The Harp Sound Amplifier peripheral is a low distortion, high bandwidth audio amplifier for use in high fidelity applications to drive high-quality sounds to speakers using the OEPS-1280 Harp Sound Board.

  • Drives any mono audio speaker between 4 and 8 Ohms

  • Physical on/off switch for quick interruption

  • 2x Out (+/-) for speakers [4mm banana]

  • 1x In for connection to Harp Sound Board [RCA]

  • 2× 12V power supply input jacks

An in-depth application of the Harp Sound Board and Sound Amplifier can be found in this article.

This Harp peripheral needs to be connected to a Harp device to achieve its intended function. Multiple Harp devices can be connected to a Harp Timestamp Generator or Open Ephys Acquisition Board (3rd Generation) to continuously self-synchronize so that they all share the same acquisition clock. Check out this overview of Harp devices and peripherals available in our store.

Please also check the device connectivity list to purchase any cables, tethers and power supplies you might need to operate the device.
