YSS1
2
The male XLRs are balanced "through" connec-
tors. This way the source output can go directly to
the YSS1 then be patched through to the input of
the full-range amplifier or powered speakers with
the appropriate cables. For powered speakers or a
power amplifier with balanced inputs, use balanced
cables with a female XLR on the YSS1 end and
the appropriate connector (TRS ¼-inch or male
XLR) on the other end. Unbalanced signal may
also be passed through using modified patch cords
with a female XLR on one end (pin 1 to shield, pin
2 to center) and a mono ¼-inch jack or male RCA
connector on the other end.
Controls
The YSS1's Volume control should be set while
program is playing through the full-range speak-
ers at the maximum volume you expect to employ.
Adjust the YSS1's Volume control until the desired
balance of lows and full-range level is achieved.
Thereafter the signal level from the source will
determine the subwoofer's volume so that sub
and full-range sound levels remain in balance.
Naturally adjustments can be made at any time.
The YSS1 has a low-pass filter, which affects
the A&B Output signals and is regulated by the
Variable High-Pass control. This is a feature,
which enables you to match the upper frequency
range of the sub with the lower frequency limit of
the full-range speakers for the smoothest sub/low
transition. If you have an accurate response graph
of the full-range speakers, set the YSS1's Variable
High-Pass control to the frequency on the graph
where the lows have rolled off -3dB. Otherwise, simply adjust the it for the desired
smoothness of response throughout the sub/low-frequency range while program
(music, video, etc.) or test tones are playing. If necessary, re-adjust the YSS1 Volume.
The phase relationship between subwoofers and full-range speakers can make a notice-
able difference in overall low-mid response smoothness. To reduce low-mid presence it
sometimes helps to invert the sub's phase 180 degrees thus creating an audibly more
defined separation between the two types of enclosures. To achieve this simply set the
YSS1's Phase button to the 180 position. Otherwise you would use the Normal position.
Footswitch Jack
From time to time you may need to shut the subwoofer off in order to hear the pro-
gram as it sounds to someone who does not have a subwoofer, or to let you concen-
trate more on mid-to-high frequency music components - vocals for example. The
Footswitch jack accepts a standard on/off footswitch without an LED. When connected
and engaged, the footswitch will mute the output of the YSS1 and bypass the high-
pass filters on the A & B Outputs. This way the sub frequencies are cut off and the
full-range amplifier or powered speakers return to full-range operation.
