for your installation placement preference.
• When running power cables through sheet metal it is best to use
grommets and loom to properly insulate the metal edges.

Mounting Placement
The AP-9EQ was designed to be installed in or near the
dashboard of most vehicles. The front panel was designed
so that the equalizer would be mounted ush to your vehicles’
dash. There are dash kits from many brands that allows for the
equalizer to be mounted alongside your headunit. Check with your
Authorized Aunex Dealer for additional information and options.
Other popular mounting options are under the dashboard or in
your glove compartment. For these methods, you will use the
supplied mounting brackets as shown below. Make sure there
are no items behind the area where the screws will be driven.
For optimum sound quality, it is highly recommended that you
purchase Aunex wiring accessories as they are designed to give
your equalizer and ampliers the high-quality signal it needs to
operate at peak performance levels. Aunex has everything from
RCA cables and power wire to speaker wire and battery connectors.

1. Main Volume: This inner knob controls the volume level of your
Front, Rear and Subwoofer outputs. It is recommended that you
set your radio volume at the desired listening level and make
your sound adjustments from your equalizer.
2. Fader: This outer knob on the Main Volume Control will allow you
to fade the signal level between your Front and Rear outputs.
This will allow you to have Front and Rear fading capabilities with
only one pair of inputs.
3. Subwoofer Volume: This inner knob controls the volume level
of your Subwoofer Outputs. The Main Volume Knob will also decrease
the volume of your subwoofer output but will not increase
the output of the subwoofer(s) volume pass where the Subwoofer
Volume Knob is set to.
4. Subwoofer Frequency: This outer knob allows you to select
the center frequency range of your subwoofer output from 40Hz
to 150Hz.
5. Dual Input Selector: This button allows you to select the input
signal from either your main Head Unit or Aux Input.
6. Equalizer Knobs: These 9 knobs allow you to control 9 bands
of equalizations (Bass) 80Hz, 120Hz, (Upper Bass to Lower
Midrange) 200Hz, 500Hz, (Midrange) 1kHz, (Upper Midrange)
3kHz, (Presence / Sibilance Register) 6kHz, (Brilliance / Sparkle
Register) 10kHz and (Open Air) 15kHz with a 18dB of defeat or
boost.

1. Power Connector: This connector has inputs for Ground,
Remote and Power.
a. Ground: Use the same gauge wire that is being used for the
Power connection and run your ground wire to this negative
terminal. Good ground points are from your battery, a ground
buss or a veried ground location that is clean. This will
minimize the possibility of noise induced into the system.
(Factory head unit ground is not recommended as it can
induce unwanted noise.)
b. Remote: Use a 22 to 18 Gauge wire from your head unit’s
remote turn-on (+12VDC Switched) and run it to remote
terminal.
c. Power: Use the supplied in-line fuse and connect it to a
constant positive +12 volt source. Use the same gauge wire
that is used for the ground; preferably 18 Gauge or larger and
run it to the +12 Volt terminal.
2. Auxiliary Input: This rear 3.5mm input jack allows you to
connect your phone or portable audio player directly to your
equalizer. Be sure to select Aux Input mode when in use from
the front panel button.
Low Level RCA Connections: Aunex recommends using high
quality RCA Interconnects such as the Aunex AP RCA and AE
RCA series. Consult with your Authorized Aunex Dealer to see
what cable and length works best for your installation. (Note:
Avoid crossing your power and wire ground with your RCA
cables. This will help prevent noise interference.)
3. Main: Use this pair of inputs to connect your main source /
headunit.

4. Subwoofer: Use this pair of outputs to connect to your
subwoofer amplier or subwoofer channels of your amplier.
5. Front: Use this pair of outputs to connect to your front amplier
or front channels of your amplier.
6. Rear: Use this pair of outputs to connect to your rear amplier
or rear channels of your amplier.
The above example illustrates the most common use of the
AP-9EQ utilizing 3 ampliers and a headunit.

Tuning the 9 Bands of equalization is set by your listening
preference as dierent music genre are produced with
dierent quality and dierent equalizations. The AP-9EQ was
designed to help you compensate these recording dierences by
allowing you to ne tune your system for your listening enjoyment.
The 9 Bands of equalization does not aect your
subwoofer channel as your subwoofer channel already has its
own independent frequency range and volume knob. Instead the
equalization bands will only aect the Front and Rear Outputs.
- Bass (80Hz Centered): Use this knob sparingly as most
coaxials speakers and components cannot handle 18dB of
boost. However, in some music you will nd that turning up this
knob will enhance the low frequency output.
- Upper Bass (120Hz Centered): Use this knob to control
frequencies that are above subwoofer bass and below midrange
which is also called low order harmonics. This range is normally
associated with Male vocals, brass instruments.
- Upper Bass (200Hz Centered): Use this knob to control
frequencies that are associated lower end of vocals, deeper
notes from synthesizers, low brass and piano.
- Lower Midrange (500Hz Centered): Use this knob to control
the lower midrange frequencies. Adding to much boost in this
region makes things sound muddy and congested. Not adding
enough boost in this region can make sound seem thin and weak.
- Midrange (1kHz Centered): Use this knob to control the
midrange frequencies. Adding volume here should be used
sparingly as too much can give things a metallic sound and
can wear down on your ears quickly if raised too much.
- Upper Midrange (3kHz Centered): Use this knob to control the
upper midrange frequencies. Adding or reducing here can raise
or lower the snap of higher instrumentation quickly such as
acoustic and electric guitar and piano.

- Presence / Sibilance Register (6kHz Centered): Use this knob
to control what is referred to as the presence zone and includes
the highest range of pitches produced by most natural
instruments. Boosting this range can make the music sound more
forward. Reducing this range can open the sound and push
instruments away for more depth.
- Brilliance / Sparkle Register (10kHz Centered): Use this knob
to increase or decrease the vibrancy and clarity of this frequency
region. The sound of cymbal oats around this region.
- Open Air (15kHz Centered): Use this knob to control the higher
overtones of instrumentation and synth eects from electronic
music. Boosting this region too much can make things start to
sound synthetic.
