected through XLR. A set of banana speaker connectors make connecting a speaker easy.


      The FE01 front-end module uses the OPA1612 opamp as pre-gain stage and buffer. The total gain for the EVAL2 (FE01 and 1ET400A) is 27 dB, but can set for a total gain of 14 dB. The opamp receive their supply voltage through a pair of onboard low noise discrete voltage regulators.


      The EVAL2 is compatible with the Hypex SMPS1200A400 configured with unregulated Vaux rails. The supplied cable set has pre-attached connector housings for the FE01 on one end. The other end has pre-crimped terminals with separate connector housings. This allows you to connect the EVAL1 with any compatible power supply. The pre-crimped terminals and supplied JST housings are compatible with the SMPS1200A400.
