SAFEGUARDS  
Please take the time to read this Owners Manual.  
The following guidelines are designed to assure a safe and  
properly installed Xtant Mobile Audio System.  
All Xtant amplifiers and accessories are intended to be installed by a 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 Select Dealer.  
In st a l l e r s Re f e r e n c e (in se r t )  
The Installers Reference is an insert included in this manual. It is designed to  
assist your Authorized Xtant Select Dealer ’s professional installer.  
Installation techniques critical to the creation of a high-performance mobile  
audio sound system, (procedures for running wires, basic safety rules, and  
system layout concepts) are not presented in this owners manual. All  
Authorized Xtant Select Dealers have been chosen for their expertise in sys-  
tem design and advanced installation capabilities and Xtant highly recom-  
mends that you have all of your mobile audio products professionally  
installed. If, however, you choose to install your Xtant amplifier yourself,  
please refer to the Installers Reference prior to installation.  
Wir in g Re q u ir e m e n t s  
All Xtant amplifiers have minimum wire gauge requirements for Power,  
Ground, Remote Turn-On, and Speaker cables. Please refer to the Installers  
Reference for recommended wire gauges.  
Fu sin g Re q u ir e m e n t s  
The 603X is not fuse protected! For safety, an outboard 100 amp fuse may be  
added close to the amplifier. A 100 amp fuse must be installed in-line with the  
power wire at the battery. In the case of a multi-amp system, use a fuse value  
equal to the combined total demand of all amplifiers in the system.  
Wa t e r a n d M o ist u r e  
Install all Xtant amplifiers and accessories in a location free of moisture or  
exposure to water.

The 603x is a “true” three (3) channel amplifier which com-  
bines unique performance features with outstanding design  
flexibility to provide a single chassis “system solution” for  
most mobile audio applications. With its on-board crossover, a  
high performance, bi-amplified system is easily configured.  
By utilizing the on-board crossovers four (4) RCA line outputs, you can steer  
specific frequency ranges to additional amplifiers, thus eliminating the need  
for external, active crossover components.  
As with all Xtant “x” Series amplifiers, the 603x incorporates an on-board  
noise gate, forced convection thermal management system, and a Pulse Width  
Modulated power supply for high efficiency and unsurpassed reliability. All  
these features are encased in Xtants exclusive finish of stainless steel and  
copper!  
St a n d a r d Fe a t u r e s  
Fo r c ed Co n v ec t io n Co o l in g : All Xtant “x” Series  
amplifiers employ forced convection cooling for thermal man-  
agement. An on-board thermal sensing circuit regulates fan  
speed to maintain optimum operating temperature.  
PWM Po w er Su ppl y : All Xtant “x” Series amplifiers feature  
a fully regulated, Pulse Width Modulated power supply. This sup-  
ply technology provides high efficiency and consistent output performance even  
when battery voltage is less than optimum.  
Cr o sso v er : 12 dB (Butterworth)/ 24dB (Linkwitz-Reily) filter network with  
selectable Bypass (Full Range), High Pass, or Low Pass modes of operation.  
Frequency selection is via a 12 pin Frequency Module (SIP). The amplifier is  
shipped with a 90 Hz SIP installed, 13 other frequencies are available from your  
Xtant Dealer. Refer to page 7 of this manual for a list of the available frequencies.  
N o ise Ga t e: Provides deep muting when no musical signal is present. Features  
include adjustable threshold and bypass switch.  
Ba l a n c ed / Fl o a t in g In pu t : The 603x offers a built on board balanced  
input stage. When placed in the enable position this circuitry helps to eliminate  
“system noise” associated with “ground-loops”. Additionally the balanced input  
allows the 603x to accept input voltage from 100mV to 17V.  
M o d u l a r Ex pa n sio n Po r t : All Xtant amplifiers are supplied with a mod-  
ular port used for docking any of Xtants signal processing modules.  
Pr o t ec t io n Cir c u it r y : Both Thermal and Overcurrent protection has been  
incorporated into all Xtant amplifiers. In the event of a problem, the amplifier will  
reduce its power to maintain operation.  
St a t u s LEDs: Four LEDs, visible through the cover, indicate operational status  
of all Xtant amplifiers. The red LED illuminates when the amplifier is “ON”, the  
green LED indicates when the noise gate is open, the yellow LED indicates that  
overcurrent protection is employed and the orange LED indicates that the ther-  
mal protection circuit is operational.

O N -BO ARD ELECTRO N IC CRO SSO VER  
All Xtant “x”, and “ix” Series 2 channel amplifiers have on-  
board, two-way electronic crossovers. Xtant 3 and 4 channel models feature  
two independent two-way crossovers. Each crossover is tied to a set of inputs  
and controls the frequency range of the associated amplifier. Independent fre-  
quency selection is provided for both the High and Low Pass sections. A set  
of selectable RCA line outputs (to feed additional components) are included  
with each crossover. In addition, each crossover features two on-board head-  
er jumpers (one for the amplifier and one for the RCA line outputs) which  
allow you to select Bypass (Full Range), High Pass, and/ or Low Pass modes.  
The “ix” Series models offer an additional Band Pass selection. When chosen,  
the Band Pass selection is available via the Low Pass jumper position for the  
RCA line outputs.  
The following Frequency Modules (SIPs)* are available from your Xtant  
Dealer: 50 Hz, 70 Hz, 80 Hz, 90 Hz, 120 Hz, 150 Hz, 300 Hz, 500 Hz, 700 Hz,  
1 kHz, 3 kHz, 4 kHz, and 5 kHz.  
Please refer to the Installers Reference (insert) for the Frequency Module recep-  
tacle location and chart of frequency/ SIP value code numbers  
* SIP: an acronym referring to multiple resistors in a Single In-Line Package

O P TIO N AL ACCESSO RY M O DULES  
Xtant optional accessory modules are easily and quickly  
installable by your Authorized Xtant Dealer. The upgrade mod-  
ules snap into place on the amplifiers PC board when the top of the unit is  
removed. These accessories enhance your entire system, expanding and cus-  
tomizing performance for your unique applications.  
PARAM ETRIC EQ UALIZATIO N M ODULE – PQ M 1  
The PQM-1 is a precision tuning instrument, designed to be  
adjusted with the use of a Real-Time-Analyzer. This true,  
fully adjustable, one band parametric equalizer provides  
individual frequency, Q/ bandwidth, and +/ - 18dB gain adjust-  
ment controls. By utilizing one of three (3) frequency modules included, any  
frequency from 20 Hz to 20kHz can be chosen. The “Q” ranges from 1 to 10  
in value, allowing a wide variety of bandwidth adjustment to address the  
subtle tuning requirements common to mobile audio systems. All 2-channel  
Xtant amplifiers can accept one PQM-1. All 3/ 4-channel amplifiers will  
accept two PQM-1 modules if desired (one PQM-1 per 2 channels of input).  
BASS BO O ST M ODULE-LFQ 45  
The LFQ 45 is designed to add, 4, 8, or 12 dB of Bass Boost to any  
sound system powered by an Xtant amplifier(s).  
The LFQ 45 will enhance the bass performance of any sub-  
woofer system, sealed or ported. However, if you are using the LFQ 45 with  
a ported enclosure, be sure that the 45 Hz center frequency is at or above the  
vent tuning frequency or damage may occur to the speaker.

A.  
The internal fan in all Xtant amplifiers need periodic cleaning.  
If you are in a high dust environment, every 30 days is  
recommended. We recommend that your dealer remove  
the cover and clean the fan blades with a soft brush. Loose  
dust can be removed with a vacuum hose.  
Ca u t io n :  
Have your dealer check the fan for obstructions if your  
amplifier over heats. When the Thermal Protection Circuit  
is engaged, the orange LED will be illuminated and power  
may be reduced.  
B.  
Have your dealer check the circuit board for dust. If  
present, use a low pressure air source to blow-off the dust  
particles. DO NOT use a high-pressure source, brush or  
any similar device to clean the circuit board!  
Cl e a n in g t h e Am p l if ie r  
A.  
Clean the stainless steel cover with a light dust cloth. For a  
more thorough cleaning, use window cleaner that is  
ammonia free. Apply the cleaner to the cloth (not the  
amplifier) and wipe the surface. Take care not to catch the  
cloth on the copper mesh.  
Ca u t io n :  
B.  
Do not allow liquids to touch the circuit board.  
To polish the stainless steel cover use a commercially  
available stainless steel cleaner/ polish. It is important to  
note that stainless steel has a (directional) grain. Please  
read the directions supplied with the polish before  
beginning. As a rule of thumb, always polish with the  
grain. Apply the cleaner/ polish to the cloth (not the  
amplifier) and wipe the surface. Take care not to catch the  
cloth on the copper mesh.
