The easiest way to remove the amplifier from its carton is to turn the open end of the box
down so that it is resting on a table or the floor, with the flaps spread out and away. Then
pull the box straight up and off. Remove any packing material from the amplifier, place it
back in the carton, and store in case you ever need to ship the amplifier.

The Master Power switch turns the amplifier on and off. In addition to the Master Power
switch, the KA-1000-THX has an Auto Power function that will allow the amplifier to turn
itself on and off automatically when an audio signal is detected. An LED indicates the
current status of the amplifier – RED when the amplifier is in Standby and GREEN when the
amplifier is active. The LED is off when the Master Power switch is set to the “Off” position.

The Auto Power switch has two settings – “On” and “Off”. In the “Off” position, the Master
Power switch turns the amplifier on or off. If you leave the Master Power switch in the “On”
position and set the Auto Power switch to the “On” position, then the amplifier will automat-
ically turn itself on and off when an audio signal is detected. There is a 2 second On delay
and a 15 minute Off delay when using the Auto Power function.

The Phase control on the KA-1000-THX is continuously variable from 0˚ to 180˚. This
control allows you to fine tune the performance of your subwoofer system by o p t i m i z i n g the
blend with the main speakers. Basically, one of the positions will result in an audible
increase in bass output depending upon room placement.

The Boundary Gain Compensation switch allows you to fine-tune the low-end extension of
your subwoofer system based upon room placement. In some room locations, your
subwoofers low-end response may become exaggerated or boomy due to the increase in
output from your room’s acoustics. In this case, selecting the “On” position will restore the
system to a flatter, less boomy response. If you are using a THX
®Ultra2™receiver or
processor and you have selected “Ultra2” for the sub setting, the boundary gain compensa-
tion switch should be set to “Off.”

The THX switch provides a means to bypass the crossover and level controls when using a
THX preamplifier or receiver. In the “On” position, the crossover and level controls do not
function. (In this configuration, your preamplifier or receiver will perform those functions.) In
the “Off” position, the crossover and level controls operate normally. Be sure the volume
level on your preamplifier or receiver is turned down before changing the setting of this
switch.

The Lowpass Crossover control allows you to select the proper frequency at which your
subwoofer system blends with your main speakers. It is selectable from 40-120Hz. You
should set this control to the approximate low-frequency limit of your main left and right
speakers. In a THX system, this setting would be 80Hz. If the THX control is set to the “On”
position, this control will not operate. An LED status indicator is provided to tell you whether
or not this control is operational – GREEN for active and RED for bypassed.

The Level control is the volume setting for the amplifier. It is used in conjunction with the
subwoofer output level control on your preamplifier or receiver. It is used to adjust the over-
all output level of your subwoofer system. If the THX control is set to the “On” position, this
control will not operate. An LED status indicator is provided to tell you whether or not this
control is operational – GREEN for active and RED for bypassed.

The KA-1000-THX is a high-performance, THX Ultra2-certified Class D digital power ampli-
fier with a built-in subwoofer crossover. It is designed specifically to drive one or two
KW-120-THX subwoofers to maximum output without audible distortion or risk of damage.
Although the amplifier’s connections and controls are simple, their use varies somewhat
according to the subwoofer system’s application. Typical setup procedures are described in
the following sections – one for digital systems and one for analog systems.

or Connectionor Connection — Today’s Dolby Digital®and
DTS®digital surround receivers and processors, as well as all THX-certified models, have
line-level subwoofer outputs and built-in subwoofer crossovers. If your system is built
around one of these, it will almost always be best to use the KA-1000-THX with the THX
switch in the “On” position. This will bypass the crossover and level controls. Connect the
subwoofer output on the receiver or processor to one or both of the KA-1000-THX’s two
input jacks (Figure 2). Use a shielded, high quality subwoofer interconnect cable of appro-
priate length with RCA plugs on each end. Your dealer can help you select a suitable cable.
Be sure to go into your receiver or processor’s speaker setup menu and set Subwoofer to
“On” or “Yes”, or if it is a THX Ultra2 certified model, select “Ultra2” in the subwoofer menu.
Your receiver or processor may have additional bass management abilities beyond simply
activating the subwoofer output. Consult your receiver or processor’s owner’s manual or
your dealer for more information on the proper bass management settings for your system.

of setup, the crossover control will not function. Its status LED will be red signifying that this
control is bypassed. Your receiver or processor will perform the crossover functions for the
subwoofer in this situation. When using either the KL-650-THX or KL-525-THX as your front
speakers, select the 80Hz (THX) crossover frequency.

Phase ControlPhase Control – In some installations the setting of the Phase control may not make much
difference, whereas in others it may be necessary to go back and forth between the Phase
and Level controls for a while in order to get the very best blend with the main speakers.
Since each control setting (including the one for crossover frequency in the receiver or
processor) affects the optimum settings for the others, it often takes a while to get every-
thing dialed in just right. Start with the Phase control at 0° and play a recording with a
prominent, repeating bass line in your listening position. Repeat this process with the
control in the 90° and 180° positions. Use the setting that yields the greatest bass output.

The Line Level input consists of a pair of gold-plated RCA phono jacks. Either one or both
may be used. (Use a shielded, high quality subwoofer interconnect cable of appropriate length
with RCA plugs on each end. Your dealer can help you select a suitable cable.) This input can
function as either a Line Level input or an LFE Input, depending on the position of the THX
On/Off switch. When THX is On, the Lowpass Crossover is bypassed and the Line Level input
effectively functions as an unfiltered LFE input.

The Line Level output consists of a pair of gold-plated RCA phono jacks. Either one or both

used to connect to a second KA-1000-THX amplifier or to connect back to your electronics if
needed.

The Speaker Level outputs are two professional style Speakon
®NL2 connections. This is a
simple connection that is easy to use, secure and foolproof. You simply align the tab on the
connector with the slot on the output jack, fully insert the connector, turn it clockwise and the
collar locks into place (Figure 1). To remove it, pull back on the collar and while holding it
back, turn it counterclockwise and pull it out. This connection is repeated on the back of the
subwoofer enclosure. If you are using two KW-120-THX subwoofers, connect the second one
in the same fashion to the KA-1000-THX’s second output jack. (A single, 20-foot length, THX
Ultra certified subwoofer speaker cable is provided with each KW-120-THX subwoofer enclo-
sure. Contact your dealer if you need a longer cable.)

The AC Line connection uses a detachable three-prong power cord. Insert the line cord into
this jack, set the Master Power switch to “Off”, then insert the power cord into an appropriate
AC receptacle. Leave the Master Power switch off until all connections are completed. (We
recommend leaving the Master Power and Auto Power switches in the “On” position for
normal operation in most systems.)
