Know before you buy
The MR3eq is designed to replicate the classic, smooth, and velvety sound of vintage Harrison consoles. It adds a subtle, silk-like warmth to your signal, making it ideal for polishing vocals or adding character to instruments without sounding harsh.
The proportional-Q design automatically adjusts the bandwidth based on how much you boost or cut. When you make subtle adjustments, the bandwidth is wider and more musical; as you increase the gain, the bandwidth narrows, allowing for more surgical, precise frequency shaping.
Yes, both the HI and LOW bands are switchable. You can toggle between a shelving response, which is great for broad tonal shaping, or a bell response, which allows for more focused frequency targeting.
It is excellent for both. Because of its musical, console-style response, it works perfectly as a tracking EQ to shape your source material before it hits your DAW, but it is equally effective on the mix bus or individual channels during the mixing stage.
No, the highpass filter is variable, allowing you to sweep the corner frequency anywhere from 25Hz to 3.1kHz. This gives you significant control over removing low-end rumble or cleaning up muddy frequencies in your source material.
Yes, the MR3eq is a standard single-slot 500 Series module. It is compatible with any industry-standard 500 Series chassis that provides the necessary power.
