Loudspeaker Controls 
You will notice four control knobs on the back of the G4. These are 
labelled “BASS GAIN”, “LOW PASS”, “SOFT/BRIGHT” and “TIGHT/WARM”. 
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 and 
the low pass should be 115Hz. In general, these two controls are 
mirror-imaged. When you turn the bass gain to the left, the low 
pass should be turned an equivalent amount to the right.
