SAFETY INFORMATION
Warning
Any person performing service of this unit will be exposed to
hazardous voltages and the risk of electric shock.It is
assumed that any person who removes the amplifier from
this cabinet has been properly trained in protecting against
avoidable injury and shock.Therefore, any service
procedures are to be performed by qualifiedservice
personal ONLY!
Caution
This unit does not have a power switch. Hazardous
voltages are present within the unit whenever it is
plugged in.
Before the amplifier is plugged in, be sure its rated voltage
corresponds to the voltage of the AC power source to be
used.Incorrect voltage could cause damage to the
amplifier when the AC power cord is plugged in. Do not
exceed rated voltage by more than 10%: operation below
90% of rated voltage will cause poor performance or may
shut the unit off.
Leakage/Resistance Check
Before returning the unit to the customer, perform a leakage
or resistance test as follows:
Leakage Current. Note there is no power switch on this unit.
When the power plug is plugged in, the unit is live. Connect
the unit to its rated power source. Using an ammeter,
measure the current between the neutral side of the AC
supply and chassis ground of the unit under test. if leakage
current exceeds 0.5mA, the unit is defective. Reverse the
polarity of the AC supply and repeat.
Resistance. Measure the resistance from either side of the
line cord to chassis ground. If it is less than 500k ohms, the
unit is defective.
WARNING! DO NOT return the unit to the customer if it fails
one of these tests until the problem is located and corrected.

PSW-D110/DPS-10 CONTROLS AND THEIR FUNCTION
1. Power - (PSW-D110 ONLY) This light will be RED
when the unit is plugged in and not receiving a signal;
when the PSW-D110 receives a signal, the light will cycle
to GREEN. If no signal is received after 10 – 15 minutes
the light will cycle back to RED (standby) until a signal is
present again.
2. Level Control - The subwoofer Level Control,
(PSW-D110, located on the front panel, DPS-10, on the
rear panel) adjusts the volume of the subwoofer relative
to the rest of the system.
3. High Pass Control - Controls the the roll-off point of
the highest frequency the subwoofer will produce.
4. Phase Switch - Changes the subwoofer's output to be
in phase or 180 degrees out of phase with the program
material.
5. Low Pass Control - Controls the roll-off point of the
lowest frequency produced at the High Pass Output
Jacks.
6. High Pass Output - When using the Line-Level Input
jacks, these are connected to an external power amplifier
or receiver to power the main loudspeakers with a high
pass filter if desired.

OPERATION
Crossover Adjustments
High-Pass Control
• This control is only active if you are using the hook-up
method described in detail on page 8, Figure 3. The
High-Pass control determines the frequency at which the
main speakers will start reproducing sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, also set this control to a lower frequency setting,
between 50Hz – 100Hz. This will concentrate the
subwoofer’s efforts to the ultradeep bass sounds, while your
main speakers continue to reproduce the mid-bass
information. If you are using smaller bookshelf speakers
that do not extend to the lower bass frequencies, set the
high-pass crossover control to a higher setting, between
125Hz – 180Hz. With this setting, your main speakers will
not have the burden of reproducing any low-frequency
sounds.
Final adjustment and blending of the low-pass and
high-pass controls may evolve over several listening
sessions. A good starting point would be to set both the lowand high-pass controls to the same frequency and adjust
from that point.
Low-Pass Control
The Low-Pass control determines the highest frequency at
which the subwoofer reproduces sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, set this control to a lower frequency setting,
between 50Hz – 100Hz. This will concentrate the
subwoofer’s efforts on the ultradeep bass sounds required
by today’s films and music. If you are using smaller
bookshelf speakers that do not extend to the lower bass
frequencies, set the low-pass crossover control to a higher
setting, between 120Hz – 180Hz.
Phase
Phase Control
The Phase Control determines whether the subwoofer
speaker’s piston-like action moves in and out with the main
speakers, 0° , or opposite the main speakers, 180° . There is
no correct or incorrect setting. Proper phase adjustment
depends on several variables such as room size, subwoofer
placement and listener position. Adjust the phase switch to
maximize bass output at the listening position.
Remember, every system, room and listener is different.
There are no right or wrong settings; any setting you choose
will result in excellent performance. Should you decide to
fine-tune your system for optimum performance, be patient
and trust your ears. It will be worth the effort involved to fully
“tweak” your system.

This method of hookup can offer the highest level of
performance for your complete loudspeaker system. The
PSW-D110/DPS-10 incorporates a variable high-pass
crossover in addition to a variable low-pass crossover.
When hooked up as shown above, the subwoofer will limit
the low-frequency information that is returned to your
receiver/amplifier. Your receiver/amplifier does not need to
waste valuable power reproducing the low frequencies. In
addition, since no low-frequency information is being sent to
your main loudspeakers, they are able to reproduce mid and
high frequencies with greater clarity
