Make sure that the electronics are not exposed to direct sunlight or strong articial light. Listening
to high sound pressure levels over a longer period of time may harm your hearing. To avoid hearing
damage do not listen to high sound levels over a longer period of time.
Placing the unit Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place it in an enclosed
position such a bookcase or cabinet that may impede the air-ow through the ventilation slots.
AC Power
(230V / 115V)
To power the unit, connect the supplied power cord to the unit and a standard AC power outlet. The unit itself
recognizes the prevailing voltage so you don‘t need to adjust it to your local voltage level. In standby mode
the amplier consumes less than 0.2W.
Connections
(Noise issues)
To ensure a safe management of the amplier and speakers, always only connect and disconnect
signal cables and speaker cables when the amplier is shut o󰀨 with the main switch on the back side.
Always use signal and speaker cables as short as possible and of good quality. Long signal cables of poor
quality works as antennas, and might in some cases create noise. Earth ground is often used to reduce noise
from electrical interference from outside the casing, however in some cases where several electrical devices
which are connected to the same grounding grid can create loops that pick up interference i.e. ground loops.
There are a couple of ways to x this problem:
• Use the same power strip / power outlet for the interfering equipment.
• Use short as possible signal cables of high quality to minimize resistance and impedance.

LINE IN
L & R
LFE & Unbalanced RCA inputs for left and right channel. Choose the left one when using LFE signal. The
left and right inputs are a sum, providing bass for both channels.
XLR BALANCED
IN
This is a balanced version of the LFE signal
XLR BALANCED
Pass Through
This works as a pass through for the XLR balanced signal, this makes it possible to connect several subs
with one signal from the source.
FREQ
This control allows you to adjust the upper limit of the subwoofer’s frequency response from 30 to 170 Hz.
The subwoofer’s output level will be reduced above the frequency this control is set 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, start with a higher
frequency (such as 100-150 Hz). With larger speakers that have greater low frequency output, you might
start with this control set lower (such as 60-100 Hz). (4th order LPF, 24dB/oct.)
PHASE This control allows you to alter the phase of the subwoofer’s output signal , 0
° - 180 ° to correct for a possible
mismatch and resulting cancellation between the subwoofer and your main speakers/amplier. To adjust,
listen to the system with music playing and tune between 0 ° and 180 ° and listen for a change in mid-bass
output. The correct position will have a higher amount of apparent mid-bass output.
GAIN This control allows you to adjust the output level of the subwoofer to match the main speakers in your system.
For most home theater receivers & surround sound processors, set the volume control to a 9 o’clock position.
For music systems, start with the volume control at a low setting and proceed slowly from there until the
levels match. The use of test tones (from a receiver/processor’s built in calibration function or test disc) and
SPL meter are suggested for proper level matching of all speakers.

Low Pass The low pass lter cuts away high frequencies at a certain point and over, the frequency point is set by the
crossover variable. We recommend that when using LFE signal to turn the low pass lter o󰀨, as most receivers
are handling lters internally.
EQ This switch allows you to choose between the three di󰀨erent EQ settings.
REF, EQ1 & EQ 2 are explained in the “EQ” section, found on page 12.
PARAMETRIC EQ
On / Off
At the “On” position the PEQ lter is active.
At the “O󰀨” position the PEQ lter is bypassed and does not inuence the signal in any way.
More info is found in the "PEQ" section, found at page 15.
PARAMETRIC EQ
Frequency
The frequency potentiometer allows the user to ne trim the frequency area that need to be tuned.
PARAMETRIC EQ
Gain
The gain potentiometer allows the user to adjust the boost or decrease of the targeted frequency.

Power
AUTO/Always ON
With this function in the “AUTO” position, your subwoofer can be safely left with the main power switch on
continuously. The subwoofer will turn itself on automatically when an audio signal is present. If no signal
is present for approximately 13 minutes, the unit will switch to standby mode (indicated by red power LED
color). While in standby mode, your subwoofer will only need minimal power. This function can be disabled
by setting this switch to the “OFF” position.
LED Indicators LED Color Function
On/Stby GREEN The unit is turned on and working normal
RED In standby mode, waiting for signal to power on.
Protect RED In protect mode*
* In the unlikely event that an over-current or over-temperature situation should occur, the Protection LED will
turn on and the amplier will be in protect mode. Turn the Amplier o󰀨 with the main power switch, and let
it rest for 10 min before you turn it back on. If the same issue occurs again, please contact XTZ personnel.
Power Switch The master power switch is located on the lower half of the unit. This rocker style switch is the main on/o󰀨
for the unit. This switch should be set to position 1 (up) for on, and 0 (down) for o󰀨. If the unit is to be left
unused for an extended period of time (e.g. when you are away on vacation), the master power switch should
be turned o󰀨, or the main power cord disconnected.
