• Support Gain adjustment, the height of spectrum display height can be set at will, 0dB position can be set at random when recording is needed. The GAIN setting is controlled by the microcontroller internal digital adjustment, has no physical contact with the input audio signal then has no impact on sound quality.
• Support sensitivity adjustment, the spectrum beat rhythm can be quickly set to adapt to different music styles. Generally, slow rhythm corresponds to a slower beat, rock, punk and other fast-paced music is more suitable for the faster beat.
• Support ACG and DB two display modes: In ACG mode, the input volume and the swing of the light beam are not proportional. When the input volume is low, the swing amplitude of the light beam is large, and when the volume is gradually increased, the swing amplitude gradually becomes small. This mode cannot truly show the input level, not suits professional recording occasions but suits people's regular hearing habits.
• In DB mode, the swing of the light beam is proportional to the input signal. This display mode is suitable for some occasions that need to know the real music level, such as a recording studio or when testing a certain sound level.

Warm tips:

1. Please make sure you have installed the IN9 tubes incorrect direction, which must be consistent with the symbol on the motherboard, or else the tubes will not light up.
2. When you change the clear acrylic case, please make sure the pickup hole is right above the pickup head, or else the receiving distance will be reduced.
