5. LINE OUT: XLR output to another active speaker
6. BI-AMP PARALLEL OUTPUT: NL4 connector to link a passive speaker of the same power rating
7. HF & LF Clip indicator: When the signal levels of the BI-AMP output for the HF (high frequencies) & LF (low
frequencies) approach clipping, a soft limiting circuit is activated that reduces the input signal. The LEDs light up
whenever the circuit is activated. It’s OK if the LEDs light up occasionally but if they blink frequently or continuously,
either turn down the signal level at the BASS or TREBLE, or turn down the MAIN VOLUME control of the speaker.
8. POWER INDICATOR: Lights up when the box is connected to a mains power supply and switched on.
9. POWER SWITCH: Press the upper part of the switch to turn the system on. Make sure the MAIN LEVEL control is
down before you turn it on. Press the bottom of the switch to put the speaker into standby mode. It will not function
but the circuits are still live. To remove AC power, either turn off the AC mains supply or unplug the power cord from
the speaker system and the AC mains outlet.
10. Fused IEC mains inlet: Connect the supplied lead to this inlet and the other end to a suitable mains outlet.
11. FUSE RECEPTACLE
In case of a "blown fuse" do not attempt to remove or replace fuse while the unit is powered on.
Replace the fuse only by an identical fuse that has the same size and the same specifications.
