The PURIFI EVAL11 Deluxe Stereo Eval Kit is a two-channel evaluation platform built around two 1ET7040SA amplifier modules and the FE08 stereo front-end board, offering balanced XLR inputs, speaker output connectivity, control access, and high-power performance for advanced amplifier development and DIY integration.
PURIFI EVAL11 Deluxe Stereo 1ET7040SA Evaluation Kit
The PURIFI EVAL11 is designed as a complete stereo evaluation kit for the 1ET7040SA platform. It combines two 1ET7040SA amplifier modules with the FE08 stereo front-end board and a cable set, giving you the essential hardware for testing, integration, and system development in a compact two-channel layout.
The FE08 front-end board provides the connectivity and control required to operate the amplifier modules. It includes balanced XLR analog inputs, banana-plug speaker outputs, solder pads for additional speaker connectors such as SpeakON, connectors for a shared power supply, status LEDs, and pin headers for access to functions such as I2C and status information.
Performance-focused features include an ultra-low-noise and low-THD pre-gain stage with four gain settings using PURIFI’s FET-input discrete op-amp topology. The board also includes ultra-low-noise linear voltage regulators for the op-amps and a pin header for connecting the 1ET7040SA module in BTL mode, making it a flexible platform for serious amplifier evaluation and development.
The EVAL11 supports 500 W output power at 1% THD into 4 Ω and operates with ±35 V to ±70 V VP, 15 V VDR, and ±18 V VUNREG supply rails. For sustained power delivery, it should be mounted to a heatsink, such as a properly designed aluminium chassis. Its low idle losses and high overall efficiency help system design, but adequate cooling remains essential when integrating it into DIY amplifier kits or custom builds.
