C2584 is a Dual Mono (Stereo) Colour Processor unit which fits in a single 500 rack space. C2584 can be used for Mastering and to process line-level signals from DAW or electronic instruments.

Each Channel has 2 Colour Module Slots compatible with DIYRE Colour Format – 4 Colour Modules in total per single 500 rack space.

Left and Right channels can be connected in series (with additional TRS cable) to use all 4 Colour Modules in Mono configuration.

Left and Right channels have separate balanced Line Inputs on the Front Panel. Pair of standard TRS cables are required to process the stereo signal or two independent tracks.

Use your favourite Colour Modules to do the Mastering of your finished Stereo MIX.

C2584 is Easy to Use!

Each Channel has INPUT LEVEL control knob and OUTPUT LEVEL control knob. Each of the 2 Colour Modules (per channel) can be bypassed by individual Bypass Switch. Each channel has a total gain of +18dB.

The level of the signal which is sent to the Colour Modules is controlled by the INPUT LEVEL (L or R) knob. The OUTPUT LEVEL (L or R) knob controls the level of the output signal from the Colour Modules, which is also the output level of the C2584 unit.

All control pots are carefully matched to ensure correct stereo operation. C2584 is perfect for post-processing and Mastering!

The C2584 has High Headroom balanced line inputs based on Studio Grade Texas Instruments operational amplifiers.

You can safely send hot signals from your DAW system to saturate Colour Modules.

Return Policy

Our return policy is a part of the general Terms & Condition which you have to acknowledge at the checkout.

We stand for fair rules and a win-win approach. We understand that our customers may wish to return the product and we do provide such option. However, because we are a small company we can’t afford to run a grade B outlet shop like big distributors and provide the 30 days return period.

We can’t also scrap every returned unit. We could charge our customers more to offset the cost of the returns, this is what major distributors do. Or we can keep our prices low and hope that our customers will appreciate our policy.

This is why we provide the 7 days test period after receiving the package with the ordered items and if you wish to return the item we will accept the return request, providing that the item is not damaged and we can resell the product with the minimal loss for the company.

If the item is damaged during the transport we will do our best to help you and provide the replacement product.
