How do I set the switch on the dipole?

Dipole setting: The speakers operate in phase opposition, i.e. if one side is transient, the other side dies out.

Bipole setting: The speakers operate in phase, i.e. both sides die out on the same side.

Monopole setting: Only the front side of the dipole is activated, i.e. the speaker works as a direct emitter.

On current dipole models (e.g. t 130 D) the two positions of the switch for the dipole and direct radiator mode are not specifically marked. If the switch is set towards the wall, the dipole mode is on. If the switch is set towards the speaker cabinet, the direct emitter mode is on.
