LED/FAN BUTTON — By pressing this button you can: – scroll through the four VU-Meter display modes, – turn off the 24 LED bar, – turn off the Fan. The last selection made on this button is always memorized. In the GROOVE 800 and GROOVE 1200 amplifiers, holding down the LED button for about 8 seconds, the fan turns off (STUDIO MODE). To reactivate the fan (LIVE MODE) you must hold down the LED button for about 8 seconds or turn off and turn on the amplifier. In “LIVE” mode, the fan automatically activates when a preset temperature is reached. In “STUDIO” mode the fan is always switched off, except when a critical temperature is reached. In that case the fan automatically reactivates. LED/ — VU 24 LED 800 GROOVE 1200）： LED 8 STUDIO 8 LIVE
