MasterKeys Pro L White

For the Serious Professional

Improve your skills with the MasterKeys line of gaming keyboards and focus on pure performance in a straightforward package. We emphasize accuracy, precision, and performance - not flashy lights and superficial looks.

No Software Required

When you have a good thing going, the last thing you want to do is exit your game to adjust your keyboard settings. The MasterKeys Pro White keyboards use an innovative On-the-Fly system. Change your settings all from the convenience of your keyboard, without the need to download any software or exit your game.

A Vibrant, Functional LED Backlight

The MasterKeys White implements rich, bright white LEDs for direct solutions to some of pro gaming's biggest annoyances. A reflective metal plate built into the keyboard amplifies the brightness of the whites, allowing for more visibility of your keys during dim sessions. Multiple lighting modes include Light Wave, Breathing and unique responsive effects.

Fast, Seamless Performance

The MasterKeys Pro White is outfitted with a 32-bit ARM Cortex processor that powers the keyboard's independent functions. Make this power your weapon. Save and execute commands and macros instantly. Thanks to the MasterKeys On-the-fly system, you'll have an instant advantage on your opponents.

Macro and Profile Support

Trying to get familiar with a new game's controls? Light the relevant keys up to help you learn the in-game keybinds faster. With four profile keys, you can set up your backlighting and record macros without hassle. Program multiple keystrokes to a single key or change per-key backlighting with intuitive keyboard commands.

Status Indicator System

Know right on your board what settings you're running - simply press Fn+Esc and your repeat rate, profile, and other settings will be illuminated. Make sure you have that windows key lock activated so you don't accidentally open it when the fighting gets tense.

Effect Adjustment Keys

Alternate functions of the arrow keys allow you to adjust the effect you are using! The speedometer buttons change the effect's speed while the rotation icon stands for a change in the effect's motion direction.

Superior Accuracy

The MasterKeys White Series employs an exclusive combination of rollover technologies for the most efficient, accurate anti-ghosting technology yet. N-key rollover works in tandem with 6-key rollover to ensure that every single keypress is correctly detected, no matter how many are pressed. Rest easy knowing no matter how fast and furious it gets, your keyboard can handle it.

Shine in Your Own Way

A freely available SDK allows you to code further lighting options for your convenience. Use our SDK (Software Development Kit) and your C++ skills to create your own signature illumination effects. No worries necessary. Simple knowledge of C++ is sufficient. Stand out in the crowd and be the star of every event.
