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 Installer’s 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 Installer’s 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 Installer’s
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 crossover’s 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 Xtant’s 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 Xtant’s 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 Installer’s 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.

Cl e a n i n g t h e f a n / Ci r c u i t Bo a r d
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.
