INPUT SENSITIVITY ADJUSTMENT
Each set of inputs (front/rear) on the 3300x are
adjustable in 10 dB steps from -20 dB to + 20 dB The five
(5) input gain settings allow the 3300x to accept input
voltages from 100 mV to 8 V. The front and rear input sensitivity 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.
CROSSOVER MODES OF OPERATION
The 3300x is equipped with independent FRONT and
REAR crossovers. Each crossover is controlled by two (2)
crossover mode jumpers labeled AMP & LINE XOVR. The
header jumper labeled AMP XOVR control the crossover
function as it applies to the 3300x’s Front (stereo) and
Rear (mono) amplifier. The modes of operation are: Position
1 = Bypass (Full Range), Position 2 = High Pass, and
Position 3 = Low Pass. (See illustration)
The two (2) header jumpers labeled LINE XOVR control
the crossover function as it applies to the 3300x’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. (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
22 4 50 Hz
13 4 70 Hz
11 4 80 Hz
10 4 90 Hz
68 3 120 Hz
56 3 150 Hz
27 3 300 Hz
15 3 500 Hz
10 3 700 Hz
68 2 1 kHz
24 2 3 kHz
18 2 4 kHz
15 2 5 kHz
The 3300x 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 position. 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 connections. 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 & MONO AMPLIFIER OUTPUT LEVELS.
ADJUST NOISE GATE THRESHOLD (IF USED):
Turn noise gate on and adjust the threshold by turning 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.
