前面板 / 顶部面板说明
INPUT JACK — Input jack for your bass. We suggest using a good quality cable, to obtain the best audio performance.
DRIVE BUTTON — Increases and reduces the distortion created by the tubes by making them work in different ways
TONE FILTER — To activate an eq. mid scooped Filter)— Scoop),
GAIN CONTROL KNOB — Sets the input signal amount of the pre-amp
DEEP BUTTON — Gives a more deep sound
LOW KNOB — Increases or reduces the bass frequencies of the signal
MID-Low SWITCH — Use this switch to change the frequency of the mid-low band from 220 Hz and 620 Hz 220Hz 620Hz
MID-Low KNOB — Increases or reduces the mid-low frequencies of the signal
PURE SWITCH — Allows bypassing all the equalization filters of the preamplifier. The pure-mode activation is signaled by the LED on the top of the button LED
MID-High KNOB — Increases or reduces mid-high frequencies of the signal
MID-High SWITCH — Use this switch to change the frequency of the mid-high and from 720 Hz and 1750 Hz 720Hz 1750Hz
HIGH KNOB — Increases or reduces the high frequencies of the signal
BRIGHT BUTTON — Gives a more bright sound
DI KNOB — Controls the DI volume DI — DI
PRE-POST DI BUTTON — Allows you to choose the type of signal to be sent to the DI output DI: PRE EQ or POST EQ DI DI EQ( POST EQ(
HEADPHONES KNOB — Controls the headphones volume
AUX-IN JACK — 3.5mm jack Auxiliary input to connect an external audio device 3.5mm
HEADPHONES OUTPUT — 3.5mm plug for headphones 3.5mm
MASTER KNOB — Controls the overall volume of the channel
OPERATION LED — Blue = normal operation – Red = high level of the input signal (clip) = =
MUTE BUTTON — Turn off the amplifier output. The activation of this mode turns on the red LED on the left of the button. In this mode, the Tuner is always on, whatever LED mode is on LED LED
VU-METER — 24 LEDs that can be used as VU-METER. The LEDs turning red do not indicate that the signal is clipped. The only LED that indicates if the signal is CLIP is the operational LED VU — 24 LED VU LED)。
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
