Headphones Recommended – Just a fun little sound experiment with our lizards food. I attached 2 – 35mm piezos to a small tub of meal worms via my Dual OPA field buffer and then into the trusty Mix Pre 6 II – kind of what you would expect, lotsa scratchy little legs in the saw dust.
More on the Dual OPA Field Buffer
The Dual OPA Buffer has just that, two impedance buffer circuits using the Texas Instruments OPA1642 opamps. These are the exact same high-quality buffer circuits I am using inside my hydrophones. These devices will be available for sale soon, P48 Required.
