CONNECTIONS & CONTROLS SUBSONIC FILTER The subsonic filter maximizes your Xtant amplifier’s output when a specifically tuned subwoofer system is used.

1. INPUT – Xtant3.1 and Xtant6.1 amplifiers feature RCA type input connections. Source units with an output signal level of 100mV–17V may be used.

See "Balanced Input" for proper voltage level setting.

FULLY REGULATED PWM POWER SUPPLY Xtant amplifiers feature a Fully Regulated, Pulse Width Modulated power supply. This power supply technology provides high efficiency and consistent output performance even when battery voltage is less than optimum.

CROSSOVER This control allows the user to choose the exact low-pass frequency range the amplifier will play for the best possible performance. BALANCED/FLOATING INPUT When enabled, this circuitry helps to eliminate “system noise” associated with ground loops. When combined with the input sensitivity adjustment, it allows the amplifier to accept up to 17V of input signal.

2. OUTPUT – These RCA type output connections send full range signals to additional amplifiers eliminating the need for "Y" connectors.

REMOTE LEVEL CONTROL (RLC)

The RLC or Remote Level Control allows a bass control to be adjusted remotely from the driver’s seat.

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.

OPTIONAL PERFORMANCE ENHANCEMENTS HIGH LEVEL ADAPTER (HLA)

High Level Adapters allow you to connect a source unit with speaker level outputs to your Xtant amplifier.

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:

4. GAIN – This feature is used to fine-tune the input sensitivity of the amplifier to the source unit’s output level.

PROTECTION CIRCUITRY Both Thermal and Overcurrent protection are incorporated into Xtant amplifiers. In the event of a problem, the amplifier will reduce its power to maintain operation.

STATUS LEDS (LOCATED ON THE TOP OF THE AMPLIFIER) Three LEDs indicate operational status of Xtant amplifiers. The red LED illuminates when the amplifier is “ON”, the yellow LED indicates that overcurrent protection is engaged, the orange LED indicates that the thermal protection circuit is engaged.

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 amplifier. 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.

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

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.

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.

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.

Under no circumstances should your amplifier be exposed to moisture and water.

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.

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.

9. Connect your speakers to your Xtant amplifier’s speaker terminals using 12 gauge minimum speaker cable.

• The battery ground should remain DISCONNECTED at all stages of installation.

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.

• 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.

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.

Xtant3.1/Xtant6.1 Amplifier Owner’s Manual

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)

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.

4. Leave the tone (bass/treble) controls at their usual position

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.

5. Play a CD track with wide dynamic range

OFF POSITION: defeats Subsonic Filter

6. Use the Bass Boost Control to enhance the bass performance (if desired)

ON POSITION: engages Subsonic Filter

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

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.

SOLUTION: Check connections to the amplifier’s Ground, B+ & Remote terminals. Check connection 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 operating 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.
