Tweeter's level setting

The 3-step tweeter level setting allows to adapt the high frequency emission

to the complete car audio system and to the own taste:

•

0 dB = standard level

• - 3 dB = decrease the high frequency level

• +3 dB = enhance the high frequency level

Set the jumper by listening to the system with a well known music track,

then choose the position offering the best performances in your car.

Tweeter phase

Depending on the passenger compartment and mounting location, changing the polarity

of both tweeters can result in improved spatial reproduction; try to invert tweeter's positive

and negative wires (out of phase), then choose the position offering the best performances

in your car.

OAC - Off Axis Correction

The car audio performances depend from the system tuning, since each car passenger

compartment has different sound response. It comes from the speaker's position and the

reflections given from the materials used on passenger compartment.

The OAC control, by changing the speaker's response

and phase, adapt their emission to the passenger

compartment obtaining the best frontstaging.

By listening to the system with a well known music

track, try to alternatively change the jumper from

OFF to ON position of left, right or both channel

crossovers, than choose the position in order to

obtain the right sound in your car.
