CONNECTORS, CONTROLS, AND INDICATORS:
LDSUB88A:
1 POWER SOCKET
IEC power socket 220V-240V with built-in fuse holder.
IMPORTANT INFORMATION: Replace the fuse only with a fuse of the same type and rating. If the fuse blows
repeatedly, please contact an authorised service centre.
2 POWER
On / off switch. Before switching the active speaker on or off, always adjust the volume to zero (SUB LEVEL
all the way to the left).
3 BALANCED LINE INPUT
Balanced line input (XLR / 6.3 mm TRS combo) for connecting an external audio source (e.g., mixer).
4 SUB LEVEL
Volume control
5 SUB CROSSOVER
Variable low-pass filter 70 - 140 Hz. Controls the lower limit frequency of the subwoofer.
6 SUB PHASE
Phase reverse switch for the subwoofer (0°, 180°).
7 POWER LED
Lights up when the subwoofer is switched on and properly connected to the power mains.
8 SIGNAL LED
The LED lights up when an audio signal is present at the line input.
9 LIMIT LED
Lights up if the speaker is operating in the clipping range. Brief flashing is not a cause for concern, since
the internal audio limiter compensates for over-modulation. Permanent illumination should be avoided by
reducing the input level.
