Input Sensitivity Adjustment
The X%(' offers five ()) input gain settings* The adjustment runs in $( dB steps from
+!( dB to . !( dB* This wide range of adjustment allows the X%(' to accept input
voltages from $(( mV to $# V* Adjustment is made by installing a jumper across the
associated input voltage/pin location* Refer to the illustration on the reverse side of
this document prior to setting the input sensitivity*
Crossover Modes of Operation
The X%(' is equipped with independent Front and Rear crossovers* Each crossover is
controlled by two (!) crossover mode jumpers labeled
AAmpp & Liine XXovvr
* The head+
er jumper labeled
AAmpp XXovvr
control the crossover function as it applies to the X%('’s
Front (stereo) and Rear (mono) amplifier* The modes of operation are: Position $ /
Bypass (Full Range), Position ! / High Pass, and Position ' / Low Pass and Position
"/Band Pass* (See insert)
The two (!) header jumpers labeled
Liine XXovvr
control the crossover function as it applies
to the X%('’s Front and Rear RCA Line Outputs* The modes of operation are: Position $ /
Bypass (Full Range), Position ! / High Pass, and Position ' / Low Pass* (See insert)
The High and Low Pass frequencies are determined by the Frequency Modules (SIPs)
installed in the eight (-) SIP sockets pictured on the insert*
Crossover Frequencies & SIP’s
The following is a chart of Xtant’s available frequencies* The frequency SIP “ID Code”
printed on the SIP and the associated frequency value is detailed below*

The X%(' is shipped from the factory with &( Hz HiPass and LowPass frequency SIP’s
installed* To change a frequency, simply remove the resistor SIP and replace it with
the appropriate SIP value to achieve the desired frequency*
The Low and High Pass frequencies are independent* Any combination of the available
frequency SIP’s may be used*

Installation Instructions
This document has been crafted to make installation, system design and trouble+
shooting, a quick and easy process*
Installation Sequence
Remove Amplifier Cover:
Loosen allen head screws and lift+off cover* Do not remove protective
covering on stainless steel lid until installation is complete*
Temporarily Mount Amplifier:
The amplifier is designed to be anchored through the four (") holes located on the
circuit board/base assembly*
Mark Wires for Termination and Remove X%(':
Determine wire lengths for Power, Ground, Remote, & speaker cables* Mark for
cutting/termination* Remove X%(' before cutting and terminating all wires*
CAUTION:
stripping wires over the circuit board will cause product failure*
Crossover Set+up:
Adjust crossover mode jumpers at your work bench* Also, change crossover frequency
SIP’s if desired* Refer to crossover modes of operation on opposite page*
Input Sensitivity:
Make initial adjustment to input gain at your work bench* To increase input gain, place
jumper in the .!( dB position* To decrease input gain, place jumper in the (, +$(, or +!( dB
position* Refer to Input Sensitivity Adjustment on back panel for more information*
Mount the Amplifier and make all connections:
NOTE:
Place service jumper in off position before making any connections*
Ins
tall
the amplifier and make all wire connections* i*e: Speaker, Power, Remote, Ground,
and RCA input*
Double Check All Connections! Turn On Amplifier*
Place service jumper in the on position, check red LED, it should be on*
Adjust Left and Right Front as well as Rear Amplifier Output Levels*
Adjust Noise Gate Threshold (if used)
Turn noise gate on and adjust the threshold by turning clockwise to increase sensi+
tivity* The green LED will illuminate*
After Fine Tuning the System:
Remove protective covering from amplifier and clean per the maintanence section
on page & of the
Owner’s Manual*
Attach cover to base*
