Product details PURIFI FE07
PURIFI FE07 Deluxe mono front-end board for 1ET6525SA/1ET7040SA amplifier modules
The PURIFI FE07 is designed for integration in DIY constructions and provides the necessary front-end functions for operating compatible amplifier modules. It is suitable for use with the PURIFI 1ET6525SA and 1ET7040SA modules, giving builders a compact and practical way to connect, test and control a mono amplifier channel.
Connectivity is arranged for straightforward bench testing and system integration. The board includes a balanced XLR analog input, banana-plug speaker outputs and solder pads for an additional speaker connector, such as a SpeakON. It also provides connectors for enable and disable operation and for use with a shared power supply.
The FE07 includes an ultra-low-noise and low-THD pre-gain stage with four selectable gain settings: 3 dB, 11.6 dB, 13.7 dB and 17.2 dB. Ultra-low-noise linear voltage regulators supply the op-amp section, while status LEDs and various pin headers give access to functions such as I2C and status information.
With supply voltage support of ±35 V to ±70 V for VP, 15 V for VDR and ±18 V for VUNREG, the FE07 is built for serious amplifier development and integration. The board measures 75 mm x 63 mm x 39 mm and weighs 75 g. Adequate system cooling remains essential when the connected EIGENTAKT module is expected to deliver sustained high output power.
