Lightweight, portable yet powerful, the GR ONE series will amaze you with its incredible quality and power. The ONE series revisits and perfects the PURE SOUND philosophy, a fundamental characteristic of GR products. A 4-band equalizer will allow you to sculpt the sound according to your needs, but that's not all: you can choose 6 frequencies for the mids, and the deep and bright filters will allow you to add punch and/or definition to the equalization. Through the "PURE" switch, you can bypass the filters and equalizer and have a completely flat sound to combine if necessary with an external equalizer, a very useful feature when using different instruments in a concert. The 24-LED meter in 6 different modes (which can also be bypassed if necessary) also incorporates an extremely precise tuner, always active in "Mute" mode or activated during normal use, choosing it among the six available LED modes. The auxiliary input allows you to connect an external sound source (Tablet, Smartphone). The DI of the GR ONE, recognized as one of the best, is perfect for use in professional contexts both live and in the studio.
