The DOPA520 has a unique ability to enhance any audio signal by highlighting the details, amplifying the harmonics and adding space to the track.

The main use of the DOPA520 is the Mastering of the finished Mix when used in the mixbus section.

The DOPA520 can be used during the recording. Any signal source, instrument or vocal will benefit from the unique qualities of the DOPA520.

The DOPA520 will enhance the effect of any other Colour Module installed in the signal chain. Mastering Colour Bundles with DOPA520 are available at the discounted price.

The DOPA520 does not introduce any gain nor the phase shift and does not change the frequency response. It works its Magic thanks to the unique design and selection of high-quality components!

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 the USA. The 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 the real problem for professional studio applications.

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