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* Install

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*

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 Amp & Line Xovr* The head+ er jumper labeled Amp Xovr 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 Line Xovr 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*
