— 1. INTRODUCTION
1) Strong Power Supply
The APA2160 uses a high performance
MOS-FET and a strong power supply
circuit with a DC-DC converter, high
capacity low impedance capacitors, and a
gapped E core choke coil. This makes for
an extremely stable supply for power
despite the harsh power fluctuations and
environmental changes particular to cars
and clear sound.
2) Designed for high sound quality
A low-noise operation amplifier and layered
film capacitors reproduce the energetic low
bass and clear, undistorted sound provided
by such digital sources as Compact Discs
and DVD.
3) Low distortion and wide output range.
The APA2160 offers stable playback with
high output simultaneously from the 2
channels and low distortion even beyond
the range of frequencies audible to the
human ear.
4) Output Mode Selector
An output mode selector switch provides the
following high output(rated):
* STEREO mode---80W x 2
- MONO mode---250W x 1
5) High pass/Low pass variable electronic
crossovers
The APA2160 incorporates a selectable
High Pass or Low Pass electronic
crossover for all 2 channels. In both cases,
the crossover point it fully adjustable
between 55 Hz to 550 Hz and features a
-12dB per octave roll off. The frequency
range changeover switch enabled it to
switch to 550 Hz to 5,500 Hz high region
range and effective for tweeter connection.
6) Bass extender circuitry
Adding “boost” to low frequency sound
information make it able to perform
frequency compensation according to the
system, produces well-balanced output.
7) Protection circuit.
A protection circuit is used to constantly
protect against damage to the amplifier
from loads, short-circuits, overcurrents,
overheating, etc.

This Clarion Amplifier Designed for On-road Vehicle (DC 12V) Purpose.
This section lists mounting and wiring precautions for installing the Clarion APA2160 car audio
amplifier. Combined with the experience of a professional installer, these safeguards are sufficiently
detailed to successfully complete installation. If you do not have the necessary skills, do not install
the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations.
and connection.
Mounting Precaution
= Although this Clarion amplifier incorporates a large heat sink and protection circuits, mounting
any amplifier in a confined space without any air movement can still damage internal circuits over
time. Choose a site that provides adequate ventilation around the amplifier. For easy system set-
Up, mount the amplifier so the controls and fuse will be accessible after installation.
: When you attach this product, please choose the place distant as much as possible from the
Antenna of vehicles. When it attaches near the antenna of vehicles, a noise may occur.
In Addition, Observe These Precautions:
" For the most efficient cooling, mount the amplifier so cool air runs along the length of the
heatsink. Remember, any moving air will dissipate heat.
= Mount the amplifier on a rigid surface. Do not install the amplifier on plastic or other combustible
material.
= Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines,
brake lines (under chassis), or electrical wiring.
Wiring Precautions
- Read all wiring precautions. If you are not sure of the connections, contact your authorized
Clarion dealer.
= Before installation, make sure the main unit power switch is turned OFF.
Disconnect the negative (-) lead at the battery before making any power connections.
When making connections, be sure that each connection is clean and secure. Insulate final
connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.
= A secure, clean ground connection is critical to the performance of your Clarion car audio
amplifier. Use the shortest ground wire possible to minimize resistance and avoid noise
problems.
" Add an external fuse (830A) on the positive (+) power lead and connect it as close as possible to
the vehicle's (+) battery terminal. Adding an external fuse will protect the electrical system from
short-circuits that can cause fire.
- Refer to Figure — "Electrical Connections” when making electrical connections. Connect the
amplifier's positive (+) power lead via a fuse directly to the positive (+) terminal on the car battery.
Do not connect this wire to the cars fuse panel. Use red-insulated 8-gauge wire for the
amplifier's positive (+) power lead and the same gauge black-insulated wire for the ground.
= Since the speaker output terminal and power supply terminal of this product are block-type
terminals, the tip of each connection code should make connection after about 1cm strip
processing of the wire. To avoid short circuit, please tightly lock the terminal when doing the
wiring. Also regular inspection is recommended on terminal for loosen connection.
" When replacing the amplifier's fuse, always use one having the same current rating (30A).
Substituting with a higher-rated fuse can reduce protection and may result in serious damage to
the amplifier.
= Never ground the speakers to the vehicle chassis or body.
: Make sure that your vehicle's electrical system (i.e., alternator, battery, etc.) is capable of
handling the additional load.
= To avoid possible noise problems, run the amplifier's positive (+) power lead along one side of
the vehicle to the battery. Run the remote turn-on wire and RCA audio cable down the center,
and route the speaker wires along the remaining side. If wires must cross, run them
perpendicular to each other.
- When creating passage holes for the power wire, use grommets to eliminate any sharp edges
created during drilling. This will protect the wire from bring nicked and causing a short-circuit.
= Extra cable cause signal loss and act as an "antenna" for noise. Use only high-quality RCA
cables that are no longer than necessary to make a direct connection with the main unit or
equalizer.

Caution:
When Subwoofer starts "pop" (electrical overload), please lower gain control volume and avoid the
damage to subwoofer. If the sound of subwoofer begins to produce muddiness and distortion
(amplifier allophone), please lower gain control volume, avoid that amplifier lapses into a regular
functional stop state by fault load, and wait to recover clear low-pitched sound region sensitivity.
Adjustment of an electronic crossover function (HP/LP):
Caution:
Clarion recommends turning the amplifier off before changing any switch position.
This will eliminate any possible damage from transient spikes to the amilfier or speaker system
while changing the switch setting.
(1) HP filter function (mid-range / high region speaker correspondence) setup :
LPF/HPF control set to 125Hz is recommended. Listen to a variety of music style (Rock, Rap,
R&B, etc---) and slowly increase or decrease the LPF/HPF control until the best performance is
realized. For most a mid range speaker, the crossover point tends to be around 100Hz. Setting
the crossover frequency too low may cause distortion is produced on a high reproduction level.
In addition to it, there is a possibility of damaging usage's speaker. If such a situation occurs,
please raise crossover frequency (please turn LPF/HPF control unit adjustment volume
clockwise), and reduce distortion.
(2) LP filter function (subwoofer correspondence) setup :
LPF/HPF control set to 55Hz (the position turned to the limit of a counterclockwise rotation)
is recommended. Listen to a variety of music style (Rock, Rap, R&B, etc---) and slowly increase
or decrease the LPF/HPF control until the best performance is realized. For mosf subwoofer
systems, the crossover point tends to be between 55Hz and 120Hz.
Setting the crossover frequency too high may cause audio system to sound "boomy" or vocals
and speech to become very "nasal" in tone.
IN Speaker Level Input
When you connect with a car audio without a RCA output terminal, please use a speaker level
input terminal.
Caution :
Noise or pop sound may be made by a car audio to combine with this amplifier or by a position
of a level of gain of this amplifier.

~O FINAL SYSTEM CHECKS
1. Start the engine and turn on the main unit.
After a short two-second delay, slowly raise
the volume and listen to the sound. If you
hear any noise, static, distortion or no
sound at all, check the connections, and
also refer to the “Troubleshooting”
section. Depending on your system design,
the levels may become quite loud even
care when adjusting the controls.
2. Adjust the balance control from left to right
and listen to the result. Audio imaging
should match control setting.
3. Increase the volume and verify that the
APA2160 amplifier reproduces audio
without distortion at all frequencies. If you
hear distortion, check the connections and
verify that the gain controls is set correctly.
Another possibility is damaged ( or under-
powered) speakers. Once again, refer to
the "Troubleshooting" section for
additional help.
