Xtant 4180X How to use

INPUT SENSITIVITY ADJUSTMENT
Each set of inputs (front/rear) on the 4180x are
adjustable in 10 dB steps from -20 dB to + 20 dB The five
(5) input gain settings allow the 4180x to accept input
voltages from 100 mV to 8 V. The front and rear input sen-
sitivity is adjusted independently 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. (With the installation of a
BLM-1, the input sensitivity increases to 100 mv to 17 V.)
CROSSOVER MODES OF OPERATION
The 4180x is equiped with independent FRONT and REAR
crossovers. Each crossover is controlled by two (2)
crossover mode jumpers labeled AMP & LINE XOVR. The
header jumpers labeled AMP XOVR control the crossover
function as it applies to the 4180x’s Front and Rear ampli-
fiers. The modes of operation are: Position 1 = Bypass (Full
Range), Position 2 = High Pass, and Position 3 = Low Pass.
The two (2) header jumpers labeled LINE XOVR control
the crossover function as it applies to the 4180x’s FRONT
and REAR RCA Line Outputs. The modes of operation are:
Position 1 = Bypass (Full Range), Position 2 = High Pass,
and Position 3 = Low Pass.
The High and Low Pass frequenies are determined by the
Frequency Modules (SIPs) installed in the four (4) SIP
sockets pictured on the reverse side of this document.
CROSSOVER FREQUENCY MODULES
The following is a chart of Xtant’s available frequency
modules. The frequency module (SIP) “ID Code” printed on
the SIP and the associated frequency value is detailed below.
SIP Number Frequency
224 50 Hz
134 70 Hz
114 80 Hz
104 90 Hz
683 120 Hz
563 150 Hz
273 300 Hz
153 500 Hz
103 700 Hz
752 1 kHz
242 3 kHz
182 4 kHz
152 5 kHz
The 4180x amplifier is shipped from the factory with 90
Hz High Pass and Low Pass frequency modules (SIP)
installed. To change frequency modules, simply remove
each resistor SIP and replace it with the appropriate SIP
value to achieve the desired frequency.
Low and High Pass frequencies are set independently.
Any combination of frequency modules (SIPs) may be used
(ie. 80 Hz Low Pass and 120 Hz High Pass).

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
(4) sleeved holes located on the circuit board/base assem-
bly. (see illustration)
MARK WIRES FOR TERMINATION AND REMOVE AMPLIFIER:
Determine wire lengths and mark for cutting/termination.
Remove amplifier before cutting and terminating all wires.
CAUTION: STRIPPING WIRE OVER THE CIRCUIT BOARD MAY
CAUSE PRODUCT FAILURE!
CROSSOVER SET-UP:
Adjust crossover mode jumpers at your work bench. Also,
change crossover frequency SIP’s if desired.
INPUT SENSITIVITY:
Make initial adjustment to input gain at your work bench.
To increase input gain, place jumper in the +20 dB position.
To decrease input gain, place jumper in the 0, -10, or -20
dB position. Note: factory setting is +10 dB / 300mv -1V.
MOUNT THE AMPLIFIER AND MAKE ALL CONNECTIONS:
DOUBLE CHECK ALL CONNECTIONS! TURN ON AMPLIFIER.
Check red LED, it should be on.
ADJUST FRONT AND REAR AMPLIFIER GAIN POTS.
ADJUST NOISE GATE THRESHOLD (IF USED):
The amplifier is shipped with the noise gate defeated. Turn
noise gate on and adjust the threshold by turning clockwise
to increase sensitivity (gate will open with less input sig-
nal). The green LED will illuminate when the gate passes
signal.
AFTER FINE TUNING THE SYSTEM:
Remove protective covering from amplifier and clean per the
maintanence section on page 9 of the Owner’s Manual.
Attach cover to base.
