5AMPLIFIER ADJUSTMENTS (CONTINUED)

“AUDIO” Setting senses a music signal to turn on the ampliﬁer built in to

the ST series subwoofer. This setting is recommended for earlier model Wet

Sounds Stealth Sound Bars. Please note – if the source unit is powered ON,

but at “0” volume, the ST series subwoofer will likely not turn on until the

volume is increased.

2 - The Gain adjustment controls the sensitivity of the ampliﬁer built in to

the ST series subwoofer. It has been included to allow adjustment to match

the output of any source unit to the input of the ampliﬁer. Gain controls are

one of the most misunderstood adjustments. By rotating the control in the

clockwise direction, the ampliﬁer’s input will become more sensitive and the

subwoofer output will increase.

To determine if the ampliﬁer’s gain control is set properly, turn the

system on and slowly increase the volume control on the source unit.

Usually about ¾ volume can be reached before the system gets loud without

distortion. It is very important to not overdrive the subwoofer to the point

of distortion, which will cause permanent damage to the subwoofer. If ¾

volume without distortion is not possible, the gain should be reduced (by

decreasing the gain adjustment). Gain adjustments should be done very

slowly and carefully. The Remote Level Control should be unplugged while

the gain is adjusted, then plugged in after ﬁnal adjustments are made. The

Remote Level Control will only decrease the output of the ampliﬁer and will

not affect the gain control setting.

ADJUSTING THE X-OVER, BASS BOOST AND PHASE

3 - The Variable Crossover Network allows adjustment of the frequency

range that the ampliﬁer sends to the subwoofer. This should be adjusted to

fall slightly above the lowest frequency that the full range speaker/s in the

system can reproduce.

4 - The Variable Bass Boost allows the selection of the amount of bass

boost – centered at 45Hz - that is desired in the system. There is no speciﬁed

setting for this. It is suggested to be set by the listener’s preference.
