High Performance Discrete Operational Amplifier

The DOPA520 is a Studio Grade Discrete Operational Amplifier Colour Module made with selected high quality components.

The design of DOPA520 was inspired by classic Discrete Opamp designed in USA. The original design was optimized for Mastering purposes and to achieve the superior audio performance.

The DOPA520 is using Vintage Silicon transistors in the input stage. This is another reason why the DOPA520 delivers outstanding tone shaping results.

The interferences from the 500 rack switch mode power supply may become real problem for professional studio applications.

On-board Voltage Regulators ensures the ideal operation conditions and filter-out any residual harmonics and interferences from the 500 Rack PSU.
