Xtant 604X How to use

INPUT SENSITIVITY ADJUSTMENT
Each set of inputs (front/rear) on the 604x are adjustable
in 10 dB steps from -20 dB to + 20 dB The five (5) input
gain settings allow the 604x to accept input voltages from
100 mV to 8.5 V. The front and rear input sensitivity is
adjusted independently by installing a jumper across the
associated input voltage/pin location. Refer to the illustra-
tion on the reverse side of this document prior to setting
the input sensitivity.
CROSSOVER MODES OF OPERATION
The 604x is equipped with independent FRONT and REAR
crossovers. Also includes Left and Right line out
crossovers. Each crossover is controlled by four crossover
mode jumpers labeled, FRONT CHAN XOVER MODE, LINE
OUT MODE SELECT, REAR CHAN XOVER MODE, LINE OUT
MODE SELECT. The header jumper labeled FRONT CHAN
XOVER MODE controls the crossover function as it applies
to the front channels. The header jumper labeled REAR
CHAN XOVER MODE controls the crossover function as it
applies to the rear channels. (See illustration)
The two header jumpers labeled LINE OUT MODE SELECT,
control the crossover function as it applies to the front and
rear, left and right line outputs. (See illustration)
The High and Low Pass frequencies 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 the available Xtant frequency
module SIPs. The frequency module SIP’s “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
682 1 kHz
242 3 kHz
182 4 kHz
152 5 kHz
The 604x amplifier is shipped from the factory with 90
Hz High 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.
The Low and High Pass frequencies are independent. Any
combination of the available 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 assembly. (see illustration)
REMOVE AMPLIFIER AND MARK WIRES FOR TERMINATION:
Determine wire lengths and mark for cutting/termination.
Remove amplifier base before cutting and terminating
all wires.Caution: stripping wires 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. The factory setting is +10 dB / 300mv -1V. To
increase input gain, place jumper in the +20 dB posi-
tion. To decrease input gain, place jumper in the 0 or
-10 dB position.
MOUNT THE AMPLIFIER AND MAKE ALL CONNECTIONS:
Re- install the amplifier base and make all wire con-
nections. i.e. Speaker, Power, Remote, Ground, and
RCA input.
DOUBLE CHECK ALL CONNECTIONS! TURN ON AMPLIFIER.
Check red LED, it should be on.
ADJUST LEFT, RIGHT FRONT AND LEFT, RIGHT REAR AMPLIFI-
ER OUTPUT LEVELS.
ADJUST NOISE GATE THRESHOLD (IF USED):
Turn noise gate on and adjust the threshold by turn-
ing clockwise to increase sensitivity (gate will open
with less input signal). The green LED will illuminate
when the gate passes signal.
AFTER FINE TUNING THE SYSTEM:
Remove protective covering from amplifier and clean
per the maintenance section on page 9 of the Owner’s
Manual. Attach cover to base.
