Safeguards

Please take the time to read this Owners Manual.
The following guidelines are designed to assure a safe and

properly installed Xtant Mobile Audio System.

All Xtant amplifiers and accessories are intended to be installed by a certified
professional mobile audio installation specialist. It is the recommendation of
Xtant Technologies that your new Xtant product(s) and all of your mobile
audio products be installed by your Authorized Xtant Select Dealer.

Wiring Requirements

All Xtant A-Series amplifiers have minimum wire gauge requirements for:

Power - 4 gauge
Ground - 4 gauge
Speaker cables - 12 gauge.

Fusing Requirements

A Series Amplifiers are not fuse protected! For safety, an outboard fuse may be
added close to the amplifier. A fuse must be installed in-line with the power wire
at the battery, no further than 18” from battery. For fuse requirements refer to
pages 5 and 6 of this manual. In the case of a muti-amp system, use a fuse value
equal to the combined value of all (system amplifier’s) on-board power fuses.

Water and Moisture

Install all Xtant amplifiers and accessories in a location free of moisture or
exposure to water.

Standard Features

Active Resonance Control

Active Resonance Control (ARC). This patent pending circuitry compensates for
the resonance created when installing midbass or midrange speakers in the kick
panels or lower door areas of a vehicle.

Fully Regulated PWM Power Supply

All Xtant “A” Series amplifiers feature a Fully Regulated, Pulse Width Modulated
power supply. This supply technology provides high efficiency and consistent output
performance even when battery voltage is less than optimum.

Crossover

A 12dB High Pass or 24dB Mono Low Pass Crossover is variable from 40-120Hz, and
is built into the circuit board of the A2002 and A4004 amplifiers.

Balanced/Floating Input

When enabled, this circuitry helps to eliminate “system noise” associated with
“ground loops”. When combined with the input sensitivity adjustment, it allows
the amp to accept up to 17V of input signal. Balanced must be used for BTL
inputs using the HLA.

Protection Circuitry

Both Thermal and Overcurrent protection are incorporated into the “A” Series
Amplifiers. In the event of a problem, the amplifier will reduce its power to
maintain operation.

Status LEDs (Located on the top of the amplifiler)

Three LEDs, indicate operational status of all Xtant A Series amplifiers. The red LED
illuminates when the amplifier is “ON”, the yellow LED indicates that overcurrent
protection is engaged, the orange LED indicates that the thermal protection circuit
is engaged.

Optional Performance Upgrades

High Level Adapter (HLA)

This adapter allows you to connect a source unit with speaker level outputs to your
Xtant amplifier.

Connection Diagrams

1. Input – Xtant A series amplifiers feature RCA type input connections.

Source units with an output signal level of 100mV – 17V may be used.
See "Balanced Input" for proper voltage level setting.

2. Output – These RCA type output connections send full range sig-

nals to additional amplifiers eliminating the need for "Y" connectors.

3. Balanced Input – The balanced input switch serves two purpos-

es. First, it helps eliminate noises being induced into the signal path
by isolating the signal ground. Second, it is used to set the proper
input voltage range:

Off Position: 100mV – 8V
On Position: 200mV – 17V

4. Gain – This feature is used to fine-tune the input sensitivity of the

amplifier to the source unit’s output level.

5. A.R.C. – The Active Resonance Control (A.R.C.) is a level adjustment

that reduces the resonant frequencies inside the vehicle to improve the
mid-range sound quality. Turn this control either clockwise or counter
clockwise until the vocals of the music are up-front and centered in
the vehicle. The mid-range sound should be smooth and detailed.

6. Xover Switch – This switch is used to pick the preferred frequen-

cy range the amplifier will play. A high-pass, low-pass, or full range
output may be selected.

7. Xover Frequency Control – This control allows the user to

choose the exact low-pass or high-pass frequency range the ampli­fier will play for the best possible performance. The upper end of
the low-pass crossover range can be selected from 40Hz – 120Hz at
24dB per octave with a mono output. The lower end of the high­pass crossover range can be selected from 40Hz-120Hz at 12dB per
octave with a stereo output.

8. Bass Boost – This feature will add up to 12dB of low frequency

impact to the audio system. The Bass Boost is centered at 45Hz.

9. Speaker Connection – These output terminals are individu-

ally labeled for proper speaker connections. When bridging the
amplifier, use the left positive terminal and the right negative
terminal only. Warning: do not bridge the amplifier with an
impedance lower thean 4 Ohms.

10. Power Terminals – This is the main power connection for the

amplifier. The power and ground wire size should be the
same gauge.

GND – The ground wire from this connection must be attached to
bare metal on the vehicle.

REM – To turn the amplifier on/off, this terminal must be connected
to the source unit’s "remote or electric antenna" wire.

+12V – The power wire from this connection must be attached to
an inline fuse, then to the positive side of the vehicle battery.

Warning: An outboard fuse must be installed in-line with the power

wire within 18 inches of the battery.
