Loudspeaker Controls 

You will notice four control knobs on the back of the G2jr. These 
are labelled “

BASS GAIN

”, “

LOW PASS

”, “

TWEETER

” and “

MIDRANGE

”. 

Set them initially pointing straight up 

– the 12 o’clock position. This 

is the nominal flat position and will work for the majority of 
installations. For a minimum-sized room, the bass gain should be 
set at 3 (the 9 o’clock position).
