OPERATION
1. Plug the AC cord into a grounded outlet (120
VAC, 60 Hz in North America, 220 - 240 VAC, 50
Hz in export models). Switch the PS210PX's
POWER switch OFF (for now).
2a. If you are using the (line-level) Main output
from your mixer to drive the PS210PX's inputs,
connect it to only one of the PARALLEL INPUT
connectors with a shielded patch cord
(eg.Yorkville model PC-6) or, if the mixer output is
balanced, with a balanced shielded patch cord
(eg. Yorkville model PC-6ST 1/4" TRS to 1/4" TRS,
or PC-6XPMS 1/4" TRS to male XLR). Now make
sure that the LINE/SPEAKER pushbutton is up in
the LINE position.
2b. If you are connecting the PS210PX as if it
were an extension speaker - i.e. to the SPEAKER
output of a mixer/amplifier - plug a speaker cable
into one of the 1/4" INPUT connectors. Make sure
that the LINE/SPEAKER pushbuttton is in the
SPEAKER position. Finally, set the SUBWOOFER
AMPLIFIER dB LEVEL control to "0".
2c. If you have a stereo source, whether it is a
mixer or an amplifier, connect only one output to
the PS210PX (left or right). This will prevent phase
cancellations.
3. To connect a second PS210PX, or another
powered subwoofer, run the appropriate type of
cable, patch or speaker-type, from one of the
remaining INPUT connectors to the input of the
another powered subwoofer. Be careful not to
connect speaker-level signals to the input of a
powered woofer which is not designed to take
them, and if you are connecting another PS210PX
this way, make sure that its pushbutton is also in
the LINE position. You can also connect an
unpowered subwoofers if you are driving the
PS210PX from the SPEAKER output of a
mixer/amplifier. Just run a speaker cable from the
remaining 1/4" INPUT to the unpowered
subwoofer. Now, that one will be powered by the
mixer/amp and the PS210PX powering its own
woofers (the PS210PX simply acts
as a convenient "Y" adapter so
that you don't have to run a
separate speaker cable from the
mixer/amp to the unpowered
subwoofer.
4. To power-up full range
speakers, simply run speaker
cables from the PS210PX
SATELLITE POWER AMP outputs
to the cabinets (no more than
two 8-0hm cabinets or one 4-
ohm cabinet). Now set the
SWITCHABLE CROSSOVER
FREQUENCY selector to the
appropriate position (see 3. Switchable
CROSSOVER FREQUENCY selector in the
FEATURES section. Finally, set the SATELLITE
AMPLIFIER dB LEVEL control to "0dB".
5. Switch on the POWER, and with music playing
through the system, adjust the two dB LEVEL
controls for the desired mix of subwoofer and full-
range sound. Remember that the subwoofer
volume may not increase greatly at settings above
0dB due to the limiter (see INTERNAL
SUBWOOFER LIMITER and AUTOMATIC
EQUALIZATION in the FEATURES section).
IN CASE OF FEEDBACK
In case of low-frequency feedback when the
mixer/amp or power amp is shut down:
The following applies where the PS210PX, in
SPEAKER LEVEL mode, and full-range speakers
are interconnected to the PA amplifier and that
amplifier has been switched off, but the
PS210PX left on.
With no power available at its inputs from the PA
amplifier, the PS210PX can receive random signals
in its PARALLEL THRU jacks generated by the full-
range enclosure's woofers responding to room
sounds (remember that every speaker is like a
dynamic microphone). If the PS210PX is powered
up and turned up high, it can see these signals as
input signals and amplify them creating a possible
feedback loop with the full-range woofers.
Solutions: If you are in the habit of switching your
power off between sets, it is advisable to switch
the PS210PX off as well, or turn down its LEVEL
control. Alternatively you might re-wire so that
the PS210PX is driven by line-level signals. Any
one of these measures will avoid the above
feedback potential.
