4.3 connecting sources and setting the input sensitivity the vl3x0 features universally usable inputs. Depending on the intended application, e.G. Micro- phones or keyboards the individual channel sensitivity is set by the illuminated mode buttons (2) and (5) (→ see illustration 2.2). At the same ti...

Connection possibilities and input modes this section explains the modes and properties of the individual channels. Channel 1 • mode „mic“ → suitable for microphones and low level sources this mode offers a maximum gain of 50 db which can be set via the channel volume control. • mode „p48“ (phantom ...
Page 15
Channel 2 – instrument / line / mic though channel 2 offers universally usable inputs its key function is instrument and line-level amplification. For this purpose it is equipped with two 6,3mm jacks. As the gain of xlr i ranges up to 20 db the amplification of most standard microphones is also feas...

• mode „line / other“: → this mode enables line level sources to be amplified via • jack ii with a maximum gain of 30 db • jack iii with a maximum gain of 10 db • xlr i with a maximum gain of 10 db. If both jack ii and iii are connected their sensitivity will be automatically set to line-level provi...
