4. High Pass Output Jacks
High Pass Output jacks are provided to eliminate the need for an external crossover. Use
these jacks to feed the input of your full-range loudspeakers. The signal leaving these XLR
jacks has had the audio below 80 Hz removed, allowing for a flat system response when
feeding the full-range loudspeakers.
5. Ground Lift Switch
In normal operation, keep the Ground Lift switch in the depressed position. If an audible hum is
present in your system, try “lifting” the ground to break a ground loop in your system.
6. Protection and Indicators
The YX18SP has circuitry to prevent clipping, over current and over excursion. At high levels the
internal limiter will limit the gain of the YX18SP and hence if the user attempts to set the subwoofer
level control at a high level, the resulting setting will be incorrect. The level control should be set
while operating at low levels (under 10 watts). If the level control is set too high, the input circuit
will clip and the dynamics of the bass will be lost.
In normal operation, the rear indicator will flash green when a signal is present. When the
indicator starts flashing red, the limiter is engaging. Increasing the input signal beyond this point
will potentially result in clipping.
AT HIGH POWER LEVELS WHEN THE LIMITER IS OPERATING INCREASING THE SUBWOOFER
LEVEL CONTROL WILL NOT INCREASE THE OUTPUT. DO NOT INCREASE SETTING WHILE
OPERATING AT HIGH LEVELS.
