A pair of boards (“Balancer” and “Unbalancer”) which convert unbalanced and balanced audio signals back and forth.
BOM
Contact me if there are questions.
One application would be a frontend to a function generator which itself is single ended. Together with the “Balancer” board, that function generator would give a balanced output. When equipped with AD8033 and AD8034 OpAmps from Anolog Devices, the boards can be driven with 5V - 24V (center pin positive), so line level audio signals are easily produced.
The boards have the following input and output terminals:
- A common BNC connector
- Balanced XLR panel mount receptacles from the Neutrik D series, NC3MD-H (male) and NC3FD-H (female)
- Unbalanced TS mono jacks from Marshall, MESKTP00005
