Linking
It is possible to link one active speaker to another.
1.
Connect your signal cable to the active speaker using one of the line in sockets (11) or (12).
2.
Connect a lead from one of the line out sockets (8) or (9).
3.
Connect this lead to the line in socket (11) or (12) of the next active speaker.
Please note you cannot connect a passive speaker to this output.
Tone controls
To adjust the tone, bass, mid and treble use the 5 band graphic equaliser to adjust the sound to your personal
taste (Soundforce 15A only). If you are using a Soundforce 12A use the bass and treble controls.
Clip LED
If the clip light is flashing ocassionally this is ok but if the clip light is illuminated constantly or distortion is heard
from the speaker, reduce the master output volume, adjusting the graphic equaliser will normally allow you to
increase the output level but reduce the clip limiter or distortion
