[3]The LINK OUTPUT is directly connected to the inputs of the B312A/B315A and carries the input signal with no processing applied. In this way, you can route the signal to the input of another device (for example, a second B312A/B315A)

[4]To set the volume of the LINE or MIC signal, use the LEVEL control. The left half of the control range is for attenuating the LINE signal. The right half is for raising the level of the MIC signal.

[5]The CLIP LED lights up when signal distortion occurs. Reduce the volume with the LEVEL control until the CLIP LED does not light up any more, or occasionally lights up at signal peaks.

For larger rooms, you can connect several B312A/B315A speakers using the LINK OUTPUT connector {3} (see fig. 3.1).

3.3 Direct connection of a stereo signal source

When you use two B312A/B315A loudspeakers, you can directly connect one stereo signal source, for example, a CD player.

In this case, each of the speakers is connected to 1 signal-sourceoutput. (If necessary, use the appropriate adaptor.)

Both audio inputs of the BEHRINGER B312A/B315A and the LINK OUTPUT connector are fully balanced. To maximize interference compensation, try to establish balanced connections to other equipment, whenever possible.
