Prepare for Installation
Your new Chrysalis subwoofer provides for a number of installation options. Read all the installation information below in order to
determine which installation option is best for your system. Remember to perform all installation procedures with system power turned
off to prevent possible damage.

Placement
The first step in installing your new BassMatrix is to determine where it will be placed in the room. Unpack the system carefully and use the
following guidelines in order to find the best room placement option.
True subwoofers operate at extremely low frequencies which are primarily omni-directional. Keep in mind that frequency response and
output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. To obtain optimum
output from your subwoofer, place it within a foot of a corner. This location will offer the greatest output levels and optimum low frequency
extension. If at all possible, your subwoofer should be placed along a wall. The worst location for a subwoofer is typically far away from any
walls and close to the center of your room. Avoid these locations when possible. When using a pair of Chrysalis subwoofers in stereo, it is
preferable to place each subwoofer near the satellite of the same channel.
Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location within your
environment will likely require some experimentation. We suggest you experiment with the location during setup to find what sounds best to
you when seated in your typical listening position.
Regardless of where you install your Chrysalis subwoofer, it must remain in an upright position (woofer facing forward). Using, shipping or
storing the subwoofer in any other position for an extended period of time may result in damage to the unit not covered by warranty.
Caution!
This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc.
Do not place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such
a waythat it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire.
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a
pre-amp, signal processor (such as LFE out), line-level crossover, or receiver with pre-amp level outputs. When using the line level jacks, some
receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the
subwoofer to produce less output than it is capable of.

Figure 1. BassMatrix Rear Panel Connections
Figure 1 shows the connections on the rear panel of the BassMatrix.
Following are brief descriptions of the connections described in Figure 1. More detail on these connections can be found on the next page.
(1) LOW-PASS CROSSOVER
Use this knob to select the high-frequency range at which you wish to cut off the signal to the subwoofer. When the knob is turned all the
way to the left (counter-clockwise), the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 200 Hz.
(2) VOLUME Control
This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to
achieve similar volume level from between both the main speakers and subwoofer. When pressing volume up or down, the speed at which
the power light blinks indicates subwoofer volume - the faster the blinking, the louder the unit plays. After the volume blinking stops,
the unit will blink out the actual volume number. Slower blinks represent tens, and faster blinks represent ones. So, for example, if the
volume were set at 34, after the rapid blinking stopped you would observe three slow blinks followed by four faster blinks, indicating a
volume of 34.
Note: Volume is also controllable by using the supplied remote, when defaults are restored. The default is 30 out of 100.

(3) AUTO ON/OFF Switch
Use this switch to select between auto-on (active) and constant on (inactive) operation.
(4) LINE OUTPUT
Connect these jacks to the LINE IN of the power amp or receiver input to use the BassMatrix internal high pass crossover. See below for
amore detailed explanation of this crossover.
(5) LINE INPUT/LFE Input
Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks of your receiver/processor. If using the
LFE output from your receiver or processor, plug the single cable into the “L” – LFE input or, for more signal, use a“Y” connector (not
included) and feed the signal into both“R” and“L” inputs.
(6) HIGH PASS CROSSOVER Switch
This switch selects the frequency for the high pass crossover. This crossover is functional on both line and speaker-level outputs. Smaller
speakers with limited low frequency output may perform better using the higher 100 Hz setting that will reduce the low frequencies sent
to them. Larger speakers with greater low frequency output may be able to handle the 80 Hz setting without strain.
(7) SPEAKER LEVEL INPUT Terminals
Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection,
when yougo to the receiver speaker set up menu, make sure you select the large speaker option
(8) SPEAKER LEVEL OUTPUT Terminals
Sends a crossed-over speaker-level signal to the front speakers. See below for a more detailed explanation of this crossover.
Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type “INPUT” jacks when connecting
your subwoofer to a pre-amp, signal processor, or line-level crossover. The“SPEAKER LEVEL INPUT” jacks connect directly to the speaker
outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs
because of their high impedance.
Note:
Do not use both the RCA/Phono “INPUT” connections and “SPEAKER LEVEL INPUT” connections simultaneously.
Low-Pass Crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before
beingamplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 60 to 150 Hz. The
subwoofer’s response will begin rolling off above the frequency you set this control to.
You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system.
If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120 Hz)
than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set
lower, such as 80 Hz.

Subwoofer Direct
Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 200 Hz into the subwoofer. See below for a
more detailed explanation of this feature.
Speaker Level Output/Line Level Output
When connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes the lower bass from your satellites,
enabling them to do a better job reproducing high frequencies and giving your receiver’s amp more headroom (up to 50% more power).
You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish to bypass this crossover.
Caution!!!
To avoid damage to your main amplifier, be sure to maintain correct polarity when making all connections. Red (positive) to red, and black
(negative) to black. Be sure that all connections are tight, and that there are no loose strands or frayed wires.
Power Switch
The master power switch is located on the lower right half of the unit. This rocker style switch is the main on/off for the unit. This switch
should be set to position 1 for on (up), 0 for off (down).
A Word About Your Receiver’s Crossover and the BassMatrix Crossover
Your Chryslais BassMatrix subwoofer is designed to operate using the full range audio signal for input when using the built-in crossover
(controlled by the dial on the back panel). Many home theater processors/receivers (Dolby Digital®, DTS®, THX®) have a“subwoofer out”
jack that performs this same function and are designed to be used with a powered subwoofer.
In these installations, you may want to bypass the crossover in either the processor or the Chrysalis subwoofer. In some cases, you may want
to use BOTH crossovers. To do this, you can use both your processor’s crossover and the one internal to the Chrysalis sub. You should
stagger the frequencies (i.e., 120 Hz subwoofer, 80 Hz processor) for best results.
To bypass the subwoofer’s internal crossover when the unit is being fed a low pass signal from another crossover, simply locate the knob
marked “LOW-PASS CROSSOVER” on the rear panel of the subwoofer and turn it counterclockwise to the“DIRECT” position. This will
eliminate the internal crossover from the signal path.
Note:
When not using an external crossover, you should use the built-in crossover for optimal performance. When using a single RCA sub out from
the processor, it does not matter which line level input (L/R) is used.

INTERCONNECT CABLES
When installing your new Chrysalis subwoofer using the line-level connections, you should always use shielded phono cables. There are many
decent cables available today, most any of which will work perfectly well. We do recommend that you keep the length of cable as short as
possible to avoid any potential noise problems.
When using speaker level connections, use a quality speaker cable that mates well with the connectors (at least 14-gauge). Be very careful to
avoid any loose or frayed strands that could result in a short, causing a dangerous condition and possible damage to your unit. Cables of
extremely large size are typically not required. Extremely large gauge wire may not properly fit in the binding posts, resulting in a poor
connection and possible short circuits.
Placement
True subwoofers operate at extremely low frequencies, which are primarily omni-directional. While it is recommended that the subwoofers be
placed on the same plane as the satellite speakers, room and system conditions often dictate otherwise. Keep in mind that frequency response
and output level can be drastically influenced by placement, depending on the acoustic properties of your listening room. Typically, the
optimum location for a subwoofer is in a front corner of your listening room. This location will usually offer the greatest output levels and
optimum low frequency extension. The worst location for a subwoofer is typically far away from any walls, close to the center of your room
andnear an opening or door way. Avoid these locations when possible. When using a pair of Chrysalis subwoofers in stereo, it is preferable to
place each subwoofer near the satellite of the same channel. Typically, a minimum distance of 1 to 2 feet from your TV to the subwoofer will
be adequate to avoid any magnetic interference.
Caution!
This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc.
Do not place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc.The power cord should be routed in such
away that it will not be walked on, pinched, or compressed in any way that could result in damaging the insulation or wire.
