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 feasible.
Simultaneous connection of both XLR and 6,3mm jacks is not beneficial
Since all inputs of channel 2 are affected by the same volume control you should either use the
XLR or 6,3mm jack exclusively.
As a guideline the possible input connections with their corresponding modes are listed on the
input panel:

Illustration 4.3: Connection guidelines
The 6,3mm jacks II and III accommodate a variety of functions:
The summation of unbalanced stereo signals such as Keyboard outputs. For this purpose,
•
connect left and right channel to one 6,3mm jack each. The combined connection of both
6,3mm jacks is automatically detected as a line level signal input.
The amplification of mono signals with Line-level. Here, jack III should be used.
•
High-Z sources such as Guitars equipped with passive pick-up electronics can be connected
•
to jack II.
This high impedance input is especially suitable for this purpose since it will preserve the sig-
nal integrity. If High-Z pick-ups are shown low impedances they may suffer from high cut and
general level attenuation. This input will preserve the tonal characteristics of your instrument.
Mode „INSTRUMENT A-GUIT" / „INSTRUMENT E-GUIT"
•
→ For use with electric or acoustic guitars with jack II
Applying this mode will adapt the input sensitivity and tone control characteristics to the needs of
guitars.
