P REPARE FOR I NSTALLATION

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 Photon 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
out

put 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.

ot place the unit near sources of excessive moisture, such as evaporative coolers, humidifiers, etc. The power cord should be routed in such

Do n
a way that it will not be walked on, pinched or compressed in any way that could result in damaging the insulation or wire.

Inputs

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, line-level crossover or receiver with pre-amp level outputs.The SPEAKER LEVEL jacks connect directly to the
speaker outputs of any amplifier, integrated amplifier or receiver.Your amplifier section will notice no additional loading effects when you use
these inputs due to their very high impedance.

Important!!!

Do not use both LINE LEVEL and SPEAKER LEVEL connections simultaneously!

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 output level from both the main speakers and subwoofer when listening to music. A good starting point for the volume control is three
or four dots from minimum.

Warning:

Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important to verify that your receiver
Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level
adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or
distorted, and the Auto On/Off feature may not operate properly.

Low-pass Crossover - 40 to 120 Hz

All inputs sum the left and right channels together, with the resulting signal passing through an adjustable low-pass crossover before being
amplified. The crossover control allows you to adjust the upper limit of the subwoofer’s frequency response from 40 to 120 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.

A bypass switch is also provided if you wish to use an external crossover. If you are not using an external crossover, we recommend that you

use the one provided within the unit for optimum performance!

Phase Adjustment - 0°/180°

This control allows you to “reverse” the phase of the subwoofer’s output signal 180° to correct for any possible mismatch and resulting
cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with music playing. Then move
the switch from one position to the other and listen for a change in mid-bass frequency output. The correct position will have a greater
amount of apparent mid-bass frequency output.

Crossover Switch - INTERNAL X-OVER/SUBWOOFER DIRECT

This switch allows the internal crossover circuitry to be removed from the signal path. This is required in certain installations which route
the signal through external processors with a crossover circuit of their own, such as the new digital units. Simply move the switch to
SUBWOOFER DIRECT to disengage the built-in crossover. For all other installations which do not have a separate electronic
cros

sover, we recommend you leave the switch set to INTERNAL X-OVER to provide optimum performance.
