[efendija80]

Moze li mi netko malo pojasniti cemu tocno sluzi ovaj prekidac na navedenoj yamahinoj mikseti i kakav na kraju utjecaj ima na ove klizace AUX1, AUX2 i ST?
U sluzbenim uputstvima stoji sljedece:

Selects the output that gets sent to the SPEAKERS
jacks, as follows.
L/R:
SPEAKERS jacks A1 and A2 output the signal from
the Stereo L bus, while jacks B1 and B2 output the signal
from the Stereo R bus. The overall volume is
adjusted by the ST master fader.
AUX1/MONO:
SPEAKERS jacks A1 and A2 output the signal from
the AUX 1 bus; the volume for this signal can be
adjusted using the AUX1 fader. SPEAKERS jacks B1
and B2 output the mix of the signals on the Stereo L
and R buses; the volume can be adjusted with the ST
master fader.
AUX1/AUX2:
SPEAKERS jacks A1 and A2 output the signal from
the AUX 1 bus, while jacks B1 and B2 output the signal
from the AUX2 bus. Volumes can be adjusted using
the AUX1 and AUX2 faders, respectively.

Ovo A1, A2, B1 i B2 su ulazi sa straznje strane za zvucne kutije koliko vidim po oznakama. Ako sam dobro razumio onda bi ovisno o odabiru jedne od ove tri mogucnosti dobio razliciti nacin pojacavanja, tj reguliranja lijeve i desne strane, al nije moja mikseta pa me opet strah nekako sam vrtiti sto nisam sto posto siguran pa molim da mi neko pomogno tko ima iskustva s ovom miksetom. Sad je namjestena koliko vidim na ovu prvu opciju, L/R, stvar je u tome sto ne kuzim kako da reguliram lijevu i desnu stranu, jacinu?
