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. Phase Control Switch
The phase control switch will flip the sub's phase by 180°, this is desirable in certain
cases when you need to reduce (or increase) the response at the cross over point
between the monitors and the subwoofers.
7. Foot switch Control
In some cases it is desirable to shut off the output from the sub in order to listen to the
monitors only for editing purposes, this can be done by adding a foot switch to the foot
switch jack at the back of the unit.
8. Crossover control
This control can adjust the crossover point desired between the monitors and the sub,
it can control the frequencies between 50 to 200 Hz, this will optimize the response at
required cross over point..
9. Protection and Indicators
The YSS10 has circuitry to prevent clipping, over-current and over-excursion. At high
levels, the internal limiter will limit the gain of the YSS10; 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 sig-
nal 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.
