Mains Section - Stagg SPA-SUB 1208 EUR User Manual

CONTROLS
5. SUB WOOFER LEVEL: This control determines the volume of the low frequencies .
6. CLIP LED: This 3 colour LED shines green as long as the limiting device is not "limiting" the low signal. The
LED shines orange when the signal starts to be limited to avoid distortion. This happens when the signal to the
output power stage becomes too loud. When the limiter performs to its maximum the LED permanently lights up
red; it indicates distortion that could be harmful for the speakers. This means that one or more levels are set too
high and should be at once re-adjusted until the led fl ashes again or shuts off.
7. Phase inverter: As the name suggests it inverts the phase of the signal. When speakers perform not in
phase some information will be acoustically lost. (for example: one speaker moves forward and at the same time
an other moves backward, the result is that little air moves and the volume will be low)
8. MID - HIGH LEVELS: These controls determine the volume of the mid high frequencies sent to the satellites.
9. CLIP LED's: These 3 colour LED's shine green as long as the limiting device is not "limiting" the mid high
signals. The LED's shine orange when the signal starts to be limited to avoid distortion. This happens when
the signal to the output power stage becomes too loud. When the limiter performs to its maximum the LED
permanently lights up red; it indicates distortion that could be harmful for the speakers. This means that one or
more levels are set too high and should be at once re-adjusted until the led becomes orange or green.
10. GROUND LIFT: With ground lift you can eliminate or reduce noise generated by earth loops. Earth loops
happen when equipment is earthed on several places and current fl ows in the cable shields. So by pushing the
button you can interrupt the earth connection. For safety reasons, make sure that one earth connection is left
in place.

MAINS SECTION

11. POWER SWITCH: This switch turns the active speaker set on or off. When on, the power LED on the top
lights up.
12. POWER FUSE: In the event of the power fuse having to be replaced, fi rst unplug the power cable from the
mains outlet. Then remove the fuse cover and replace the power fuse with one of the same type and value. Never
plug the power cable back into the mains outlet without the fuse cover. When powering on the amplifi er, if the
power fuse blows up again, go to a suitable service centre for repair.
13. AC (MAINS) INPUT: This is the input socket into which the moulded mains power cable must be connected.
If the socket outlets available are not suitable for the plug supplied with this equipment, use an appropriate plug
adapter that can handle the power required for this powered speaker.
14. FAN: This fan will cool the 3 power amplifi ers that are built in .
15. POWER LED: Is lit up when the SPA SUB PA speaker set is switched on.
