SKU: OEPS-1280

The Harp Sound Board device is a high performance, low latency stereo sound card that links to the OEPS-1282 Harp Sound Amplifier peripheral to control speakers for audio stimulation with complex stimuli.

• Controls up to two OEPS-1282 Harp Sound Amplifier to create mono or stereo sound 24 bit at 192 kHz maximum sampling rate

• Store up to 30 audio files on internal memory for low-latency sound delivery, or generate pure tones on-the-fly with onboard frequency generator

• Trigger pre-selected sounds using external TTL

• Sound amplitude can be controlled in real-time

• 3× digital inputs 5V tolerant (IN0-IN2) [screw terminal] to externally trigger the device

• 3x digital outputs 3.3V or 5V (OUT0-OUT2) [screw terminal] to trigger external hardware

• 2x analog input (5V) from additional sensors (AO0, AO1) [screw terminal]

• 1x timestamp input for Harp synchronization (Clk In) [3.5mm stereo jack]

• 1x USB2.0 for connection to the PC [mini-B USB]

• 1x USB3.0 for loading sounds [micro-B USB]

• 1× 12V power supply input jack

• Runs in Bonsai, a free and open-source visual programming language, or using a dedicated app for standalone use

This Harp device needs to be connected to a Harp peripheral 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.
