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.

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.

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

* 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.

EQ This control allows you to adjust characteristics of the subwoofer to match the room and speakers in your
system. EQ “equalization” aims to get as even frequency response as possible in your sound system.
The subwoofer has a switch marked with “EQ”, this allows you to choose between three di󰀨erent EQ
“Characteristics” settings.
Sound Adjustments (EQ, Port Tuning, PEQ)

- REF Gives a extended frequency response for the deepest bass, however the lower frequencies can
be over represented and “muddy”, depending of the room geometrics, placement of the sub and
listening position. (Reverberation)
- EQ1 Is a direct countermeasure to the “muddy” bass problem of over represented low bass/room
gain, by lowering the bass extension, the bass will be more controlled.
- EQ2 Stores more energy a bit higher in the frequency, recognized as a more punchy fast bass

The picture below shows the e󰀨ects of the di󰀨erent EQ settings. (These curves illustrates the frequency
response of a anechoic room, have in mind that the frequency response will change depending of the room
and placement of the subwoofer and listing position. E.g. A setup in a regular room with the EQ 2 could have
a total frequency response that extends much lower than represented in the graph below due to room gain.

14
Port Tuning As a part of XTZ room tuning concept, our subwoofers are often supplied with two ports and foam
plugs. By using the supplied foam plugs in the bass reex ports, you can alter the lower boundary
frequency of the subwoofer. This makes it possible to alter the sound characteristics of the subwoofer.
The picture below shows four settings:
Tuning - High freq.
With no plugs in the ports the subwoofer will provide a “quick” and “punchy” bass character. It has increased
output higher up in frequency.
Tuning - Mid freq.
If the left port is blocked and the right port is open, this will provide a bass with an increased output in the
mid region.
Tuning - Low freq.
If the right port is blocked and the left port is open, this will provide a deep bass with an increased output in
the lower frequencies.
Closed
With both ports blocked this
closed box will provide a dry
and controlled bass character.

Parametric EQ
(PEQ)
The SA-1 subwoofer amplier has a built in parametric equalizer. A parametric equalizer (PEQ) is an adjustable
lter and a very powerful tool where the user can target and compensate for issues with room modes and
nodes that are unique for every listening area. To use this function in the best way, we recommend using a
measuring equipment like the “XTZ Room Analyzer II Pro” to see how the listening area is performing. Start
by Real Time Analysis (RTA) measuring (at ear height) a couple of di󰀨erent places in your listening spot, to
see if a certain frequency range have a repeating pattern e.g. a “dip” or “peak”. Set the PEQ to On, then set
the gain to either +9 or -9 to see what frequency is targeted. Trim the frequency to the correct spot and adjust
the gain to balance out a dip or a peak.
On / Off At the “On” position the PEQ lter is active (If it does not show in the measurement, Check that the Gain
potentiometer is set to a value greater or lesser than 0dB)
At the “O󰀨” position the PEQ lter is bypassed and doest not inuence the signal in any way.

Cables - RCA
unbalanced
When installing your new subwoofer using unbalanced RCA connections, you should use high quality
shielded coaxial cables. Poor quality cables may pickup interference and result in hum or noise. Keep the
length of cable as short as possible and route all input signal cables away from power cables to reduce the
potential of induced noise.
Cables - XLR When using balanced XLR connections, be certain to use a high quality cable that maintains proper
connections to each pin, the pins are often marked with numbers. If an XLR cable that is improperly wired is
used, subwoofer performance may be degraded and you may experience increased noise and/or hum. Due
to various design di󰀨erences between di󰀨erent brands & types of equipment (e.g. di󰀨erent ground methods
for power supplies and signal reference) and long cables required in some installations, there is a potential for
any product to pickup noise via the connections and/or connected equipment (via ground loops). If you have
audible hum/buzz after completing your subwoofer connections, you may need to modify your equipment’s
cables, routing, or connection methods (power line connections and/or signal cables).
Placement While true subwoofers operate at extremely low frequencies which are primarily omni-directional, keep in mind
that frequency response and output level can be dramatically inuenced by where you place the subwoofer
within the room. Placing the subwoofer in the wrong location may degrade sound quality, limit low frequency
response and reduce maximum output level, substantially reducing your overall listening pleasure. Many
rooms often end up with non-optimal placement, depending on the size and location of the furnishings within
your room and if the possibility to reposition them exists. Finding the optimal location usually requires some
experimentation to determine what sounds best in your room, from your listening position. We suggest you
read the general guidelines below and setup the subwoofer in one of the suggested locations.
Proceed to listen to the loudspeakers multiple times, trying a few di󰀨erent locations before settling on the nal
location. To do this, perform basic setup and listen to a familiar music track or movie scene. Then move the
loudspeakers to an alternate location & repeat listening to the same music track or movie scene. If you have a
test CD and SPL meter or preferably one of our measurement systems (Room Analyzer II / II Pro), performing
a basic frequency response test can help you determine which location provides the best frequency response.

a basic frequency response test can help you determine which location provides the best frequency response.
General guidelines In most rooms, the optimum location for your subwoofer is in the closest solid front corner or somewhere
along the front wall in line with your front speaker.
This location typically o󰀨ers optimal energy coupling with the room, front-speakers and the deepest low
frequency extension, with the best high impact bass. Try to avoid location for a subwoofer that is far away
from walls or near the center of your room. When using a pair of subwoofers in stereo, it is preferable to
place each subwoofer by the satellite of the same channel, see gure below to the left. If you want a more
at frequency response and the bass evenly distributed over a larger area of listening positions, then four
subwoofers one in each corner is a terric option.
The gure below to the right shows alternative subwoofer placement options with subwoofer/- placed at
the midpoint of the wall. This can be used for one subwoofer with the subwoofer placed in the front, for two
subwoofers with the subwoofer placed at the front and back and for four subwoofers with the subwoofers
placed in the mid point of each wall.

18
Connections All connections for the subwoofer are located on the rear of the unit. Whether you choose the LFE (Low
Frequency E󰀨ects) coaxial, Left & Right coaxial or XLR-input, the subwoofer is auto selecting the one input
where there is signal.
Multiple subwoofers When connecting multiple subwoofers, it is recommended to use the XLR pass through to the next subwoofer.
The pass through is a signal split the XLR input. It is also possible to use the RCA signal connections,however
you will need to use “Y” cables (signal splitters) to route your amplier/receiver/processor output to each
woofer if it does not have multiple “SUBWOOFER” output jacks or L & R variable signal output.
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.
Always connect using the correct phase, from the plus (+) pole on the amplier to the plus (+) pole on the
loudspeaker and respectively for the minus (-) pole.
Earth ground is often used to reduce noise from electrical interference from outside the casing, however in
some cases 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.

Introduction For optimal performance, you should calibrate your system to ensure proper level matching between all speakers
and the proper setting of all controls (including crossover frequency, phase, and any channel delays your
receiver/processor may o󰀨er). This procedure will vary depending on system conguration and the information
below is provided as a basic guide to assist you. Refer to the owner’s manual for your receiver/processor for
information on performing the steps required to enter their setup mode and adjust any applicable settings.
After all connections have been made, turn on the AC power to your system, starting with the rst piece of
source equipment in the signal chain (such as a CD or DVD player), then power on any dedicated equalizer,
then power on your receiver/processor/amplier(s), and last but not least, power on the subwoofer-/s. You will
need to enter your receiver’s/processor’s setup mode and adjust any applicable speaker settings to properly
match your system conguration
Receiver/Processor

Setup & Calibration
Function
After you have veried all speakers are connected and you have measured distances of each to the listening
position, perform the auto-setup routine on your receiver/processor (if available). Many newer home theater
receivers/processors combine a measurement microphone and an automated setup routine to assist you with
proper setting of speaker levels, crossover frequency, speaker delay and phase. Consult the owner’s manual
for your receiver/processor for further instructions on how to perform the setup routine. After the auto-setup
routine is complete, verify the nal settings the receiver/processor selected to ensure there are no erroneous
settings (e.g. the settings should match your system conguration). Some settings to verify may include:
-Number of speakers (e.g. 7.1 or 5.1 system, etc.)
-Type/size of speakers (e.g. small or large front/surround and subwoofer set to yes/on)
-Crossover point should be similar for identical speakers (e.g. if your system using 3 of the same speak-
ers for all front channels, verify the receiver/processor selected the same crossover point for all these
channels)
-Crossover frequency should be selected. We recommend 80Hz for the satellite speakers to start with.
Higher or lower crossover point may yield better results in your system depending on your speaker
setup
-Note: some receivers do not have an adjustable frequency, instead there is only a choice of “small” or
“large”. In this case, we recommend choosing “small”.
-Gain settings for each channel should be reasonably close (e.g. if the speakers are placed at even
distances, the gain setting for each channel should typically be within a couple dB from channel to
channel). If the receiver/processor gain trim setting for the subwoofer channel is a large value (e.g. +12
or -12dB) you may need to increase or decrease the subwoofer’s volume to achieve a better match.
