New Audio Board Design

Optimized Line Level Output: There are two TRS (balanced) 1/4” stereo audio outputs on the back of the unit. Left channel can also act as a summed-mono channel.
Separate Headphone Output: A front panel features, a 1/4” phone jack with a dedicated rotating knob for headphone volume adjustment.
Dedicated Reverb: A commonly requested feature is now here!! There is now also a dedicated reverb knob on the front panel.
Inline Audio Merge: The malletKAT GS also has 1/4” stereo inputs that will merge its audio with the malletKAT. Now you can practice with other players or play with CD’s and hear it on your headphones or remote speakers.

Huge Sound library

The malletKAT GS is packed with an expanded collection of over 1000 instruments using over 14,000 samples. Moreover, these instruments were curated and tailored to respond to the articulations, gestures, and dynamics of a mallet player - not a keyboardist. You WILL notice a difference.
