The GROOVE series takes up and perfects the philosophy of PURE SOUND, a fundamental characteristic of GR products, with the possibility of adding the characteristic sound only valves can give you.
A 4-band equalizer will allow you to sculpt the sound according to your needs but that’s not all: you can choose 4 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 exclude filters and equalizer and have a completely flat sound to be combined if necessary with an external equalizer, a very useful function when using different instruments in a concert. Two Aux-Ins, a standard front one that you can listen to directly in the speaker, and one on the back, with an XLR input that will allow you to have this signal only through the headphone output. You can use the GROOVE as a mixer between you and the PA.
The headphones output has a separate volume control, it also allows an independent monitoring system. The D.I. of GR, recognized as one of the best, is perfect for use in professional contexts both live and in the studio.
