CONNECTIONS & CONTROLS
1. INPUT – Xtant3.1 and Xtant6.1 amplifiers feature RCA type input connec-
tions. Source units with an output signal level of 100mV–17V may be used.
See "Balanced Input" for proper voltage level setting.
2. OUTPUT – These RCA type output connections send full range signals to
additional amplifiers eliminating the need for "Y" connectors.
3. BALANCED INPUT – The balanced input switch serves two purposes. First,
it helps eliminate noises being induced into the signal path by isolating the signal ground. Second, it is used to set the proper input voltage range:
OFF POSITION: 100mV – 8V ON POSITION: 200mV – 17V
4. GAIN – This feature is used to fine-tune the input sensitivity of the
amplifier to the source unit’s output level.
5. XOVER FREQUENCY CONTROL – This control allows the user to choose
the exact low-pass frequency range the amplifier will play for the best possible
performance. The upper end of the crossover frequencies can be selected from
40Hz–120Hz at 24dB per octave.
6. BASS BOOST – This feature will add up to 12dB of low frequency impact
to the audio system. The Bass Boost is centered at 45Hz.
7. SUBSONIC – This feature limits the lower end of the low-pass frequencies
sent to the subwoofers. The subsonic feature includes a selectable on/off
switch, and a control knob used to adjust the lower end of the low-pass range.
The subsonic setting can be selected from 20Hz-80Hz at 24dB per octave.
8. RLC – This port allows the use of the optional Xtant “remote level control”
(RLC). The RLC is a bass control module that can be installed in any location
within the vehicle for remote adjustments.
9. SPEAKER CONNECTION – Two sets of speaker terminals are provided for
dual woofer applications. When connecting a single woofer, use only one set of
speaker terminals.
WARNING: Xtant3.1 and Xtant6.1 amplifiers are not bridgeable.
10. POWER TERMINALS – This is the main power connection for the ampli-
fier. The power and ground wire size should be the same gauge.
GND – The ground wire from this connection must be attached
to bare metal on the vehicle.
REM – To turn the amplifier on/off, this terminal must be connected
to the source unit’s "remote or electric antenna" wire.
+12V – The power wire from this connection must be attached
to an inline fuse, then to the positive side of the vehicle battery.
WARNING: An outboard fuse must be installed in-line with the power wire within
18 inches of the battery.

SAFEGUARDS
All Xtant amplifiers and accessories are intended to be installed by an Xtant-certified professional
mobile audio installation specialist. It is the recommendation of Xtant Technologies that your
new Xtant product(s) and all of your mobile audio products be installed by your Authorized
Xtant retailer.
In the event you decide to install your new Xtant product(s), please take the time to read this
Owner’s Manual in its entirety. Installation and/or use of your amplifier in applications or methods
other than those specified in your Xtant amplifier owner’s manual may result in a reduction of the
overall performance capability of the amplifier. Any such installation or usage renders the product warranty void. The following guidelines are designed to assure a safe and properly installed
Xtant Mobile Audio System.
WIRING REQUIREMENTS
Your Xtant power amplifier is designed for use with a 12 Volt, negative ground system. Installation
of your Xtant amplifier in a vehicle with a POSITIVE ground system will result in severe damage to
the amplifier, other audio components and/or the vehicle’s electrical components. If your vehicle
uses a positive ground system, please consult your authorized Xtant retailer or specialty install shop.
Xtant3.1 and Xtant6.1 amplifiers have minimum wire gauge requirements for:
Power - 4 gauge Ground - 4 gauge Speaker cables - 12 gauge
FUSING REQUIREMENTS
Xtant3.1 and Xtant6.1 amplifiers are not fuse protected! A fuse must be installed in-line with
the power wire at the battery, no further than 18" from battery. For safety, an outboard fuse
should be added close to the amplifier. For fuse requirements for a single amplifier, refer to page
3 of this manual. In the case of a multi-amp system, use a fuse value equal to the combined
value of all system amplifier’s power fuses.
LOCATION
A firm, flat surface with minimum vibration is ideal. Your Xtant amplifier may be mounted
horizontally or vertically on a flat surface. The amplifier should NEVER be mounted upside
down. This ill-advised configuration can increase internal operating temperatures, decrease the
amplifier’s ability to dissipate heat and speed up the amplifier’s automatic thermal shut down
mechanism.
Under no circumstances should your amplifier be exposed to moisture and water.
To ensure adequate ventilation, the ideal location for your Xtant amplifier is an area away from
any heat source, with at least 2 inches of clearance above and around the amplifier.
COMMON OVERSIGHTS
• The battery ground should remain DISCONNECTED at all stages of installation.
• Do not begin drilling until you have put your Xtant amplifier aside. Using the amplifier as a drilling
guide may cause irreparable damage to the amplifier and void your warranty.
• Do not route any wires underneath or outside the vehicle body.
• Route signal wires (RCAs from source unit, speaker wires, etc.) away from power wires (power,
ground, etc.) to avoid ground loops and other sources of noise.
INSTALLATION
Any deviation from the connection specifications recommended may cause serious damage to
the amplifier, speakers and/or vehicle electrical system. Please double-check the connections
before turning the system on.
PROCEDURE
1. Disconnect the vehicle’s negative battery connection.
2. Using the supplied allen wrenches, remove the four (4) screws from the annealed stainless steel
amplifier cover. Put this aside until your installation is complete to prevent damage to the cover.
3. Place your Xtant amplifier at the predetermined mounting location. Using a felt pen, mark
the exact position of the mounting holes on the mounting surface. Set your Xtant amplifier
aside. Use a sharp, precise blade to cut small circles in the carpet and padding around the
four marks denoting your mounting holes to expose the metal underneath. Use a center
punch to make an indentation in the metal to ensure that you drill the exact position for the
screws. Drill the four holes as marked.
4. Temporarily mount your Xtant amplifier using the four (4) long screws provided.
5. Run a power cable from the vehicle’s battery through the firewall and through the interior of
the vehicle connecting one end to your Xtant amplifier’s B+ terminal and connecting the
other end to the positive post on the battery.
NOTE: Install a circuit breaker/fuse within 18" of the battery. This effectively lowers the risk of
severe damage to your vehicle should a short circuit ever occur in the audio system. Do not install
the fuse in the fuse holder until all installation steps have been completed.
6. Find a good ground spot on the vehicle’s chassis and remove the paint to reveal bare metal at
the contact point. Attach the ground wire to that contact point and connect the other end of
the ground wire to the GND terminal of your Xtant amplifier.
7. Connect a Remote Turn-on wire from your source unit to your Xtant amplifier’s REM terminal
(14 or 16 gauge wire). If your source unit does not have a dedicated Remote Turn-on lead,
you may connect to the source unit’s Power Antenna lead.
8. Connect RCA cables from your source unit to your Xtant amplifier’s RCA input jacks. If RCA
(low) level output is not available, use Xtant’s High Level Adapters (HLA—not included) to
connect the speaker level (high level) wires to a set of RCA cables.
9. Connect your speakers to your Xtant amplifier’s speaker terminals using 12 gauge minimum
speaker cable.
10. If you are using the RLC remote level control, mount the control in a convenient location in the
driver’s area and route the wire and connect to your Xtant amplifier’s RLC port.
11. Double-check all the previous installation steps, in particular, the wiring and component connections. Securely mount the amplifier. Remove the protective film and screw the annealed
stainless steel cover back onto the amplifier.
12. If everything is in order, reconnect the vehicle’s negative battery connection and begin
adjusting your amplifier.
NOTE: Be sure that the Gain Level on the amplifier is turned all the
way down (counter clockwise) before proceeding with adjustments.

ADJUSTMENTS
CROSSOVER FREQUENCY SELECTION
Your Xtant amplifier has a built-in low-pass filter offering continuously
adjustable crossover frequencies between 40-120Hz Hz. Adjust the setting
according to your speaker component specification or to your particular
preference—counter-clockwise for a lower frequency, clockwise for a higher
frequency.
BALANCED INPUT ADJUSTMENT
OFF POSITION: when using Low Level (RCAs) without a Line Driver
(100mV-7.5V)
ON POSITION: when using High Level (speaker) inputs with Xtant High
Level Adapters (HLA) or Low Level (RCAs) with a Line Driver (7.5V-17V)
GAIN CONTROL ADJUSTMENT
1. Turn the Gain control all the way down (counter-clockwise)
2. Set the volume control of the source unit to approximately
2
⁄3
of its maximum output
3. Turn the balance control of the source unit to its center position
4. Leave the tone (bass/treble) controls at their usual position
5. Play a CD track with wide dynamic range
6. Use the Bass Boost Control to enhance the bass performance (if desired)
7. To locate the optimum input sensitivity setting, turn the Gain control clockwise until audible
distortion starts to develop. Turn the sensitivity control counter-clockwise slightly to minimize the
distortion.
8. If you often switch between sources (CD, tape, radio, etc.) you will need further adjustment
since radio output level differs from that of CD or tape. In this case, you need to locate a balanced
sensitivity setting which is best for the output level of your sources.
BASS BOOST CONTROL ADJUSTMENT
Select a boost level between 0dB and +12dB to enhance the bass performance for your sound system. Remember that every 3dB of boost costs you
twice as much in power. Make sure to set the final gains after setting the
Bass Boost to work best with your subwoofer/enclosure combination.
RLC PORT
If you are using the RLC control, make sure to take this into account during
set-up procedures. Set-up the system with the RLC plugged in and with the
level knob turned all the way up (clockwise). Adjust according to taste and to
work best with your subwoofer system.
SUBSONIC FREQUENCY SELECTION
The subsonic filter maximizes your Xtant amplifier’s output when a specifically tuned subwoofer system is used. For example, if your subwoofer system is designed to play 40Hz-80Hz only, setting the Subsonic Filter to 40Hz
will prevent the amplifier from wasting power trying to reproduce signals
below 40Hz. The subsonic frequency settings are continuously adjustable
from 20Hz-80Hz. Select the setting according to your preferred subwoofer
system specification or to your particular preference.
OFF POSITION: defeats Subsonic Filter
ON POSITION: engages Subsonic Filter

TROUBLESHOOTING
SYMPTOM: No power
SOLUTION: Check connections to the amplifier’s Ground, B+ & Remote terminals. Check con-
nection at “+” terminal of the battery. Check the remote turn-on terminal. Ensure it receives
power when the source is turned on (or when the switch is turned on). Refer to the Installation
Section. Check the power line fuse: if fuse is blown, replace it; if fuse continues to blow, check
the power wire and also the amplifier for a short. If the short is in the power wire, fix it; if the
short is in the amplifier itself, see your Xtant dealer.
Check the voltage at the amplifier, and the remote ON/OFF lead. The voltage should measure
between 11 V - 15 V. If the measurement is beyond this range, have the source unit checked out
by an authorized dealer.
SYMPTOM: Power without sound with red power indicator on
SOLUTION: Turn the amplifier off, and Check all input & output signal cables and connections.
Check the speakers for short with a VOM (volt meter) or by connecting them to another audio
system. After making sure everything is normal, turn the amplifier on again.
SYMPTOM: Power without sound with orange protection indicator on
SOLUTION: The continuous orange light of the protection indicator signals a high internal oper-
ating temperature, which results in the amplifier switching off temporarily; when the amplifier
cools down to a safe level, the amp will automatically restart.
SYMPTOM: Very low sound from both radio & other source
SOLUTION: Check your radio’s fader control. Check the amplifier’s Input Sensitivity Level.
SYMPTOM: Frequent automatic amplifier shut down
SOLUTION: This indicates that the amplifier is operating continually at an exceedingly high
internal temperature. High operating temperature caused by inadequate ventilation: Refer to the
sub-section titled LOCATION for better amplifier location.
High operating temperature caused by an excessively low impedance load, say below 2 ohms
stereo or 4 ohms bridged: Check for bad speakers and/or electronic crossover, proper passive
crossover components; if difficulty persists, please consult your local authorized Xtant retailer.
High operating temperature can be caused by an incorrect input sensitivity level: refer to subsection titled GAIN CONTROL ADJUSTMENTS for correct setting.
SYMPTOM: “Motorboating”: The amplifier power indicator going off repeatedly when the
audio system is on
SOLUTION: Check the amplifier’s connection to the battery.
Check battery voltage. If low, recharge or replace battery. Check all ground connections.
