User Guide     Data Sheet


EVAL3 is an evaluation kit consisting of one amplifier module (1ET7040SA) and a mono front-end board (FE03). EVAL3 is also very suitable for integration in DIY constructions.
The front-end FE03 is designed for easy testing of the 1ET7040SA and provide all connectivity and control required to operate the amplifier modules:

  • Balanced analog input connector (XLR),
  • banana-plug speaker connectors,
  • toggle switch for enabling/disabling operation,
  • connecters for power supply,
  • voltage regulators for OPAMPs,
  • Pre-gain stage w/ bypass option (jumpers),
  • status LED’s,

Refer to the 1ET7040SA Data Sheet for all specifications.
It is recommended to mount EVAL3 on a heatsink, e.g., an adequately design aluminum chassis.

NOTE: 1ET7040SA has very low idle losses and high overall efficiency, however, adequate cooling is still essential for sustained power delivery. Careful considerations must be given to design of the thermal system in order to achieve desired system-level output power specifications. Given proper cooling the 1ET7040SA amplifier module can easily be capable of very high continuous power delivery and the module is specifically designed with the utmost robustness and reliability as fundamental properties. Most frequently it is the system power supply that becomes the limiting factor in a application incorporating the 1ET7040SA module(s).
